Distribution of fish using the echo-sunder in Karah Island, Terengganu

Abstract

This research aims to study relative fish distribution and to produce a data base and determine the fish distribution pattern using Biosonics DT 6000 scientific echo sounders in waters around Karah Island, Terengganu. Data were collected 15 meters from the rocky shore of the island starting at the position 05°36.01 'N and 103°03 .89'E and along a predetermined transects. This acoustic survey consisted 8 transects, each having a length of 1 nautical miles (1.852 km).The survey been conducted in April and May using research vessel UNIPERTAMA III. Result from analysis using Visual Analyzer program shows that rich distributions were higher along Transect 1, Transect 2, Transect 7 and Transect 8. Result also shows that distribution if fish were higher in coral reef area.
