Jitlands, The pros do target bull sharks, so much so that one pro told me one day that the sharks he catches here in the Mary river at Maryborough made up 50 % of his annual income. Bull shark trunks always brings a far better price per kg than mullet. And every retail outlet wkere you see Flake being sold are skark fillets from somewhere, so as rec fisermen are not alowed to sell to wholesale or retail markets the Flake in the shops must come from pros catch. The sharks caught here are netted, and I think the rules say the trunk must not be over 20 kg because any bigger you get a higher level of mercury. Bob.
