Description:

Fishery-independent surveys are subject to unavoidable fluctuations in sampling effort over time, creating a need for efficient and flexible survey designs. Here we use simulation to evaluate the performance of stratified random survey designs in the Gulf of Alaska (GOA) bottom trawl groundfish survey using alternative stratifications and sampling effort allocations relative to the status quo stratified random sampling design across a range of total sampling effort scenarios (corresponding to 1, 2, or 3 survey boats).
