Because they are closed environment facilities, Green Oasis Foods farms can be built virtually anywhere in the world, relatively irrespective of climate and geography.
Realizing the significant opportunity for high tech organic aquaponic farming, Green Oasis Foods has moved from pilot testing to the first commercial facility in Delta B.C.
Our first Delta farm and those to follow will be developed to meet the increasing consumer demand for locally grown, organic leafy vegetables
Each state-of-the-art closed environment, 5,600 square metre (1.5 acre) farm provides the equivalent of 21.6 acres of traditional agricultural land. On an annual basis, each of these farms will produce 66 metric tonnes of 100% organic Rainbow trout in 40 rearing tanks, 326 metric tonnes of various organic leafy greens in 4 bio-secure vertical farming bays, and over 90 metric tonnes of high value vermicompost that can be used to revitalize depleted traditional farmland.
Aquaponics refers to any system that combines conventional aquaculture (raising fish in tanks) with hydroponics (cultivating plants in water) in a symbiotic environment. In normal aquaculture, excretions from the animals being raised can accumulate in the water, increasing toxicity. In an aquaponic system, water from an aquaculture system is fed to a hydroponic system where the by-products are broken down by nitrifying bacteria initially into nitrites and subsequently into nitrates that are utilized by the plants as nutrients. Then, the water is recirculated back to the aquaculture system. Green Oasis’ farms will use 95% less water per kilogram of food to grow and harvest produce compared to traditional farming.
The facility is subdivided into four bio secure zones. Each zone is comprised of a fish farm working symbiotically with five aquaponic raft towers for plant production.
Green Oasis Foods has implemented an aggressive Bio security regime, which sets parameters for the physical attributes of our farms and processes alike. Our farms are designed from the ground up to assure that pollutants, pests and disease are physically barred from entering. We also employ state of the art sensors and analytical controls to constantly monitor every stage of the processing and packaging stages.
Our plants start from Organic seeds. We grow them under Photobio LEDs for either 10, 21, or 42 days, depending on the crop. We seed our rafts with an automated machine, which also soaks the seeds to begin their germination. After spending their time floating on water in a carefully monitored growing environment, a Raft Retrieval system brings the rafts to a harvesting and packaging system to prepare the greens for shipping. We grow and package produce for the wholesale retail grocery, food service and botanical extracts industries.
Our fish start their aquaponics journey at the 'fingerling' stage when they are 10 cm long, in the first of three rearing tanks, for nine months. The transfers allow the fish to move into bigger tanks as they grow. Once grown to a weight of approximately 1.1kg, they are introduced to a specially designed tank to purge them for one week before they are harvested, processed, packaged and distributed. 66 metric tonnes of Rainbow Trout are produced annually.
