What should be done with unused catch while fishing?

When dealing with unused catch while fishing, the most responsible action is to dispose of it properly while onshore. This approach ensures that any fish not kept are handled in a way that minimizes harm to the ecosystem. Proper disposal might include using designated fish cleaning stations or following local regulations for waste disposal that protect the aquatic environment.

This method promotes sustainable fishing practices and reduces the risk of pollution or disrupting local wildlife, which can occur if fish are simply thrown overboard or left in live wells for an extended period. Returning the fish to the water unharmed is also a good practice but only applies to catch that has not been harmed and is able to survive. Keeping fish in a live well is only appropriate when the intent is to keep them for consumption, and it doesn't address the concern of proper disposal if the catch is wasted.
