Pisciculture

Duzau Fish farming or pisciculture involves raising fish commercially in tanks or enclosures such as fish ponds, usually for food.

The processing and marketing of the fish harvest have also expanded greatly. Assisted by improvements in transportation and conservation technology, and spurred by increased real commercial incomes, ever increasing volumes of catch are processed, packaged and marketed as high-value food commodities. This trend is likely to continue at an even faster rate in the future. This means a substantially increased value added per unit of catch. However, it also represents a replacement of the traditional fish-processing and distribution activity by high-technology, industrial production methods. More seriously, this process (sometimes referred to as the globalization of fish markets) threatens to strip underdeveloped communities of their staple fish supply due to overbidding from the industrial world.
