Description:

This study examines the CPUE estimates (calculated for this study as the number of fish of each species per effective hook at a station) from two fishery-independent longline surveys operating in the eastern North Pacific which are used to inform groundfish stock assessments: the International Pacific Halibut Commission (IPHC) annual halibut setline survey and the National Marine Fisheries Service (NMFS) Alaska Fisheries Science Center’s annual groundfish longline survey. Both surveys provide data from which CPUE estimates can be calculated, however the data recording methods differ. This study is not comparing the two surveys to each other but compares how the estimated CPUEs may change based on the method of data recording; thus, each survey is being compared to itself.
