The Japanese sea-bass, Lateolabrax japonicus, after hatched out in December or January in Sendai Bay, grows rapidly in Matsushima Bay attaining to 200mm, 135g at the end of the first year and to 300mm, 410g at the second year of life. This rate of growth is approximately eightfold in weight as much as that of Sebastes inermis, the most common fish in the Zostera area of Matsushima Bay. However, considering from the results of the feeding experiments, the fish in nature does not usually give full scope to its growth potential and would grow more rapidly provided with more sufficient food supply even under the unchanged conditions of non-biological circumstances.
