While most marine aquaculture in Vietnam has been based on traditional small-scale cage operations in protected locations, the development of larger offshore cage systems could lead to industry expansion.
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.
Farm cages should be sited where water quality is good and water velocity is adequate. The size, shape and position of cages should be selected to favor rapid flushing.
