Fish Farming

Following up on yesterday’s post, here is another story of an attempt to farm fish in California, as reported by the Los Angeles Times.

An excerpt.

“Greenhouses once ruled the Pajaro Valley on the Central California coast, where the local cut-flower business found success worldwide.

“Empty nurseries now dot the area, a sign of the industry's decline. But with the help of plenty of water, Chris Newman, 58, hopes to restore the glory of greenhouses.

“His tactic is called aquaponics, a combination of aquaculture — fish farming — and hydroponics — growing plants in water. With the help of neighbors and his brother Tom, Newman has converted 14,000 square feet in a former rose-growing facility into a system of stream channels, gravel beds and water pipes where he hopes to soon raise fish and grow vegetables commercially.

"I'm pushing the envelope here, but I think this is something that's bound to take off," said Newman, who grew up in the Pajaro Valley, leaving only to launch a brief but successful career writing mystery novels in New York.

“In recent decades, aquaponics has become an increasingly popular backyard pursuit, though its commercial application has been limited.

“Just a few aquaponics businesses currently operate in the country, said Rebecca Nelson, editor of Wisconsin-based Aquaponics Journal. But the number is on track to grow.

"Farmed fish is really where we're going as far as what we'll have access to," she said.

“Aquaponics evolved from the desire to harvest fish rather than put stress on dwindling wild fisheries and grew to use the extra water for crops, Nelson said. The method's toll on the environment, compared with other ways of farming fish and vegetables, is minimal.

"People here care about food ingredients and where they're sourced," Newman said. "Every 27-year-old kid in San Francisco now has a food blog."

“Newman, who has hired a marketing manager to develop his sales strategy, already has a name for his venture: Santa Cruz Aquaponics.

“In his rented greenhouse, he's dug 40-foot channels for fish such as catfish. Above those are two stories of gravel beds where vegetables will grow — initially watercress but perhaps others in the future.”
