The Effect of Fish Finder in Sardine Purse Net Fisheries

Makoto Inoue

Abstract

The fishing rate per month is calculated by Tauti's method, using the statistics of the sardine purse net fisheries at Katagai, Toyoumi, Ôhara in Chiba prefecture; and it is shown that the fishing power of sardine purse net fleets is raised several times as large by means of fish finders. Finally the fishing power of Katagai fleets is estimated.
