Abstract

Growth is an index of metals influence on a fish. This investigation aimed to determine growth responses of major carps viz. Catla catla, Labeo rohita and Cirrhina mrigala during exposure to sublethal concentration to zinc. The variations among fish age, species, treatment (zinc) of growth parameters viz. weight increment, fork lengths, and condition factor were statistically significant at P<0.01. The control fish age group 90,120,150 and 180 day showed better feed conversion ratio 0.234, 0.168, 0.132 and 0.29 as compared to that of zinc exposed fish which showed range 0.01 to 0.23. Three fish species showed significantly higher amount of zinc in liver than other organs. Labeo rohita showed significantly higher trend for zinc accumulation in body organs than as compared to Cirrhina mrigala and Catla catla. Among body organs; skin, muscle, scales displayed significantly lesser trend for zinc accumulation. It is concluded that metal intoxication significantly reduced the growth of all three fish species and may also show good indicator of metals present in surrounding environment.

锌暴露期间主要鲤鱼的生长性能及鱼体器官的生物蓄积

生长是金属对鱼类影响的一个指标。本研究旨在确定主要鲤鱼，即Catla Catla、Labeo rohita和Cirrhina mrigala在暴露于亚致死浓度的锌时的生长反应。生长参数，即增重、叉长和条件因子，在年龄、物种、处理（锌）之间的差异具有统计学意义，P<0.01。对照鱼90120150和180日龄组的饲料转化率分别为0.234、0.168、0.132和0.29，而锌暴露组的饲料转换率为0.01至0.23。三种鱼类肝脏中的锌含量明显高于其他器官。与Cirrhina mrigala和Catla Catla相比，Labeo rohita在身体器官中的锌积累趋势显著更高。在身体器官之间；皮肤、肌肉和鳞片显示出明显较少的锌积累趋势。结论是，金属中毒显著降低了所有三种鱼类的生长，也可能显示出周围环境中存在金属的良好指标。
