摘要

对来自塞浦路斯的104只黄斑金鸡(Torquigener flavimaculosus)进行胃内容物检测。分析表明，它是一种杂食性物种，偏爱捕食动物，特别是行动能力有限的无脊椎动物(甲壳类、软体动物、棘皮动物)。长度-体重关系的研究表明，两性均呈负异速生长。似乎它对无脊椎动物的偏好，其组织中高浓度河豚毒素的高毒性以及其他一些生物学特性强化了它作为侵入性物种的特征，应该针对这些物种设计监测行动。

Shedding light on the diet of the Lessepsian yellowspotted puffer Torquigener flavimaculosus Hardy and Randall, 1983 in the Eastern Mediterranean

The stomach contents of 104 individuals of Torquigener flavimaculosus from Cyprus were examined. The analysis revealed that it is an omnivorous species with a preference to animal prey, especially invertebrates with limited mobility (crustaceans, molluscs, echinoderms). The study of the length-weight relationship indicated a negative allometric growth for both sexes. It seems that its preference to consume invertebrates, its high toxicity due to high concentrations of tetrodotoxin in its tissues and some other biological characteristic reinforce its characterisation as invasive and monitoring actions should be designed for such species.
