Ocean fishery sustainability - Essay Example This is in relation to the fact that these factors are the main contributors of overfishing. According to National Geographic (1), the 90 million tons of fish caught from the ocean by 1989 was the main contributing factor for the current low number of fish in the ocean. From this assertion, it is apparent that the population of fish in the oceans cannot withstand fishing that is beyond 90 million tons. Though challenging, it is possible to make ocean fisheries sustainable. One of the key things that need to be done in order to achieve the sustainability of fisheries include recovering the depleted fish stocks in addition to maintaining them at levels above that is required to generate Maximum Sustainable Yield (Juzgado 1). Restoring the destroyed marine ecosystems to a condition that is healthy will protect the ocean organisms (Juzgado 1). According to Ale and Howe (1), the logistic growth curve is used by scientists to predict the carrying capacity of fish in a given water body. Despite its extensive use in the field of fisheries, it is apparent that the population of fish continues to collapse. The main reason for the failure of the logistic growth curve in management of the population of fish is that predictions often are not useful because they do not involve the prediction of the community composition (Ale and Howe 1). In addition to the options of control of overfishing discussed above, elevation of the oceans to the topmost levels of the UN system will aid reduce the problems associated with overfishing (Juzgado 1). This will be achieved by the UN system enabling not only a cross-cutting approach, but also a timely response to key threats and opportunities to the oceans’ ecosystem. Since overfishing has become a menace in the whole world, it is essential for the marine sanctuaries to be established so as to provide a secure habitat for the fish.
