Every fisherman has a hard-luck story about the one that got away.
But today, boaties across Auckland are being asked to do just that to support Coastguard, the charity saving lives at sea.
In a novel twist on the traditional bucket donation, Coastguard is not asking boaties to donate cash - they are being asked to donate a fish.
Fishermen coming off the water around Auckland boat ramps will be able to donate what they have caught.
Coastguard will keep those fish on ice overnight, and auction them at Silo Park from midday tomorrow.
