Technique for Estimating Trawl Efficiency in Catching Brown Shrimp (Penaeus aztecus), Atlantic Croaker (Micropogon undulatus) and Spot (Leiostomus xanthurus)

Year: 1976

Type: article

Abstract: Mark-recapture experiments conducted in a small 17.5 ha lake in Barataria Bay, Louisiana, were used to estimate the efficiency of a 4.9-m (16-foot) otter trawl in capturing brown shrimp, Atlantic croaker, and spot in water 1.5 m deep. The trawl was observed to sweep an area 2.5 m in width. Trawl efficiency was determined to be approximately one-third to one-half for brown shrimp, one-fourth for Atlantic croaker, and only 6 percent for spot.
