Facility for the aquaculture of animal species

A facility for the aquaculture of a first animal species that consumes protein and produces waste containing urea and nitrogenous sludge, comprising:

• a hatchery comprising at least one clean-water laying tank, at least one clean-water hatching tank, and at least one clean-water larva tank;
• at least one clean-water pre-maturation tank and at least one maturation tank, with means for supplying protein-rich feed;
• and
• at least one first rearing tank for the first animal species containing water and biofloc containing bacteria that carry out nitrification of the waste;
• at least one other rearing tank for a second animal species, the second animal species acting as a biofilter for nitrogenous products;
• means for transferring the nitrogenous sludge that has accumulated in the first rearing tanks to the at least one other rearing tank;
• and
• means for transforming the species of the second animal species into feed protein, and for transferring the feed protein to the at least one pre-maturation tank and the at least one maturation tank.
