Fisheries and aquaculture are receiving increasing attention, not only because they represent an important source of livelihoods and food, but also because of our increasing understanding of aquatic ecosystems.
Many fish stocks are currently overexploited, and the international nature of the resources makes them difficult to manage. Is the current food supply in danger?
Evolution of fisheries sector in BangladeshMD. ZANE ALAM
Bangladesh is a densely populated country of 147 570 km2 with a population of 160
million people. It is fortunate in having an extensive water resource in the form of ponds,
natural depressions (haors and beels ), lakes, canals, rivers and estuaries covering an area
of 47,03,658 ha .
The present per capita annual fish consumption in Bangladesh stands at about 14 kg/year
against a recommended minimum requirement of 18 kg/year; hence, there is still need to
improve fish consumption in the country.
Fisheries in Bangladesh are diverse, there are about 795 native species of fish and shrimp
in the fresh and marine waters of Bangladesh and 12 exotic species that have been
introduced. In addition, there are 10 species of pearl bearing bivalves, 12 species of
edible tortoise and turtle, 15 species of crab and 3 species of lobster.
Tuberculosis (TB) is an infectious disease that affects a growing number of people around the world. Usually, it can be treated with antibiotics but some forms of the disease have emerged that do not respond to different types of drugs, making it very difficult to treat, especially in people already infected with HIV.

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.
Aquaculture takes centre stage at MONACO BLUE INITIATIVE 2015 6TH EDITIONInternational Aquafeed
The last edition of the Monaco Blue Initiative (MBI) in Chile in 2014 questioned the status and feedback from aquaculture in America, towards a sustainable approach to its development.
Ocean overfishing is simply the taking of wildlife from the sea at rates too high for fished species to replace themselves. The earliest overfishing occurred in the early 1800s when humans, seeking blubber for lamp oil, decimated the whale population. Some fish that we eat, including Atlantic cod and herring and California's sardines, were also harvested to the brink of extinction by the mid-1900s.
"Why bother about the sustainability of the world's OCEANS" is first in the series of environmental sustainability presentations of WOW Bali International Initiative. This is a continuing documentation of learning resources about global efforts and initiatives aimed at reviving the world's ocean environment and marine and coastal ecosystems. Ultimately, this will show how the earth's oceans are interconnected to human survival and sustainable development.

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.

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.
The first stage in the aquaculture production chain is the hatchery. This is where the breeding of fish, hatch
Catch Per Unit Effort (CPUE) of Bivalves in Northwestern Bohol, PhilippinesAI Publications
Catch Per Unit Effort (CPUE) is a measure of status of marine resource in a given area. In this study, bivalve fishery information was gathered using the self-structured questionnaire. There were 61 respondents who were the registered fishermen of Calape, Tubigon and Clarin. Among the three towns it was Clarin where highest mean CPUE was observed with 1.2kg/hr/man. This was followed by Calape with 0.8kg/hr/man and lowest mean CPUE was recorded in Tubigon with 0.6kg/hr/man. High CPUE value means that there are still enough bivalve resources in the area and lowest CPUE means that these resources are endangered. Considering that, the result of this study showed that there is a need to regulate the collection of bivalves with lower wild stocks to avoid loss of these natural resources.
Investment Guideline for Sustainable Aquaculture in IndonesiaTrini Pratiwi
Access to finance in the aquaculture sector has
traditionally been a hotly debated topic. On one side,
there is recognition that aquaculture is needed to
satisfy the growing demand for quality animal proteins.
On the other, the risks associated with aquaculture
production and the fragmentation of the sector –
especially in tropical aquaculture – have limited the
appetite for investors to finance the sector, other than
services and processing.
This document is designed for investors operating
in Indonesia. It aims to provide a summary of the
aquaculture sector and its potential, a description of
the risks and mitigation strategies, and a presentation
of possible financial models.
The document is unique in that it can be used by
private-sector players along related aquaculture supply
chains as well as financial institutions and donors. YIDH
intends the document to make a starting point for
various stakeholders and regulators to support better
investment in sustainable aquaculture, and to open
the discussion on new ideas and opportunities in the
future.

The Roman Empire A Historical Colossus.pdfkaushalkr1407
The Roman Empire, a vast and enduring power, stands as one of history's most remarkable civilizations, leaving an indelible imprint on the world. It emerged from the Roman Republic, transitioning into an imperial powerhouse under the leadership of Augustus Caesar in 27 BCE. This transformation marked the beginning of an era defined by unprecedented territorial expansion, architectural marvels, and profound cultural influence.
The empire's roots lie in the city of Rome, founded, according to legend, by Romulus in 753 BCE. Over centuries, Rome evolved from a small settlement to a formidable republic, characterized by a complex political system with elected officials and checks on power. However, internal strife, class conflicts, and military ambitions paved the way for the end of the Republic. Julius Caesar’s dictatorship and subsequent assassination in 44 BCE created a power vacuum, leading to a civil war. Octavian, later Augustus, emerged victorious, heralding the Roman Empire’s birth.
Under Augustus, the empire experienced the Pax Romana, a 200-year period of relative peace and stability. Augustus reformed the military, established efficient administrative systems, and initiated grand construction projects. The empire's borders expanded, encompassing territories from Britain to Egypt and from Spain to the Euphrates. Roman legions, renowned for their discipline and engineering prowess, secured and maintained these vast territories, building roads, fortifications, and cities that facilitated control and integration.
The Roman Empire’s society was hierarchical, with a rigid class system. At the top were the patricians, wealthy elites who held significant political power. Below them were the plebeians, free citizens with limited political influence, and the vast numbers of slaves who formed the backbone of the economy. The family unit was central, governed by the paterfamilias, the male head who held absolute authority.
Culturally, the Romans were eclectic, absorbing and adapting elements from the civilizations they encountered, particularly the Greeks. Roman art, literature, and philosophy reflected this synthesis, creating a rich cultural tapestry. Latin, the Roman language, became the lingua franca of the Western world, influencing numerous modern languages.
Roman architecture and engineering achievements were monumental. They perfected the arch, vault, and dome, constructing enduring structures like the Colosseum, Pantheon, and aqueducts. These engineering marvels not only showcased Roman ingenuity but also served practical purposes, from public entertainment to water supply.
A Strategic Approach: GenAI in EducationPeter Windle
Artificial Intelligence (AI) technologies such as Generative AI, Image Generators and Large Language Models have had a dramatic impact on teaching, learning and assessment over the past 18 months. The most immediate threat AI posed was to Academic Integrity with Higher Education Institutes (HEIs) focusing their efforts on combating the use of GenAI in assessment. Guidelines were developed for staff and students, policies put in place too. Innovative educators have forged paths in the use of Generative AI for teaching, learning and assessments leading to pockets of transformation springing up across HEIs, often with little or no top-down guidance, support or direction.
This Gasta posits a strategic approach to integrating AI into HEIs to prepare staff, students and the curriculum for an evolving world and workplace. We will highlight the advantages of working with these technologies beyond the realm of teaching, learning and assessment by considering prompt engineering skills, industry impact, curriculum changes, and the need for staff upskilling. In contrast, not engaging strategically with Generative AI poses risks, including falling behind peers, missed opportunities and failing to ensure our graduates remain employable. The rapid evolution of AI technologies necessitates a proactive and strategic approach if we are to remain relevant.
