Apart from pollution to their water bodies or rivers, perch do not appear to be a widely threatened species.
In parts of its range, perch are a commercial fish, caught with seine and stake-nets. In the UK, it is mainly a sport fish, much prized for its fighting qualities when hooked. Perch may be caught throughout the coarse angling season (16 June – 14 March). In some of the countries where it has been introduced it is considered a pest species.
