Embrapa Tabuleiros Costeiros is conducting research on malacoculture with native species in Brazilian tropical waters, specifically cultivating oysters using different techniques and structures. The goal is to increase growth rates and survival of the native oyster, Crassostrea gasar, in estuarine waters. The institution is also exploring the use of artificial collectors for oyster seeds in collaboration with two Swedish researchers. This work is part of the international Aquavitae project, aimed at increasing production and improving the sustainability of aquaculture. The Swedish researchers visited Embrapa to understand Brazil's oyster cultivation practices and the use of artificial collectors.
