Deepwater aquaculture can it be sustainable

Deep-water aquaculture has been trailed off sure Hawaii since July 2011, large unanchored pen stocked with 2000 hatchery-born fish known as kampachi, has been monitored by a team of marine biologist from the aquaculture company Kampachi Farms. The project known as Velella Project led by industry pioneer Neil Sims is the first attempt at commercialising offshore aquaculture in the United States.

To hold the fish, Sims used a specially designed structure called the Aquapod. Its unusual sphere-shaped design helps reduce fish escapes called “leakage” by the industry and can withstand tough ocean conditions. The kampachi are native to Hawaiian waters, and travel in schools by nature. If fish escape, they tend to cluster near the pen, and avoid the open blue water. A native species also eliminates the risk of cross-breeding. “The Velella beta test showed us that the biological performance of fish in a drifter cage system is astonishing,” says Sims.
