Abstract: | The developmental stages of the gonads and the spawning season of the ocean whitefish, Caulolatilus princeps , were determined. Gonad maturation is annual, and the spawning season is prolonged, from late autumn to early spring. From November to March, around 80% of the females were in an advanced mode of gonadal development, and in April most gonads were spent. From May to October the gonads were at rest and preparing for the next spawning season. The gonadosomatic index describes the reproductive activity of the species adequately. |
