Recreational fishing makes fish hurt badly

Catching and releasing fish seems to bring dual benefits, while helping those who enjoy recreational fishing and helping their prey to swim safely. Actually, it is not. A recent study shows that fish, including sharks, can suffer from traumatic trauma after this incident that they can die shortly afterwards.

The main finding refers to hooks and fishing lines, because catching with nets rarely leads to their deaths. Sascha Danylchuk, head of research at the Cape Eleuthera Institute in the Bahamas, said that even if survived after being released, they are more likely to be infertile or susceptible to disease.

Danylchuk and his colleagues studied sardines, a tropical fish whose speed and caution make them attractive targets for recreational fishermen.

The team had to catch and release 88 sardines by traditional fishing. The second group of fish is caught by the net. After release, each fish is followed for 1 hour later. As a result, those who lose their balance, or lose their ability to swim normally, are 6 times more likely to die.

"When the imbalance happens, we as fishermen see the fish rolling to the side and finally to the nose down instead of swimming like healthy ones," Danylchuk said.

Like the person running a marathon, when the fish is caught, the fish is like " knocking into a wall " and becoming unsteady and disoriented. The wound on the hook and the thrust of being caught also contributes to the loss of balance.

According to the researchers, simple techniques that can help reduce these unnecessary deaths, for example, instead of removing fish hooks that are swallowed by fish, cutting wires can increase their survival from 12 up 85%, or use non-pronged hooks, the nets catch no hook.
