Abstract

Clarias meladerma Bleeker, 1846 is one of the native species in Indonesia. Aek Silom Lom is one of the habitats of catfish moma (C. meladerma) located in Labuhanbatu district. The study was conducted to analyze the long-weight relationship and the condition factors of catfish moma (C. meladerma) that live in Aek Silom Lom. Sample collected from October- December 2021. Sample was taken by angler. This weight length relationship is calculated using the linear allometric model (LAM), while the condition factor is calculated using the fulton formula (K) and relative weight (Wr). The growth pattern of catfish moma (C. meladerma) in Aek Silom lom is allometric negative with a value of b 0.99 (b<3), this means that the growth of the fish's body length is faster than the body weight. The fulton coefficient (K) is between 14,889 -17.1292 and the relative weight coefficient (wr) is in the range of 97.32805-100.0745, indicating that the condition of the catfish population (C. meladerma) is in balance and the water conditions of Aek Silom Lom can support the life of the catfish moma (C. meladerma)

Abstract

This study aims to determine about length-weight relationship and condition factors of Channa striata in Tanjung Haloban village, Bilah Hilir District, Labuhanbatu Regency. The study was conducted from October to December 2021. Sampling of snakehead fish (C. striata) had done in Tanjung Haloban village. Measurement of the length and weight of snakehead fish (C. striata) was carried out in the ecology laboratory of the Faculty of Teacher Training and Education, Universitas Labuhanbatu. The tools used in this study among others rods, ruler, scales, calipers, buckets. Sampling is carried out for three months with fishing gear. The length-weight relationship can be analyzed using the linear allometric model (LAM) equation. Based on the results of the analysis of the relationship in the length of the snakehead fish weight (C. striata) shows that the results of measuring the length of the snakehead fish weight can be known that male and female snakehead fish have a negative alomatric pattern with a value of b<3, while the condition factor calculated with relative weight (WR) 100.58 and the fulton condition factor (K) 0.85 is close to 1 which means the condition of the swamp waters of the snakehead fish habitat is in a balance state.
