Keynote Speakers
Understanding and Managing Fisheries Enhancement Systems
Dr. Kai Lorenzen
Dr. Kai Lorenzen is a Senior Lecturer in Aquatic Resource Ecology at Imperial College London. His work focuses on aquatic resource systems at the interface of capture fisheries and aquaculture including stock and habitat enhancements. Dr. Lorenzen holds a Ph.D. in Applied Population Biology from the University of London (UK), and a Master's degree in Biology with Mathematics from Kiel University (Germany). He worked as a fisheries development consultant before taking up his academic position, and maintains a strong interest in the practicalities of resource management which complements and often motivates his academic research. Over the past 10 years he has developed population dynamics theory and practical methods for the quantitative assessment of enhancements in a fisheries management context. The methods are now available in the EnhanceFish decision tool, developed jointly with Dr. Paul Medley. In parallel with his biological research, Dr. Lorenzen teamed up with social scientist Dr. Caroline Garaway and others to lead interdisciplinary field projects developing sustainable enhancements in Asian lakes and reservoirs. These complementary strands of work have led him to develop an integrated perspective on enhancement systems and the biological, economic and institutional factors that make them succeed or fail. His opening keynote will explore the nature of enhancement systems and their management, before reviewing the state of knowledge in key areas and outlining critical issues for consideration during the symposium and future research.
The Chesapeake Bay Blue Crab
(Callinectes sapidus): a Multidisciplinary Approach to Responsible Stock Enhancement
Dr. Yonathan Zohar
Professor Zohar is the Director of the Center of Marine Biotechnology (COMB), University of Maryland Biotechnology Institute (UMBI), where he leads a comprehensive multidisciplinary research and development program that applies the tools of modern biology and biotechnology to study, protect and enhance marine and estuarine resources. Under Dr. Zohar's leadership, COMB has become internationally known for its work covering aquaculture and fisheries biotechnology, marine functional genomics, microbial oceanography and extremophiles, marine environmental biotechnology and bioremediation, and marine natural products. Dr. Zohar's own basic and applied research focuses on the physiology, endocrinology and molecular biology of reproduction using finfish and other marine animal models. He is considered one of the world's leading authorities in the field of comparative endocrinology and is widely recognized for his achievements in applying basic hormonal concepts to develop technologies for reproduction control and hatchery production in commercially important marine species. Dr. Zohar also leads an innovative and interdisciplinary federal program on blue crab biology, hatchery technologies and stock replenishment, which he initiated in 2000 to address declining crab abundance in the Chesapeake Bay.
Dr. Zohar received his B.Sc. in Biology and M.Sc. in Oceanography/Marine Biology from the Hebrew University of Jerusalem, Israel. He received his Ph.D. in Comparative Endocrinology in 1982 from the University of Paris. During his 28-year research career, Dr. Zohar has published over 190 scientific papers, reviews and book chapters. He has received numerous awards and honors, organized multiple scientific symposia and is regularly invited to deliver keynote presentations in international conferences. Dr. Zohar has worked closely with industry and federal and state agencies, served on numerous international, national and state committees and boards, and been active in multiple educational and training programs.
