Abstract
To investigate the relationship between total length and fecundity of Pacific cod Gadus macrocephalus in Jinhae Bay, 45 individuals were sampled during the spawning period from Dec 2008 to Feb 2009. Fecundity ranged from 560,000 to 5,200,000 eggs for fish ranging from 64.0 cm to 74.0 cm in total length. The relationship between total length (TL) and fecundity (F) was F=103,273TL-5,124,302 and fecundity in Pacific cod from this study was correlated with total length. Average fecundity decreased from 2,620,000 eggs in early-spawning period to 1,650,000 eggs in late-spawning period. The wide range of relative fecundity at the same body size indicates that the timing of the spawning migration of Pacific cod in Jinhae Bay could be related to fecundity.
