MULTITROPHIC SYSTEM FOR AQUACULTURE PRODUCTION IN FLOATING AND SUBMERSIBLE CAGES

Abstract

The multitrophic system for aquaculture production in floating and submersible cages is a highly efficient, innovative biotechnology for the cultivation of different hydrobionts. The integrated production operates in a closed cycle with the aim to increase the economic efficiency of the aquafarm. The effective use of waste organic and dissolved inorganic substances from the feeding of fish, cultivated in rigid wall and net cages - floating and submerged, is accomplished. Cultivated mussels near the cages use waste organic matters. The algae cultivation system is installed after the shellfish cultivation system and they use the dissolved inorganic substances. This cultivation technology ensures sustainable and environmentally friendly aquaculture, while preserving the equilibrium in the aquatic ecosystem.
