![]() In North America, some successful operations are extremely limited in size, while in Europe attaining economies of scale seems to be a more important issue. Equipment options and management expertise impact both technical and economic feasibility. Many functional configurations exist but profitability depends on capital costs, operating costs, survival and growth rates, and market conditions. When considering raising shrimp in tank systems, both technical and economic factors must be addressed. In tropical regions, a building is not necessarily required, but it provides security and protection from the elements. Adequate ventilation is also crucial to reduce damage from mildew and humidity. ![]() Floors can be as simple as sand and gravel or concrete with trough drains, but in temperate areas walls and ceilings must be highly insulated. In both temperate and tropical regions, buildings can be retrofit from other uses, but electrical distribution and outlets must be upgraded for outdoor conditions and with ground-fault interrupt circuits. Lack of access to land for pond-based production is a real issue in many countries where conditions are otherwise suited to shrimp farming. Questions of resource availability, especially land and water (in this case brackish or saline water) have also sparked interest in tank-based shrimp farming in tropical regions. This strategy reduces the need for cold chain middlemen, in both developed and less-developed regions. Factors driving this trend include proximity to markets and the ability to offer fresh product to consumers.
