摘要

黑斑紅鱸(Sciaenops ocellatus Linnaeus)為引進臺灣之外來魚種，本研究旨在瞭解此魚之食性與其他生物間的關係，首先乃利用實驗生態學的方法，探討此魚稚魚期之食性好惡。此次採用之八種餌料中，海（青）虫是其最嗜食的食物，其他依序為牡蠣、小管、鯖魚、鮑魚、蟹、海參及南極蝦。此項食性之嗜好之表現其實是相對的，乃視食物群中組成之成份而定；當海虫與其他餌料同時出現時，稚魚會選擇海虫而排斥其他食物。

The red drum, Sciaenops ocellatus Linnaeus, is an exotic aquaculture species in Taiwan. To understand its relations with the organisms in its food complex is the concern of this study, which applied an approach of experimental ecology to determine its food preference and avoidance. For eight food items studied, nereid polychaete (the so-called ragworm) was the most preferred one, and then followed by oyster meat, small squid, mackerel, abalone meat, crab, sea cucumber, and krill. The order of food preference or avoidance is rather relative and dependent on what is present in the food complex. When there were ragworm with other food items, the juvenile red drum had a special preference for the worm and avoided all others. This preference probably is due to the quality of the food item.
