Farming with fish, not soil at a new Goleta farm

Written by


A new farm in Goleta is using a method of farming called aquaponics to grow nutrient rich, leafy greens.

“It’s a marriage between aquaculture, which is the raising of fish, and hydroponics, which is growing plants in a nutrient rich water solution,” said Clayton Garland, who co-owns Eco Conscious Aquaponics along with Julian Cantando. The two met while taking a horticulture class at Santa Barbara City College, and started their business shortly after.

You can now find them at the Saturday farmers market in Santa Barbara and the Sunday market in Goleta. KCRW met up with them at the market to learn more.

How aquaponics works

Goldfish (Julian Cantando)

Catfish, Koi and Goldfish swim in big tubs of water. The waste produced by the fish supplies the nutrients for the plants. In turn, the plants purify the water for the fish by absorbing and filtering the water.

Garland and Cantando stick to growing leafy greens like red vein sorrel, parsley, celery and watercress. Root vegetables are harder to grow without soil.

“The plants are getting 100 percent irrigation all the time, said Cantando. “The roots are constantly in the water and getting the nutrients they need. There’s never any stress so we get this really beautiful and flavorful product at the end.”

The system is re-circulatory, which means water never leaves the system unless through transpiration (loss of moisture through the plants’ leaves), evaporation or harvest.

What to make
