Tilapia Production Using Biofloc Technology: Saving Water, Waste Recycling Improves Economics

摘要

Biofloc systems enable more intensive tilapia production. The fish adapt to the conditions within biofloc svstems and grow well by utilizing the bioflocs as a feed source. The recycling of feed and minimization of water exchange are important contributions to the economy of tilapia production. Understanding the biofloc system, monitoring and fast response to negative developments arc essential for successful culture. Production of tilapia has risen tremendously in the last few decades. At about 3 mmtin 2010, the volume of worldwide tilapia production was second only to carps among fish. Current trends indicate a continuous growth of production and expanded penetration of tilapia in a variety of markets, from expensive restaurants to local households all around the world. Although higher production levels are needed, increased aquaculture production is limited globally by the availability of suitable water and land. The most feasible and environmentally acceptable way to raise aquaculture production is by the use of intensive production systems.
