Abstract

For study CPUE, Catch composition and length frequency in surface narrow-barred Spanish mackerel gill net (Costal region of Sistan Va Baluchistan Province), a study was done in 6 fishing grounds in four months. 778 specimens belong to 25 species was catch and identified. Tuna fish (Auxis rochei rochei) with 135 specimens and 100% probability in all sampling places, is the large number and Nemipterus japonicus, Rachecentron Canadum and Epinephelus coioides with 3 species and 33% probability are the lowest number. Also, Sphyraena putnamiae with weight average of 3672 gr, has maximum weight and Acanthopagrus cuvieri with 271.4 gr has minimum weight.
