| 摘 要： | 舟山海区五种藤壶的食性成分分析表明：其胃含物可分为浮游动物、浮游植物、有机碎屑及无机颗粒四类。浮游动物以挠足类为主，浮游植物以硅藻为主。不同大小个体的藤壶摄食偏向有所差别：大个体藤壶较多地摄食大型的烧足类等浮游动物，而小个体藤壶较多地摄食小型的硅藻等浮游植物和有机碎屑。藤壶食物成分种类与其生活海区中的浮游生物种类相一致，并随海区中浮游生物种类和数量变化而变化。通过测定发现，分布于外海的三角藤壶的食物颗粒度明显大于近海虾塘中的纹藤壶的食物颗粒度。

| Abstract: | An account is given of the stomach contents of five species of cirriped, Tetraclita japonica, T. squamosa, Balanus albicostatus, B. amphitrite, B. trigonus, collected from the Zhoushansea waters. The results show there are four basic food categories: zooplankton,phytoplankton, organic or inorganic particulate material. The zooplankton is the major part of the stomach contents of the large individuals. And the phytoplankton is of the small individuals. Theplankton species found in the stomach contents is similar to those found in the sea waters. Andthe stomach contents have a similar species seasonal variation to the sea waters.With a particlesize of the stmach contents of B. trigonus and B. amphitrite, the particle size of the stomachcontents of B.trigonus in the outer sea waters is found bigger than B. amphtrite in the nearcoastal sea waters. |
