September 8, 2017 — NARRAGANSETT – Last week, the fishing vessel Karen Elizabeth docked home in Point Judith following a 10-day voyage that involved the study of flat fish populations and the methods used to catch various species. Formulated by the Northeast Trawl Advisory Panel, a group made up of fishing industry professionals, government bodies and various fishing councils, the research was examining the number of summer flounder, winter flounder and red hake off the coast of New England. The resulting data will go on to better inform catch and population estimates of each species and came about due to the collaboration of the National Oceanic and Atmospheric Administration (NOAA) and the local fishing industry.
On the NOAA side, John Manderson, a senior fisheries research biologist with specialties in field ecology, habitat ecology, fisheries ecosystem science and collaborative research working out of the organization’s Northeast Fisheries Science Center in New Jersey, served as the chief scientist on the project. Chris Roebuck, operator of the Karen Elizabeth, was representing the fishing industry. The crew onboard the vessel totaled 10 members – five researchers and five fishing professionals.
The goal of the study was to develop a quantitative understanding of two different modes of ocean-floor species surveying – one approved by the federal government and one designed by the fishing community for maximum efficacy. For this experiment, the third leg of the overall project, researchers were examining the catch rates of summer flounder, winter flounder and red hake. Previous and similar research conducted in 2015 was examining yellow-tail flounder and grey sole.
“My specialty has become collaborative research with the fishing industry,” said Manderson. “The reason for that is that at the scale of the ecosystem, experts in the fishing industry have much greater access to the ecosystem and as a result they have much better intuitions about what is going on in the ecosystem in real time, including changes in habitat occurring as a result of changes in climate, than we do. “
The fishing vessel Karen Elizabeth is a twin trawler equipped with two nets as close together as possible which can then be towed simultaneously at approximately the same speeds and for the same duration. These assets lend the boat well to research-based projects that involve comparing different survey methods literally side-by-side.
