​​​​​​Ichthyofauna Genetic Investigation         

Program run by the Teles Pires Hydroelectric Power Plant, in partnership with the Fundação de Amparo ao Ensino e Pesquisa  (FAEP) of the Universidade de Mogi das Cruzes - Laboratory of Genetics of Aquatic Organisms and Aquaculture (LAGOAA), aims to perform genetic analyzes of samples from 5 species of migratory fish.

The program aims to understand the population structures of species and to identify patterns in the distribution of genetic variability over geographical distances. The study will help to determine the need for future mitigation measures targeting Ichthyofauna.Pseudoplatystoma punctifer​

The following target species are part of the program: Matrinchã (Brycon falcatus), Jaú (Zungaro zungaro), Cachara (Pseudoplatystoma punctifer), Curimba (Prochilodus nigricans) and Piraíba (Brachyplatystoma filamentosum). All samples have already been collected and analyzes are in progress. Prochilodus nigricansZungaro zungaro​



 Accordion | ​​​​​​Program for Rescue and Scientific Use of Fauna

Aiming at minimizing the impacts of the project implementation, Baixo Iguaçu Hydro Power Plant has mobilized a team comprising biologists and vets to carry out activities of chasing away and rescue the wild fauna in target areas of vegetation removal, an activity associated with the project's environmental licensing.

Field teams are instructed to, whenever possible, avoid direct contact with the animals, reducing the handling impacts. When required, the team (duly authorized by the environmental body to do so), captures the animals and, if necessary, performs the emergency care to those that may be injured during the activities.

​Animals are treated and rehabilitated for later release in areas with no vegetation removal, i.e., outside the flooding area. In case of death of individuals, procedures are carried out for conservation, fixation and allocation to scientific collections, thus contributing to research development by Partner Institutions.

Baixo Iguaçu HPP team, in the development of their environmental programs, is using technology to promote conservation of the region's endemic species, in this case, a fish know as Surubim-do-Iguaçu (Steindachneridion melanodermatum), by capturing fishes, marking with combined telemetry transmissors and monitoring the moving habits of the species, installing fixed and mobile monitoring bases along the hydro basin.

So far, biologists have marked 50 individuals, and have already started to receive relevant information related to the migration behavior of the species in the study area.

The Program will provide relevant information that may be used to guide specifig conservation projects of Surubim-do-Iguaçu, which is currently classified as “In Danger" in the Environment Ministry's List of Threatened Species.​
