Abstract
A study was made to find out a new method of calculating the survival rate of a fish population from length composition and growth equation. 1. In the steady state of the fish population, let the total mortality rate be z, the age of complete recruitment a, the oldest age in the catch b and the average between the age of complete recruitment and the oldest age in the catch Ut, then we have
어획대상 자원에 있어서 감소계수를 z, 완전가입 년령을 a, 최고년령을 b라 할 때 체장조성과 성장곡선식을 이용해서 감소계수 z를 구하는 수학적 모형을 설정하여 고등어와 전갱이의 생잔율을 추도한 결과를 요약하면 다음과 같다. 1. 평균년령을
