Catch and Release.

Catch and Release is one of the methods of recreational fishing. This is usually a common practice among fly anglers. This method is based on the principle that no harm should be imparted to any animal unnecessarily. In Catch and Release fishing, the anglers resort to fishing for pleasure or sport. But they do not want to harm the fish. So the catch is released immediately into the water so that the fish can survive without any injuries. This also helps to preserve the aquatic wealth. In most countries, there is a size limit implemented by law which requires any angler to release certain species of fish below a particular size. This will help to preserve those species of fish which faces a threat of extinction.
