Fishing techniques refer to the various methods used to catch fish. Common techniques include angling, where a hook is baited and cast into the water, and netting, which involves using a net to trap fish. Other methods include trapping, where fish are lured into a confined space, and spearfishing, where fish are caught using a spear or harpoon. Each technique can be adapted based on the type of fish being targeted and the environment. For instance, fly fishing is popular for catching species like trout in freshwater streams, while trolling is often used in saltwater to catch larger fish like tuna.
