to compose a picture of the overfishing crisis. The recent developments of Atlantic cod and squid are discussed in more detail to provide a pattern that may lead to empty oceans in the future. Accounting for fish in the ocean. There are many methods to account for the number of fish in the ocean. However, there are many uncertainties within any models of assessment. The reliability of instruments and the weather condition during survey have great influence over the results (Smith and Gavaris

Abstract: Overfishing is the process of fishing to the point where more fish are caught than the population can replace through natural reproduction. It may seem profitable to quickly grab as much fish as you can, but it is extremely harmful to the marine ecosystem. The results of this have lasting impacts on the balance of life in the oceans, and the social and economic well-being of the coastal communities who depend on fish for their way of life. Fortunately, there are efforts being done to help

The aquaculture industry has been plagued issues such as water pollution, fish disease outbreaks, destruction of coastal habitat and escapes that have tarnished its reputation and stimulated significant backlash against the industry. In response, the industry turned to placing marine farming systems miles offshore, in deeper waters with large currents to reduce the environmental risks associated with conventional aquaculture. Studies have shown when cited properly with adequate flushing rates, offshore

of ecosystems and resulting in great amount of reduction of stocks in fish and marine mammals from the 11th century onwards (Roberts, 2009). Ocean overfishing is defined as catching fish from sea at rates too high thus lead to depletion of the stock of fish. As today, there are almost 90 percent of fish population have been depleted by humans worldwide because fish is considered as a sources of food. In 2010, 148 million tonnes of fish from fisheries and aquaculture were used by the world and 86

the continents, South African waters has become a viable target for international role players to maintain the demand of fishing operations and fish stocks that is required for global markets. Due to inadequately monitored fishing operations, overfishing has left South Africa with a significant shortage of food resources for the poor, who depend on fish as their staple diet. According to the World Wildlife Fund, “Seafood is the largest traded food commodity in the world. Approximately three billion

No overfishing or no fishing. Overfishing is an enormous issue that needs to be corrected or there will be no more fish to catch in the future. The true definition of overfishing is as defined by the national fisheries act from 1996 overfishing is “a rate or level of fishing mortality that jeopardizes a fishery's capacity to produce maximum sustainable yield (MSY) on a continuing basis(kennedy, 2016)." Some of the facts of overfishing are so shocking they would blow you out of the water, as well

different species of fish and over 2 million other animal and plant species found in our oceans. Overfishing can be defined in a number of ways. However, everything comes down to one simple point: Catching too much fish for the system to support leads to an overall degradation to the system. Overfishing is a non-sustainable use of the oceans. The earliest overfishing occurred in the early 1800s when humans, seeking blubber for lamp oil, decimated the whale population. Some fish that we eat, including

When looking at the state of the fish stocks of which information is available, confirmed that the proportion of overexploited, depleted and recovering stocks have remained relatively stable over the last 10-15 years, after the observed upward trend of operating in the 1970s and 1980s. It is estimated that in 2007 52% of the fish are fully exploited, meaning that the catches are close to their maximum permissible limit for sustainable

1997). The total revenues for marine fisheries today is $91.2 billion This huge industry also supplies a large food source to populations around the world and is an important source of jobs for many countries. However, almost half of the world’s fish stocks are fully exploited or overexploited. Fisheries management has failed to reach the one goal of marine fisheries, sustainability.

management practices. Incredibly, 2010 saw a profound rebound with an estimated 34 million returns, indicating resilience of this species but also giving rise to many unanswered questions in explanation (Cohen, 2010). Even though fish harvesting had declined, fish stocks were still plummeting; people wanted answers, and in 2009, a Canadian federal judicial inquiry was launched to investigate fisheries management practices, as carried out by Fisheries and Oceans Canada (DFO) by means of the Cohen Commission
