Fundamentals of bioflocs technology (BFT). An alternative for fish farming in Colombia. A review

Abstract

Conventional systems for fish production in Colombia begin to decline mainly due to the need for large quantities of increasingly scarce water, increasing pollution of the tributaries of discharge, increased cost of food with great waste of these and other factors adverse environmental and droughts in large areas of territory and different volumes of production per unit of area or volume. Therefore the searches for new potential for fish production is environmentally friendly, socially inclusive and profitable are becoming more pressing. One of the alternatives that are beginning to captivate the interest of farmers is the system of super intensive production bioflocs technology (BFT), which is based on the accumulation of waste seize food, organic and inorganic toxic compounds through of microorganisms in aquatic environments, giving dominance conditions and heterotrophic to autotrophi production.

Key words: Microorganisms; bioflocs technology; fish production; nutrients.
