摘要
暗鳃弹涂鱼可变眼炎是戈比鱼科的一员,是越南湄公河三角洲(MD)的一种潜在的水族馆宠物;然而,关于其进食习惯和强度的数据有限。因此,本研究旨在评估可变眼炎的相对肠道长度(RGL)和胃肠体细胞指数(GI),以确定这种弹涂鱼的进食习惯和强度,以及它在性别、大小、季节、地点及其相互作用方面的变化。从2022年1月到2022年12月,每月在四个地点采集一千一百七十个弹涂鱼样本:Duyen Hai Tra Vinh、Tran De Soc Trang、Hoa Binh Bac Lieu和Dam Doi Ca Mau。结果表明,栓眼鱼为肉食性鱼类,平均RGL值为0.52±0.01SE(<1)。此外,该物种的RGL各不相同,取决于大小、采样地点、季节以及大小和季节与地点的相互作用。弹涂鱼的GI为4.27±0.29 SE,表明其进食强度属于中等类别,随大小和地点而变化,但不随性别、季节和相互作用而变化。这些结果补充了关于其食性和强度的新知识,为在马里兰州研究栓眼菌的水产养殖奠定了基础。
Feeding habit and intensity of Periophthalmus variabilis caught from some coastal provinces in the Mekong Delta, Vietnam
Dusky-gilled mudskipper Periophthalmus variabilis, a member of the family Gobiidae, is a potential aquarium pet in the Mekong Delta (MD), Vietnam; however, data on its feeding habit and intensity has been limited. Therefore, this study aims to evaluate the relative gut length (RGL) and gastro-somatic index (GI) of Periophthalmus variabilis in order to determine the feeding habit and intensity of this mudskipper and its variation regarding sex, size, season, site, and their interaction. One thousand one hundred seventy mudskipper samples were collected monthly in four locations: Duyen Hai-Tra Vinh, Tran De-Soc Trang, Hoa Binh-Bac Lieu, and Dam Doi-Ca Mau from January 2022 to December 2022. The analysis showed that Periophthalmus variabilis was a carnivorous fish with an average RGL value of 0.52±0.01 SE (<1). In addition, the RGL of this species varied and depended on size, sampling site, season, and the interaction of both size and season with locations. The GI of the mudskipper was 4.27±0.29 SE, indicating that its feeding intensity belonged to the moderate category and varied with size and site but not sex, season, and interactions. These results supplement novel knowledge on its feeding habit and intensity, a basis for researching the aquaculture of Periophthalmus variabilis in MD.
