CTG Brasil – Guardian of "kingdom of animals and plants"

Fish breeding and release

China Three Gorges Brasil Energia Ltda. (CTG Brasil) poured 22.86 million Brazilian reals in environmental protection in 2020, up 34% from a year earlier. The environmental protection initiative included planting 156 hectares of trees and monitoring 8,500-kilometer-long areas surrounding its reservoir. Since 2016, CTG Brasil has released a total of 16.5 million fish fry.

Dr. Norberto Castro Vianna is a biologist at the Fish Breeding Center of CTG Brasil's Salto Grande HPP, whose research focuses on  aquatic organisms, breeding and release of local fish, water quality monitoring and improvement, and aquatic plant monitoring.

Wild animal protection

In early 2020, CTG Brasil took over the management of Ilha Wildlife Conservation Center, which now has 302 animals of 53 species, including cougars, macaws, toucans, gray brockets, and anteaters. Cougar, Brazil's second largest cat, has been selected as the icon of Ilha Wildlife Conservation Center.

Cougar: The second largest cat after the jaguar, and the fourth largest cat in the world

Macaw: Native to tropical America, macaw is the most beautiful and colorful parrot and also the largest of all parrots.

Toucan: With a large beak and light weight, Toucan looks slightly like a hornbill with a mainly black and brightly colored plumage.

Gray brocket: A small and medium-sized deer whose fur color varies from region to region, ranging from brown to reddish brown.

Anteater: Found throughout Americas, it is called anteater because it likes to eat white ants.

Cracking the "gene code" to prevent invasion of exotic species

Golden mussel, also known as limnoperna fortunei, is a kind of Asian freshwater bivalve mollusc with extremely strong reproduction capacity and therefore poses immense hazard. Since entering South America with voyage ships in the early 1990s, golden mussels had been reproducing and expanding their habitats at an alarming rate. In order to reduce the negative impact of the invasive species on the economy and environment in Latin America, CTG Brasil and Brasil's Bio Bureau joins hands to use the“gene-drive” technology, which causes changes in sexual characteristics, to develop sterile offsprings of gold mussels. Then, those golden mussels reproduce sterile larvae, resulting in a decrease in their population. The company provides advanced and economical biotech solutions for controlling the invasion of golden mussels, ensuring the biodiversity of Brazil and Latin America.

Water quality monitoring

CTG Brasil monitors and reuses aquatic plants. It works with Lactec, a local scientific research institution, to develop a aquatic plant health system, and establish an information bank for aquatic plants. These efforts inform decision-making related to aquatic environment governance. Since July 2019, the company has been collaborating with SENAI, one of the most important institutions in Brazil providing formal training for specialized workers for the industry, on R&D efforts. Using pyrolysis technology, their project converts overgrowned aquatic plants in rivers and reservoirs into biofuels, promoting local ecological balance.
