CZ137-QJ- aquaculture/AQUA

Effective and sustainable use of nutrients in intenzive aquaculture using multitrophic systems.

Description

Research and development of multitrophic aquaculture systems aimed at effective and sustainable nutrient utilization, waste recycling, reduction of environmental impacts and improvement of economic efficiency.

Sector

A3.2Aquaculture

Needs/ Problem statement

Intensive aquaculture suffers from nutrient losses and environmental impacts, requiring sustainable systems for efficient nutrient recycling.

Objective

Develop and validate multitrophic aquaculture systems for efficient nutrient utilization, waste recycling, reduced environmental impact, and improved economic efficiency of fish and aquatic organism production.
