Grant number: 00/04300-9
Support type:BIOTA-FAPESP Program - Regular Research Grants
Duration: October 01, 2000 - September 30, 2003
Field of knowledge:Biological Sciences - Zoology - Taxonomy of Recent Groups
Principal researcher:Osvaldo Takeshi Oyakawa
Grantee:Osvaldo Takeshi Oyakawa
Home Institution: Museu de Zoologia (MZ). Universidade de São Paulo (USP). São Paulo , SP, Brazil


The principal objective of this project consists of broadening the knowledge on the ichthyofaunal composition of the basin of the Rio Ribeira de Iguarape, through studies of the taxonomy and geographical distribution based on collections in all the Conservation Units established in the region, and in other areas of the basin barely explored or totally unexplored. The principal most immediate products of the project will be: a) ichthyological survey of one of the least known areas of the State of São Paulo; b) production of publications such as: descriptions of new taxons, revision monographs, etc.; c) production of a manual and identification guides in fields aimed principally at those interested in the preservation of the environment and at the public in general; d) increase in the geographical cover of fish in the Zoology Museum; e) in the medium and long term it is hoped that the results obtained will bolster conservation policies, based on the drawing up of priority areas, sustainable management and rational exploitation of the species of commercial interest.
