2010∼2012년 참조기 유자망어업의 어획물의 연령조성자료를 사용하여 참조기의 자원생태학적 파라미터를 추정하였다. 추정된 자원생태학적 파라미터는 생잔율, 순간자연사망계수, 순간어획사망계수 및 어구가입연령이다. 생잔율은 어획물곡선법, Jackson 방법, Heincke 방법, 평균연령이용법, Chapman and Robson 방법, 그리고 Beverton and Holt 방법으로 0.10∼0.39의 범위로 추정되었다. 여러 방법 중 어획물곡선법은 다른 방법에 비하여 평방편차합이 적고, 상관계수와 통계학적 유의수준이 높았다. 순간자연사망계수는 Alverson and Carney 방법, Alagaraja 방법, Pauly 방법과 Zhang and Megrey 방법으로 추정하였다. Alverson and Carney 방법에 의해 추정된 순간자연사망계수가 가장 적합한 것으로 판단된다. 순간어획사망계수는 순간전사망계수에서 뺀 값으로, 평방편차합이 적고 상관계수가 높은 어획물곡선법으로 추정된 생잔율을 순간전사망계수로 전환하여 추정하였다. 이 경우 순간전사망계수는 1.611/년이며, 순간어획사망계수는 1.153이었다. 참조기 유자망어업으로 어획된 참조기의 어획개시체장 (Lc)은 19.1cm이며, 어획개시연령 (tc)은 1.303세이었다.
Abstract
Estimations on population ecological parameters of the small yellow croaker, Larimichthy polyactis in Korean waters, were calculated using catch data based on coastal and offshore drift gillnet fishery and biological data from 2010 to 2012. The population ecological parameters included survival rate, instantaneous coefficient of natural and fishing mortality and age/length at first capture. The survival rate (S) of the small yellow croaker was estimated to be 0.20 from catch curve method. The instantaneous coefficient of natural mortality (M) was estimated to be 0.46/year with Alverson and Carney method. The instantaneous coefficient of total mortality (Z) was 1.611/year, used to be transformed the survival rate and the instantaneous coefficient of fishing mortality (F) were 1.153/year. The length at first capture (Lc) was 19.1cm by Pauly method, and the age at first capture (tc) was 1.303 years of the small yellow croaker by the coastal and offshore drift gillnet fishery.
