Krishna presented on the topic of aquaculture and its role in rural development. Some key points include: (1) Aquaculture is the fastest growing food sector and produced over 90 million tonnes globally in 2012, helping to meet the world's increasing demand for protein; (2) Aquaculture plays an important role in rural development by generating employment, utilizing waste, developing infrastructure, and empowering small farmers; (3) Aquaculture also improves nutrition and food security by providing affordable protein to poor communities through small backyard ponds and fish farming.
Mosquito fish are very small freshwater fish native to the United States that eat mosquito larvae. They have a greenish sheen, upturned mouth, and flattened head. Mosquito fish were introduced worldwide as a bio-control for mosquito populations in over 70 countries. They can tolerate wide temperature ranges and survive in inhospitable environments with low oxygen or high salt concentrations. Females give birth to live young without laying eggs and can produce new broods every six weeks.
Reproduction is a fundamental biological process which enables continuation of species. In fisheries biology, reproduction assumes greater significance to understand sexual
dimorphism, process of maturation, size or age of maturity, breeding season, spawning area, sexual segregation, migration, fecundity, embryonic and larval development and
recruitment. Most of the management strategies in capture fisheries are based on reference points that are the manifestations of reproductive biology. In aquaculture,
knowledge of reproductive biology of a fish is essential for hatchery production of fish feeds.

This document discusses pigmentation and color change in fish. It explains that coloration in fish is due to chromatophores containing pigments like carotenoids, melanin, purines, and flavins. Some fish can change color through the aggregation or dispersion of pigment granules in chromatophores. This color change is controlled through both hormones and nerves. Hormones like MSH and adrenaline cause pigment dispersion or aggregation, while stimulation or cutting of nerves innervating chromatophores also leads to color changes. Both hormonal and neural pathways interact to regulate color adaptation in different fish species.

17 - Cryopreservation of fish gametes.pptxPiyushBehera3
Cryopreservation, or freezing biological material at ultra-low temperatures, has several applications in fisheries and aquaculture. It allows for the wider distribution of gametes, reduces the number of broodfish needed, and facilitates selective breeding programs. The spermatozoa of many fish species can be cryopreserved due to their small size, large numbers, and simple membrane structure. Prior to freezing, spermatozoa are collected, tested for motility, diluted with an extender solution, and mixed with a cryoprotectant to minimize freeze damage. Samples are then cooled at a controlled rate, frozen in liquid nitrogen for storage, and later thawed at a controlled rate to test viability. While eggs and

Mechanism of Hilsa (Tenualosa ilisha) Migration and its Impact to Nature
Tenualosa ilisha (ilish, hilsa, hilsa herring or hilsa shad) is a species of fish in the herring family (Clupeidae), and a popular food fish in South Asia. Five type of ilish can be found worldwide. Yearly ilish caught are 5,000,000 ton. Among them, 50%-60% are caught by Bangladesh, 15%-20% are caught by India, Pakistan and rest 5%-10% are caught by Malaysia, Thailand, China, Vietnam and Sri Lanka. The fish contributes about 12% of the total fish production and about 1% of GDP in Bangladesh.
Bundhs are tanks or impoundments that simulate riverine conditions for carp breeding during monsoon months. Dry bundhs are seasonal while wet bundhs are perennial. Dry bundhs, popular in West Bengal and Madhya Pradesh, consist of storage ponds, hatcheries, and sluice gates for draining water to allow multiple spawnings per season. Wet bundhs in West Bengal are larger ponds that fill with monsoon rainfall, providing a single annual spawning opportunity. Both bundh types provide controlled environments to induce carp breeding through water level manipulation.
Fisheries and aquatic resources are economically, ecologically, culturally and aesthetically important to the nation. From the global perspectives, the main issues facing by the international fishing community generally are over fishing, overcapacity, by-catch management as well as environmental degradation. The combined effect of these factors that have made 60-70% of the major world fisheries resources are in urgent need of management action to restrict the increase in fishing capacity and to rehabilitate damaged resources (FAO,1991). In Bangladesh, fisheries is one of the major subsectors of agriculture, which play a dominant role in nutrition, employment, earning foreign currency and other areas of economy. Many of our open waterbody are polluted with various pollutants and harmful chemicals. Water Resources Planning Organization (WARPO) has prepared the National Water Management Plan (NWMP) for Bangladesh in December 2001. The goal of the NWMP is to implement the National Water Policy (NWPo) and contribute to national economic development through rational management of open water resources, in a way that protects the natural environment and improves the quality of life for the people of Bangladesh. Open water fisheries are major aquatic common property resources in Bangladesh covering over four million hectares. Around ten percent of the population of 120 million depend for their livelihoods on fisheries.
Biofloc fish farming for sustainable aquacultureOrganicaBiotech1
Biofloc technology is an emerging, eco-friendly and cost-effective approach for sustainable fish farming. Earlier, the biofloc system was used as the means to treat wastewater and control fish production.
Transport of hatchlings, fry, and fingerlings is common in aquaculture. Proper techniques involve understanding fish physiology and mortality causes during transport. Seed can be collected from wild or hatcheries. Major carps are collected from flooded rivers during monsoon season. Seed from estuaries and coastal waters include milkfish, mullets, pearlspot, and seabass. Bundhs are seasonal flooded areas that stimulate breeding. Induced spawning techniques breed species that don't spawn in captivity using hormones. Transport uses open or closed oxygenated systems. Factors causing mortality are oxygen depletion, waste accumulation, temperature fluctuations, and stress. Anaesthetics and antibiotics are used to reduce stress and prevent disease.

Ninety red tilapias with an initial weight of 7.32 ± 1.31 g were acclimatized and randomly introduced into 9 aquaria in 3 groups with 10 fish per aquarium. Different levels of PWC 0 T0 , 1 T1 , and 2 T2 were incorporated in the diets of red tilapia for four weeks. After the experiment, average body weight ABW , specific growth rate SGR , relative growth rate RGR weight gain WG , feed conversion ratio FCR and survival rate SR of the experimental fish were computed. No significant differences were observed on feed utilization, survival, and waste excretion of the fish. Furthermore, ABW and WG of the experimental fish did not show any significant difference, however, significantly higher P 0.05 SGR and RGR were observed from T1 compared to the other treatments. Consequently, this study showed that supplementation of 1 PWC in the diet is the most suitable in improving the growth performance of red tilapia. Jaypee. S.

Forage fish such as herring, smelt and anchovy play a key role in marine ecosystems. They transfer energy from plankton to larger fish, seabirds and mammals. Forage fish populations in Washington state have declined significantly over the past few decades due to overfishing, habitat loss and pollution. State agencies monitor forage fish populations through surveys of spawning beaches and trawl studies. Tagging studies of surf smelt show they can be marked without harm and recaptured, providing insights into their movements and spawning behaviors over multiple seasons. Continued monitoring is needed to understand threats to these important species and the ecosystems that depend on them.
The document discusses various methods used to study ecosystems, including quadrats, light and moisture meters, and pitfall traps. It provides examples of results from using these methods, such as counts of different plant species within quadrats. Energy flows through ecosystems from producers to consumers in a non-linear way, with about 10% of energy being transferred between trophic levels as most is lost through heat and waste. Food chains and webs show the transfer of energy and matter between organisms in an ecosystem.
The document summarizes key concepts about ecosystems and the biosphere. It discusses components of ecosystems like abiotic and biotic factors. It also describes methods for measuring environmental factors and populations within ecosystems. Food webs, energy flow, and limiting factors that control population growth are examined. The roles of producers, consumers, and decomposers are defined. The document also touches on pollution sources, their impacts on biodiversity, and indicator species used to monitor environmental quality.
Dunn, Heidi, Ecological Specialists, Inc., Freshwater Mussels and the New Amm...Kevin Perry
Freshwater mussels are an important part of river ecosystems but many species are endangered. Mussels play key roles like filtering water and providing habitat. They are very sensitive to pollutants like ammonia and were among the most sensitive species considered in setting the 2013 US EPA ammonia standard. This standard will better protect mussels and other aquatic life in Missouri waters, though it may apply broadly across the state given mussels' widespread historical distribution. Cooperation will be important to successfully implement the new protective standard.
The document discusses the life cycle of milkfish from broodstock to larvae and provides information on milkfish farming in the Philippines. It outlines best practices for stocking procedures, including acclimatization and proper release of fry.

The Growth of Oreochromis niloticus (2.6g initial average size) was studied in 100m2 earthen ponds for 180 days under tropical field environment. Varying fertilizing regimes consisting of Pennisetum purpureum (PP) and Musa sapientum (MS), two locally available weedy grasses were applied in duplicates in the experimental ponds, at the rate of 0.1-0.2 kg dry matter per m2 per day. Water quality parameters were monitored bimonthly between 8:00am-9:00am . Final average fish weight varied significantly (p<0.05) as follows: 43.85g, 35.5g, 59.5g, 24.9g and 50g, 2 respectively for PP, MS, MS+PP, T0 and T1. Corresponding daily growth were 2.2g/d, 0.1g/d, 0.3g/d, 0.1g/d and 0.2g/d. Survival rate equally varied significantly as follow: 60 %, 67 %, and 98 %, 70 % and 97 % respectively. During the study period, the results indicated the water quality were permissibole limits and can be used for livestock of Oreochromis niloticus .
Freshwater aquaculture production has grown significantly worldwide in recent decades. The document discusses the definition and origins of aquaculture, noting that it originated much later than agriculture due to difficulties in appreciating aquatic environmental parameters. It provides statistics on global aquaculture production in 2009, with China as the top producer. The majority of production occurs in freshwater environments. Carps make up the largest portion by volume. India has considerable freshwater resources and biodiversity of cultured fish species, with carp culture being the main focus.
This document discusses the importance of sharks for life on Earth. It explains that sharks help maintain the balance of ocean ecosystems by preying on smaller fish that eat phytoplankton and algae. This allows phytoplankton and algae to thrive, which produce oxygen and absorb carbon dioxide through photosynthesis, regulating the carbon cycle that supports all life on Earth. The loss of sharks has caused populations of smaller fish to increase, threatening phytoplankton, algae, and coral reefs, which provide habitat for many ocean species.
1) Tilapia were introduced to Iraq in 2011 from Syrian farms, spreading to waterways and causing problems competing with native fish. They are used for biological control by eating mosquitoes that transmit malaria.
2) Tilapia are freshwater fish native to Africa that have been introduced worldwide for aquaculture. They have high growth rates, adaptability, and ability to breed in captivity.
3) The document discusses tilapia taxonomy, environmental requirements, nutritional needs at different life stages, feeding rates, reproduction as mouth-brooding fish, and their suitability for aquaculture.
Coastal ecosystems like coral reefs have high productivity and biodiversity due to dynamic spatial gradients in factors like salinity, temperature, light, and nutrients. Coral reefs specifically proliferate in warm, shallow, saline waters. Corals are colonial animals whose polyps secrete calcium carbonate to form hard structures over time. Corals have a symbiotic relationship with algae called zooxanthellae, which provide nutrients through photosynthesis. Corals reproduce both asexually through fragmentation and sexually through broadcast spawning or brooding.
The document discusses biotic and abiotic factors that can impact populations within an ecosystem. Biotic factors are the living components like predators, food supply, disease, population density, birth rate and mortality. Abiotic factors are physical and chemical non-living factors like wind, temperature, water, light and soil. The document also notes that biodiversity is at risk with an estimated 1-10 million species that are yet to be discovered, and species are disappearing at an alarming rate due to habitat destruction, hunting, invasive species and other reasons. Methods to save biodiversity include protecting individual species in zoos/parks and through breeding programs, as well as taking an ecosystem approach to protect entire habitats.
This document provides information about microbes and their role in coral reef ecosystems. It begins by discussing the size of microbes and introduces zooxanthellae, a type of symbiotic dinoflagellate microbe that lives inside coral polyps. Zooxanthellae perform photosynthesis, providing energy to the coral and allowing coral reefs to flourish in nutrient-poor tropical waters. However, environmental stress like rising water temperatures can cause coral bleaching where the zooxanthellae are expelled, leaving the coral vulnerable. The document then discusses several diseases affecting corals like black-band disease and white-band disease caused by microorganisms.

Assessment of nutritive values of some waterweedsAlexander Decker
This document summarizes a study that evaluated the nutritive values and phytochemical constituents of 10 common waterweeds in Nigeria. The study found that the waterweeds contained 13.67-32.67% crude protein, 4-26% crude fiber, and 7.33-26% ash. The waterweeds also had adequate levels of other nutrients. Though high in moisture, the waterweeds could provide a source of nutrients, especially protein, for livestock during dry seasons. Qualitative analysis found that most waterweeds contained steroids, while four contained saponins and some contained phenols or tannins. Nymphaea lotus was found to have the lowest levels of anti-
The document discusses algal blooms in water sources in Malaysia from 1976 to 2015. It describes how algal blooms occur naturally but have increased due to cultural eutrophication from human activities that introduce excess nutrients. The key human causes contributing to cultural eutrophication and algal blooms are agricultural runoff of fertilizers, domestic sewage, and industrial discharge, which introduce phosphorus and nitrogen into water bodies. If left uncontrolled, cultural eutrophication can significantly degrade water quality and ecosystems. Case studies on the Malacca Straits and Tasik Sri Serdang lake found high risks of cultural eutrophication and algal blooms from nutrient pollution of stagnant water bodies near heavy human

The Cumbrian Lakes Research Forum 2018 was a one-day workshop held at Lancaster Environment Centre on October 9, 2018. The purpose was to highlight current lake research that could help inform evidence-based management of the lakes. The day included nine 10-minute talks on topics such as long-term trends in the upland waters monitoring network, climate change impacts on lakes, and catchment restoration projects. Group discussions focused on developing ideas for educational films about freshwater conservation.
The Welland Sea Trout Project aims to restore the sea trout run between the Wash, Stamford, and the River Gwash via the Maxey Cut flood relief channel. The project has removed barriers to fish movement, managed and enhanced habitat, and tackled water quality and quantity issues. Monitoring indicates the sea trout run has been restored, as stable isotope analysis of trout scales has shown some trout have spent time in salt water. Future projects continue work on the Maxey Cut and River Gwash to further improve habitat and fish passage.
The document discusses the Environment Agency's policies for stocking trout, grayling, and coarse fish. The main difference between policies for coarse fish versus salmonids is that trout populations evolved in isolation after the last ice age and developed unique genetic traits, while coarse fish evolved into distinct species. Stocking farmed trout risks losing their survival traits, so policies allow only sterile triploid trout. In contrast, coarse fish like bream and dace sorted into species with different habitat preferences, so fertile fish can be stocked. Grayling policies also aim to maintain distinct river basin strains. Stocking is one fishery management tool used to ensure sustainable fisheries now and in the future.
Tree Works: Lessons Learned discusses outcomes from a workshop about tree works carried out along the River Aire.

CAKE: Sharing Slices of Confidential Data on BlockchainClaudio Di Ciccio
Presented at the CAiSE 2024 Forum, Intelligent Information Systems, June 6th, Limassol, Cyprus.
Synopsis: Cooperative information systems typically involve various entities in a collaborative process within a distributed environment. Blockchain technology offers a mechanism for automating such processes, even when only partial trust exists among participants. The data stored on the blockchain is replicated across all nodes in the network, ensuring accessibility to all participants. While this aspect facilitates traceability, integrity, and persistence, it poses challenges for adopting public blockchains in enterprise settings due to confidentiality issues. In this paper, we present a software tool named Control Access via Key Encryption (CAKE), designed to ensure data confidentiality in scenarios involving public blockchains. After outlining its core components and functionalities, we showcase the application of CAKE in the context of a real-world cyber-security project within the logistics domain.

20. Image analysis
• Zooplankton samples scanned
and images processed to
estimate individual biovolume.
• Each “target” categorised as
Daphnia or copepods.
• Average size structure
analysed over time.
22. Summary
• Predation pressure (from fish) has increased dramatically 1991-2010.
• The zooplankton community has undergone a significant change: calanoid
copepods vs. other species.
• Only in the case of Eudiaptomus, is it likely that fish predation has caused an
observed decline in abundance.
• Complementary size-structure analysis does not strongly support the predation
hypothesis (for the community as a whole).
• Predation effect has likely been “selective”; acting on only some taxa.

Editor's Notes
You have already heard about the potential expansion of roach populations within the UK. This presentation is about the link between the expanding Windermere roach population and potential impacts upon the zooplankton community. Put simply, do we see a top-down effect of increasing fish predation upon zooplankton in the lake?
Why should we care about the zooplankton? the occupy an important middle-position in the aquatic foodweb; feeding on algae and being fed upon by fish. They are a conduit for the flow of energy and carbon through the aquatic food web. zooplankton can impact upon water quality, by consuming algae, and represent an important food resource for many fish species, especially early in their development.
the community of Windermere is relatively simple. It is dominated by two Cladocera, two calanoid copepods and two cyclopoid copepods. there are a number of other species that occur, but they tend to be rather less abundant. in this talk, I’m going to focus on three species that are especially dominant within the community.
as you have seen, hydroacoustic data show that there has been a dramatic increase in fish abundance within Windermere over the last approx. 20 years. complementary netting data shows that the only species showing a significant increase in abundance over this time period is the roach. we therefore believe that it is the increasing roach population bringing about this increase in the hydroacoustic record. So...this would suggest a large increase in fish predation for the native zooplankton community.
what would we expect to happen to the zooplankton community under these conditions?
What would we expect to happen to the zooplankton community under these conditions? Firstly we would expect that, with higher levels of predation, zooplankton abundance would decrease.
in order to test this expectation we used long-term monitoring data collected fortnightly on the lake. Specifically, for this work, we used records of water temperature and zooplankton community structure, assessed from net haul samples collected at the deepest point of the lake. all data were gathered from the North Basin of the lake in order to assess predation pressure, we used hydroacoustic data (collected monthly). These data were collected along a series of transects spanning the North Basin. This gave us an assessment of whole-water column abundance of fish between 2 and 20 cm in length.
in order to assess predation pressure we used the hydroacoustic abundance records, and assessments of individual fish size, in conjunction with water temperature, to estimate the maximum consumption rate of the fish population. we did this using a published bioenergetics model parameterised for roach, as we believe that it is this species that is largely responsible for the observed fish abundance increase.
so the key is question is whether or not zooplankton population have declined as a result of the observed increase in predation. we have observed an increase in fish predation over the 20 year period (here log-scaled) at the same time, we may observe a decline in zooplankton abundance (here for Eudiaptomus) the most straightforward approach would appear to be correlating one against the other, as we have done here. however, with observed data we always have the issue of correlation vs. causation: the zooplankton decline and fish predation may be correlated, but this may only be because they share a long-term trend. Those long term trends could, in principle, be driven by other unmeasured factors. so we may have an apparent, though not real, causal relationship.
though we can never be 100% certain of assigning causality from field data, we would be more confident in the observed relationship if there was still a relationship between predation and zooplankton abundance, even after removing long-term trends from the data. This would mean that shorter term variations are also related.
so, we see that our zooplanktivory index increases markedly over time, as do the fish numbers from the hydroacoustic record. We see that this increase is statistically very highly significant, and the curve represents a smooth trend fitted through the data. I have had to log-transform data in order to ensure that results are not heavily biased by small numbers of exceptional observations.
so what changes have we seen for our focal zooplankton species? in the case of Daphnia, which is most abundant in the spring period, we don’t see a long-term decline in abundance, though we do see rather a lot of interannual variation in abundance.
the same is also true of the summer-peaking copepod Cyclops. again, much interannual variation, but little evidence of a long term trend.
However, for the calanoid copepod Eudiaptomus, the story is different. Typically, Eudiaptomus produces two generations per year. The autumn/winter cohort is always the strongest of the two. We see that the abundance of Eudiaptomus has declined throughout the study period. So different species have been showing different patterns of change.
are these changes correlated with changes in predation? In the case of Daphnia, no. For Cyclops we have a positive correlation between abundance and predation, which runs counter to expectations. For Eudiaptomus, we have the expected strong negative correlation.
however, only in the case of Eudiaptomus is the relationship still significant after removing shared long-term trends.
a second expectation that we would have, if fish predation was having a strong impact on the community as a whole,....
a second expectation that we would have, if fish predation was having a strong impact on the community as a whole,.... Would be that large species and individuals would be lost most severely. this is because fish are visual predators and can more effectively locate larger, more conspicuous, prey.
we tested this expectation by scanning zooplankton from our samples, and using image analysis techniques to categorise individual zooplankton into broad taxonomic groups, and measure individual body size.
the technique can effectively discriminate between Daphnia and copepods. we have data from selected years throughout the time series and the gaps for Daphnia indicate when too few animals were analysed to give a reliable estimate. these results are hot off the press, and need further detailed analysis, but at this stage they do not seem to show evidence for the expected decline in zooplankton body size over time, as fish predation has increased.
In summary: we have certainly seen a dramatic increase in predation pressure in the lake, and we have seen changes in the zooplankton community. Specifically, calanoid copepods have become less abundant over time, whereas other groups have not shown the same trend. however, only in the case of Eudiaptomus does it seem likely that there is a link between increasing fish predation and zooplankton decline. furthermore, size structure analysis does not as yet support the idea of increased predation have a strong effect on the whole zooplankton community. so it looks like predation effects might have impacted some species rather than others.
however, we must note some caveats with the approach. we know that larval fish are not well resolved in these hydroacoustic data, due to the sensitivity of the system used early in the acoustic monitoring programme. In recent years we have better estimates of larvae. so, larvae born in spring-early summer will be poorly detected, until the grow large enough to be detected in late summer and autumn. we have a better assessment of fish predation at this time of year. so, an open question for future research is now early-stage roach have impacted the lake community. The other open question is over the other factors that are affecting zooplankton populations in the lake. In this project we were able to process a great number of archived samples and we are now able, for the first time, to examine multiple drivers acting on individual species and how these changes may in turn affect water quality.
