Abstract |
A study was made of the development of the fertilized eggs of Engraulis enrasicholus ponticus Alex., Scorpaena porcus L., and Crenilabrus tinca L. in sea water containing petroleum, solar oil, and mazut. The different species sensitivity of the fishes to the petroleum products used was found. The damaging effect of these compounds (death of the organisms) was clearly traced down to a concentration of 0.001 ml/liter. The function was expressed that lower concentrations of petroleum, solar oil, and mazut were also proved toxic for the hydrobionts. |
