Seafood, wild or farmed? The answer may be both
Date:8/6/2012

(Santa Barbara, Calif.) Most people think of seafood as either wild or farmed, but in fact both categories may apply to the fish you pick up from your grocery store. In recent years, for example, as much as 40 percent of the Alaskan salmon catch originated in fish hatcheries, although it may be labeled "all wild, never farmed."

An article produced by a working group of UC Santa Barbara's National Center for Ecological Analysis and Synthesis (NCEAS) recommends that when a combination of seafood production techniques are used, this be acknowledged in the marketplace. The group calls on national and international organizations and governmental agencies to use the term "hybrid," when applicable. The article is in press with Marine Policy, and is currently available online.

"Farming fish and shellfish is generally a different way to produce seafood than fishing," said Dane Klinger, first author and a Ph.D. student at Stanford University. "While fisheries traditionally interact with their target population only at the time of capture, aquaculture, in its 'purest' state, controls the entire lifecycle of the organism, from egg to harvest. However, many common types of seafood are produced using techniques from both fisheries and aquaculture."

Mary Turnipseed, second author and a former postdoctoral fellow at NCEAS, commented: "Seafood production is a critical part of global food security, but the way we study and talk about it often obscures how to achieve the thing we care the most about: increasing the supply of sustainably produced seafood to feed a rapidly growing human population. We need to start collecting more accurate data on how seafood is really produced in today's world, and a first step will be through replacing the old farmed-fished dichotomy with a farmed-fished-hybrid classification scheme."

The article reveals how the strictly traditional categories of seafood production fisheries and aquaculture are insu
