Abstract

Research of early life history of fish is very important for efficient resources management of Cod that has strong homing instinct, because survival rate of fish eggs and larvae is most important factor that determine the strength of recruitment. Pre and post larval stage samples were collected at 1~6 stations located in Jinhae Bay. Pacific cod comes into Jinhae Bay spawned mainly the mouth of Jinhae Bay, pre-larval stage hatching from its eggs and growing distributed mainly the mouth and inside of there. And post-larval stage having the ability to swim and moving to bottom distributed mainly from the inside to the offside, south of Gaduk island, of there.uitment.
