Land-based vs. Sea-based Aquaculture Operations

September 24, 2024

As the global demand for seafood continues to rise, aquaculture is stepping up as a key solution. But not all fish farming is created equal. Two major methods –land-based and sea-based aquaculture – offer different benefits, with each playing a vital role in feeding the world sustainably.

Land-based aquaculture

Land-based aquaculture provides unparalleled control over the growing environment. Fish are raised in carefully monitored tanks or ponds, where water quality, temperature, and oxygen levels can be optimized for fish health. This controlled setting helps reduce disease outbreaks and limits environmental impact, as effluent and waste are easier to manage. Additionally, land-based systems eliminate the risk of fish escaping and mingling with wild populations, protecting local ecosystems.

While these systems require significant initial investment and higher energy use, they offer a more efficient use of space and can be located closer to markets, reducing transportation costs and carbon emissions.

Sea-based aquaculture

Sea-based aquaculture, also known as open-ocean farming, allows fish to grow in their natural environment. This method uses large, floating cages, which benefit from a constant flow of fresh ocean water, reducing the buildup of waste and ensuring good water quality. Sea-based systems are scalable, supporting high production volumes to meet global seafood demand.

While sea-based farming brings logistical challenges and environmental concerns, such as the risk of escapes and waste affecting nearby ecosystems, its lower operating costs and reliance on natural processes make it a viable option for large-scale operations.

The balance of aquaculture

Both systems have their strengths. Land-based aquaculture offers unmatched control and environmental protection, while sea-based aquaculture supports large-scale production in a more natural setting. As as technology evolves, we continue to find innovative ways to balance efficiency, environmental stewardship, and high-quality seafood production.

Amar Seafood operates both land-based and sea-based aquaculture operations. Our main focus is on developing land-based facilities across all of our locations in Canada, Scotland and Norway.
