What is the term for the practice of catching and then releasing fish back into the water?

The term for the practice of catching and then releasing fish back into the water is "Catch and Release." This method is widely promoted as a conservation technique that helps maintain fish populations and ensure the sustainability of aquatic ecosystems. Catch and release allows anglers to enjoy the sport of fishing without permanently removing fish from their habitat, which can lead to overfishing and depletion of certain species. It encourages responsible fishing practices and helps maintain balanced ecosystems, as it allows more fish to grow to maturity and reproduce.

Other terms in the choices refer to broader concepts in fishing. Angling is a general term for fishing using a hook and line, without necessarily implying the catch and release aspect. Fly fishing is a specific technique of angling that uses artificial flies to catch fish. Sport fishing refers to fishing done for pleasure, emphasizing the recreational aspect but does not specify whether the fish are kept or released. Catch and Release is distinct as it specifically focuses on the practice of returning the fish to the water after they have been caught.
