We investigated the population ecology of blackthroat seaperch, Doederleinia berycoides, from samples collected in the southern seas of Korea from January to December, 2006. Population ecological parameters included survival rate, the instantaneous coefficient of natural and fishing mortality, and age at first capture. The survival rate (S) of blackthroat seaperch was estimated as 0.4966 using the catch curve method. The instantaneous coefficient of total mortality (Z) was 0.8598/year. The instantaneous coefficient of natural mortality (M) was estimated as 0.4694/year. From the estimates of Z and M, the instantaneous coefficient of fishing mortality (F) was calculated as 0.3904/year. The age at first capture ( $t_c$ ), based on the Pauly method, was 2.87 years. |
