Quantitative approaches to evaluating the contribution of release programs to fisheries management goals
Dr Kai Lorenzen (University of Florida, Unites States)
Dr. Kai Lorenzen is Professor of Integrative Fisheries Science at the University of Florida, where he leads an interdisciplinary research program focusing on the role of supply-side interventions such as stock and habitat enhancement in fisheries management. He is best known for his work on the population dynamics and quantitative assessment of enhanced fisheries and for related research on size- and density-dependent processes in fish populations. Dr. Lorenzen has also developed an interdisciplinary framework for analyzing enhancement fisheries systems. With Lee Blankenship and Ken Leber he recently revised a set of guiding principles for the development or reform of stock enhancement programs known as the ‘responsible approach’. Dr. Lorenzen holds a Master’s degree in Biology with Mathematics from Kiel University (Germany) and a PhD in Applied Population Biology from the University of London. He worked as a fisheries development consultant, mostly in Asia, from 1992 to 1996. He joined the faculty of Imperial College London in 1997 and move to the University of Florida in 2010.
Strategic mixing of fishery management, aquaculture and stock enhancement: Comparison of case studies of the Chesapeake blue crab (Callinectes sapidus) in the United States and the swimmer crab (Portunus trituberculatus) in three provinces of China.

Dr. Anson “Tuck” Hines is the Director of the Smithsonian Environmental Research Center (SERC), a 1,000 ha located on Chesapeake Bay in Edgewater, Maryland, USA. He provides oversight and leadership of research, professional training and public education programs in global change, landscape ecology, ecosystems in coastal regions, and population & community ecology. Dr. Hines has a B.A. degree in Zoology from Pomona College and a Ph.D. in Zoology from the University of California at Berkeley. He has conducted research on coastal ecosystems in Chesapeake Bay, Florida, California, Alaska, Belize, Japan, and New Zealand. Dr. Hines has been project leader on a diverse array of research, including: effects of thermal discharges of coastal power plants; sea otters and kelp forest ecology; long-term ecological change in Chesapeake Bay; marine food web dynamics; predator-prey interactions; impacts of fisheries, aquaculture and fishery restoration; crustacean life histories; and biological invasions of coastal ecosystems. He has studied the biology of crabs around the world and is an expert on blue crabs. Over the past 10 years he has been a Principal Investigator for the Blue Crab Advanced Research Consortium to test the feasibility of responsible stock enhancement of the blue crab fishery in Chesapeake Bay. He has published more than 140 articles in technical journals and books. He has served as major advisor for 20 Post-doctoral fellows, 10 Ph.D. students and 9 M.S. students, and mentor for more than 125 undergraduate Interns.
Professor Cheng Yongxu (Shanghai Ocean University, China)
Professor Cheng Yongxu is Director of the Department of Nutrition and Physiology in the College of Aquaculture and Life Sciences, Shanghai Ocean University. Over 20 years, he has conducted research on the aquaculture of crab species, particularly their nutrition and reproduction and has published more than 150 papers. His research interests are: crab nutrition in relationship to their reproduction, growth and development (nutritional reproduction); the lipid nutrition of crab and its metabolic biochemistry, Reproductive biology of crabs, and the mass culture of live food (Rotifer, Artermia, Cladocera) for Aquaculture and its nutritional enrichment. His research on Chinese mitten crab Eriocheir sinensis has taken some important roles in improving the development of national aquaculture. Currently, he is focusing his research on the swimming crab Portunus trituberculatus, the third most important crab species produced by aquaculture in China. In 2009, he and his colleges successfully held the "International Symposium on Aquaculture, Biology and Management of commercially important Crabs-2009" (ISABMC-2009) at the Shanghai Ocean University. He is supervising one post-doctoral fellow, 3 Ph.D students and 18 MSc students.
Rearing and genetic effects on fitness of artificially-produced animals in the wild: empirical evaluation of large-scale fishery stock enhancement programs
Dr Shuichi Kitada (Tokyo University of Marine Science and Technology, Japan)
Dr. Shuichi Kitada is a Professor in the Department of Marine Biosciences, Tokyo University of Marine Science and Technology (TUMSAT), Japan, specializing in fishery resource enhancement and conservation. He teaches graduate and undergraduate courses in fish stock enhancement, ecological bioinformatics and conservation genetics. He has a B.A. degree in Fishery Science from Hokkaido University (1976) and a Ph.D. in Agriculture from the University of Tokyo (1991). He worked for the Japan Sea Farming Association, which subsequently merged with the Fishery Research Agency, for two decades in quantitative evaluation of effectiveness of marine stock enhancement programs. He authored “Stock enhancement assessment with Japan examples” in 2001, and coauthored “An Introduction to Biostatistics” with Sakutaro Yamada in 2004, and published over 100 peer reviewed articles. He has been a member of the Scientific Committee for the International Symposium on Stock Enhancement and Sea Ranching since 1996, and the scientific board of the Invasive Alien Act, Ministry of Environment. His current interest is to evaluate impacts of hatchery-reared animals and alien species on wild populations and statistical modeling for genetic data analyses. He has been leader of two research projects at TUMSAT; Conservation Genetics Group and Monitoring and Evaluation of Anthropological Impacts on Biodiversity. Dr. Kitada is an adjunct Professor at the Agricultural Bioinformatics Research Unit, Graduate School of Agricultural and Life Sciences, the University of Tokyo.
Perspectives on ‘A Responsible Approach to Marine Stock Enhancement: An Update’: better integration with fishery assessment, management, and stakeholder involvement
Dr Ken Leber (Mote Marine Laboratories, United States)
Dr. Ken Leber is the Director of the Center for Fisheries Enhancement at Mote Marine Laboratory, an independent, non-profit research institution established in 1955 and located on the Gulf of Mexico in Sarasota, Florida, USA. His specialty is fisheries ecology and marine stock enhancement. He also provides oversight and leadership of research on fisheries-habitat ecology. Dr. Leber has a B.S. degree in Biology from George Mason University, an M.S. in Biology from East Carolina University and a Ph.D. in marine ecology from Florida State University. He conducted research on predator-prey dynamics in seagrass meadows in coastal systems of Florida. Since 1988 he has focused much of his research on developing and evaluating marine stock enhancement, with particular emphasis on optimizing release strategies and evaluating hatchery-wild fish interactions. He started his stock-enhancement research program in Hawaii with striped mullet and Pacific threadfin. In 1995, he coauthored ‘A responsible approach to marine stock enhancement’ with Lee Blankenship. In 1996, he began research on red drum and common snook stock enhancement in Florida. His current focus includes expanding use of hatcheries to evaluate ecological questions about wild stock recruitment dynamics and density dependence. He has published more than 40 articles in scientific journals and books. He has served as advisor for 3 Post-doctoral fellows, 5 Ph.D. students and 4 M.S. students. Dr. Leber is an adjunct Professor in the Fisheries and Aquatic Sciences Program, School of Forest Resources and Conservation, University of Florida.
