The Project:
Hawaii Ocean Technology’s (HOT) has been granted a Conservation District Use Application for its ahi aquaculture project. They plan to use 247 acres off the north Kohala coast of the island of Hawaii to hold 12 orb-like cages for growing tuna for export outside of Hawai'i.

The Problems:
- Fish Farming promotes the proliferation of antibiotic-resistant bacteria, which can infect humans.
The industrialization of aquaculture has resulted in many of the same environmental and human health problems currently created by livestock factory farms. In addition to polluting aquatic ecosystems with the enormous volume of waste produced by the fish they confine, aquaculture facilities threaten the environment and human health by releasing hazardous substances such as pesticides, antibiotics, and other drugs into the aquatic environment.
HOT fails to elaborate on potential health issues that may occur when thousands of fish are confined in a small space. Often, industrial aquaculture facilities address this problem by utilizing the same irresponsible antibiotics practices as industrial livestock operations; rather than reducing the density of fish, fish farms continuously administer sub- therapeutic doses of antibiotics. This promotes the proliferation of antibiotic-resistant bacteria, which can infect humans. The problem is exacerbated by cages and net pens allowing antibiotics and antibiotic-resistant bacteria to pass freely into surrounding waters.
- Farmed Fish Strip the ocean of fish for their feed
HOT states a 100 pound tuna requires approximately 200 pounds of dry feed. One thousand tons of feed stock per month will be required when fully operational by 2013 yet they admit that the specific components of fish meal and fish oil to be used as feed is at present unknown.

- Farmed Fish Breed Disease which is passed on to wild fish
The risk of disease transmission is increased when imported, unprocessed fish are used as feed therefore it is imperative to disclose what the components of this feed will be. Further, when feed accumulates on the seafloor, it is eventually decomposed by bacteria, which consume oxygen dissolved in the water and can thus create hypoxic “dead zones” below aquaculture facilities.
- Waste—The
Hawaii County Department of Research and Development states that the
project could generate as much as 2,000 tons of “offal” yearly
and asks for details in how it would be handled (page 13). HOT
replies (page 14) that “no waste will be introduced into the Big
Island landflls.” Where will it go? There is a suggestion that
ranchers may be interested in the byproducts. Will that pass
Department of Health muster?
- Lease cost—Two
existing aquaculture operations in Hawaii pay combined yearly lease
revenue to the state of $3500 (Hukilau/Cates= $1400; Kona Blue=
$2100). What percentage of $120 million expected yearly revenues
will HOT pay the state for exclusive use of 247 acres of ocean
resources?
- Noise—No
acoustic impact analysis report has been prepared to indicate what
combined effects noises in the 70-130 decibel range (page 7) would
have on marine mammals.
- Cage fouling—It
is unclear how algal fouling would be cleared from the cages (page
9). Would it be accomplished by divers tediously scrubbing the cages
on a daily basis, or by raising the tops of the cages to the surface
to “air dry” them for hours, as is done regularly by Kona Blue?
- Mortalities—Percentage
of dead fish to be removed from cages is estimated at 1% (of
20,000/cage). How is this estimate arrived upon, since this species
has not been raised previously in Hawaiian waters? What percentage
of “morts” would be tested for disease? How would 2400 dead fish
(with possibility of disease) be disposed of? Landfill? Incinerator?
- Size and scope—What
is the purpose of proposing such an enormous project despite, “a
multitude of untried and untested aspects of this project?”
(DAR, page 21-22). Other aquaculture ventures in Hawaii have
proceeded with conservative size and project scopes, yet HOT
proposes a lease area three times larger, with production scaled at
10-20 times more than Hukilau/Cates and Kona Blue. Why? HOT
continues to be vague on the expected yields of their project, by a
factor of 100%! They contradict earlier statements of 6,000 ton
(12,000,000 pounds) yearly production by stating (page 35) that
production will vary between 6,000 or 12,000 tons, “depending upon
the final system design.” That is an incredible amount of
uncertainty and wiggle room. One obvious discrepancy in their stated
impacts is it would then require twice as much fish feed (24,000,000
pounds) yearly for the greater yield.
- Public Trust Doctrine and Precautionary
Principle—Food & Water Watch
cited Hawaii Constitutional provisions in their August 27, 2009
letter (page 38). These seem every bit as relevant to the review of
the applications being sought as any other laws and rules cited in
the submittal, yet neither HOT nor staff responded to indicate they
were being considered or incorporated in any way.
- Engine design/Hybrid Solar Ocean thermal
Energy Conversion Power—The
propulsion system originally described in the DEIS subsequently
changed by the time the FEIS was issued, thereby denying the public
the opportunity to study its potential impacts. Staff notes that HOT
submitted the design to them on 9/9/09, meaning the public has not
seen it within the framework of legal environmental review, except
for in this submittal, only made available to the public four days
ago.
- Disease—There
is no discussion of how potential disease outbreaks in the cages
would be handled. A full mitigation plan must be discussed. Spread
of disease, pathogens, and parasites are major negative impacts that
have devastated caged and wild populations of fish globally, and is
one of the most dangerous side-affects of well-intended aquaculture
projects. See attached scientific
studies by Gaughan, Frazer (UH), and Tacon & Metian. All three
studies, and an attached article about the 85% collapse of Chilean
aquaculture stocks, describe catastrophic impacts spread by fish
farms.
- Fish food
It is acknowledged that the enormous amount of
food to supply such a large biomass of pelagic fish as proposed will
undoubtedly have impacts on the area where it is collected, grown,
and/or processed. Studies indicate that harvesting millions of tons
of baitfish (sardines, herring, anchovies, menhaden, krill, etc.)
worldwide greatly impacts regional ecosystems and competes with wild
fish populations’ ability to feed themselves (see: Tacon &
Metian).
Therefore, aquaculture operators are continually
seeking substitutes to feed their caged stock. Kona Blue has
substituted soy protein and chicken trimmings to offset percentages
of fish meal and fish oil. Top level piscatavores (fish eaters) like
ahi are not expected to have the same growth characteristics as wild
fish if they are fed land-based proteins. HOT acknowledges they,
“have not identified the best diet yet.” (page 44).
HOT gives a cut and paste answer throughout the
submittal that includes these quotes: “HOT will use a feed company
which is responsive to our exact specifications, and very transparent
about their feed ingredients and processing. At this time the vendor
to supply the fish feed has not been selected. So, the specific
components of the fish meal, fish oil is currently unknown. HOT has
no plans to use GMO soy. HOT will also seek to identify local
alternatives…” (page 35 et al).
Considering they are projecting the need for
12,000,000 pounds of feed annually, this language is incredibly
vague. There must be full disclosure and
understanding of the components of the fish feed, the sources from
which they are derived, and the impacts from withdrawing them and
importing those resources to Hawaii. Note that 100% of the feed would be imported.
On the same page, HOT claims, “No soy or grains
of any kind are expected [emphasis added] to be used as part of the feed. Ahi are carnivorous
(meat eaters) not herbivores (vegetable eaters) and the company
intends to use a fish feed that contains components consistent with
the usual Ahi diet and nutritional profile.” That seems to indicate
they would be using 100% ocean-based food, which again brings up
questions about cumulative impacts on bait fish stocks. and needs to
be clarified and conditioned.
Finally, how much space would be needed to store
these enormous amounts of feed? Is there existing facilities in
Kawaihae harbor to facilitate this/ How would vermin be kept from
moving in and contaminating the feed?
- Sustainability
HOT
repeatedly uses the term, “economically sustainable,” which
presumably means they hope to have revenues exceed expenses and be
financially successful. But it does not address using local resources
to create benefits for local people, without depending upon imports
and exports to balance the equation. 100% imports and 90% exports
does not equal sustainability.
- Economics
For
a proposal projecting such huge revenues, there is a shockingly small
number of jobs expected to be created. Half of these are for divers
and laborers. Furthermore, qualifying for Act 221 high tech tax
benefits means that a large chunk of state revenues would be avoided.
Detailed analysis of expected revenues through taxes and revenues
should be disclosed.
Exceptional
comments/quotations from the submittal document
“Farm
the ocean like we farm the land.” (page 16) The problem with this idealized notion is that this is not
a farm; it is an industrial feedlot. As such, problems are similar to
factory feedlots for cattle, chickens, or pigs—pollution,
pathogens, disease, and the need for antibiotics.
“Marine
aquaculture has been well tested, is sustainable, and will create a
better product.” (page 19) For those
who may believe in this Pollyanna-ish view, I strongly suggest they
read the book, “Swimming in Circles.” (Molyneaux)
“The
fisherman (sic) of the world can become farmers.” (page 20) (see above)
“In
other words, fish poop may be good for the oceans.” (page 35) How much?
“Commercial
output is still a long way away.” (HOT-page 40) Then why the rush to approve this enormous project
while questions remain unanswered?
“Staff
notes the proposed project seems to be more science fiction than
reality.” (page 57) It seems unwise to
base real permit approvals on so many uncertainties.
Recommendations
Address
all unanswered questions, economic, scientific, cultural and
environmental concerns and inconsistencies through further research,
dialogue, and outreach. Assure the vested rights of Big Island
residents to have a bona fide voice in the process by scheduling
meetings in West Hawaii. Be certain of the ability to mitigate
potential problems and impacts before approving permits to allow the
proposal to move forward. As Eden Peart of the Hawaii Farmers Union
stated (page 33), “The proposal should not be considered without
educational outreach and public hearings.”
Merely
to cite ocean fishery mismanagement and plummeting populations of
fish species worldwide to justify open ocean industrialized fish
feedlots to be constructed is an impetuous approach. Great caution
must be taken as we move to create better models for local food
production. It is entirely possible that there is greater merit and
much more potential for sustainability in reviving historic Hawaiian
coastal fishponds, or in pursuing land-based recirculating
aquaculture and aquaponics systems that utilize nutrient-rich fish
waste to grow vegetables.
