The Atlantic States Marine Fisheries Commission has initiated a benchmark stock assessment for river herring to be completed in the summer of 2023. River herring is the collective name for two closely related species, alewife (Alosa pseudoharengus) and blueback herring (Alosa aestivalis), that return to rivers from Maine through Florida to spawn every year. The goals of the assessment are to evaluate the health of stocks along the Atlantic coast and inform management of these species. The Commission’s stock assessment process and meetings are open to the public.
The Commission welcomes the submission of data sources that will contribute to the goals of the assessment. This includes, but is not limited to, data on abundance including run counts and surveys, stocking, biological samples (sex, maturity, age, weight, length), life history information (growth, fecundity, natural mortality, sex ratio, spawning history), stock structure (tagging data, genetics), mortality (predator diet, anthropogenic sources such as hydropower dams), and catch (harvest, discard, fishing effort). An essential need is data to inform the stock assessment of discards and bycatch in other directed fisheries (e.g. the Atlantic herring fishery). For data sets to be considered, the data must be sent in the required format, with accompanying description of methods, to the Commission by July 1, 2022.
