Abstract

Increasingefficiency of fishing is one of major goals of fisheries researchers. The aim of this study was to evaluate the efficiency of gillnet with three different colors of green, blue and white, and three different mesh size 3.75, 6 and 10 cm (STR) in Khuzestan waters. Data were recorded from three fishing harbor Arvand, Choobedeh of Abadan and Khoramshahr during 2008-2009. Simpson diversity and economic diversity index were used to analyze data. Results showed that economical index of green net was more than the other colors. In addition, the efficiency of 10 cm (STR) mesh size was higher than two treatments. In conclusion, results demonstrated that using green net with 10 cm (STR) mesh size is more economical.
