Dr. Jack Rensel, Principal Investigator
Jack Rensel is a leading expert in aquaculture research and environmental issues. He was responsible for much of the basic research and analysis that led to the first federally-sanctioned state permits for net pen aquaculture in the U.S. Dr. Rensel conducts research on current aquaculture and food web topics, including the beneficial food web aspects of optimally sited commercial net pens, which constitutes a new frontier for further exploration using promising tools such as stable isotope analysis.
With NOAA, USDA and industry support, he has been a partner with the AquaModel team in developing, testing and validating the comprehensive water column and benthic effects GIS-model for salmon or other fish species net pens that may be used for a single farm or array of farms throughout an entire coastal region. Dr. Rensel works on projects in North and South America, the Caribbean Sea, South East Asia and in other locations worldwide.

Dr. Rensel is a recognized international expert on harmful algal bloom dynamics and has been involved in development and testing of mitigation strategies for farmed and wild stocks. He was lead author of a recent publication explaining how harmful blooms were strongly linked to extreme interannual variation of Fraser River sockeye salmon marine survival over the past 20 years.

As principal of Rensel Associates Aquatic Sciences, he has written more than twenty peer-reviewed articles or book chapters and hundreds of technical reports. His clients include the largest seafood processing and distribution firm and the largest fish farming companies owned and operated in the U.S. He is also a consultant to Earth Justice Hawaii on water and sediment quality issues.
