| Popis: | Aim. To identify the reasons for the decline of fish stocks in the Caspian sea. Location. The Caspian sea. Methods. When adverse effects of multiple abiotic factors, the other part indicates the important role of fisheries. How fair this point of view will try to answer in this paper. Consider long-term changes in the average water temperature in the Northern Caspian sea. Results. Considered abiotic and biological factors ( prey base) productivity of the Northern Caspian sea could cause catastrophic ( tenfold) reduction of fish stocks. Evidence of this is shown in table. 2 which shows that external factors do not provide a clear correlation with the yield of fish, more important are the internal factors related to the impact of fishing. Main conclusions. You should pay very close attention to human factors and in particular on the volume of catch, location and time fishing and more time to assess how rational our modern craft. |
