Where can't you catch talapia at Somerset would be a harder question to answer.
But when I think real hard .........I don't recall ever catching them very far from the edge or in deep water (30ft+) at Somerset, or any other lake. Garden worms would be my 1st pick for bait, then peeled prawns. Live shrimp would also work but it would seem like such a waste.
If you want to try Nth Pine I'll give you a spot where you can't miss out on talapia.
