Alaska Fisheries Science Center 2020 Groundfish Seminar Series - Meadhbh Moriarty
Combining fisheries surveys to inform marine species distribution modelling
Examination of fish communities typically involves creating spatiotemporally-explicit relative abundance distribution maps using data from multiple fishery-independent surveys. However, sampling performance varies by vessel and sampling gear, which may influence estimated species distributions. A framework for combining fisheries surveys to examine distributions on a multi-regional scale, in this case the entire North East Atlantic region, will be presented. Here we use simulation studies to explore the effects of simulated differences in gear efficiency and then applied this methodology to fisheries survey data, while controlling for the use of multiple vessels and gears to collect the information.
