NMFS is adjusting the commercial aggregated large coastal shark (LCS) and hammerhead shark management group retention limit for directed shark limited access permit holders in the Atlantic region from 45 LCS other than sandbar sharks per vessel per trip to 25 LCS other than sandbar sharks per vessel per trip. This action is based on consideration of the regulatory determination criteria regarding inseason adjustments. The retention limit will remain at 25 LCS other than sandbar sharks per vessel per trip in the Atlantic region through the rest of the 2016 fishing season or until NMFS announces via a notice in the Federal Register a fishery closure is warranted. This retention limit adjustment will affect directed shark limited access permit holders fishing for LCS in the Atlantic region.
