An interesting side note. Sometimes HSB caught in warm water will "lock up" after playing and landing them. The fish will have a slight bend near the tail but not show a lot of movement of any kind. This is presumably due to a lactic acid buildup that accumulates much more rapidly during physical exertion with the higher body temperature. You may be able to revive the fish by placing it under water, forcing it's mouth open and thrashing it rapidly side to side. This will force oxygen exchange on the gill surface and MAY give the fish a chance at survival. When the fish is in this kind of cramp it cannot open it's gill flaps on it's own. Bill is right...summer's tough on 'em.
Sorry, I don't know much about tilapia. That's a fish, right? Just kidding.
