Abstract
- This study was performed to estimate biomass and provide management guidance through population ecological characteristics, including growth parameters, survival rate, instantaneous coefficients of natural and fish mortalities, and age at first capture of the purple clam, Saxidomus purpuratus in the adjacent waters of Geoje Island in Korea. The von Bertalanffy growth parameters were SH=88.91mm, K=0.248, T0=-0.529, and S=0.537. The natural mortality(M) was estimated to be 0.212/year and fishing mortality (F), 0.410/year for the purple clam. The age at first capture(Tc) was estimated as 2.45 years. An yield per recruit analysis showed that the current yield per recruit was about 48.16 g with F=0.410/year. The current biomass of the purple clam in the study area was estimated to be 24.265 MT, and the acceptable biological catch(ABC) was estimated under various harvest strategies based on F0.1, Fmax and F40%.
