The AgriMarine System™ Terminology

Eliminating or reducing the need for antibiotics or pesticides

Fish health is optimized by proper husbandry from the egg selection through to harvest. Salmon thrive in the controlled environment within the AgriMarine System™. The constant flow of new water at a comfortable temperature, with constant supplementation of oxygen combined with the lack of external stressors such as poor quality water and predators ensures that the rearing environment is excellent for our stocks. This in turn reduces or eliminates the need for antibiotic treatments.

Pesticides would typically be used to reduce the prevalence of sea lice populations in the captive salmon population. Some studies have shown that sea lice that affect salmon do not occur, or have very low populations in deep water. There is also evidence that moving oxygenated water repels sea lice. The AgriMarine System™ draws water from depth, thus avoiding the upper trophic regions in which sea lice thrive. The in-tank water is oxygenated and constantly refreshed.

Implementing waste removal processes

Current farming methods allow waste to collect on the sea bed, fouling the ocean and attracting a series of flora and fauna that culminates in larger animals such as seals and sea lions being attracted to the sea farm tenure. The AgriMarine System™ removes fecal material and unconsumed feed through a waste separator, through our proprietary Nutrient Recovery System. This waste may be used as land-applied fertilizer to grow other land raised food crops and provide secondary economic benefits such as jobs and a tributary revenue stream.

Increasing fish feed efficiency

The AgriMarine System™ encourages increased metabolism and efficient use of nutrition provided by fish feed, through its optimization of the rearing environment. The constant gentle movement of water allows the fish to swim as they would in nature – this results in flesh quality similar to wild fish – and the fish feed is carried around the tank until eaten, simulating natural feeding patterns.  We have and will continue to conduct feed trials, with the aim of enhancing solids capture.

Lowering operating costs

Maximizing fish health

The AgriMarine System™ is designed to draw water from depth and remain in constant circulation with real time monitoring of life-support systems. In essence, our system provides optimum rearing conditions year round, resulting in healthier fish with faster growth rates.

Preventing fish escapes

Fish escapes are problematic from both ecological and farm management perspectives. When fish, particularly non-indigenous species, escape they compete for food and potentially for spawning grounds with indigenous species. As well, due to habituation, farmed fish tend to stay close to the cages where they’re used to being fed and this in turn attracts predators which then leads to attacks on the remaining contained fish. From a farm management perspective, the loss of fish to the ocean environment has a direct impact on revenue. The AgriMarine System™ provides a barrier that lowers the risks of escapes and predator attacks, thus allowing the farmer to concentrate on rearing the fish.

Utilizing energy more efficiently

The AgriMarine System™ exploits naturally occurring water temperature stratifications through a dual intake system, allowing the operator to manipulate and optimize in-tank water temperatures. In the summer, when surface temperatures can be high enough to kill off fish inventory, cooler water may be drawn from depth to mitigate the negative impacts. In the winter, when surface temperatures may create a layer of ice, warmer water may be drawn from the temperature inversion to allow ice free surface water and the continued feeding of fish year round.
