NMFS revises Illex squid specifications and maintains previously approved longfin squid and butterfish specifications for the 2019 fishing year. This action is necessary to specify catch levels for the Illex squid fishery based on updated information on allowable catch levels and to provide notice that NMFS is maintaining the previously approved longfin squid and butterfish specifications. These specifications are intended to promote the sustainable utilization and conservation of the squid and butterfish resources.
