Environmental factors, such as textile waste water, affect fish by interfering its reproduction. This study was conducted to examine reproductive performance of fish inhabiting a river that receive batik waste. The fish samples were collected in 5 stations representing upstream area, effluent disposal area, and downstream area. Sex ratio, Gonado Somatic Index (GSI), Hepatosomatic Index (HSI) of female and male was examined, and physicochemical water parameters of each station were measured. Ten species of 8 families were captured. Anabas testudinaeus (n=101), Trichogaster trichopterus (n=310), Mugil sp (n=3), Scatophagus argus (n=8), Valamugil speigleri (n=11), Channa striata (n=2), Bagrus nemurus (n=1), Laiognathus fasciatus (n=2), Oreochromis niloticus (n=1), O. mossambicus (n=5). Mugil sp, V. speigleri, and L. fasciatus were juvenile, and found at the downstream area. The GSI of female and male A. testudinaeus were 0.31-5.52% and 0.34-3.32%; the HSI was 0.77-2.01% and 0.68-1.79%. The GSI of female and male T. trichopterus were 0.12-7.9% and nd-3,7%; the HSI was 0.77-2.17% and 0.6-2.0%. The BOD level ranged from 13.81 6.13 to 47.58 32.59 mg.L⁻¹, COD was between 190 80 and 435 196 mg.L⁻¹, DO was from 0 to 1.37 1.62 mg.L⁻¹, level phenol ranged from 0.50 0.34 to 4.20 1.6 g.L⁻¹. Fish of Meduri River were reproductively active but only those resistant to low water quality reproduced successfully.

环境因素，如纺织废水，通过干扰其繁殖来影响鱼类。进行这项研究是为了检查生活在接受蜡染废料的河流中的鱼类的繁殖性能。鱼样在上游区域、污水处理区域和下游区域的 5 个站点采集。检测男女性别比、性腺体指数（GSI）、肝体指数（HSI），测定各站水理化参数。捕获了8科10种。Anabas testudinaeus (n=101), Trichogaster trichopterus (n=310), Mugil sp (n=3), Scatophagus argus (n=8), Valamugil speigleri (n=11), Channa striata(n=2), Bagrus nemurus (n=1), Laiognathus fasciatus (n=2), Oreochromis niloticus (n=1), O. mossambicus (n=5)。Mugil sp、V. speigleri和L. fasciatus为幼体，发现于下游区域。雌性和雄性A. testudinaeus的GSI分别为0.31-5.52%和0.34-3.32%；恒指分别为0.77-2.01%和0.68-1.79%。雌性和雄性T. trichopterus的 GSI分别为 0.12-7.9% 和 nd-3.7%；恒指分别为0.77-2.17%和0.6-2.0%。BOD水平范围从13.81 6.13到47.58 32.59 mg.L ^-1，COD在190 80和435 196 mg.L ^-1之间，DO从0到1.37 1.62 mg.L^-1，苯酚含量范围为0.50 0.34 至4.20 1.6 gL ^-1。梅杜里河的鱼繁殖活跃，但只有对低水质有抵抗力的鱼才能成功繁殖。
