Abstract

The Batang Asai River in Sarolangun Regency, Jambi, is one of the major rivers with a length of approximately 104 km. Currently, its water quality is declining due to anthropogenic activities such as land clearing, settlements, and mining. This condition threatens the sustainability of fish populations, particularly those from the Cyprinidae family, which are important food fish and sensitive to environmental degradation. However, scientific information regarding the bioecology and spatial distribution of Cyprinidae in this area remains very limited. Therefore, this study is necessary to provide baseline data to support adaptive conservation strategies and fisheries management. The objectives of this research are to identify Cyprinidae species, analyze bioecological aspects (morphometrics, diversity, reproduction, and habitat characteristics), map spatial distribution based on GIS, and determine conservation status according to the IUCN Red List. The study was conducted in August 2025 at three observation stations. The methods used include field surveys, bioecological analysis, and GIS-based spatial mapping. The results showed that 19 species of Cyprinidae were identified with a total of 482 individuals. The fish diversity index value of 2.07 indicates a moderate diversity category, with an evenness value of 0.70 and a dominance value of 0.17. The sex ratio of males to females was 1.9:1, dominated by fish at gonadal maturity stage (GMS) I with 263 individuals. In general, the water quality of the Batang Asai River still supports fish life, and no species were classified as threatened according to the IUCN Red List.

Abstract

Lambak fish (Labiobarbus ocellatus) is a freshwater species of ecological and economic importance in the Batanghari River. Basic biological information, particularly the length–weight relationship, is needed to understand growth characteristics and support sustainable fisheries management. This study aimed to analyze the size distribution and length–weight relationship of lambak fish based on fishermen's catches. Sampling was conducted in August 2025 through direct surveys of daily catches using traditional fishing gears. The length–weight relationship was analyzed using the equation W = aLᵇ. The results showed that the samples consisted of 22 females and 33 males. The total length of females ranged from 117–160 mm and males from 100–157 mm, with weight ranges of 15–36 g and 13–40 g, respectively. The regression coefficient (b) values of 2.1483 for females and 2.2459 for males indicated a negative allometric growth pattern. The coefficients of determination (R²) of 0.6904 for females and 0.501 for males suggested relatively strong to moderate length–weight relationships. This growth pattern reflects the species' biological response to environmental conditions
