Abstract

Many freshwater ecosystems are contaminated with heavy metals released by municipal wastewater, cultivation and factory wastewater. The aim of the study was to evaluate the negative impact of metal pollution on the fish reproductive system. It was performed using the gonadal histopathology, hepatosomatic index (HSI), and gonadosomatic index (GSI) of three fish species, Capoeta damascina, Squalius semae and Alburnus sellal inhabiting in Karasu River (Erzurum, Turkey) contaminated by various anthropogenic activities. The highest GSI values were determined for each sex according to the seasons, and lower GSI values were observed in polluted stations in all three species. It was observed that HSI values in fish varied significantly from station to station. In addition, an increase in ovarian and testicular lesions (degeneration in oocyte and spermatocytes, atresia, congestion, infiltration, edema, vascular hypertrophy, fibrosis) was detected in the polluted areas. The results clearly showed that the metal pollution in the river adversely affected the reproductive system of the fish species living in the river.
从受人类活动影响的河流中采集的鲤科鱼类的性腺健康状况
许多淡水生态系统都受到城市污水、养殖和工厂废水释放的重金属污染。本研究旨在评估金属污染对鱼类生殖系统的负面影响。研究利用性腺组织病理学、肝体指数(HSI)和性腺指数(GSI)对栖息在受各种人为活动污染的卡拉苏河(土耳其埃尔祖鲁姆)中的三种鱼类--大马士革鲶(Capoeta damascina)、鱿鱼(Squalius semae)和鲑鱼(Alburnus sellal)进行了检测。根据季节的不同,每种雌雄鱿鱼的 GSI 值最高,而在受污染的水域,所有三种鱿鱼的 GSI 值都较低。据观察,不同站点的鱼类 HSI 值差异显著。此外,在污染区还发现卵巢和睾丸病变(卵母细胞和精母细胞变性、闭锁、充血、浸润、水肿、血管肥大、纤维化)增加。结果清楚地表明,河流中的金属污染对生活在河流中的鱼类的生殖系统产生了不利影响。
