Aquaculture has potential to cut poverty, combat food insecurity – UN report
Increasing Demand
What is Recirculating Aquaculture?
Closed Containment Solution
The United Nations Food and Agricultural Organization projects that a 100% increase in fish farming, is necessary over the next ten years to maintain current demand.

Without growth in the aquaculture industry, the world will face a seafood shortage of 150 million tons by 2025.

Traditional fish stocks have collapsed in nearly one-third of all sea fisheries and the rate of decline is accelerating at the same time that demand is growing.
Recirculating aquaculture systems (RAS) operate by filtering water from the fish tanks so it can be reused within the tank. This dramatically reduces the amount of water and space required to intensively produce seafood products. The steps in RAS include solids removal, ammonia removal, Co2 removal and oxygenation.
Aquaculture Daily
The US is the leading global importer of fish and fishery products, with 91% of the seafood we eat originating abroad - half of which is from aquaculture
Net Pen
Increased supplies of organic matter from uneaten food and feces leads to algal blooms. This, along with the decomposition process leads to oxygen depleted dead zones
Spread of Disease
Incubation of local diseases and parasites have caused collapses of wild fish populations
Introduction of Alien Species
Fish escapes of genetically modified or non-native species have polluted the natural gene pool
Antibiotics, hormones, pigments, herbicides, parasiticides and antifouling agents used in aquaculture pose environmental and food safety issues
Benefits of RAS
Protection from parasites and disease
Eliminates the use of vaccines, antibiotics and pesticides
Controls and treats all waste material
High in nutrients, the waste can be utilized as a valuable organic fertilizer
Generates weekly harvests providing stable supply of fresh product
Accelerated growth rates
Provides secure working conditions for staff
Farms can be located anywhere
Feed Crisis
Fishmeal Alternatives
Soybean Meal
Corn Protein Concentrate
Bone Meal
Feather Meal
Breakthrough in Fishmeal Replacement
From Waste to Feed
During a fishing trip, well-known geneticist and environmentalist David Suzuki pondered the sustainability of aquaculture diets with entrepreneur Brad Marchant. Brad asked him, "what would be better?" David pointed to the end of his fishing pole and said, "why not insects?"
