The Current Speed, Depth and Catch Per Unit Effort of Bottom Gill Net in Southern Bulukumba Coast, South Sulawesi

Abstract

The objective of this study was to analyses catch per unit effort of bottom gill net related to current speed and water depth in southern Bulukumba coast, South Sulawesi. The study was conducted from April 2010 to November 2011. Fish catches were monitored to describe the predominant species caught. The length of gill net was 500 m and depth 5 m. Mesh size was 6 cm and shortening 45 %. Total catch was decrease with increase current speed. The highest catch was occurred in current speed 0.08 msec-1. In contras, the lowest catch was occurred in current speed 0.31 msec-1. Altogether 13 species were identified from 4 fishing efforts of bottom gill net. The average catch per unit effort per day in fishing ground with less than 20 m in depth was 21.2 kg. On the other hand, in more than 40 m in depth was 30.2 kg. Total catch was strongly related to water depth.
