Trout fishing in the rivers and lakes of the highland (sierra) of Ecuador is a rather popular sport though prohibited in national parks and national reserves. Well-known fishing spots are Laguna La Mica, Laguna San Marcos, Laguna Mojanda, Micacocha (Laguna La Mica), rio Chalupas, rio Chambo, Cosanga and Papallacta, the lacs and rivers in the Cajas National Park and in the Osogoche area.

Piranha (Piraña) fishing in the Lagunas of the ecuadorian Oriente (Amazon Rainforest) is an attraction offered with many of the jungle and rainforest adventure tours. After a refreshing bath in the laguna, equipped with just line, hook and bait, one may hook the world's most ferocious and bloody fish...

Salinas (Guayas Province) and Manta (Manabi province) on the pacific coast are the main centers for deep-sea fishing. The cool and nourishing waters of the Humboldt current providing a constant supply of baitfish are the outstanding ground for hooking dolphinfish (coryphaena hippurus), barracuda (sphyraena indiastes), blue and black marlin, yellow-finned and long-finnned tuna (thunnus albacares, thunnus alalunga) and a lot of other species.
