Abstract

This research looks at the types and diversity of fish, dominance index, evenness index, and richness index of fish species found in the Batang Bungo River, Jambi Province, Indonesia. This research was conducted from March to May 2022 at III stations. Station I Dusun Buat, station II Dusun Rantau Pandan, and station III Dusun Rantau Duku. The fishing equipment used are gillnets, nets, traps, shooting, longline fishing, and fixed fishing using local fishermen. The types of fish caught were 18 species in 5 orders, 14 genera from the Cypriniformes order, one genus from the Labyrinthici order, one genus from the Perciformes order, one genus from the Siluriformes order, and one genus from the tetraodontiformes order, the total number caught was 505 fish. The fish species diversity index (Hˈ) is in the medium category with a value of 2,576, the species evenness index (E) 0.891, the dominance index (C') 0.095, and the species richness (R) 2.731.

Abstract

The bilih fish (Mystacoleucus padangensis Blkr) is an endemic species in Lake Singkarak, holding significant economic value. However, its population has drastically declined over the past few decades and is currently classified as 'vulnerable'. One of the crucial factors in the successful cultivation of bilih fish is the provision of appropriate feed during the early larval stages, particularly after the depletion of endogenous yolk reserves. This study aims to examine the exogenous feeding phase in bilih fish larvae after the endogenous food supply has been exhausted, which marks the stage when the larvae must begin to rely on external feed for survival and growth. The study employed a Completely Randomized Design of three treatments with four replications each. Treatment A involved feeding Chlorella sp. (days 3-10), followed by Artemia (days 10-20); Treatment B involved Chlorella sp. (days 3-10), followed by artificial feed (days 10-15) and Artemia (days 15-20); and Treatment C involved artificial feed (days 3-10), followed by Artemia (days 10-20). The larvae were reared in tarpaulin tanks with a water volume of 125 L and a stocking density of 2,000±85 individuals, and they were fed to satiation twice a day (morning and evening) for 20 days. Data were analyzed using One-way ANOVA with the IBM SPPS Statistics 25 program. The results showed that the provision of different exogenous feed compositions had no significant effect (P˃0.05) on absolute length growth and survival of bilih fish larvae (Mystacoleucus padangensis Blkr). Treatment B produced the best survival (31.75 ± 1.70%) and absolute length growth (3.67 ± 0.21 mm). The results of the water quality parameters show an average temperature of 28±1.2oC, pH 28±1.2, dissolved oxygen 5.6±0.78 mg/l.Keywords: Absolute Length Growth; Bilih Fish Larva; Diet Type; Feed Composition; Survival Rate
