Abstract

Glossogobius aureus is one of the economy fish species belonging to the family Gobiidae. Little is known about the fish’ relative gut length (RGL) and Gastro-somatic index (GI), which are used to determine the feeding habit and intensity of fish. Therefore, this research aims to provide additional data about RGL and GI of Glossogobius aureus by sex, body size, season and sampling location in Me Kong Delta. Fish samples were collected monthly using gill nets in Cai Rang, Long Phu, Hoa Binh and Dam Doi from January to December 2020. Intestinal analysis of 742 fish samples showed that Glossogobius aureus was a canivore species with RGL = 0.393 < 1. In addition, the variation of the RGL of this species depended on size, sampling site and the interaction of both size and season with locations. Meanwhile, season, interaction between sex with season, size with season, and sex with location did not affect RGL. The intensity of the female was similar to that of the male; the intensity of the immature was similar to that of the mature. Catching intensity was influenced by size and interaction between season and location; however, it was not influenced by the interaction between sex and location, size with location and size with season. The findings can be served for future culturing study on fish species.
