  • Description:
    A Federal regulation, mandated in 1981, closes the fishery conservation zone (FCZ) in the Gulf of Mexico off of the coast of Texas to fishing for brown shrimp beginning in late May until the middle of July when the area is re-opened to commercial fishing. The objective of this regulation is to essentially eli- minate fishing mortality on brown shrimp during a period of rapid growth in their life cycles. Analyses are performed to estimate the effects of these regulations on the amount of shrimp caught (and landed) and the value of the catch. The effects on catch are estimated in Nichols (1986) and his estimates are used to estimate the effects of the Closure on ex-vessel prices and value. According to Nichols, the Closure during May 1984 through mid-July 1984 resulted in an increase of 1.4 million pounds of brown shrimp. This increase in landings is estimated to have resulted in an increase in total revenue to the fishery of about $18.7 million. This report also presents preliminary estimates of the effects of the closed season from May 1985 through mid-July 1985. These preliminary estimates are made for the four month period, May through August, and are used by the Gulf of Mexico Fishery Management Council in their recommendations regarding the status of the regulation in the FCZ. Nichols (1986) estimates that the closed season during 1985 resulted in a loss of between 1.3 and 0.8 million pounds of brown shrimp. The estimated ex-vessel values for these losses in catch range between a loss of $5.2 million and a gain of $756 thousand to the fishery.
