Grist Needs to Dig Deeper on Industrial Fish Farms
By Mitch Jones
Today, our friends over at Grist published a story about the attempt to bring open ocean aquaculture, that is, industrial fish farms, to U.S. territorial waters. The story is based on a recent press release from Kampachi Farms trumpeting their recent attempts to demonstrate the viability of drifting cages in the open ocean.
Unfortunately the story leaves out many of the questions that surround this project…
First, while the story says the purpose of the Velella Project was to show that the cages could operate in open waters, the cages have been seen only four miles off the coast and have attracted wild species that would normally be fished. The presence of these cages will likely have a negative impact on local fishermen’s ability to catch fish, not only because they attract wild fish, but also because of the harm they could cause to the local marine environment.
Second, fish escapes and equipment loss can also reap havoc on the environment immediately surrounding fish farms. In the summer of 2011, Kona Blue Water Farms reported that they lost two of their empty net pens while towing them out to sea, as the Grist story mentions. What is left unsaid is that the whereabouts of one of these cages is unknown. Attempts to sink it failed and it may still be floating at or just below the surface of the water creating a potential hazard for shipping activity. No environmental study of the impacts has been conducted on the sinking of the second cage.
Third, despite initial claims that the project would produce 2,000 fish at 8,000 pounds total, the company’s release is completely silent on how much fish was produced, leading us to question how much of a success it actually was. The public has a right to know all the facts. After all, the project was partly funded with U.S. tax dollars: $500,000 from the National Science Foundation and $242,889 from National Marine Fisheries Service.
Finally, if this project was a much of a success as the company claims, and is reported in this story, how come the next phase of the project will use anchored cages? If the project successfully proved the viability of drifting cages, why won’t the cages be drifting any longer? And, if the next round of cages are anchored, what does this mean for the supposed environmental benefits of having the cages drift? Surely anchored cages will not lead to the wide dispersal of fish waste promised by this project.
Instead of providing a solution, the Velella Project raises serious problems with the concept of open ocean aquaculture. To learn more about the decade-plus track record of setbacks and failures in open ocean aquaculture read our report Fishy Farms.
