Quite a selection from Red Snapper to Turbot...BUT....unless you REALLY like Turbot and want to pay 516 fl ($286) for a whole fish (maybe 5-6 pounds) the snapper seems to be a good choice...
FL 516.79 is the price on the package. Saw another fish a couple of days prior with right around the same price
Edit: On another Carrefour note: at checkout some crew were provisioning a ship and the cashier was still scanning items (two baskets to go) and the price was up to FL 3196 and counting. Good business for that market
