| Abstract |
2004年5月6自に瀬戸内海の広島湾で,体側の前後でツートンカラー模様を持つクロダイAcanthopagrus schlegeli 1個体を発見した.本個体の全長は22cmで,体の前半部は通常の明灰銀色だが,後半部は異常な黒灰色を呈し,保護色は失われていた.本体色パターンは左右両側で一致していた.本報は,クロダイのみならずタイ科での本体色異常に関する初めての記録である.
On May 6, 2004, a black porgy, Acanthopagrus schlegeli, 22 cm total length, which has a two -tone bilateral color pattern, was observed in Hiroshima Bay. The anterior half part of the body showed the usual light grayish-silver color, while the posterior half was dark gray. Consequently it lost its protective coloration. The division of two colors on the both sides completely corresponded with each other. This is the first report about the anomalous coloration not only in A. schlegeli but in sparid fishes.
