Stop Overfishing

Millions of people enjoy fishing as it is a very fascinating activity. Many fishermen could spend hours by this activity without any notion of time. The real fisherman does not care about a beautiful beach nearby, nor does he care too much about good weather. Moreover it is not that important for him how much fish he catches for he enjoys the process much more than the result.

Unfortunately in the last decades mankind has changed to a great extent and there are numerous new hobbies that directly or indirectly compete with fishing. One does not meet real fishermen as often as before while at the same time there are more and more people who relentlessly kill large amounts of fish with the help of big nets and other illegal fishing tools. The danger of overfishing lies in that some marine organisms don’t reproduce and replenish the fish stock rapidly to compensate for the amounts lost due to overfishing.

Sharks are among the species mostly affected by overfishing. Tremendous decline in shark population has led to huge damage to world oceans because sharks play one of the key roles in maintaining the balance and health of our oceans. The factor that makes sharks so vulnerable to overfishing is that they reproduce very slowly.

Therefore, overfishing has become a real problem lately and it would not be an exaggeration to say that it leads to catastrophic environmental consequences.

One could realize the real scale of the overfishing problem considering that over 25% of all the world’s fish stocks are either overexploited or depleted. Another 52% is fully exploited and in imminent danger of overexploitation and collapse. Therefore a total of little less than 80% of the world’s fisheries are fully- to over-exploited, depleted, or in a state of collapse. Worldwide around 90% of the stocks of large predatory fish stocks are already gone. The populations of such popular fish types as tuna and mackerel have declined by 60% during the last 100 years due to overfishing.

There are two serious problems resulting from the above trends. On one hand, we are losing fish species as well as ecosystems. This leads to an imbalance in the overall ecological unity of water resources. At the same time by destroying so much fish there is a risk of losing fish as a valuable food source. In villages and towns where termination of fishing industry became a sudden reality the ecosystem collapsed, large numbers of people involved in fishing lost their sources of earnings and this led to serious economic and social problems.

Fortunately we could help reverse the destructive trend. In order to do this, there are basic rules that need to be followed by fisheries and fishermen. The basic idea is that fishing volume and consumption should be such that there is no harm to the environment. In the fishery the …
