On the Growth of Population of Fish Newly Liberated into a Lake

Abstract

A method for estimating the ultimate population of adult fish, when the equilibrium between catch and recruitment due to liberation is attained, was developed. The method was applied to fishing of Himemasu (Oncorhynclaus adonis (J_ORDAN et M_C G_REGOR)) in Lake Towada, with slight modification, which was inevitable owing to the lack of complete statistics.
