Sustainable Aquaculture
This document discusses sustainable aquaculture and reducing the environmental impacts of intensive aquaculture. It notes that while aquaculture produces only 2% of the world's food from 70% of the planet that is water, a few species dominate global aquaculture. Intensive aquaculture can pollute if it discharges waste effluents and emissions into the environment. The document explores more sustainable aquaculture systems like recirculating aquaculture systems, integrated multi-trophic aquaculture, and biomitcry-inspired designs to mimic natural ecosystems. The goal is to produce more aquaculture in an environmentally-friendly way.
