Description:Quantifying bycatch in the Hawaii deep-set longline fishery is required by the Magnuson-Stevens Fishery Conservation and Management Act (MSA), Endangered Species Act (ESA), Marine Mammal Protection Act (MMPA), Migratory Bird Treaty Act (MBTA), and their implementing regulations. With more than 100 species (some of which are listed as endangered or threatened) recorded as being caught in the Hawaii deep-set longline fishery, reliable estimates of each species’ total bycatch need to be computed in a relatively quick manner on a yearly basis. A probability sample and corresponding design-based estimators provide the framework for producing such estimates. Characteristics of the NOAA Fisheries Pacific Islands Regional Observer Pro-gram (PIROP), established to monitor bycatch, and the Hawaii deep-set longline fishery require a sampling design that can adapt to fluctuating observer coverage. This document is the first of a series of documents that describe the methods used to derive the required bycatch estimates. This document was written in 2015 and covers years 2002-2015.
