HOW IT WORKS

OASYS System Overview

What is Aquaponics?

Aquaponics is an incredibly efficient  and sustainable system of agriculture that combines hydroponics (growing plants in water) with aquaculture (raising fish).

​

Aquaponics works by creating a small ecosystem where fish and plants help each other grow. Fish are kept in a tank, and their waste is filtered and converted into nutrients for the plants. The nutrient-rich water is then pumped to the plants growing in separate beds. The plants use these nutrients to grow, filtering and cleaning the water in the process. This clean water is then cycled back to the fish tank, creating a continuous loop. 

​

This innovative approach significantly reduces water usage, up to 90%, compared to traditional farming, as the water is continually recirculated within the system, minimizing waste. The symbiotic relationship between fish and plants also eliminates the need for chemical fertilizers. Aquaponics can be implemented in various environments, including urban settings and areas with unfavorable climates or soil quality where traditional agriculture would not work.

 

Aquaponics systems promote faster plant growth and higher crop yields, contributing to food security and making fresh, local produce more accessible to any community. Many nutritious fruits and vegetables can be grown in an aquaponics system including tomatoes, peppers, cucumbers, strawberries, lettuces, green onions, kale, Swiss chard, herbs, and spinach. In addition, the fish can also be harvested and eaten.

OASYS System Specs

These are the basic specs for the system. These numbers have been calculated on a system that grows lettuce and leafy greens, so please be aware that length of grow cycles and produce quantities will vary by crop.​ Energy usage will also vary by region and equipment.

Produce​

  • 6 grow beds that are 4 ft 4 in wide x 31 ft long / 1.32m x 9.45m.  

  • 805 sq ft/ 74 sq m of grow space

  • 600-750 plants will be ready for harvest each week.

  • 8-9 week average grow cycle for leafy greens, meaning it takes 8 or 9 weeks from when you plant the seed to when you harvest the plant.

  • 8,000 lbs or 3,600 kgs of harvested lettuce each year.

​

Fish and Water​

​

  •  The system is a Deep Water Culture system which means the plants are suspended in floating rafts in water-filled grow beds that have 10in/ 25cm of water in them.

  • 7,000 gallons / 26,000 liters of water is recycled continuously through the system.

  • 360 fish in the system, divided between three,  275 gallon /  1, 040 liter IBC tanks. 

  • 540 lbs / 245 kgs of fish can be harvested each year, which provides a complete yearly supply of protein for a family of four. 

​

Energy and Time

​

  •  Power usage is approximately 24 kWh a day to operate two water pumps and one air blower.

  • Approximately 20 hours/week to manage the system

  • 10-20 hours/week for business management
