摘要
记录白鲑的水温(25.36±5.12°C/day)、水深(204.96±110.36cm/month)、透明度(30.91±6.78 cm/day)等物理条件。总硬度、碱度、pH、DO、co2和氨的化学参数分别为146.60±13.36 mg/l、143.30±9.33 mg/l、7.05±0.75、6.03±1.08 mg/l、8.64±0.88 mg/l和0.73±0.31 mg/l。共记录到不同植被54种，浮游植物123种，浮游动物73种。共鉴定出104种鱼类和环节动物(8种)、节肢动物(12种)、软体动物(15种)、两栖动物(8种)、爬行动物(21种)、avis(40种)和哺乳动物(12种)。在脚后跟生态系统中也观察到杀虫剂毒性流出物。关键词:渔业;Eco-Biology;Beel Koshba DOI: 10.3329/ujzru.v28i0.5283 Univ. j. zool。Rajshahi university .

Fisheries eco-biology of beel Koshba in Naogaon District
The physical conditions of Beel Koshba consisting of water temperature (25.36±5.12°C/day), water depth (204.96±110.36cm/month) and water transparency (30.91±6.78 cm/day) were recorded. The chemical parameters of total hardness, alkalinity, pH, DO, CO 2 and ammonia were 146.60±13.36 mg/l, 143.30±9.33 mg/l, 7.05±0.75, 6.03±1.08 mg/l, 8.64±0.88 mg/l and 0.73±0.31 mg/l respectively. A total of 54 species of different vegetations 123 species of phytoplankton and 73 species of zooplankton were recorded from the beel. A total of 104 species of fish and Annelids (8), arthropods (12), molluscs (15), amphibian (8), reptiles (21), avis (40) and mammals (12) were identified. Pesticidal toxic effluents contexts were also observed in the beel ecosystem. Key words: Fisheries; Eco-Biology; Beel Koshba DOI: 10.3329/ujzru.v28i0.5283 Univ. j. zool. Rajshahi Univ.
