Catch-effort analysis based on total catch and CPUE of standard gear (A Microcomputer program)

Abstract

The present paper is a sequel to "Catch-effort Analysis using a microcomputer program" which was published by the SEAFDEC Training Department as the Special Publication No. 1 (TD/SP/1) in May 1983. In the present paper, the author introduce another program for the microcomputer which can be applied to analyze the status of fish stocks as well as its annual change, using the total catch by various gears and CPUE of standard gear. With this program, several important factors of fishing operation and parameters of fish stock can be calculated and tabulated, and seven graphs are generated for quick and easy understanding of the situation under study.
