Abstract

Line fishing has an old history in Malaysia and become more popular even until now. It is one of the most important sources in fishery production. So this study is important in the development of fishery activity. In this study, sample data about the fish species, each species' common name, length and weight in Sepanggar Bay area provided. The spring and neap tides are action by gravitational forces of the moon andthe sun both contribute to the tides. By the different sea water level, water current, and many other factors in the spring and neap tides, fishing activity is influence by the tide change in the Sepanggar Bay area. After the data analyses, the result show the number of catches is more when the fishing operation in the spring tide. A total of 154 fishes, 28 species, 19 families caught in the eight times sampling during 29th July 2007 until 15th November 2007. The number of catches, average weight and average length between species also has highly difference. Beside the affect from the spring and neap tides in the fishing operation, compare the catches between hook size 12 and 15 is another objective in this study. But the data analyses show there is no difference between hook size 12 and 15 using fish-baited hook and line in Sepanggar Bay
