May 1, 2019 — The following was published by the Atlantic States Marine Fisheries Commission: The Atlantic States Marine Fisheries Commission’s Atlantic Herring Management Board approved Addendum II to Amendment 3 of the Interstate Fishery Management Plan for Atlantic Herring. The Addendum strengthens spawning protections in Area 1A (inshore Gulf of Maine) by initiating a closure when a lower percentage of the population is spawning (from approximately 25% to 20%) and extending the closure for a longer time (from four to six weeks). The Addendum also modifies the trigger level necessary to reclose the fishery, with the fishery reclosing when 20% or more of the sampled herring are mature but have not yet spawned. These changes to spawning protections are in response to the results of the 2018 Benchmark Stock Assessment which showed reduced levels of recruitment and spawning stock biomass over the past five years, with 2016 recruitment levels the lowest on record.
Under Amendment 3, the Board uses a series of closures to protect spawning aggregations in the Gulf of Maine. Biological samples are used to annually project the start of the spawning closures. A recent analysis by the Atlantic Herring Technical Committee found that while the spawning closure system was significantly improved under Amendment 3, the protocol could continue to be strengthened by considering when, and for how long, a closure is initiated. Specifically, the analysis showed greater protection could be provided by initiating a closure when a lower percentage of the population is spawning and extending the closure for a longer time.
The states are required to implement Addendum II’s measures by August 1, 2019. The Addendum will available on the Commission website (www.asmfc.org) on the Atlantic Herring page by mid-May.
