摘要
采用剪鳍标记法 ,现场模拟测定了钻井噪声与振动对鲤鱼生长的影响。研究结果表明 ,钻井噪声与振动对鲤鱼生长有显著影响 ,其临界等效噪声级和振动级约为 83.9d B和 89.7d B,影响域径约为 9m;污染持续时间、体重和群居行为等生态因素 ,能显著改变钻井噪声与振动对鲤鱼生长的污染效应 ;由于在污染消失后鲤鱼生长率能迅速恢复 ,这说明钻井噪声与振动对鲤鱼的影响是可逆的 ,并未产生器质性损伤。因此 ,用非听觉系统激起反应解释钻井噪声与振动对鲤鱼的影响机制可能是合理的。
Effect of drilling noise and vibration pollution on growth of carp( Cyprinus carpio) was studied by cut fin marking method on petroleum reconnoitering spot. The method is considered to be an appropriate one in simulating experiment of fishs growth in situ, because its operation is simple and more efficiency, data may be obtained at the same conditions. The results showed that effect of the pollution on carps growth was remarkable, of which critical equivalent noise level( NL eq) and vibration level (VL eq) was about 90dB and 97dB and affecting semidiameter 9m, and could be changed by the polluting duration, body weight and social behavior of carp. The experiment, in which carps growth rate got rapid resume after the pollution disappeared, explained that the effect didnt damage the fish bodys apparatus and was reversible. Therefore, it may be reasonable that the affecting mechanism could be explained by activating response of non hearing system.
