Alaska Fisheries Science Center 2020 Groundfish Seminar Series - Sean Rohan
A framework for simulating latitudinal catchability variation.
In recent years, unprecedented warm conditions facilitated a rapid northward range expansion of subarctic fish in the Bering and Chukchi Seas. Due to extreme latitudinal and seasonal variation in day length, these range shifts may change the visual environment where fisheries and fishery-independent surveys encounter subarctic fish, which would affect catchability because vision plays a role in the capture process. In this talk, I will present a model to simulate the effects of latitudinal shifts on the catchability of bottom trawl fisheries and fishery-independent surveys.
