摘要：This research studied the food habits and trophic level of A. testudineus in a floodplain lake, Lake Semayang, East Kalimantan. The lake has characteristics of both swamp and lake habitats. The research was conducted from February 2017 until January 2018. During the study, 558 samples of Anabas testudineus were analyzed. The Index of Stomach Content (ISC) in the swamp habitats ranged from 4.32 - 39.59%, with an average of 19.35%, while in the lake habitat ranged from 3.68 - 38.46% with an average of 16.03%. Index of Preponderance (IP) value showed the dominant food item in the fish stomach is animal (62.58 - 79.66%), plants (25.18 - 42%), and undetectable food (≥ 5%). Based on the type and composition of the food, A. testudineus can be classified as omnivorous more inclined to carnivorous. The trophic level of this species changes along with increasing size length.
