Globally-recognized authorities involved in every step


Our highly skilled technical team at DyneAquaculture was strategically assembled and has over 150 years of combined technical expertise. These seafood experts are globally-recognized authorities in raising fish and shellfish in closed containment systems in both saltwater and freshwater. They are also experts in infectious diseases and their prevention, quality assurance, and operating efficiency for harvest and processing.

CPR instructor (American Heart Association), Lifesaver (BSAC), Advanced Lifesaver (American Red Cross), fish biologist, fish culturist, scientific editor, and Fulbright Professor. Dr. Tucker is a Certified Fisheries Scientist of the American Fisheries Society, Fellow of the American Institute of Fishery Research Biologists, First Class Diver No. 456 of the British Sub-Aqua Club, Fourth Degree Diver of the World Underwater Federation (CMAS), and has been on the Roster of Experts in Aquaculture of the Food and Agriculture Organization of the United Nations. He raised and conducted research on 40 kinds of fish, including: eels, menhaden, anchovies, minnows, common snook, tarpon snook, barramundi, hybrid striped bass, black sea bass, Nassau grouper, dolphin, snappers, sheepshead, seatrout, spot, whiting, black drum, red drum, tilapia, sergeant major, striped mullet, white mullet, wrasses, spadefish, windowpane flounder, and triggerfish. Dr. Tucker developed and tested feeds for: common snook, barramundi, sunshine bass, Nassau grouper, spotted seatrout, red drum, and black drum, and developed a feed that was tested on Florida pompano. Reared snook, barramundi, groupers, sheepshead, and mullet were stocked in natural habitats and monitored. He also raised: bacteria, amoebas, protozoans, diatoms, microalgae, macroalgae, land plants (e.g., corn, beans, tomatoes, peppers, mangoes, seagrapes, flowers), fungi, sponges, hydrozoans, jellyfish, sea anemones, rotifers, snails, mussels, clams, oysters, bryozoans, polychaete worms, oligochaete worms, leeches, roundworms, brine shrimp, food shrimp, crabs, barnacles, copepods, cladocerans, isopods, arrow worms, tunicates, insects, reptiles, amphibians, birds, and mammals. Dr. Tucker has conducted research projects on fish in North Carolina, South Carolina, Florida, California, Bermuda, Bahamas, Cayman Islands, St. Thomas, Guam, Palau, and Australia (5 years in other countries), and has made scientific visits to, and lectured in, 19 additional countries. He taught students (from 29 countries) at Indian River State College, Florida Atlantic University, Florida Institute of Technology, Hampton Mariners’ Museum (North Carolina), Bermuda Biological Station for Research, University of Puerto Rico, University of the West Indies (Jamaica, Fulbright Professor for 10 months), National Fisheries Institute (Mexico), National Polytechnic Institute (Mexico), and Curtin University of Technology (Australia), and was on the founding board of directors of a Montessori school. Non-college courses (36) taught included: basic, advanced, environmental, night, wreck, and deep scuba diving, CPR, emergency oxygen administration, underwater biology, seashore life, and marine science. College courses (35) taught were: biology, integrative biology, life science, biodiversity, marine biology, marine ecology, oceanography, aquaculture, marine fish culture, survey of biological literature, and scientific writing. College topics taught included: taxonomy, development, reproduction, nutrition, energetics, health, water chemistry, laboratory methods, and field methods, with introductions to molecular biology, cell biology, microbiology, biochemistry, physiology, genetics, evolution, behavior, and toxicology. Dr. Tucker has published more than 80 scientific articles and book chapters (on ecology, reproduction, development, nutrition, physiology, microbiology, toxicology, behavior, aquaculture, and fish stocking); the 760-page textbook Marine Fish Culture (1998), which has been sold in more than 100 countries; and the 61-page Chapter 18, Marine Fish, in the 645-page second edition of the textbook Aquaculture: Farming Aquatic Animals and Plants (2012).

Dr. Sarah Blain Kennedy - V.P. of Veterinary Sciences and Quality Control

Dr. Sarah Blain Kennedy received both a BA and an MA in pre-veterinary medicine and marine biology from Boston University, and a DVM from the University of Wisconsin. She has practiced veterinary medicine on small and large mammals, birds, reptiles, and fish.

Dr. Kennedy’s practice includes an emphasis on health, reproduction, behavior, dermatology, and emergency medicine, as well as general practice.   A major specialization has been fish health management, including development of methods to control and monitor the microbiology of the rearing environment.

She has been a pioneer in the detection, isolation, identification, culture, and use of probiotic (beneficial) bacteria for marine fish culture in the US. Dr. Kennedy is well-versed in animal health regulations, including those of the USDA, FDA, and EPA. She has lectured, taught courses on fish health, and has been a consultant in several countries. She has a unique perspective on the aquaculture industry and invaluable experience as a marine biologist and veterinarian.

Dr. Bruce Calman - V.P. of Production and Operations

Dr. Bruce Calman received his doctorate from Syracuse University in New York. He was one of the leading research scientists at the Whitney Laboratory and the University of Florida. He helped develop a breakthrough technology for on-demand spawning of high-value ocean species.

This technology allowed for spawning year round as opposed to short term spawning cycles lasting only weeks.

Dr. Calman pioneered techniques that increased survivability of fingerlings from 5% to over 90%. In addition, Dr. Calman led a team of scientists that was innovative in the fields of genetics, nutrition, and water quality. Many consider Dr. Calman one of the world’s premier scientists in aquaculture.
