The Amazon home to around 10% of global aquatic biodiversity

The Amazon river and its affluents are filled with more than 3,000 species of fish, including piranhas and electric feared eels. As in the case of many other types of wildlife, it is almost certain that there are still many more species to be discovered.

The exceptional biological richness of the Amazon opens high potential for the fishing industry and sustainable development. Currently, the subsistence fishing and the commercial fishing exploit at least 150 different species and thousands of Amazon residents rely on fish for food.

Fishing activity generates more than $ 50 million of commercial value and according to experts, could produce three times in the coming years, “considering” that only half of the fish consumed in production comes from the region, while the rest comes from Argentina, Chile.

But, to imagine a fishing sustainable development leads to a condition: to preserve aquatic resources of the disturbances they face.


Mercury pollution, destruction of ecosystems deforestation introduction of nonnative species and hydroelectric dams are the threats to the Amazon and its biodiversity.

With its mighty rivers the Amazon region has great potential for the construction of dams. Hydropower projects are carried out in the Amazon countries like Brazil are undoubtedly one of the biggest challenges for the conservation of aquatic resources. Dams disturb the hydrological regime and create a physical barrier to the movement of fish, affecting their life cycles and reproduction.

Amazonian fishes for the world

For aquarium enthusiasts, this is the source that provides as many fish species that populate today shops and aquariums in the world. It is so broad its contribution in fish species that listing them occupies much place .

Conservation studies place the number of Amazonian fish species in the range of 2,500, other experts place it at 5,000. More than twice the number of known species in the Atlantic Ocean.
