Aquaponics is the combination of aquaculture (raising fish) and hydroponics (the soil-less growing of plants) that grows fish and plants together in one integrated system. 

Here is where the perfect synergy of aquaponics happens:

  • The waste of fish enriches the water with many mineral compounds.
  • Water is circulated through a biofilter - essentially a colony of nitrifying bacteria which turn ammonia and nitrites into plant-nurturing nitrates.
  • Plants consume excess nitrates for growth
  • The water is then filtered back and returned to the fish tank.

The primary benefits to Aquaponics are:

  • Environmentally responsible with low water usage and low power usage.
  • The primary inputs to the system are Fish food and water.
  • Little to no Chemical usage. Aquaponics requires no synthetic fertilizers and few pesticides.
  • Many of the plants that thrive in Aquaponic growing are very easy to grow.
  • Low susceptibility to pests and diseases.
  • Timely crop turn around
  • Increased crop production per square foot versus traditional farming
  • Multiple crops and fish can be grown from the same system
  • Fish can be harvested as an additional food or revenue source

 The cycle goes on, producing high yields of both fish and vegetables through this sustainable system.
