Day 1 :
Professor Emeritus, Ehime University, Japan
Keynote: Promotion of CO2 assimilation by effective use of NOx and NP is best method to produce much fish and protect global warming
Time : 09:00 am to 09:40 am
Dr Ozaki has served as the Professor at Ehime University,Department of Chemical Industry and as the Visiting Professor at various reputed universities of the world including University of Konstanz, New York State University and Shangdong University. He had also been a Research Chemist at The Institute of Physical and Chemical Research, Tokyo, Japan. Currently he is the Professor Emeritus at the Ehime University, Japan. Dr Ozaki has been the recipient of Hatsumeishou (Invention Prize) for the invention of Carmofur (antitumor agent), Gakujutsusho (Academic Prize) from the Japan Chemical Society for the synthesis of biologically active compounds (Carmofur, IP3), Fulbright Award and the Alexander von Fumboldt Award.
The earth is warmed up by the burning of 1.4 billion tone fossil releasing 360 billion tones CO2 in 2016. If we can compensate the generation of CO2 by CO2 assimilation, global warming can is protected. To promote CO2 assimilation, supply of nutrient N and P is essential. About 14.4 billion tone NOx is produced when fossil is burned .Some country hate NOx as pollution gas and do NOx elimination. Some country does not do NOx elimination and use NOx as fertilizer. NP in drainage is also hated as pollution substance at some country and eliminated. Use of NOx and NP as fertilizer or eliminate these give great influence on growth of plant, CO2 assimilation, production of grain, fish, electricity price,GDP. When we look at fish industry of many country, the country which use NOx and N,P in drainage are producing much fish and fixing much C02. China,Indonesia,India, Vietnam do not eliminate NOx and do not do drainage treatment . NOx is a promotor of plant growth and CO2 assimilation. Therefore NOx elimination gives great damage on growth of plant and plankton, production of fish, grain. To eliminate NOx, ammonia is used. By this reaction, precious fertilizer is destroyed by other fertilizer. This is tremendous loss. The country who do this reaction like USA, Japan,Germany ,Italy are consuming much fossil generating much CO2 for elimination of NOx. Therefore electricity price is higher than no NOx elimination country. The country whose electricity price is low can produce well with low price. Then producing industry progress and GDP growth rate become higher.Therefore NOx elimination and drainage NP elimination should be stopped to produce much fish and protect global warming.
Senior Professor, Vellore Institute of Technology, India
Keynote: Importance of Molecular Endocrinological studies in optimization of Aquaculture: An overview with finfish and shellfish models
Time : 10:10-10:50
Anilkumar Gopinathan, Senior Professor at the Vellore Institute of Technology, India, had his postdoctoral training (hormone receptor genes) from the University of Oklahoma, USA. Two-time Grantee of the International Foundation for Science (IFS, Sweden), Anilkumar is also the Scientific Advisor to IFS, and contributed significantly to the field of crustacean molecular endocrinology. He had been Visiting Scientist to University of Gdansk (Poland), Belarus State University and University of Oklahoma (DST-NSF). Recipient of St. Berchman’s Best Teacher award, Anilkumar has also chaired scientific sessions in several international conferences and delivered plenary lectures on topics with a bias to aquaculture.
Optimization of aquaculture would require in-depth understanding of metabolism of the candidate species, especially with respect to that of growth and reproduction, the two major high energy – demanding processes. In fishes, growth hormone and insulin-like growth factors are known to play major role in development and metabolism; studies have allowed discernment of a complex, tissue-specific collection of IGF-I transcripts, through alternative splicing. Recent studies have enabled us to formulate synthetic hormones that could shorten the growth time needed for farm-raised fish to reach market size. Interestingly in crustaceans (crabs, shrimps etc.), regulatory mechanisms rely on the intricate balancing between stimulatory and inhibitory principles. Here, the ecdysteroids, secreted by the Y - organ, and the terpenoid methyl farnesoate, secreted by the mandibular organ act as stimulatory hormones for growth and reproduction respectively. Further, the neurosecretory cells from the decapod eyestalks are known to produce molecules that could inhibit growth and/or reproduction. Information gathered on the inhibitory hormones from the eyestalk has paved the way for using deeyestalking as a potential tool for induced breeding in female shrimps and lobsters. However, recent observations reveal that in spite of its efficacy in artificially induced egg maturation in female crabs and shrimps for one cycle, deeyestalking is no more considered as a technique of consistency for induced breeding. Results of recent investigations on hormone receptors provide us with valuable clues on viable possibilities for inducing growth and reproduction, and optimization of aquaculture, to be discussed during the proposed talk.
Shrimp Aquaculture Consultant (Former; Chief Technical Advisor & Consultant for FAO projects of the UN and WB)
Keynote: Various intensive shrimp farming systems in Asia: Commercial implementation of biofloc and RAS production systems help control shrimp farming diseases
Time : 11:10 am to 11:50 am
Dr Nyan Taw received his Ph.D. from the University of Tasmania, Australia. He served as short term consultant for FAO and World Bank funded projects in Saudi Arabia and Vietnam. He was a technical counter-part for ADB and JICA projects to develop the fisheries sector in Myanmar from 1976 to 1987. In 1988, he joined the FAO of the UN and served in aquaculture projects in Indonesia, Vietnam and the Philippines culminating the position of CTA. From 1995, Dr Nyan served as Production Director at a number of locations in Indonesia. In 2002, he joined CP Indonesia, as VP where he initiated biofloc technology. Later he served as SVP for Dipasena Group, Indonesia.
Before the mid-1990s, the major diseases affecting the farmed shrimp industry were of bacterial origin. But in Asia and from late 1994, the appearance of various, major viral diseases – like White Spot Syndrome Virus (WSSV), Yellow Head Virus (YHV), Infectious Myonecrosis Virus (IMNV) and others – led to changes in the design and operation of some shrimp farms to help prevent outbreaks and dissemination of viral diseases. More recently, WSSV outbreaks in Saudi Arabia in farming operations for Indian white shrimp (Penaeus indicus) provided more evidence that additional biosecurity was needed. And since 2009, outbreaks of a new bacterial disease, Acute Hepatopancreatic Necrosis Syndrome (AHPNS) – which started in China and spread to Asia and later Central America in 2015 – has caused losses of billions of dollars. In Australia WSSV outbreak in early 2017 at black tiger shrimp (Penaeus monodon) farms provide additional evidence for the need to change shrimp production systems.
Because of old and newly emerging viral and bacterial diseases affecting their farmed shrimp industry, some years ago various Asian countries started developing and using biofloc and recirculation aquaculture system (RAS) production technologies and/or treating incoming water for culture operations and wastewater treatment as biosecurity measures for disease prevention and control. Many production systems are used by Asian shrimp growers – from single-pond base management to larger RAS systems – but many have yet to reduce their environmental impact due to their wastewater discharges.
Examples of different biofloc and recirculation aquaculture (RAS) shrimp farming systems used in Asia in the last two decades, including some of the projects I have personally been involved with and provided technical expertise, as well as some perspectives on these technologies are provided. Large integrated shrimp farms in Indonesia: Dipasena group in Lampung, PT CPB in Lampung and PT SAJ in Sumbawa and Blue Archipelago Bhd projects in Kedah and Terengganu in Malaysia.
In any aquaculture business, sustainability of a system can improve profits. With emerging disease problems, treating wastewater discharged from farming facility or RAS is of utmost important. What investors, shrimp farmers and technicians need to be aware of is that, whatever waste is discharged into the environment, it will likely com/e back to you in the form of disease sooner or later.
