“…32,33 According to Aminah & Ahmadi, 37 the catchability of the gear is higher during the dry season compared to the wet season, because the fish are being concentrated on the sludge holes or shallow areas and allow for catching them easily. While Kamaruddin et al 73 found the opposite condition, with the reason is the wet season indicates the main feeding and growing time for the fish, 52 and it is very likely to catch the fish. In addition, female climbing perch showed a marked increase in their food intake early in the wet season.…”

“…Contrariwise, some researchers found none of Climbing perch during their sampling periods, for example in Betwa and Gomti Rivers, India. 50 in the Keniam River of Taman Negara Pahang, 51 in River Orogodo of Niger Delta, Nigeria, 52 in Malaysian Waters, 53 in Bukit Merah reservoir, Malaysia, 54 in Lubuk Lampam floodplain of South Sumatera, Indonesia, 55 in Shahrbijar River, Iran, 40 as well as in Narreri Lagoon of Sindh, Pakistan. 43 This is likely attributable to sample size variation, typical fishing gear used, and environmental factors.…”

This study provides scientific evidence on the length-weight relationship, condition factor and growth patterns of the Climbing perch (Anabas testudineus) from Sungai Batang River, Indonesia. The fish were obtained from local fishermen. A total of 156 individuals of A. testudineus consisted of 77 males and 79 females (55-125mm total length and 3-47g weight) were analyzed using SPSS-16 software. There were no statistically significance differences in the total length (TL), body depth (BD), and body weight (W) between male and female, as well as the W/TL and BD/TL ratio values of the fish (P>0.05). Most of total catch falls within the range of 80 and 89mm total length and more than 40% of total catch weighed between 10 and 19g. The W/TL ratio value of A. testudineus in the present study was more or less identical to that of A. testudineus from other different geographical areas. The fish samples were in good condition and grew negatively allometric (b=2.7766-2.8791). Outcomes of this study could be useful for fisheries management and conservation measures in this river.
