Why Are Norwegian Aquaculture Semi-Submersible?
Last time we explained why one of the distinguishing features of aquaculture in Norway is the preference for round shapes, today we will analyze the key reasons why semi-submersible cages were chosen.
1. Semi-Submersible Design for Environmental Benefits
The semi-submersible design of certain Norwegian cages takes advantage of the unique hydrodynamics of the marine environment. By being partially submerged, these cages experience less surface agitation, reducing the effects of wind and waves. This design not only enhances the stability of the cages but also minimizes the exposure of the fish to extreme weather conditions and predators. Furthermore, the semi-submersible structure leads to reduced water turbulence, which can help maintain better water quality and fish health.
2. Reduced Environmental Impact
Round and semi-submersible cages can also contribute to a reduced environmental impact. Their design allows for more efficient waste dispersal and decreased feed loss, which minimizes the ecological footprint of aquaculture operations. By efficiently managing waste and minimizing feed wastage, these designs help protect local marine ecosystems and promote sustainable practices in aquaculture.
Conclusion:
The preference for round and semi-submersible cages in Norway’s aquaculture industry is driven by a combination of factors that enhance water circulation, stability, fish welfare, and adaptability to technology. These cage designs not only promote efficient aquaculture practices but also align with the industry's growing focus on sustainability and environmental stewardship. As the global demand for responsibly farmed seafood continues to rise, the innovative cage designs utilized in Norwegian aquaculture will likely serve as a model for best practices in the industry.
