Farmed and Dangerous Can Hawai‘i mariculture avoid the pitfalls of fish farms elsewhere? Noreen Parks May 28, 2003 Honolulu Weekly Salmon. For years it’s been touted as an ultimate health food, a rich source of protein full of omega-3 unsaturated fats and other beneficial nutrients. Across the country, and here in Hawai‘i, you can find “fresh Atlantic” or “fresh Canadian” salmon in major food stores. Most consumers would be surprised to know that those slabs of pinkish flesh in Styrofoam packages come not from feisty wild fish, swimming free in cold northern waters, but from densely packed feed lots — “floating pig farms,” as Daniel Pauly, a fisheries expert at University of British Columbia, calls them. Around the world, the impacts of offshore aquaculture (or mariculture) provoke serious criticism and opposition. It’s been reported that the acres of open-ocean fish pens proliferating around the world have spawned voluminous wastes that contaminate local waters, drive whales and dolphins from their coastal habitats, and cause alarming declines in wild fish populations from Norway to Chile to the Mediterranean Sea. By competing with traditional fisheries, fish farms deprive fishers of livelihood. In exchange for sacrificing the health of their local waters and marine life, communities may gain some jobs, but the fish products often are exported to distant, high-value markets. Profits travel far afield, too. Despite claims that mariculture increases world fish supplies, raising carnivorous species such as salmon and finfish requires as much as 5 pounds of wild-caught fish for every 1 pound of farmed fish, according to a 2000 article in the prestigious science journal Nature by Rosamond Naylor, of Stanford University, and other researchers. The article documents the fact that catches of anchovies, sardines, herring and other small pelagic fishes have tripled in the last decade to supply food for farmed fish. Of course, this catch could itself feed people, or the bigger fish and mammals in the seas. Lessons from BC Now fish farming has come to Hawai‘i, with more of it planned. In 1999, the state Legislature rolled out a royal welcome mat for “sustainable” open-ocean aquaculture by amending the Ocean and Submerged Lands Leasing Act to allow private entities to obtain leases on areas of the ocean. The legislation failed to define “sustainable” — how will mariculture actually benefit the people of Hawai‘i or sustain our invaluable marine resources? — nor did it address the need for operations standards or environmental protection. And officials responsible for aquaculture under the Department of Agriculture have yet to establish policies for site selection, environmental monitoring and enforcement. With one fish farm operating off O‘ahu and two proposed, the state seems about to
