Sample Research Paper on Overfishing

Overfishing refers to the act of taking out too many fish from the water bodies (Palkovacs, 2011) . Although fishing is legal, there are certain restrictions about the amount of fishing that should be done. This helps to ensure that the ones remaining get to reproduce. When overfishing occurs, there is a disturbance in the balance of ocean life. It also causes distress to the people who reside along the water bodies and depend on fishing for their livelihood. Fishing has always been a source of livelihood for millions of people around the world. This however is being threatened by overfishing and other unsustainable fishing practices are straining the fish population. Most of the fisheries in the world have been strained to a situation that is so dire that most fish species have been threatened. Part of the problem is the increase in technologies that have been invented that assist in fishing. The technologies not only help in being able to find more fish within a short time, but also in reaching the farthest and deepest parts of the water bodies where these fishes are found.

One of the technologies that exist is known as seine fishing. A seine is fishing net which is hung in the water vertically (Marçalo, 2006). Weights are used to hold its bottom to the ground. Seiners are boats that are used for navigation to the water bodies in order for the seines to be launched. Although there are different types of seines, the most common one is referred to as purse seine. The use of seine is so rampant that there are restrictions in certain countries about its use. In a year, seine fishing is responsible for the capture of 62 percent of the fish that are caught. Users who would like to go deep sea fishing with purse seines usually have to seek permission from the authorities. This kind of fishing is restricted because of its all inclusive nature that sometimes leads to the capture of negative species thus threatening their existence even more.

The catch limitation system is one of the government policies that are meant to control fishing. The main aspect of this system is the number of fishes that can be caught in a specified period of time. This is meant to ensure that the rare species of fish are protected and also that the ones that are common are given the chance to reproduce and multiply so that the activity of fishing can continue for a long time.

Deciding the total allowable catch is another policy for fishing. Each year, the government scientifically takes stock of the fishes and determines the total number that are safe for fishing without ruining the balance of the fish in water. Although this policy is supposed to assist the government in establishment of fishing maximum, this policy has not mange d to effectively serve its purpose. The reason of this is that scientists who are looked up to for provision of this information have failed in one way or another (Palkovacs, 2011). They have failed to give an accurate number of the population of fish thus leading to a wrong maximum number being given. Mostly, they have overestimated this number therefore leading to the government giving a larger number of fish that can be caught than is appropriate. This therefore continues to be a threat to fish stocks.
