Supporting material for stock assessment of NAFO Division 4TVn southern Gulf of St. Lawrence Atlantic herring (Clupea harengus) in 2022-2023 / Laurie Maynard, Jacob Burbank, Rachel DeJong, François Turcotte,... : Fs70-5/2024-058E-PDF
"Atlantic Herring (Clupea harengus) in Northwest Atlantic Fisheries Organization (NAFO) Division 4T, referred to as the southern Gulf of St. Lawrence (sGSL), consists of two spawning components, spring spawners and fall spawners. This document presents the most recent information on trends in abundance, distribution, and harvest for the spring and fall spawning Herring components in NAFO Division 4T. This includes catch-at-age and catch-per-unit-effort (CPUE) indices, fisheries-independent acoustic indices, experimental gillnet survey indices, mesh selectivity, fishery-dependent acoustic indices and catches in the multi-species bottom trawl survey of the sGSL. The data and indices are reported for the sGSL for the spring spawners, and regionally-disaggregated (North, Middle, and South regions) for the fall spawners where applicable. This information is the basis of the assessment of spring and fall spawning 4TVn Atlantic Herring. … This document is meant to support the stock assessment of Atlantic Herring in 4TVn by presenting data sources and data changes between the 2022 and 2024 assessment, but does not include details on model methodology"--Abstract, page xi.
