摘要

印度尼西亚Sungai Batang沼泽的Snakeskin gourami（Trichogaster胸肌）具有很高的商业价值，由于捕鱼对种群的压力很大，但对鱼类生长状况的研究很少。共采样了848条75-200mm（119.14±18.43mm）（TL）和5-132g（29.76±14.76g）的鱼类，以估计其长重关系和条件因素。当地渔民大多使用水平刺网和电捕鱼装置来收集它们。根据研究结果，蛇皮鱼生长不均（b=2.7748-2.8971），表明鱼随着长度的增加而变得细长。雌性的总长度和体重显著高于雄性（P 0.05）。雄性和雌性的平均K值分别为1.64±0.24和1.66±0.21，表明沼泽中的鱼类状况良好。

Morphometric characteristic and condition factor of snakeskin Gourami (Trichogaster pectoralis) from Sungai Batang Swamp, Indonesia

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.
