Abstract

In the study of different baits and neap/spring tide on the catch composition of hook and line in Sepangar Bay, fish-baited and squid-baited hook and line fishing was being chosen to compare between spring and neap tide in Sepangar Bay. A series of fishing materials was being used to set up four sets of fishing equipments; two for fish-baited hook and line fishing and another two for squid-baited hook and line fishing. The fish bait used is of Decapterus macrosoma (basung) and the squid bait is of Loligo spp (sotong). Fishing operation was being conducted from 8pm to 6am in the spring tides and the neap tides by using UMS Stenella. A total of four spring tides and four neap tides were being chosen from the tide table for this study from July 2007 until November 2007. The objectives of this study are to identify fish species that can be caught using baited hook and line in Sepangar Bay; to determine the different amount of catches between fish and squid-baited hook and line in Sepangar Bay; and to determine the different amount of catches between spring and neap tides using baited hook and line in Sepangar Bay. Species name, local name, length, weight, location of sampling, hook size and bait used are all recorded. A total 138 specimens was caught and there is a highly significant different between the 23 species that was being caught in the amount of catches, average length and weight. Between the baits (fish and squid) and the tides (spring and neap) there is no significant in the number of species caught, amount of catches average weight and length. In this study, the frequently caught species which is more than five fishes caught was being tested statistically between baits (fish and squid) and the tides (spring and neap) for their amount of catches, average weight and length. From all the tests, there show no significant different. This indicates that fishing in Sepangar Bay is not affected by baits used and the tides.
