Environmental considerations

Aquaculture has faced criticism for its potential negative environmental impact. Improper waste management, water pollution, and the spread of diseases and parasites from farmed fish to wild populations have been concerns associated with some aquaculture practices [2]. However, the industry has made significant strides in adopting sustainable practices to minimize these impacts. One such approach is integrated Multi-Trophic Aquaculture (IMTA), which involves cultivating multiple species in close proximity to create a symbiotic relationship. By combining fish, shellfish, and algae, IMTA maximizes resource utilization, reduces waste, and enhances water quality. This practice reduces the need for external feed inputs, lowers the environmental footprint, and promotes ecosystem health [3]. Additionally, Recirculating Aquaculture Systems (RAS) have gained popularity. RAS recirculates and treats water within a closed-loop system, minimizing water usage and reducing the risk of pollution. These systems control factors such as temperature, oxygen levels, and waste management, providing optimal conditions for fish growth while minimizing environmental impact.
