A survey of fishes in Shahjahanpur in different aquatic habitats revealed 35 indigenous fish species. Out of 35 fish species, 24 were found feeding on mosquito larvae of which 6 species, viz. Chela bacaila, Puntius stigma, Rasbora daniconius, Esomus danricus, Colisa fasciatus and Danio sp., had good larvivorous potential. Most of the fish species preferred to feed on III and IV instar larvae. In the presence of planktonic food, the consumption capacity of fishes for mosquito larvae was lesser on third day (D3) of observation than on first day (D1). The difference in the consumption of mosquito larvae between D1 and D3 was significant (P < 0.01). Similarly, difference in the feeding capacity of fishes in the months of September and January was highly significant (P < 0.001). But there was no seasonal variation in the preference of instar-wise consumption. Indigenous fish species such as C. fasciatus, E. danricus, P. stigma, R. daniconius and Danio sp. could therefore play a significant role in controlling mosquito breeding in this area.
对沙贾汉布尔不同水生栖息地的鱼类调查发现了35种本地鱼类。在这35种鱼类中，有24种以蚊子幼虫为食，其中6种，即印度细须鲃、斑尾鲃、丹氏波鱼、长麦穗鱼、条纹斗鱼和斑马鱼属，具有良好的食蚊潜力。大多数鱼类喜欢取食三龄和四龄幼虫。在有浮游食物的情况下，鱼类在观察的第三天（D3）对蚊子幼虫的摄食量比第一天（D1）少。D1和D3之间蚊子幼虫摄食量的差异显著（P < 0.01）。同样，9月和1月鱼类摄食能力的差异非常显著（P < 0.001）。但在按龄期摄食偏好方面没有季节性变化。因此，条纹斗鱼、长麦穗鱼、斑尾鲃、丹氏波鱼和斑马鱼属等本地鱼类在控制该地区蚊子繁殖方面可以发挥重要作用。
