Sport fishing or recreational fishing comes in with a whole lot of rules along with regulations as well. It has conventions as well as licensing restrictions accompanied by various laws, which limit the ways by which fishes might be caught. The IFGA (International Game Fish Association) the governing body or the leading authority of all the angling pursuits is mainly responsible for laying out the rules and overseeing the voluntary guideline set. The most common guidelines for recreational fishing include prohibition of nets and using hooks that are not inside the mouth for catching fishes. 

Besides the governments also enforce various regulations that are much required for sustainable practices so that any of the species might not be endangered thereby maintaining the balance in the environment and nature. As for example, in the country of the Republic of Ireland, the Central Fisheries Board oversees all the implementation for the angling regulations like controlling the angling lures, permissible number of baits and hooks, restrictions based on natural conservations as well as the licensing requirements.

A fishing permit or license is extremely necessary to take part in sport fishing. Carrying on the activity without any valid fishing license is considered as a crime not only in the government jurisdiction but also against environment conservation. The licenses required for sport fishing depends on various factors like jurisdiction where the permits might be required by either the government or the property owner. Nevertheless, the activity should be enjoyed as long as there is no harm done to the environmental balance.
