Abstract:

A global need for increased and sustainable healthy food production together with a global decline in fishery stimulate dynamic development of aquaculture. However, in many situations this development negatively impacts water quality in lakes, reservoirs, rivers and even some coastal waters. rnEcohydrology provides a holistic framework for understanding and management of hydrological cycle and biological processes at catchment scale. It allows not only for elimination of environmental risks generated by aquaculture but also amplification of opportunities by identification of optimal areas for its development in a river basin. Following the Ecohydrology theory, in-depth understanding of water-biota interplay creates a background for development of efficient ecosystem biotechnologies and cost-effective system solutions for mitigation of negative impacts of aquaculture. This in turn will creates opportunities for further sustainable development of aquaculture.rnEcohydrology as an integrative environmental science provides opprtunity for upgrading the five sustainability dimensions which are: water resources, biodiversity, ecosystem services, resilience and cultural heritage (WBRSC) and thus, the sustainable management framework for aquaculture. Simultaneous consideration of all the five elements realised with the use of ecohydrological biotechnologies will provide an important stimulus in creating the sustainable future we want.

Keynote: US FDA regulatory approach to veterinary drugs used in aquaculture

Time : 10:30-11:00

OMICS International Aquaculture Summit 2016 International Conference Keynote Speaker Barbara Montwill photo
Biography:

Barbara Montwill is the expert on FDA regulatory policy with regards to food safety of aquaculture products. She received her M.Sc. in marine biology from the University of Gdansk in Poland. Her professional career started at the Institute of Oceanology, Polish Academy of Science, where she conducted studies of the marine ecosystem in an area of environmental biology, ecotoxicology, and biogeochemical cycles. Her work at USFDA involves the formulation of polices and guidance on issues pertaining to aquaculture, particularly chemical contaminants and animal drug residues in seafood. She is engaged in the evaluation and audits of aquaculture food safety programs. She is also provides training to aquaculture community. She participates in works of international and professional organizations (FAO COFI, Codex, and ISO) providing technical input on the subject of seafood safety.

Abstract:

Seafood is the most important food commodity consumed globally, accounting for nearly 20% of animal source food. It is forecasted that the world’s population will require 232 million metric tons (MT) seafood by 2030, around 62 million MT more than the planet can expect to produce. rnThe aquaculture production is expected to continue its growth contributing significantly to the global seafood trade and providing around 109 million MT while wild fisheries will stay stable with production of 61 million MT. However, achieving a higher aquaculture production level to meet the future raising global demands cannot compromise seafood safety and quality. The aquaculture expansion, associated with increasing intensification and diversification, might require the use of veterinary medicines to prevent and treat disease outbreaks, assure healthy stocks and maximize production. rnIt is essential to protect animal health and ensure good animal welfare through the prevention, control and treatment of conditions that cause animal suffering. The use of appropriate antimicrobial treatments is one of the effective management responses to emergencies linked to infectious epizootics. But, routine or systemic use of drugs to compensate for poor hygienic conditions or management practices can lead to problems related to increased frequency of bacterial resistance and the potential transfer of resistance genes from the aquatic environment to other bacteria. Furthermore, imprudent use of antimicrobials may also result in the occurrence of their residues in aquaculture products and, as a consequence, bans of those products by importing countries and economic losses. The judicious and responsible use of veterinary medicines is an essential component of successful commercial aquaculture production systems.rnThis presentation will introduce the audience to the regulatory structure in the United States that applies to use of animal drugs in aquaculture.rn

Keynote: Isotopic analysis to improve fisheries management and aquaculture operations

Time : 11:15-11:45

OMICS International Aquaculture Summit 2016 International Conference Keynote Speaker Debashish Mazumder photo
Biography:

Debashish Mazumder is a Senior Research Scientist in the Australian Nuclear Science and Technology Organisation (ANSTO) with more than 20 years of experience in aquaculture and aquatic ecology. He also holds adjunct academic positions at the University of New South Wales (UNSW), Macquarie University (both within Australia) and Beijing Forestry University, China. His area of expertise includes using nuclear and isotopic techniques to quantify the impacts of water management, land use and climate variability on the structure and function of aquatic ecosystems and to maximise the benefit of aquaculture operations. From 1990 to 1999, he worked with the WorldFish Centre to improve the production and management of aquaculture in Bangladesh. Since 2006, he has been collaborating with universities and government agencies in Australia, PNG, Malaysia and China on various environmental and aquaculture projects. He is an Associate Editor of WETLANDS, and published a significant number of peer reviewed journal papers and scholarly book chapters on stable isotopes.

Abstract:

Water is a vital resource that is under ever increasing demand from population, industry growth, agricultural development and environmental allocations that are crucial to sustain the natural ecosystems upon which we all rely. Understanding source, fate of energy and nutrients in aquatic ecosystems is fundamental for the sustainable management of fisheries and aquaculture operations. I will present findings from my collaborative works with multiple government agencies and universities where nuclear and isotopic techniques have been used in freshwater and marine environments including aquaculture to solve problems that challenges the sustainability of these resources. Stable carbon and nitrogen isotopic techniques helped identify nutrient sources for fish in rivers, wetlands and estuaries. It also helps determine how nutrient sources change as a result of anthropogenic and climatic conditions, which is important when making management decisions. Isotopic work in a temperate river in Australia identified how the niche diversity of fish was constrained due to habitat modification and discontinuity in river connectivity. Isotopic application in coral habitats identified the functional role of coral and their links with other species in marine environments. The isotopic applications in oyster larvae production in the hatchery in New South Wales, Australia and inland finfish aquaculture at PNG suggest operational costs can be reduced by carefully utilising production inputs, or changing the ingredients used in feed formulations. These results provide insight for further applications of isotopic and nuclear techniques to determine whether management practices affect the valuable nutritional quality of fish.

Abstract:

Aquaculture is ingrained in Bangladesh culture, as reflected in extensive public and commercial culture and favorable patterns of governance. Farmed fish contribute substantially to the customary diet, recently favoring increasing proportions of farmed vs. wild-captured fishes. National aquaculture productivity has increased steadily, resulting in a move upward in international rankings; FAO statistic recently showed Bangladesh as the #5 ranked farmed fish prodcuer, accounting for 2.6 % of global production. rnSteadily increasing fish yields have been supported by continuous cultural and technological developments. Integrated culture operations, family household aquaculture involving women and children, and management of previously unused areas have contributed to growth in production. Booming shrimp and prawn culture is transitioning to reliance on hatchery-based operations using PCR screening for pathogen management. Genetic selection programs have produced improved strains of Nile tilapia (e.g. the GIFT strain), and similar efforts are underway for Rohu and other carp species. Marine aquaculture remains underdeveloped, and is a likely focus of ongoing efforts to meet growning demands for human nutrition. Increased population and urbanization as forecast suggest that sustained aquaculture development will be critically important.rnFishes cultured in fresh water have generally poorer nutritional profiles than wild-caught marine fishes, and nutritionally-based aquaculture is under development. The mola (Amblypharyngodon mola) and other small indigenous species (SIS) are eaten whole, thereby making excellent contributions of protein, desirable minerals, vitamins, and essential fatty acids. These fishes figure importantly in addressing nutritional deficiencies, and patterns of increasing culture and consumption of SIS in Bangladesh are likely to continue.rn

Biography:

I have been working as a Senior Research Fellow (Senior Associate professor position) in Universiti Putra Malaysia (UPM) since 2010, and have been involved in teaching/supervising undergraduate and postgraduate students in various fields of marine sciences, fisheries and aquaculture as well as conducting research on “Biology, ecology, diversity, breeding, seed production, culture and biochemical composition of sea urchins, sea cucumbers and fishes”. Meanwhile, I am involved in some international collaborative research work on marine biology, fisheries and aquaculture with scientists of different institutes, including Smithsonian Institution (USA), Australian Nuclear Science and Technology Organization (Australia), Sultan Qaboos University (Oman), Kindai University, Japan, Sinop University (Turkey) etc., while others are under the process of establishment. Before that I had obtained my M.S. and Ph.D. degrees in Marine and Environmental Sciences from University of the Ryukyus, Okinawa, Japan (1995-2001), where I also did two years (2003-2005) JSPS postdoctoral research on “marine biology, reproduction, fertilization, hybridization, speciation and aquaculture in the Indo-Pacific sea urchins”. I also worked in the Smithsonian Tropical Research Institute, Panama, and USA for two years (2007-2009) in the same field with Atlantic sea urchins as the Smithsonian postdoctoral researcher. In addition, I worked as a Chief Researcher in the Ocean Critters Ranch, Inc., Crowley, Texas, USA on “breeding and propagation of various marine ornamental fishes and corals”. Moreover, I worked as a senior scientist in Bangladesh Fisheries Research Institute during 1988 to 2007 in various fields of Breeding Biology, Nursing, Aquaculture and Fisheries Management. My expertise areas broadly lie in Marine and Freshwater Biology, Limnology and Aquatic Ecology, Reproductive Biology and Fertilization kinetics, Population dynamics, Breeding, Nursing and Seed Production, Aquaculture and Conservation, and Taxonomy and Evolution. My multidisciplinary research and educational backgrounds provide me a unique and novel perspective in conducting research work in a diverse field of Aquatic Biology and Ecology, Marine and Environmental sciences, Fish Nutrition, Aquaculture and Fisheries Sciences, and Biodiversity conservation, and thus enable me to coordinate with scholars in different academic disciplines. Besides, I have work experiences in organizing/conducting training courses, workshops, grant writings, academic seminars and so forth. I am committed to working with my students and maintaining professional relationship with many of them years beyond the classroom. Through my research works, I have published 110 scientific papers in international and nationally reputed high impact journals. I have written 2 books and 12 book chapters. A good number of scientific papers have also been presented and published in international conferences, symposia and workshops. I have also been serving as editors and editorial board members of some reputed journals and proceedings.

Abstract:

Echinoids or sea urchins (Echinodermata: Echinoidea) constitute a group of exclusively marine invertebrates inhabiting the intertidal down to the deep-sea trenches around the world. The gonad of sea urchin, usually referred to as "Sea urchin Roe”, is culinary delicacies in many parts of the world. The roe of sea urchins is considered as a prized delicacy in Asian, Mediterranean and Western Hemisphere countries and have long been using as luxury foods in Japan. Japanese demand for sea urchins raised concerns about overfishing, thus making it one of the most valuable sea foods in the world. The population of the Asian Pacific Region has been using it for long time as a remedy for improving general living tone and treatment for a number of diseases. Gonads of Sea urchin are also rich in valuable bioactive compounds, such as polyunsaturated fatty acids (PUFAs) and β-carotene. PUFAs, especially eicosapentaenoic acid (EPA, C20:5) (n-3)) and docosahexaenoic acid (DHA C22:6 (n-3)), have significant preventive effects on arrhythmia, cardiovascular diseases and cancer. β-Carotene and some xanthophylls have strong pro-vitamin A activity and can be used to prevent tumor development and light sensitivity. Sea urchin fisheries have expanded so greatly in recent years that the natural population of sea urchins in Japan, France, Chile, the northeastern United States, the Canadian Maritime Provinces, and the west coast of North America from California to British Colombia have been overfished to meet the great demand. Not surprisingly, the decrease in supply and the continued strong demand have led to a great increase in interest in aquaculture of sea urchins. Most, if not all, sea urchin fisheries have followed the same pattern of rapid expansion to an unsustainable peak, followed by an equally rapid decline. World landings of sea urchin, having peaks at 120,000 mt in 1995, are now in the state of about 82,000 mt. However, over half this catch comes from the recently expanded Chilean fishery for Loxechinus albus. In Europe, the sea urchin stocks (Paracentrotus lividus) of first France and then Ireland were overfished in the 1980s to supply the French markets. However, these decreasing patterns clearly reflect the overexploitation of most fishery grounds and highlight the need for aquaculture development, fishery management and conservation strategies. While the wild stocks decline, high market demand for food, nutraceuticals and pharmaceuticals, increases the price of the product and thus, culturing is most likely to become commercially viable. As this review shows, there have been dramatic progresses in the culture techniques of sea urchins in the last 15–20 years; we can conclude that currently the major obstacles to successful cultivation are indeed managerial, cultural, conservational and financial rather than biological. Therefore, the fate of the sea urchin fishery is closely connected to that of the fisheries, whose fortune will ultimately depend upon the stock enhancement, culture improvement, quality roe production and market forces that will ultimately shape this growing industry in a sustainable manner.

Abstract:

Mud crab (Scylla paramamosain) is one of important export commodity and valuable edible crabs in the market. The feeding technology implemented by farmer was remained simple. One of those principles was by implementing proper feeding of different dosage and lipid source on the growth and survival rate. The objectives of the research were the effect of different dosage source of lipid oil on the growth and survival rate of Mud crab (S. paramamosain) under technology of battery system conditions. The research used 180 mature mud crabs (S. paramamosain) and plastic cage with 30×30×20 cm measurement captured in the Petebon waters. The initial weight of those crabs was 143.3±2.5 g. The Experiment used Completely Random Design as follows treatment were applied with 4 treatments and 3 replications those were 1% feed biomass per day (A), 3% feed biomass per day (B), 5% feed biomass per day (C) and 7% feed biomass per day (D). The feeding was conducted twice a day (morning and afternoon). Data collection consisted of the growth, survival rate and water quality (i.e., Temperature, pH, DO, Salinity, Ammonia and Nitrite). Data was analyzed by ANOVA and Duncan Test and water quality used descriptive analysis. The result showed that application of artificial feed were significant effect (P<0.05) to the growth, survival rate and was highly significant in influencing the FCR, PER and NPU (P<0.01). Treatment B (3% feed biomass per day is the best treatment. It is giving the highest growth that is 57.93±1.68 g, survival rate (83.33±5.77%), FCR (1.08±0.03), PER (45.94±0.30), NPU (34.7167±3.163), moulting (3.90%). In general water quality of the rearing of mud crab used for the study is still within a good range for growth and survival rate of mud crab.

Abstract:

The total lipid content, fatty acid composition and tocopherol content of muscle lipids of eleven fresh water fishes belongs to Cichlidae, Anabantidae, Siluridae, Cyprinidae, Channidae families lived in reservoirs in Sri Lanka were studied. Muscle lipid contents were varied between 1.6 - 41.5% of the fishes that having omnivorous, carnivoros and herbivorous feeding habits. Walking cat fish (Clarius branchysoma) having omnivorous feeding habit showed the highest total lipids (41.5%), polyunsaturated fatty acids (PUFA) (39.9%) and α-Tocopherol (29.65mg/g) in the muscle. The ratio of total n-3 to n-6 fatty acids in Walking cat fish is 1 confirmed consumption of cat fishes favourable for human health and has a particularly beneficial effect in preventing cardiovascular diseases. Tilapia (Tilapia moassambica), and Climbing pearch (Anabas testudineus) having omnivorous feeding habit showed 15.73 and 12.55% total lipids in the muscle and contained 5.6 and 2.5 mg/g α-Tocopherol respectively. However, Tilapia (Tilapia niloticus) shows very low total lipid (1.69%) and tocopherol (0.08mg/g). Fresh water shark (Wallago attu) having carnivorous feeding habit shows 11.29% total lipids, 4.02mg/g α-Tocopherol and 36% PUFA in muscle. Similarly, Rohu (Labeo rohita) having herbivorous feeding habit contained 10.84% lipids, 6.61mg/g α-Tocopherol and approximately 90% unsaturated fatty acids. Results of the study reveled that the lipid content, fatty acid composition and tocopherol content in the muscle of the freshwater fishes in Sri Lanka was not significntly influenced by the feeding habits of the fishes and no relationship with the families.

Abstract:

Aquaculture in its versatile form is getting popular in all parts of the world with indigenous technologies and approaches. Indeed it is essential to ensure food security and nutritional demands of growing populations. Organic practice of aquaculture is equally important while propagating scientific farming process in order to make the entire process sustainable and eco-friendly. Toxicological studies carried out in model organisms like Tilapia brought out interesting results with applications in farming practices. Various toxins brought into the system through aqua feeds and by way of chemicals for pond preparations are causing moderate to severe harmful effects to aquatic organisms and to the end users. The impact of toxins like Aflatoxin B1 seen associated with feeds still remains to be a serious threat. One of the viable alternatives would be to integrate the use of live feeds as well the formulated feeds. More and more feed formulations using natural algal and sea weeds extracts could also serve well to make the entire process more organic in nature.

Abstract:

“Pearl spot” an Asian Cichlid, Etroplus suratensis is an important delicious food fish use in aquaculture. This fish naturally get acclimated to fresh water and capable of withstanding wide variation in salinity thus making its culture in enclosed and brackish water quite feasible. Etroplus is an predominantly an herbivore feeding mainly an aquatic micro and macrovegitation. Ashtmudi Lake is in the Kollam District of Kerala state in India. Etroplus is distributed all over the Lake. This species show difference in palatability aspects available from different sites of the lake. Kanjiracode area of this lake is famous for its special taste of pearl spot. Hence an attempt was made to evaluate and confirm how far the food habits of this species on ecologically different areas of this lake have an influence on the proximate composition. Five site of the lake were selected for the present study. Different biochemical variables of the muscle and gut content analysis was done and results were statistically analyzed. Fishes from the Kanjiracode site at all seasons show higher level of filamentous algae(43%) consumption that always predominately present naturally at this site and high level of fat content(2.87%) compared to other sites. Aromatic amino acids tyrosine and phenylalanine present in this fish especially at site1 was significantly at higher level. Phenylalanine was found to significantly enhance the umami taste. The fishes from Kanjiracode area showed most palatable due to the high value in fat content. Lipid content is an aspect affecting the flesh taste in many fish species. The fat content difference and amino acid differences due to the algal feed consumed by the fish and that those consuming maximum algal feed have more fat content which was contributed by this feed.

Speaker
Biography:

Andie John Tadeo has completed his Masteral degree at the age of 28 years from the College of Fisheries, Central Luzon State University, Nueva Ecija, Philippines. Currently, he is one of the Instructors of Don Mariano Marcos Memorial State University-Institute of Fisheries, Santo Tomas, La Union, Phlippines.

Abstract:

Giant gourami has become one of the main species being cultured in southeast Asia and is in great demand in the aquaculture industry. The main constraint in giant gourami culture is the source of fry that should be standardized for commercial scale propagation. Assessment of growth performance, survival and body protein of giant gourami larvae fed with different types of live food organisms was conducted to identify the most suitable live food for larval rearing. Growth performance [mean final weight (FW) and length (FL)] of giant gourami larvae was significantly highest in enriched Moina (55.3±0.7mg and 16.27±0.29 mm), followed by unenriched Moina (41.0±0.6 mg and 14.73±0.17 mm), unenriched P. redivivus (31.7±0.3 mg and 10.47±0.35 mm), unenriched Artemia (31.0±0.3 mg and 12.20±0.23 mm), enriched Artemia (31.0±0.3 mg and 13.20±0.61 mm), enriched P. redivivus (31.0±0.3 mg and 10.53±0.75 mm) and mixed-zooplankton (19.7±0.9 mg and 8.87±0.24 mm). Highest mean survival of giant gourami larvae was obtained in enriched Moina (96.95±1.21%) but was not found to be significantly different from unenriched Moina (94.17±0.96%), enriched Artemia (87.78±0.55%) and unenriched Artemia (87.22± 5.30%). The lowest mean survival rate was obtained in Mixed-zooplankton (74.72±1.47%) but was not significantly different from those of unenriched P. redivivus and enriched P. redivivus (77.77± 4.82% and 83.33± 3.47%, respectively).

Zaleha Kassim has completed her PhD in 2001from Universiti Putra Malaysia, Serdang. Her field of study is taxonomy and some ecological aspect of harpacticoid copepods. She is the head of a marine research station which focus on the aquaculture and oceanography. She involves in teaching the undergraduate and postgraduate students in the field of aquaculture and oceanography. She is active in innovative and product invention research particularly in live feeds study. She leads many applied type of research grants as well as knowledge tranfer program grant.

Abstract:

Copepods have been found as one of the best live feed in aquaculture. This study was carried out to determine the development time, growth performance and fatty acid content of a marine copepod, Amphiascoides neglectus, potentially become live feed for marine larval rearing. The laboratory experiments were designed to expose the population of A. neglectus to different sets of temperature, pH and salinity treatment. The copepods were maintained in the combination of salinity of 15, 25 and 35ppt, pH of 5,7,9 and temperature of 25, 28,35oC for 25days under hygienic condition. Fatty acid content was determined using gas chromatography method. The life cycle consists of six naupliar stages, five copepodite stages and an adult stage. Total development time of each life stages was from 9±3.61 h to 17 ±2.65 h and range from 53.86 µm to 593.98 µm in size. Nauplii, copepodites and adult stage showed highest population density when cultured in 28oC, salinity 25ppt and pH9 (T28P9S25). The bad growth performance was shown when they were cultured in 35oC, salinity 15 and pH5 (T35P5S15). A.neglectus cultured in T28P9S25 demonstrated the highest fatty acid contents with linoleic acid C18:2n-6 (LA), eicosapentaenoic acid C20:5n-3 (EPA), docosahexaenoic acid C22:6n-3 (DHA), arachidonic acid C20:4n-6 (ARA) and linolenic acid C18:3n-3 (LNA). The finding of this study could become the baseline for the optimum culture condition of A.neglectus.

Abstract:

Sea perch (Lateolabrax japonicus), an economically important cultured fish species in Asian, has been challenged by RNA virus in recent years. Nervous necrosis virus (NNV) consisting of two co-encapsidated positive-sense RNA segments has been identified as the mainly cause of high mortality of mass larval-stage sea perch. The RIG-I-like receptors (RLRs) play a major role in sensing RNA virus infection to initiate and modulate antiviral immunity in low order vertebrates. To decipher the mechanisms of RLRs response to NNV in sea perch, we identified an NNV (strain SBN147), established two cell lines (LJB cells and LJF cells) from the brain of sea perch and cloned the LGP2, MDA5, MAVS and other related genes in RLRs signal pathway from the sea perch. Quantitative RT-PCR analysis showed that mRNA of these genes were widespread expressed in the tested tissues of healthy fish and significantly up-regulated post NNV infection. Furthermore, time course analysis showed that these genes transcripts significantly increased in the spleen, kidney and liver tissues after NNV infection. LjLGP2 mRNA expression was rapidly and significantly up-regulated in LJB cells after poly I:C stimulation and NNV infection. RNA interference experiment demonstrated that silencing of LjMDA5 significantly increased NNV replication in NNV infected LJF cells. The viral gene transcription of NNV was significantly decreased in LjMAVS over-expressing LJB cells. The present results suggest that RLRs may play a vital role in antiviral innate immune against NNV in sea perch.
