Catch-Effort Analysis using a Microcomputer Program.
In the present paper, the author introduces two original programs for the micro-computer which stocks as well as their annual changes, using catch and fishing effort data "by statistical areas". With these programs, several important factors of fishing operation and parameters of fish stock are calculated and tabulated (Program No. 600-A). Also, seven graphs and four histograms are generated for quick and easy understanding of situations under study (Program No. 600-B).
