The Statistical Study on the Fluctuation of the Catch of Plccoglosus altivelis with reference to the Rainfall

[摘要] As a whole, the bad catch may be resulted by the abundance of rainfall during the anadromous period. The above relation on April and May at Tohoku-and Kwanto-district is recognized more clearly than that on the other months, and on February and March at Sikoku-and Kyushu-district. The great amount of the precipitation in the hatching period has a tendency to give the good catch of the fish in the next year.
