| 内容記述 | An influence that artificial disturbance of sandy sea bottom, due to previous exploitation as a sand pit, has on feeding habits of common Japanese conger Conger myriaster and five spot flounder Pseudorhombus pentophthalmus was examined off the coast of Takehara city in Hiroshima Prefecture. Specimens were concurrently collected from an exploited area and a naive one by longline or gill net. In both areas the above two fishes fed mainly on brachyurian crabs (the conger) or mysids (the flounder). However, other preys differed largely between the areas surveyed in the percentage IRI of dietary composition of the fishes; particularly, porcelain crabs were detected only in specimens from the exploited area in either of two fishes. Values of food niche breadth and dietary overlap using the Shannon diversity index (H') and Pianka's index indicated that the two fishes exhibited more diversified utilization of food resource in the exploited area than in the naive one. | |||||
