A large number of fish and invertebrate species listed in fisheries management plans have insufficient data to conduct routine stock assessments.
A large number of fish and invertebrate species listed in fisheries management plans have insufficient data to conduct routine stock assessments. Nearly all assessment methods for data-poor stocks rely solely on catch data or one source of data for directly estimating population density. PIFSC scientists developed a modified integrated assessment model, focusing on developing extensions for the Catch-MSY method, or stock reduction analysis proposed by Martell and Froese (2012) and Taggart and Kimura (1982) and modified by Sabater & Kleiber (2014), by incorporating data other than catch times series that directly inform total mortality rates (e.g. changes in mean size), relative and absolute abundance estimates, and other life history information. This modified model is being applied to data-poor coral reef fish stocks throughout the Pacific Islands region, including Hawaii, American Samoa, Guam, and the Commonwealth of the Northern Mariana Islands. However these scientific analyses have not previously been applied for management purposes in the Pacific Islands region, so NOAA Fisheries conducted an independent peer review of the analyses to improve the scientific basis for management.
NOAA Fisheries announced the Center for Independent Experts review of "Length and Biomass Augmented Catch-Maximum Sustainable Yield Assessment Methods" in the Federal Register for October 13–16, 2015.
