The ichthyofauna of the region comprises 71 species of fish, some of them of great commercial value.
Many fish species use the mangroves as oviposition areas, as well as breeding grounds, contributing to the high diversity of ichthyofauna in this region.
Considering that many other species of vertebrates also depend on fish for food, this close relationship between the ichthyofauna and the mangroves is crucial to the maintenance of diversity in these communities.
A prominent feature, in terms of biodiversity, is Lake Chapala, which supports a rich and endemic ichthyofauna that is currently in danger of extinction.
This has changed the dominant species of ichthyofauna.
Mamirauá: Because of flooding, much of the wildlife, except for the ichthyofauna, is higher in endemism than diversity, especially in the campinaranas.
The ichthyofauna includes nearly 85% of the reef fish species endemic to the west Indian Ocean region (399 species) including several commercially important endemics such as the slinger Charysoblephous puniceus. 991 species have been recorded. including summer aggregations of ragged-toothed shark Tiburon odontaspis and whale shark Rhynchodon typus.
The development of aquiculture (780 ha) creates reproductive and nutritive stresses to the detriment of local freshwater ichthyofauna.
"One of the most significant results is that the ichthyofauna of the Bellingshausen Sea, contrary to what was previously believed, is more closely related to that of the Eastern Antarctic than the Western", highlighted the researcher.
