Mozambique offers some of the world's best fishing and some of the most challenging big game fishing in southern Africa, particularly around Guinjata Bay and the deep waters of the Mozambique Channel. The Bazaruto and Quirimbas Archipelagos are considered among the best fishing destinations in Mozambique, but there are many other wonderful destinations, with almost every lodge and beach resort offering a range of fishing activities and tours. Black, blue and striped marlin, sailfish, shortbill spearfish, wahoo, dorado, various tuna species, king and queen mackerel, barracuda and snappers are among the huge fish found in Mozambique's rich waters. Some weighing over 1,000 pounds (454kg) can be caught, and a number of records have been set along the coast; however, a catch and release system is encouraged to protect the natural resources, so fishermen have to make do with photographs as trophies more often than not. A number of centres along the coast offer rock fishing, surf fishing, estuary fishing, offshore fishing and fly fishing, and there is something to appeal to all levels of expertise and experience. There are also a number of tour operators offering multi-day fishing tours in Mozambique.
