Over Fishing and Other Threats to the Declining Fish Population

INTRODUCTION It has been told that there are an unlimited number of fish in the ocean but it is almost impossible to eat too much fish because the ocean is too big. The current world population is about 6 billion people, the demand for fish was not so high. According to the video, "90% of the big fish are pulled out of the sea and the remaining 10% of the fishermen compete." fish

However, as the population of the world reaches approximately 7 billion by 2050, and more than 3 billion people are increasing since 2000, as fishing resources declined, the demand for fish and fishery capacity also declined I will. The poor coastal community is suffering from the most serious consequences of excessive development of fish resources and abuse and deterioration of the marine environment. Now science clearly communicates to us that climate change poses a major threat to the basic components of marine organisms.

In addition, fish species in the world have declined rapidly historically, but most fish species have decreased by 90%. Reduction in the number of fish species leads to changes in marine ecosystems and compromises the total productivity of marine organisms. People all over the world are suffering due to reduced productivity and impact on the marine ecosystem. The consequences of overfishing can be divided into two main problems, including environmental and economic consequences. In terms of the environmental impact of overfishing, overfishing can result in reduced fish catch of the target fish, non-target fish, short-term protected protected overfishing and ultimate ecological changes. In addition, the maximum number of fish may be removed when continuing overfishing. Overfished populations are characterized by low productivity of fish and as a result fish species are decreasing.
