Recreational fishing, as opposed to other types of fishing, is not a commercial activity, but it is have a good time in the company of friends or family. Call ictioturismo, or better known as “catch and release” is customary in many places where recreational fishing is practiced. This technique of recreational fisheries, the goal is to release fish alive once they were caught, this is due to an attitude of ethical and responsible; what many do not know when practicing this sport fishing, however, is that once the fish are released, 40 percent of them die after the capture. Recreational fishing with bait is the most deadly activity because the fish caught are smitten with tears or bleeds internally.
Although the purpose of recreational fishing that uses philosophy “catch and release” intends to have fun without killing the fish, in reality this is not achieved, because anyway the fish dies. There are many reasons why this happens, but a major stress as a result of physical exertion produces in the fish a deficit of oxygen in the tissues, which forces the muscles to function without oxygen causing lactic acid accumulated in muscle tissue, and then into the blood.
All this causes changes in blood pH, alterations in metabolic processes and finally death. At times, thanks to the recreational fishing where it is customary to release the captured fish, seems that the animal is still alive when it is released, but the reality is that the chemical imbalance in your blood can kill him until three days after having been captured.
As we had said of recreational fishing, the use of hooks is one of the causes of mortality, since these produce wounds ranging from very mild to fatal. When a fish is caught in a recreational fishing, here at ToolkitforFishing that use bait are engaged by the gills or stomach when the fish are caught.
The mortality of the fish released in a recreational fishing
One of the most important factors affecting the fish in a recreational fishing are exposure to the air, the temperature rise of the water once they come out to the surface and an excess of manipulation of the hook. In addition, fish suffer from physiological stress, this means that there is an increase in corticosteroid hormones, which inhibit reproductive processes, so the conservation of the populations also is threatened.
Does not have much case return a captured fish, since the only fact to raise it to the surface represents a change in pressure that can cause that they will inflate their tumble vesicles, which control their buoyancy. Nor is taken into account in a recreational fisheries management and fish body contact with dry surfaces, like for example networks, have the ability to remove the layers of mucous from your body, causing are more prone to bacteria and other pathogens that infect your skin.
In addition, we must take into account that recreational fishing in these animals feel pain. For that reason, it is sometimes more pious a death fast, that return them to the water with risk that will die in a few days, or worse still, to pollute its waters and endanger his community.
Recommendations to return to fish in a recreational fishing
Although with different levels of perception compared to us, the fish can also feel pain at the time of being caught, why struggle to escape, but many times by compassion decide fishermen take a picture and then release the fish, to not affect you or take away life, when in reality is quite the opposite.
