From Alana:

For the past few weeks there have been numerous articles, editorials, and letters to editors in several local newspapers regarding open ocean aquaculture. A recent editorial in the Honolulu Advertiser states that 

the large size and experimental nature of the [Hawaii Oceanic Tech] project demands that state regulators, and the public, keep a critical eye on the project as it moves forward.

The article goes on to say that the objective of this project is an organic, ecologically sustainable fish. 

PROBLEM #1: Organic. The problem with this is that there are no organic standards for fish farming. It would also be especially hard to develop one for open ocean aquaculture, because the cages are not closed systems. Anything that is in the water will wind up in the bodies of the fish.

Hawaii Oceanic Tech also hopes to use “organic feed” for their fish. The main ingredient in HOTIs feed will be “sardines from sustainable fish stocks”. But, this goes back to what I said above: there are no organic standards for fish, so any claims of their feed being so are false.

PROBLEM #2: Ecologically Sustainable. This is a tricky one, just because it is so undefined. What is ecologically sustainable? Everything humanity does will impact the environment in some way. Perhaps ecologically sustainable means there is a balance of pros and cons for the environment. But what are the pros in this situation? Proponents of aquaculture say that farming fish gives wild populations a chance to repopulate, but this is easily proven wrong by the environmental havoc  that fish farming has caused in British Columbia and other places where fish farms are popular. Many Canadians are embarrassed that their government has let the caged farming industry expand because of its serious impacts.

Keep your eyes open for more aquaculture in the news in the coming weeks.

From Alana:

Entitled Aquaculture in Hawaii: Economic Advantage or Source of Sustainability, the Hawaii Venture Capitalist Association’s recent meeting addressed the benefits of many types of aquaculture in Hawaii. I think the presentation did a good job of explaining how aquaculture could be in Hawaii, in its most ideal form.

One of the first things mentioned was that aquaculture could help restore wild fish populations that are headed towards extinction. They failed to address, however, how that would happen. It is accepted in the scientific community that fish raised in fish farms are much less fit to live in the wild. Another weak point in the presentation was explaining how the current and future open ocean aquaculture ventures would increase self-sufficiency in Hawaii by reducing imports. Up to 90% of the future ventures’ fish would be exported, while the 10% allotted for Hawaii would go to restaurants like Alan Wong’s and Mariposa, restaurants that most people here can’t afford to go to on a regular basis.

There were also two slides that were completely skipped, clearly regarding genetics. I understand that this may have been due to time constraints, but the public deserves to know not only about possible economic gains from aquaculture, but also the genetic and environmental consequences of it.

A good way to sum up the outlook of the meeting is with the quote

“If it’s worth doing, it’s worth doing badly”

this quote was used during the presentation, but who is to say what is worth doing and what isn’t? Is anything worth doing badly anymore? A  commenter on one of m previous posts claimed that “fish poop” produced from aquaculture can curb the effects of climate change by absorbing the CO2 from the atmosphere, and adding it to the ocean. However, as my previous “ocean acidification” post details, an increase nutrient-rich fish effluent leads to the acidification of the ocean, thereby further risking the health of many ecosystems.

Once again, I urge everyone to learn more about what is going on in terms of aquaculture in Hawaii.
