Mexico, with a population of 122 million is the most populous Spanish-speaking country in the world. The country is known for its Pacific and Gulf of Mexico beaches and its diverse landscape of mountains, deserts and jungles. Ancient ruins such as Teotihuacan (Aztec), Chichen Itza (Mayan) and Spanish colonial-era towns are scattered throughout the country.

Originating from the lakes of Eastern, Central and Western Africa, the Nile tilapia (Oreochromis niloticus) was first introduced to developing countries as a cheap, easy way for subsistence farmers to provide their families with enough protein. With improved production techniques and methods of controlling its flavour, the fish became more of a mainstream product. Communities of migrants from these countries then created a market for tilapia in the developed nations they had moved to, and finally a taste for the fish spread amongst the locals.
Rescue and handling of Antillean manatees Trichechus manatus manatus in Venez...ConBiVe
Given the importance of the rescue and rehabilitation
of confiscated manatees from illegal traffic or accidental
fishery entanglements, the handling and transport of
two Antillean manatees Trichechus manatus manatus
in the ‘Llanos’ of Apure state in Venezuela is
described. In 1992, two ♀ calves were confiscated in
the region of Arichuna in the Apure River and transported
to a lagoon at the Fondo Nacional de Investigaciones
Agropecuarias, Biruaca, for rehabilitation. Data
about age, size, weight and haematological values were
recorded. In 1994, one of the manatees was transferred
to the Parque Zoologico y Botanico Bararida, Barquisimeto,
in order to form a breeding pair and start a
captive-breeding programme. Successful reproduction
was achieved in 2007, 2011 and 2013. In 1995, the
second ♀ Antillean manatee was released into a natural
environment in Santa Luisa Cattle Ranch, Apure state.
The confiscation, rescue, rehabilitation and transport
(by land and air) of these two ♀ Antillean manatees
were carried out satisfactorily.

In the past 50 years, the global demand for fish products has doubled, and more than 45 percent of the world’s seafood today now comes not from wild catches, but from either land-based or offshore fish farms. To meet this rising demand for seafood worldwide, more fish have to be raised in fish farms, and aquaculture is an essential link in the agricultural chain.
Brewers’ yeast and derived products have been successfully used in animal nutrition, including aquafeeds, for several decades now. Leiber GmbH, with two production sites in Germany and further facilities in Poland and Russia, have manufactured brewers’ yeast products for more than 60 years.
Carbohydrates are an excellent source of energy and carbon in feed formulations. They can be easily distinguished from the other energy yielding nutrients in terms of their abundance and low price. To illustrate, the collective global production of the major cereal grains i.e., maize, wheat and rice amounted to a colossal 2.5 billion tonnes in the year 2013 (FAO). The total carbohydrate content and the digestible fraction of starch and sugars in these grains can be roughly estimated to be about 2.1 and 1.75 billion tonnes, respectively (www.feedipedia.org). Besides, the unit cost of carbohydrate sources is almost three to five fold less than that of the protein and lipid sources of interest. Therefore, the inclusion level of carbohydrates in commercial fish feed assumes direct economic significance i.e., in terms of lower feed cost per unit weight gain.
From both nutritionist and aquaculturist points of view, our aim is to sustainably produce aquatic food with superior sensory properties and high cardioprotective properties.

The composition of aquafeeds and their impact on the nutritional value of aquatic food is a focal point of today’s research and development both in academia and industry.
The quality and digestibility of proteins is one of the most important issues in shrimp nutrition. Marine proteins (mainly fish meal) can only be partially replaced by standard vegetable proteins like soybean meal.

With an estimated market value of over £1.8 billion and Scottish salmon exports alone reaching over £500 million, Scotland’s aquaculture sector is fast becoming a core pillar for the future growth of the Scottish economy. However, with such a steep increase in the demand for fish products, there is a real need for innovation within the sector to stay ahead of the curve and provide a sustainable supply of healthy protein; not only for the present but for the future of a market that appears set to keep growing. Ahead of Aquaculture UK, CEO of the Scottish Aquaculture Innovation Centre (SAIC), Heather Jones, shares some of the organisation’s forays into finfish research projects and the ways in which is working with both industry and academia to enhance the whole of the Scottish aquaculture sector.

The Salmonidae family, collectively known as Salmonids, comprises of salmon, trout, chars, freshwater whitefishes, and graylings, but it is the trout and Atlantic salmon, of the genus Salmo, which gives the family their name. A slender teleost fish, they can range in size between just 13 cm to a whopping 2 m in length. With a single row of sharp teeth, Salmonids are predators, choosing to feed on smaller fish, aquatic insects and small crustaceans. Despite spawning in fresh water Salmonids are mostly anadromous, spending their lives at sea, choosing only to return to rivers to reproduce.

The European lobster (Homarus gammarus) is an ecologically important species of the North-eastern Atlantic which supports wild trap fisheries that are worth around £30 million each year to the UK alone. By weight the species is the highest-value seafood among those landed regularly in the UK and Ireland, where 75 percent of the ~5,000t annual landings for the species are made. As such, lobsters provide essential diversity to fragile inshore fisheries and vital income for rural coastal economies. However, populations across its range are pressured by rising exploitation, from which traditional fisheries management has failed to prevent extensive regional stock collapses in the recent past, and now struggles to stimulate recovery. While lobsters have long been transported as a live export commodity, chiefly to France and the Iberian peninsula, emerging markets, particularly those in East Asia, threaten to create additional demand for the species which far exceeds current capture yields. Improvements in hatchery rearing success have seen a number of recent aquaculture initiatives employed, in the hope of both generating restoration and improved sustainability of wild harvests, and instigating commercial aquaculture possibilities.
Mud crabs, also known as mangrove crabs, occur widely in estuaries and along tropical, subtropical and warm temperate coasts in the world.

The Asian catfish Pangasius, Pangasianodon hypophthalmus is recognised as a leading aquaculture food fish on world markets. The commercial culture of Pangasius was developed in the mid 1990’s in Vietnam and quickly expanded to production levels of nearly one million tons per year. Other countries including Thailand, Cambodia, Myanmar, Indonesia, Philippines, Bangladesh and India have adapted Pangasius as part of their aquaculture production. Pangasius can be successfully cultured in most tropical regions of the world however countries in the Western Hemisphere have been slow to embrace Pangasius aquaculture, in part, due to the lack of practical knowledge of the species food requirements during the larval and fry stages.

The Rockefeller Foundation marks its 100th year in 2013. The Foundation’s mission, unchanged since 1913, is to promote the well-being of humankind throughout the world. During the course of its history, the Foundation has supported the ingenuity of innovative thinkers and actors by providing the resources, networks, convening power, and technologies to move innovation from idea to impact. It supports work that expands opportunity and strengthens resilience to social, economic, health, and environmental challenges. The Foundation seeks to achieve its mission through work aimed at meeting four equally important goals: revalue ecosystems, advance health, secure livelihoods, and transform cities.
Starting in June 2012, the Rockefeller Foundation began investigating the pressing problem of the declining health of the oceans due to climate change, overfishing, pollution and habitat destruction, and the effects of this decline on poor and vulnerable people who depend on marine ecosystems for food and livelihoods. The goal was to better understand the nature of the problem and the potential impact of interventions in the fields of fisheries, aquaculture, poverty, and food security.
The Foundation assembled a portfolio of learning grants that examined this problem from multiple perspectives in order to inform and assess the viability of and potential impact for future engagement on this topic. We supported four scoping studies that sought to identify populations dependent on marine fisheries, as well as review past experience with integrated approaches to fisheries management within a livelihoods and food security context. In partnership with Bloomberg Philanthropies, we also supported scoping work in four countries to assess opportunities for a coordinated strategy integrating national policy, local management, and innovative financing.
We have learned a tremendous amount from the work our grantees have done, captured here by partner FSG in a summary and synthesis. We hope this information will contribute to the broader body of knowledge on this topic, as well as our own work.
American Journal of Multidisciplinary Research and Development is indexed, refereed and peer-reviewed journal, which is designed to publish research articles.

Best 10 Economic Importance Of Aquaculture
Aquaculture
Fisheries and aquaculture make a big contribution to development in the areas of employment. Describing the importance of aquaculture is not an easy task. According to M. Shahbandeh, the number of people who were engaged in fishing and aquaculture amounted to around 40.34 million and 19.27 million respectively worldwide in 2016 and the number has been increasing day by day since 1995. The vast majority of them are from developing countries, working in fish production or fish raising, fish processing, harvesting, and small-scale fish business.

Table of Contents
Aquaculture
Aquaculture is the controlled process of rearing, breeding and harvesting of aquatic species, both animals and plants, especially for human consumption, though it is controlled aquatic environments like the oceans, lakes, rivers, ponds, and streams. It’s a similar conception to agriculture, but with fish instead of plants or livestock. It also serves various functions such as food production, restoration of threatened and endangered species populations, wild stock population enhancement, the building of aquariums, and fish cultures, and habitat restoration.
History of Aquaculture
The husbandry of fish is therefore not a new phenomenon. Ancient practices based on the modifications of natural bodies of water or wetlands to entrap young fish in enclosures until harvest have just evolved into more systematic and scientific methods and techniques.
Aquaculture has a long tradition, which is about 4 000 years, and form the beginning of the time man identified the importance of aquaculture.. Probably aquaculture began in China before very long ago, due to the wants of an emperor to have an unremitting supply of fish in his land. It is supposed that the proficiencies for keeping fish in ponds originated in China with fishermen who kept their extra catch alive temporarily in baskets submerged in rivers or small bodies of water created by damming one side of a river bed.(Ling, S.W,Aquaculture in Southeast Asia: A Historical Overview,A Washington Sea Grant Publication).
Another theory is that aquaculture arose from ancient practices for pinning down fish, with the operations steadily improving from trapping-holding to trapping-holding-growing, and finally into complete agriculture or farming practices.
Methods of Aquaculture
The methods of aquaculture’s farm-to-table process can differ from species to species. Generally, there are four stages of the production chain, starting in hatcheries and ending at the seafood counter in your grocery store. Four stages are:
stages of the production chain

Each of these stages may vary concerning its effect on the environment and the quality and safety of the seafood they produce.

Much has been made of gut health recently. By unpacking the concept, we can arrive at a better understanding of the driving factors, influences, indicators and implications of gut health for aquaculture.

Mycotoxin contamination of feed stuff often involves multiple toxins affecting various aspects of animal health, gut integrity, and animal performance. This is mainly caused by the detrimental effects mycotoxins have on the immune system, the gut barrier or the oxidative status of the animals. Effects that can be seen are, for instance, enlarged or shrunken organs as well as inflamed tissues. Binding components efficacy is essential to prevent the maximum of toxins from entering the digestive tract.
Dr Eckel has been selling feed additives since 1994. One of our core competencies is the utilisation of organic acids and their salts for animal nutrition – either as silage enhancers, as preservatives or as acidifiers. Acidifiers are well established in pig and poultry nutrition – especially of young animals (piglets and broiler chicks). The concept of acidifiers has been successfully transferred from agriculture feed to aquaculture feed during the last 10 years.
Back in the 13th century, maybe even earlier, it has been recorded that when people travelled in Europe they were often given dried seaweed on arrival at their destination to nourish them after their tiring efforts.

Nutraceutical market, scope and growth: Herbal drug technologyLokesh Patil
As consumer awareness of health and wellness rises, the nutraceutical market—which includes goods like functional meals, drinks, and dietary supplements that provide health advantages beyond basic nutrition—is growing significantly. As healthcare expenses rise, the population ages, and people want natural and preventative health solutions more and more, this industry is increasing quickly. Further driving market expansion are product formulation innovations and the use of cutting-edge technology for customized nutrition. With its worldwide reach, the nutraceutical industry is expected to keep growing and provide significant chances for research and investment in a number of categories, including vitamins, minerals, probiotics, and herbal supplements.
Richard's entangled aventures in wonderlandRichard Gill
Since the loophole-free Bell experiments of 2020 and the Nobel prizes in physics of 2022, critics of Bell's work have retreated to the fortress of super-determinism. Now, super-determinism is a derogatory word - it just means "determinism". Palmer, Hance and Hossenfelder argue that quantum mechanics and determinism are not incompatible, using a sophisticated mathematical construction based on a subtle thinning of allowed states and measurements in quantum mechanics, such that what is left appears to make Bell's argument fail, without altering the empirical predictions of quantum mechanics. I think however that it is a smoke screen, and the slogan "lost in math" comes to my mind. I will discuss some other recent disproofs of Bell's theorem using the language of causality based on causal graphs. Causal thinking is also central to law and justice. I will mention surprising connections to my work on serial killer nurse cases, in particular the Dutch case of Lucia de Berk and the current UK case of Lucy Letby.
THE IMPORTANCE OF MARTIAN ATMOSPHERE SAMPLE RETURN.Sérgio Sacani
The return of a sample of near-surface atmosphere from Mars would facilitate answers to several first-order science questions surrounding the formation and evolution of the planet. One of the important aspects of terrestrial planet formation in general is the role that primary atmospheres played in influencing the chemistry and structure of the planets and their antecedents. Studies of the martian atmosphere can be used to investigate the role of a primary atmosphere in its history. Atmosphere samples would also inform our understanding of the near-surface chemistry of the planet, and ultimately the prospects for life. High-precision isotopic analyses of constituent gases are needed to address these questions, requiring that the analyses are made on returned samples rather than in situ.
Observation of Io’s Resurfacing via Plume Deposition Using Ground-based Adapt...Sérgio Sacani
Since volcanic activity was first discovered on Io from Voyager images in 1979, changes
on Io’s surface have been monitored from both spacecraft and ground-based telescopes.
Here, we present the highest spatial resolution images of Io ever obtained from a groundbased telescope. These images, acquired by the SHARK-VIS instrument on the Large
Binocular Telescope, show evidence of a major resurfacing event on Io’s trailing hemisphere. When compared to the most recent spacecraft images, the SHARK-VIS images
show that a plume deposit from a powerful eruption at Pillan Patera has covered part
of the long-lived Pele plume deposit. Although this type of resurfacing event may be common on Io, few have been detected due to the rarity of spacecraft visits and the previously low spatial resolution available from Earth-based telescopes. The SHARK-VIS instrument ushers in a new era of high resolution imaging of Io’s surface using adaptive
optics at visible wavelengths.

Earliest Galaxies in the JADES Origins Field: Luminosity Function and Cosmic ...Sérgio Sacani
We characterize the earliest galaxy population in the JADES Origins Field (JOF), the deepest
imaging field observed with JWST. We make use of the ancillary Hubble optical images (5 filters
spanning 0.4−0.9µm) and novel JWST images with 14 filters spanning 0.8−5µm, including 7 mediumband filters, and reaching total exposure times of up to 46 hours per filter. We combine all our data
at > 2.3µm to construct an ultradeep image, reaching as deep as ≈ 31.4 AB mag in the stack and
30.3-31.0 AB mag (5σ, r = 0.1” circular aperture) in individual filters. We measure photometric
redshifts and use robust selection criteria to identify a sample of eight galaxy candidates at redshifts
z = 11.5 − 15. These objects show compact half-light radii of R1/2 ∼ 50 − 200pc, stellar masses of
M⋆ ∼ 107−108M⊙, and star-formation rates of SFR ∼ 0.1−1 M⊙ yr−1
. Our search finds no candidates
at 15 < z < 20, placing upper limits at these redshifts. We develop a forward modeling approach to
infer the properties of the evolving luminosity function without binning in redshift or luminosity that
marginalizes over the photometric redshift uncertainty of our candidate galaxies and incorporates the
impact of non-detections. We find a z = 12 luminosity function in good agreement with prior results,
and that the luminosity function normalization and UV luminosity density decline by a factor of ∼ 2.5
from z = 12 to z = 14. We discuss the possible implications of our results in the context of theoretical
models for evolution of the dark matter halo mass function.
Cancer cell metabolism: special Reference to Lactate PathwayAADYARAJPANDEY1
Normal Cell Metabolism:
Cellular respiration describes the series of steps that cells use to break down sugar and other chemicals to get the energy we need to function.
Energy is stored in the bonds of glucose and when glucose is broken down, much of that energy is released.
Cell utilize energy in the form of ATP.
The first step of respiration is called glycolysis. In a series of steps, glycolysis breaks glucose into two smaller molecules - a chemical called pyruvate. A small amount of ATP is formed during this process.
Most healthy cells continue the breakdown in a second process, called the Kreb's cycle. The Kreb's cycle allows cells to “burn” the pyruvates made in glycolysis to get more ATP.
The last step in the breakdown of glucose is called oxidative phosphorylation (Ox-Phos).
It takes place in specialized cell structures called mitochondria. This process produces a large amount of ATP. Importantly, cells need oxygen to complete oxidative phosphorylation.
If a cell completes only glycolysis, only 2 molecules of ATP are made per glucose. However, if the cell completes the entire respiration process (glycolysis - Kreb's - oxidative phosphorylation), about 36 molecules of ATP are created, giving it much more energy to use.
IN CANCER CELL:
Unlike healthy cells that "burn" the entire molecule of sugar to capture a large amount of energy as ATP, cancer cells are wasteful.
Cancer cells only partially break down sugar molecules. They overuse the first step of respiration, glycolysis. They frequently do not complete the second step, oxidative phosphorylation.
This results in only 2 molecules of ATP per each glucose molecule instead of the 36 or so ATPs healthy cells gain. As a result, cancer cells need to use a lot more sugar molecules to get enough energy to survive.

introduction to WARBERG PHENOMENA:
WARBURG EFFECT Usually, cancer cells are highly glycolytic (glucose addiction) and take up more glucose than do normal cells from outside.
Otto Heinrich Warburg (; 8 October 1883 – 1 August 1970) In 1931 was awarded the Nobel Prize in Physiology for his "discovery of the nature and mode of action of the respiratory enzyme.
WARNBURG EFFECT : cancer cells under aerobic (well-oxygenated) conditions to metabolize glucose to lactate (aerobic glycolysis) is known as the Warburg effect. Warburg made the observation that tumor slices consume glucose and secrete lactate at a higher rate than normal tissues.

Extrachromosomal Inheritance
Slide 2: Introduction to Extrachromosomal Inheritance
Definition: Extrachromosomal inheritance refers to the transmission of genetic material that is not found within the nucleus.
Key Components: Involves genes located in mitochondria, chloroplasts, and plasmids.
Slide 3: Mitochondrial Inheritance
Mitochondria: Organelles responsible for energy production.
Mitochondrial DNA (mtDNA): Circular DNA molecule found in mitochondria.
Inheritance Pattern: Maternally inherited, meaning it is passed from mothers to all their offspring.
Diseases: Examples include Leber’s hereditary optic neuropathy (LHON) and mitochondrial myopathy.
Slide 4: Chloroplast Inheritance
Chloroplasts: Organelles responsible for photosynthesis in plants.
Chloroplast DNA (cpDNA): Circular DNA molecule found in chloroplasts.
Inheritance Pattern: Often maternally inherited in most plants, but can vary in some species.
Examples: Variegation in plants, where leaf color patterns are determined by chloroplast DNA.
Slide 5: Plasmid Inheritance
Plasmids: Small, circular DNA molecules found in bacteria and some eukaryotes.
Features: Can carry antibiotic resistance genes and can be transferred between cells through processes like conjugation.
Significance: Important in biotechnology for gene cloning and genetic engineering.
Slide 6: Mechanisms of Extrachromosomal Inheritance
Non-Mendelian Patterns: Do not follow Mendel’s laws of inheritance.
Cytoplasmic Segregation: During cell division, organelles like mitochondria and chloroplasts are randomly distributed to daughter cells.
Heteroplasmy: Presence of more than one type of organellar genome within a cell, leading to variation in expression.
Slide 7: Examples of Extrachromosomal Inheritance
Four O’clock Plant (Mirabilis jalapa): Shows variegated leaves due to different cpDNA in leaf cells.
Petite Mutants in Yeast: Result from mutations in mitochondrial DNA affecting respiration.
Slide 8: Importance of Extrachromosomal Inheritance
Evolution: Provides insight into the evolution of eukaryotic cells.
Medicine: Understanding mitochondrial inheritance helps in diagnosing and treating mitochondrial diseases.
Agriculture: Chloroplast inheritance can be used in plant breeding and genetic modification.
Slide 9: Recent Research and Advances
Gene Editing: Techniques like CRISPR-Cas9 are being used to edit mitochondrial and chloroplast DNA.
Therapies: Development of mitochondrial replacement therapy (MRT) for preventing mitochondrial diseases.
Slide 10: Conclusion
Summary: Extrachromosomal inheritance involves the transmission of genetic material outside the nucleus and plays a crucial role in genetics, medicine, and biotechnology.

1. MEXICO
M
exico, with a population
of 122 million is the most
populous Spanish-speaking
country in the world. The
country is known for its
Pacific and Gulf of Mexico
beaches and its diverse
landscape of mountains,
deserts and jungles. Ancient
ruins such as Teotihuacan (Aztec), Chichen Itza (Mayan) and
Spanish colonial-era towns are scattered throughout the country.
Infectious Mariachi music, sombreros and vitamin ‘T’ are
also some of the great highlights. Vitamin ‘T’ includes Tacos,
Tostados, Tamales, Taquitos, Tortas and Tortillas all washed down
with Tequila.
Rather cheekily last year, Mexico offered some US based
aquaculture businesses the opportunity to raise their fish south of
the border where they promised regulaters had a more modern
approach to offshore aquaculture than they could experience in
their own country.
Mexico has recently become serious about aquaculture
Mexico has in the last few years become a serious aquaculture
country and there is a major effort by Mexican offshore fish
farmers and government officials to make their country ‘the
place’ for raising fish offshore in North America.
Aquaculture is supported in Mexico by the Federation through
the Secretariat of Agriculture, Livestock, Rural Development,
Fisheries and Food (SAGARPA) and CONAPESCA. The head
of the National Commission of Aquaculture and Fisheries
(CONAPESCA), Mario Aguilar Sánchez has said on many
occasions that boosting aquaculture provides “a great opportunity
to contribute to the growth of the industry, with products having
nutritional and protein quality available to Mexicans,” according
to press reports.
Mexico has indeed gone further than most countries in the
area of seafood consumption and understanding the need for
promotion and marketing and this is assisting the drive/desire for
aquaculture.
In 2012 the National Institute of Statistics and Geography
(INEGI) completed a survey and found that Mexican households
spent monthly 34 percent of their income in food, out of which
8.5 percent was seafood, Of the 31.5 million households that
were surveyed by, on average , only 24.4 percent said that their
food basket are included seafood. The indications at that stage
showed Mexican seafood consumption at around the 9kgs per
person per annum.
Mexico has been mentioned as being in the top three
countries in terms of obesity, and Coneval, the government’s
social development agency, has advised that the poverty rate
is approximately 46.2 percent of Mexico’s population, and
equivalent to 55.3 million people. Coneval defines poverty as
living on no more than 2,542 pesos ($157.70) a month in cities
and 1,615 pesos in rural areas.

2. Utilising the survey the Commissioner produced a paper
“Fisheries and aquaculture, and its impact on Mexico’s food
security,” highlighting that in Mexico the fishing and aquaculture
sectors contribute significantly to the development and welfare
of large segments of the population, especially in rural and
regional areas. At present, approximately 25 percent of Mexico’s
population lives rurally.
Following meetings in 2013 and participating in a forum
organised by the FAO , ‘Sustainable Food Systems - A
comprehensive policy on food and nutrition’ the Commissioner
said “Mexico is seeking to increase fish and shellfish
consumption per capita in the next decade. The implementation
by the Government of the new fisheries/aquaculture policy will
enable Mexico to increase per capita consumption of seafood
over the next decade.”
It has been well demonstrated that fish and shellfish are an
important source of nutrients of animal protein and one of the
pillars of the National Crusade Against Hunger, recognised by
CONAPESCA. As a result of the policies and strategies for the
development of aquaculture and fisheries in Mexico, from 2013
to 2018 there is an emphasis on the promotion of consumption of
fishery and aquaculture products.
One of the other important strategies of the SAGARPA/
CONAPESCA is the annual Foro Economico de Pesca y
Acuacultura, which enables industry and government to engage,
discuss and update. These events are usually held in November in
Mexico City and at the last one, which was attended by over 1500
people we learned that consumption has increased to about 13kgs
per person per annum.
Currently Mexico’s most important aquaculture activity is based
in the north west of the country, is based on Shrimp and in 2015
was 110,000 tonnes. Cultivated shrimp now accounts for almost
70 percent of total national production; with the heart of this
transition being the states of Sinaloa and Sonora. The industry
with support of the government is fighting their way back from
disease issues, which have had an impact in many other countries
besides Mexico.
The impact of Early Mortality Syndrome on Mexican
fishing
The disease, Early Mortality Syndrome (EMS), ensured that
the production of farmed shrimp dropped sharply between 2012
and 2013, but is now in full recovery and expansion. EMS first
appeared in 2009 in the southern part of China, and then spread
to Vietnam, Malaysia and Thailand. SAGARPA reported that
the disease shows up in the first 20 to 30 days of life of the
shrimp, and especially affects tiger (Penaeus monodon) and white
(Litopenaeus vannamei) shrimp. The disease adversely impacted
thousands of producers, with shrimp mortality rates as high as 98
percent.
The strain of EMS found in Mexico is very similar (but not
identical) to the Asian strain. It is unclear how it arrived in
Mexico and whether or not it was transferred across the Pacific.
CONAPESCA’s figures highlight that Shrimp aquaculture

and Sardines combined in Mexico. They also point out that the
recovery has been mainly because of the process engaged in
aquaculture. The ponds utilised are emptied and dried for a whole
season, not because of any regulation but because the producers
have initiated improved systems and methods. Additionally the
producers have an excellent program aiming to select strains of
Shrimp more for resistance rather than growth.
The largest potential for aquaculture expansion in
Mexico is Tilapia
Dr. Antonio Garza de Yta, has been in the role of Director
General de Planeación, Programación y Evaluación at
CONAPESCA for the last two years and is very proud of
Mexico’s activities in both fisheries and aquaculture.
“The largest potential for aquaculture expansion in Mexico
is Tilapia in the South; Catfish in the North; Shrimp along all
the coast especially using super intensive systems; Oysters in
Tamaulipas and Baja California and Sea Cucumber in Baja
California and Yucatan. There have been many local species
evaluated for potential growth but no successful culture has been
developed at this stage.” Stated Dr. Antonio Garza de Yta, adding
that
“There is good interest in Yellowtail species and Totoaba
(Totoaba macdonaldi) which is listed on CITES, the IUCN
Red List of Threatened Species, and the Endangered Species
Act (ESA) is formerly endemic in the Gulf of California has
some potential to be the ‘Mexican Salmon’ through aquaculture
– fish growth has been measured at 9 grams per day. Within
CONAPESCA our priorities at this stage are to continue to
improve our management measures, zoning and policies for
Aquaculture.” It would be true to say that Mexico has the
potential to produce more than 2 million MTs per annum,
however, in order to achieve that it needs a whole of government
approach to recognise aquaculture as a priority and to include
items such as power tariffs, accessible
electricity and other important infrastructure
issues.
Over the past few years some US based
aquaculture companies have decided to
farm their fish offshore in Mexican waters.
There are good examples in tuna ranching,
sea bass, yellowtail, and hybrid striped bass
which are now farmed in Mexican waters.
What is clear is that Mexico’s government
and private sector are working hand-in-
hand to build an industry that can be an
alternative but time will see if that continues
as and when US offshore fish-farming gets
off the drawing table.
Regal Springs: A 21st Century
Aquaculture Business
Regal Springs’ is what might be termed a
21st century aquaculture business and has
a solid background in both sustainable and
social areas specialising in eco-balanced
Tilapia. One of its newest operations is
nestled in the lush, green hills of Chiapas,
Mexico. The facilities consist of a hatchery,
juvenile fry nursery, floating grow-out cages
and a state of the art production facility.
Lake Penitas, on which the tilapia are raised
in floating cages, boasts pure, fresh water
surrounded by unspoiled natural beauty. Once grown, the fish are
processed in a cutting edge production facility.
The facility is able to accommodate 40-50 metric tons of frozen
storage capacity in addition to fresh processing and custom
cutting. When fully operational, the production facility alone will
employ 850 to 1000 local residents.
Regal Springs are noted for adding value to communities with
whom they engage and they have stated that they are committed
to supporting the Chiapas community, as they have done in
Honduras and Indonesia. Regal Springs also have many projects
in the pipe-line which include supporting the opening of a new
school and pledging support for the Ocote Jungle Biosphere
Reserve.
Framed by the Sierra de las Viente Casas (Twenty Houses of
Sierra) mountain range, it has almost 50 thousand hectares and
was created in 1982 for the preservation of the flora and fauna in
the northern region of the state of Chiapas.
Mexico and the need for capacity and capability
The Blue Economy and along with the recent and various Trade
Agreements are enormous prospects for Mexico and the need
for capacity and capability building is crucial and is a major
challenge. Food Safety and Workplace Health and Safety are
essential elements amongst the main education needs. Without
these important foundations attracting the right investors/
investments will be difficult.
Like with all governments, there is a struggle with changing
from the typical evolution of departments of fisheries to employ
more aquaculture experts who have a broader training than just
capture fisheries but also in aquaculture, in conservation, and in
changing ecosystems. There is need for a new paradigm of the
roles.
Dr. Garza de Yta is confident that Mexico is on the right
pathway but says “There is still much work to be done but the
future for Mexico and Aquaculture is very promising.”
