Catch and Release Fishing Method Hampers Feeding in Fish
  • Fish confront Feeding Problems due to Vicious Catch and Release Policy of Anglers while Fishing

While many fishermen who are amateurs and just pursuing fishing as a hobby take part in catch and release practices, such actions may cause eating issues in the fish later on.

A study showed that the flesh along the jaws of the fish was seriously injured due to the actions of anglers who were just dabbling in the art. They didn’t need these fish for food but were just fishing for fun.

Yet this human activity was immensely damaging to the fish which suffered in a cruel manner for a lifetime after they were caught and thrown back in the waters as happened in the catch and release policy.

These fish were hardly left whole after the harmful actions of amateur anglers. They were, in fact, unable to perform as viable predators. Although previously this practice was thought to be a less cruel methodology than killing the fish outright, it appears to be the case that it is even more demeaning and leads to the poor fish being damaged permanently.

Bass, trout, and salmon all eat their prey in a particular manner and fishing them by catch and release methods leave them bereft of proper feeding opportunities. This sadism has to stop.

The fish normally suck in their prey. When a hook enters their mouths, this automatically ruptures this fine feeding mechanism built by Nature in these harmless creatures. It is in a similar manner as sipping juice through a straw. When you puncture the straw, it will probably not work very well as any science project student will readily tell you.

Researchers did some experiments with perch and had half of them caught by fishing rods while the other half were caught by nets. They were then transported to the lab to see how they fed after half of them had undergone the catch and release methodology.

Although the hook and line damaged fish were still likely to try and feed on their prey, they were pretty demotivated and gave up after a few attempts. Also, they showed a slowing down and creeping lethargy in their actions. The phenomenon even showed itself when barbless hooks were employed by the marine scientists.

These fish find feeding a chore while their hook-damaged mouths are undergoing healing. More research still needs to be done but it appears to be the case that catch and release policies are extremely harmful and not benign as was previously assumed by many fishing for mere enjoyment instead of for food.

The University of California, Riverside-led research team published the findings of this new study on catch-and-release fishing, in The Journal of Experimental Biology.
