Besides antiquities, Lake Nasser is renowned for its fishing – for Nile perch (the largest caught weighed 176kg, just short of the world record), huge tilapia, piranha-like tigerfish and eighteen kinds of giant catfish. After tilapia (at the bottom of the food chain) spawns in mid-March, perch and catfish thrive in depths of up to 6m till late September, after which big fish are caught in deeper water until February by trolling over submerged promontories or islands, and by shore- or fly-fishing from March to July. The best fishing grounds are in the north of the lake – beyond Amada the fish get eaten by crocodiles. Anglers base themselves on mother ships and fish in twos or threes off smaller boats. Fishing packages include meals, soft drinks and transfers from Aswan in the price; specialist rods can be hired if needed.
