Abstract

Tamblingan Lake is the smallest lake in Bali and plays a vital role in the surrounding environment. The fish community in Tamblingan Lake includes the bonylip barb (Osteochilus vittatus), spotted barb (Barbodes binotatus), silver rasbora (Rasbora argyrotaenia), convict cichlid (Amatitlania nigrofasciata), Nile tilapia (Oreochromis niloticus), and green swordtail (Xiphophorus hellerii). However, information on the diet of the fish community is not yet available. This study aims to analyze and describe the dietary aspects of the fish community in Tamblingan Lake. The research was conducted at six stations from August to September 2024 using gill nets with mesh sizes of 1.0, 1.5, and 2.0 inches. A total of 152 fish samples were analyzed. The results showed 57 types of food, including phytoplankton (5 classes), zooplankton (5 classes), macrophytes, and insects (1 class each). Phytoplankton was consumed by bonylip barb (5 classes), spotted barb (5 classes), silver rasbora (5 classes), convict cichlid (4 classes), Nile tilapia (5 classes), and green swordtail (5 classes). Zooplankton was consumed by bonylip barb (2 classes), spotted barb (3 classes), silver rasbora (2 classes), convict cichlid (1 class), Nile tilapia (2 classes), and green swordtail (3 classes). Macrophytes were consumed by silver rasbora and green swordtail (1 class each). Insects were consumed by silver rasbora, convict cichlid, and green swordtail (1 class each). This information on fish diet can serve as a basis for developing fish resource management strategies in Tamblingan Lake.
