Livewell

A livewell is a water tank found on many fishing boats that is used to keep live bait and caught fish alive. It works by pumping natural water from the surrounding waterbody into the tank, as well as an air pump for water aeration. It is a standard design feature in many modern sport fishing boats and yachts, especially those used in fishing tournaments, as competitions typically weigh participants' catch only at the end of the round and thus require the caught fish to be kept in the condition they were caught until the boat returns to dock.
