| 内容記述 | The general ecology of young frog flounder, Pleuronichthys cornutus, in their nurserygrounds was studied in the waters of the San-in district and the western Wakasa Bay, the Japan Sea. The growth rate of 0-age fish is rather rapid throughout spring and summer, but becomes slower during autumn and winter. 0-age fish reach a mean length of about il cm by the end of their first year. The main populations were found in the shallower waters in April, and from May to August they show wide ranges in a vertical distribution. During the period of this survey, only one example of predation on young frog flounder was observed. The conger eel was observed to be the active predator. Analyses of the stomach contents showed that food items included polychaeta and amphipods. It is necessary to investigate the significance of shallow water areas in relation to the management of the resources of economically important fishes. Many such fishes live in shallow waters during their juvenile and young stages. Especially, the young of various commercial flatfishes inhabit shallow waters and such areas have been known as their nursery grounds. Little is known about the biology of the young frog flounder, Pleuronichthys cornutus (TEMMINCK et SCHLEGEL), although its importance as commercial species in Japan. The present paper is one part of general study on the early life history of flatfishes and deal with growth, distribution, and feeding habits during the first (0-group) year of life of the frog flounder. | |||||||||||||||||

| 内容記述 | 日本海の山陰沿岸において,メイタガレイ幼稚魚の成長,分布域の変化,食性,被捕食について調査した.成育場におけるメイタガレイ幼稚魚は,春と夏には急速に成長し,秋以降は緩やかな成長をする.また,成長にともなって成育場における分布水深は,深い海域に広がるが,秋にはさらに深い水深100m付近に移動すると推定された.幼稚魚の餌生物は,体長2cmから10cmでは多毛類が主で,端脚類がこれに次ぐ.量的には体長3cmから6cmで急激に摂食量が増す.山陰沿岸の同海域にはヒラメやムシガレイなどの異体類が成育場を形成し,メイタガレイと同様の分布域の拡大,深所への移動を行なうが,食性は甲殼類食である. | |||||||||||||||||
