Biological implications of the closed corridor option for the Atlantic menhaden fishery

  • Description:
    The closed corridor management option, proposed by the Atlantic Menhaden Advisory Committee (AMAC) to the Atlantic Menhaden Implementation Subcommittee (AMIS), ~uld prohibit purse-seine fishing in an area extending from the beach to one mile offshore between cape Henry, Virginia, and cape Fear, North Carolina, November through January. The intent of the proposal was to protect young Atlantic menhaden ("peanuts"); 65% of all age-O fish landed were caught in this proposed closed corridor from 1978-1982. \ Biological effects of implementing the closed corridor policy were studied by hypothesizing three ways in Which fishing effort would be affected by the regulation, and then comparing each outcome with the anticipated landings without the regulation. The three hypotheses included: (I) No redeployment of fishing effort from the closed corridor, (II) complete redeployment of fishing effort from the closed corridor to outside waters, and (III) complete redeployment of fishing effort from the closed corridor to inside and outside waters. Hypothesis III was deemed the most realistic, and it exhibited the least gains in yield-per-recrult, ranging from 0.3 to 3.6% for the entire fishery. There is no biological advantage to the closed corridor management option since the gain is smaller than the predicted gain of 5.7% from a shortened menhaden season (Option 7) Which is the coastwide management measure recommended by the Atlantic State Marine Fisheries Commission (ASMFC) and Atlantic Mennaden Management Board (AMMB).
