Catfish use their venomous spines for defense only. When a catfish gets agitated, it extends its spines, locks them in place and waits. A frightened catfish strikes when a predator, including a human hand, comes within range. Catfish Sting Treatment Stings usually occur when the fish is handled. Symptoms include a throbbing or scalding pain lasting 30-60 minutes. Immersing the affected area in water as hot as is tolerable usually relieves pain from a sting. Spines should be removed with tweezers. The wound should be scrubbed and irrigated with fresh water. The wound should not be taped or sewn together.
