Abstract
The Snakeskin gourami ( Trichogaster pectoralis ) from Sungai Batang swamp, Indonesia has high commercial value and high pressure on population due to fishing, while the fish growth condition is poorly studied. A total of 848 fish ranging 75-200mm (119.14±18.43mm) (TL) and 5-132g (29.76±14.76g) were sampled to estimate its length-weight relationship and condition factors. Local fishermen mostly collected them using horizontal gill-net and also electrofishing device. Based on the results, the Snakeskin gourami grow allometrically ( b =2.7748-2.8971), indicating that fish becomes slender as the length increases. Total length and weight of female were significantly higher than those of male ( P 0.05). The mean K values for male and female were 1.64±0.24 and 1.66±0.21, respectively, indicating that fish in the swamp is in good condition.
期刊介绍：
Iranian Journal of Ichthyology (IJI) is a peer-reviewed journal for publication of high quality papers on any aspect of ichthyology and will be published 4 times a year by the Iranian Society of Ichthyology (http://www.isi-org.ir). The journal welcomes the submission of manuscripts that meets the general criteria of significance and scientific excellence, and will publish original scientific articles in the fields of ichthyology. The editors welcome the submission of original manuscripts including Research Articles, Short communications, and Views & News. Review papers by distinguished authors and Special Issues will also be considered. It is our aim to provide the international scientific community with an efficiently published journal, meeting high scientific and technical standards. Scopes of Iranian Journal of Ichthyology includes: Systematics, taxonomy, morphology, anatomy, biogeography, biodiversity, conservation, ecology and general biology of fishes (reproduction, food and feeding habits, age and growth, population dynamics, etc.). Papers on freshwater, brackish, marine and fossil fishes will be considered.
