Apart from sharks there are other fish species that are threatened by overfishing. As overfishing mostly takes place in the oceans, it is difficult to regulate. Oceans are a common good and do not belong to a specific country. Therefore efforts have been done to arrange fishing regulations internationally. In 2000 the FAO's Committee on Fisheries (COFI) adopted an International Plan of Action to regulated fishing. The goal is to prevent and deter illegal fishing and to able to punish offenders.
Freshwater fish- Freshwater fish face different problems. They live in rivers and lakes in areas with large environmental problems, caused by the presence of heavy industry for instance. Many special freshwater fish are found in waters with small areas, because their natural boundaries do not allow them to swim away. It is easier for saltwater fish which live in seas or oceans to find another living area. Because certain types of freshwater fish often live in one place and are unable to leave, water pollution usually has an enormous impact on the fish stock. In Western Europe there has been a lot of attention for water quality in rivers and lakes over the past decades. Industries are subject to strict regulations, and are frequently checked by governmental agencies. Since the 1980s the rivers have tremendously improved, and these days lots of species have been observed which were thought to have disappeared.
Consuming responsibly- Not all fish species are overfished and there is quite a difference in the environmental friendliness of fishing methods. Fishing is based on the market principles of demand and supply. Thus, as a consumer, you can choose to buy the fish not under threat of overfishing over one that is in danger of extinction.
