Questions arise with the U.N. Food and Agricultural Organization’s (FAO) projections regarding the wild fish harvest in 2012. Specifically about the ecological damages that have been inflicted on wild fish populations. FAO’s projections estimate that the wild fish harvest will fall 2 percent from 2011, which means that this haul will be now 4% below the all-time greatest haul of wild fish which was reached in 1996. With rapid growth throughout the 1980s and 90s due to the expansion of fishing into new fishing stocks the total wild fish harvest climbed, then held steady until in recent years the total wild fish haul began to fall.
Based on an evaluation in 2009 the FAO reported that 57% of the oceanic fish stocks are now “fully exploited” meaning that if the fishing efforts regarding these stocks were to increase the stock would begin to slowly decrease and they would tumble into the category of “overexploited”. 30% of the oceans fish stocks have already been declared over exploited and immediate action must be taken to stop the destruction of our oceans. Based on the last 38 years, starting from a study in 1974, and continuing to today it seems that the hope for the survival of our oceans aren’t all that bright. In 1974 it was reported that 40% of the oceans wild fish stocks were under exploited, today only approximately 13% of the oceans fish stocks can be classified as “underexploited”. With a greater percentage of our oceans overexploited (30%) than they are underexploited (13%) it would seems that not only the industry but the oceans will soon fail if corrective actions aren’t taken.
However, thankfully scientists and organizations have dedicated themselves to working on these issues and actions are being taken to improve the remaining fish stocks. Actions, like the reduction of fishing pressures, are being enforced in attempts to improve the spawning success of future fish. Scientists are targeting “forage fish” as species to reduce fishing pressures on as forage fish are the fish that support the stability of the species higher up on the food chain, like salmon and tuna which are both popularly consumed fish.
Other actions, like restrictions on gear types, total catch sizes and dividing shares of catches among fishers and the designation of marine protected areas and “no-take” zones are also proving to improve the success of fishing stocks. For instance in Australia a study performed in 2010 revealed that no-take reserves had in six years doubled the populations of fish in no-take zones as well improving the total size of the fish meaning a greater biomass per fish. Not only did the areas of no-take increase the areas around these reserves increased their fish populations. Due to the success of theses efforts Australia announced this past June that it is going to increase its total number of reserves resulting in a total of one third of its waters being marked as protected.
