Annual life period of adult righteye flounders limanda herzensteini and limanda yokohamae in mutsu bay japan



Annual life period of adult righteye flounders limanda herzensteini and limanda yokohamae in mutsu bay japan



Nippon Suisan Gakkaishi 49(5): 663-670



In order to elucidate the annual period of adult L. herzensteini and L. yokohamae in Mutsu Bay, Aomori prefecture, the seasonal changes in several physiological conditions, i.e., the gonadsomatic index, hepatosomatic index and condition factor of samples chiefly obtained with the trawl nets from April 1978 to Nov. 1981 were examined. Feeding intensity was investigated from stomach contents, weight index and feeding frequency per day. The annual life period of L. yokohamae was divided roughly into the following 4 stages: spawning (fasting), wintering (inactive feeding), recovering (active feeding) and maturing (inactive feeding). That of L. herzensteini was divided into the 3 periods without the wintering. Although in winter they escaped the cold water (2-3.degree. C) and were concentrated in the area near the entrance of bay, L. yokohamae hardly ingested food and the feeding activity of L. herzensteini was also inactive probably on account of low temperature and inadequate food supply. In spring both species commenced active feeding, having 2 feeding periods per day. Their food intake rates gradually declined after summer (1 feeding peak) when hepatosomatic index and condition factor attained peak in the seasonal cycle, irrespective of temperature, food supply and other external factors. Such seasonal changes in feeding intensity are closely connected with the degree of food requirement in relation to their fat contents.
