Measuring fish

Measuring finfish

Fin fish are measured from the tip of their snout to the end of their tail (see illustration). If you unintentionally take a fish (including fin fish or crustaceans) that is not the legal size or is unwanted, return it to the water immediately, taking as much care as possible to avoid causing injury to the fish.
