"Fish off" is a colloquial term used in some contexts to refer to the act of fishing without permission or in a way that disrespects the rights of others. It can refer to fishing in someone else's fishing ground, or fishing in a way that disrespects the rules or wishes of the owner of the fishery.

This term is often used in reference to environmental issues, such as when someone fishes in a way that disrupts the natural balance of a fishery or when someone fishes in a way that disrespects the rights of other fishermen. It can also be used to refer to other situations where someone infringes on someone else's rights, such as when someone trespasses on someone else's property or when someone infringes on someone else's intellectual property rights.
