污染最严重的布里甘加河中的鱼类、渔具和工艺品都是有害的。2012年12月至2013年11月，共记录鱼类56种，隶属于9目20科。鲤形目是最主要的目，有18种（32%）。最高的鱼类多样性记录在季风季节，冬季最低。多样性方差最大值（7.616 ± 2.76Sd）出现在季风季节，有56个种（220个个体）。还观察到两类（主动和被动）12种不同类型的渔具和两种类型的船只在研究区域捕鱼。2013年8月录得的鱼类种类最多（n = 56），4月及5月最少（n = 3）。水深与鱼类数量（r = 0.74）和捕捞活动（r = 0.96）之间存在很强的相关性。Bangladesh J.

Fish species, fishing gear and crafts in the most polluted river Buriganga were inventorial. During December, 2012 to November, 2013, a total of 56 fish species belonging to 20 families and 9 orders were recorded. Cypriniformes observed to be the most dominant order with 18 species (32%). The highest fish diversity was recorded during monsoon season, and lowest during winter. Maximum diversity variance (7.616 ± 2.76 Sd) observed in the monsoon season for 56 species (220 individuals). Also 12 different types of gears of two categories (active and passive) and two types of crafts were observed to be used for fishing in the study area. The highest number of species of fishes (n = 56) recorded in August and lowest (n = 3) in April and May 2013. Strong correlation between water depth and number of fish species (r = 0.74) and fishing activities (r = 0.96) was observed. Bangladesh J. Zool. 45 (1): 11-26, 2017
