The Fish Trawl Survey was developed to quantify the seasonal occurrences of migratory fish populations, whereas scientists had previously relied on anecdotal information.
Realizing its value as a documented record of long-term fluctuations in fish and invertebrate abundance, Fish continued the trawl survey until he retired in 1966. The trawl was then passed to H. Perry Jeffries, late professor at the Graduate School of Oceanography, who maintained the survey for more than 30 years until he handed it over to Jeremy Collie in 1998. With over 63 years of data, the Graduate School of Oceanography Fish Trawl Survey is one of the longest continuous records of fish and invertebrate relative abundance in the world.
Data collection on the Graduate School of Oceanography Fish Trawl Survey has expanded over time and now includes: abundance and biomass of all fish and invertebrate species; surface and bottom temperature, dissolved oxygen, and salinity at each survey site; and total length measurements and sex determination of winter flounder, Pseudopleuronectes americanus. The long term data are stored in a database at the lab of Jeremy Collie and can be requested by emailing our team.
