A woman was hospitalised in remote Queensland on Monday after being impaled by a catfish - an apparently common situation.

James Cook University Associate Professor Jamie Seymour says there was probably thousands of cases of catfish stings every year with the sting being venomous but not deadly and a catfish’s reaction to feeling threatened.

The woman who was stung was in her 30s, and was fishing from a bridge in Normanton in remote north west Queensland when the catfish fin stabbed her in the thigh. She was taken to Normanton Hospital in a stable condition and later discharged.
