Treated Wastewater May be Safe for Aquaculture

Although aquaculture in treated wastewater is practiced worldwide, there is scant scientific research concerning whether organic micropollutants are present at safe levels for consumption.

A new study in Aquaculture by researchers at Ben-Gurion University of the Negev has determined that organic micropollutants in the water—trace elements of heavy metals, pharmaceuticals and personal care products as well as pesticides, solvents, and detergents—result in minimal accumulation in fish. Additionally, the wastewater does not appear to affect other commercially important traits of fish.

Will San Diego Aquaculture Bring Back Abalone?

Port officials looking to expand local aquaculture heard some good news this month. A two-year project by federal scientists that mapped the potential for aquaculture in the U.S. found ample promise in San Diego. And zeroing in on those spots is getting easier. “We think this is the most exhaustive analysis ever done at the estuary scale in the U.S.,” said James Morris, a marine ecologist with the National Oceanic and Atmospheric Administration who presented the results to the Port.
