Freshwater prawn farming in Brazil
At present, Macrobrachium rosenbergii is the only shrimp species commercially farmed in Brazil. Most freshwater prawn farms are small, and prawn culture is often a secondary farming activity.

Oyster output affected by environmental features of farm site
In southern Brazil, management data for Pacific cupped oyster culture were assessed to characterize production in relation to environmental parameters.

Load models support sustainable aquaculture planning for Brazil’s reservoirs
Cage aquaculture in hydroelectric reservoirs has great potential for expansion in Brazil, but there are concerns of negative environmental impacts. Careful climate zoning can assist proper siting.

Brazil’s intensive shrimp nursery systems improve PL management, grow-out ponds
Intensive nursery systems are an extension of hatcheries to acclimate postlarvae to farm conditions and assess quality and health prior to pond stocking.

Tilapia cage farm management in Brazil
Much of Brazil’s expanding tilapia aquaculture takes place in floating cages with sturdy frames and nets made from plastic-coated steel or polypropylene.

Brazilian researchers examine amino acids in Nile tilapia diets
Determining dietary requirements for tilapia requires precise formulation. Individual amino acids must be considered to establish well-balanced diets.

Shrimp farming in Brazil
Shrimp farming in Brazil grew rapidly from the late 1990s to 2003. Brazil can again become a global leader, for it has 600,000 ha of suitable area with excellent natural conditions and infrastructure, and a large internal market.

Disease risk factors for shrimp production in Brazil
For two years of data, the effects of management, season, stocking density and salinity on the incidence of disease in northeastern Brazil’s shrimp farms were found to be highly significant.
