Overfishing in the world's oceans has faced numerous social, environmental and economic problems in recent years. points out that the amount of marine animals has decreased by half since 1970. For the purposes of this essay, overfishing can be defined as excessive catching of fish in the ocean. Overfishing is the focus of this essay where some explanations of several substantial problems related to overfishing in the world's oceans are shared. The various reasons for major problems related to overfishing in the world's oceans include; depletion of fish stocks, socio-economic consequences and ecosystem destruction. Say no to plagiarism.

Overfishing has meant that several marine species are almost or completely at risk of extinction. An estimated 37 marine species are at risk of extinction and 14 are near threatened in southern Angola and northern Mauritania. For example, the waters of West Africa are particularly advantageous for fishing because they are one of the most reproductive areas in the world. On the western and central coast of Africa there are numerous endangered species such as osteichthyans, the Madeira sardine and the cassava croaker. Osteichthyes are also known as "bony fishes" and include a total of 1,288 fishes that are generally found on the west coast of Africa. Furthermore, over the last decade, there has been a 30%-60% reduction in black cassava due to overfishing. This result indicates that unsustainable fishing has caused a substantial reduction in the number of fish in recent years and, therefore, has endangered some species. Furthermore, it is said that 30% of the fish are sold out. To further illustrate this concept, data collected from over 70% of fish are already exploited or depleted. Additionally, due to technological advancement, commercial fishermen have used "purse seine" as a method of catching large numbers of bluefin tuna along with one vessel. Since the net catches a large amount of fish at one time, many other species are included. Because of this, unwanted species are killed and then ignored in the ocean. stresses that purse seine fishing has a major impact on the reproduction process of tuna and causes its depletion. Therefore, continued illegal and unregulated fishing methods further significantly impact the excessive depletion of fish stocks in the future. Secondly, socioeconomic effect is another reason why overfishing has become a major problem around the world. Socio-economic impact refers to daily consumption for survival and the source of income earned through fishing. However, as overfishing gradually continues, there will be no more fish available for daily consumption and income. According to the, fish is an important part of a regular diet, especially in Southeast Asia and Africa, as it contains 50% of the protein needed by an adult. Research highlights that fish helps provide energy, protein and prevent nutritional deficiencies. As a result, fish consumption is a vital part of a healthy and consistent daily diet. Furthermore, overfishing will lead to less fish consumption, which could potentially cause malnutrition, particularly among children. For example, fish consumption was 9.0 kg per capita in 1961 and rose to 20.2 kg in 2015. The amount of consumption of.
