English to Hungarian Other Fisheries fishing methods

Catch and release is a practice within recreational fishing intended as a technique of conservation. After capture, the fish are unhooked and returned to the water. Often, a fast measurement and weighing of the fish is worthwhile. Using barbless hooks, it is often possible to release the fish without removing it from the water (a slack line is frequently sufficient).
