Speed trap for fish catches domestic trout moving too slow
Date:3/10/2014

PULLMAN, Wash.Washington State University researchers have documented dramatic differences in the swimming ability of domesticated trout and their wilder relatives. The study calls into question the ability of hatcheries to mitigate more than a century of disturbances to wild fish populations.

Kristy Bellinger, who did the study for her work on a Ph.D. in zoology, said traditional hatcheries commonly breed for large fish at the cost of the speed they need to escape predators in the wild.

"The use of hatcheries to support declining wild salmon and steelhead is controversial," said Bellinger. "They have a role as being both a part of the solution in supplementing depleted stocks and as being a hindrance to boosting natural populations, as they often produce fish that look and behave differently from their wild relatives."

Bellinger conducted the study with Gary Thorgaard, a nationally recognized fish geneticist and professor in WSU's School of Biological Sciences, and her advisor, Associate Professor Patrick Carter. Their work is published in the journal Aquaculture.

The study used a sort of speed trap for fish, a meter-long plastic tank filled with water and fitted with electronic sensors. Over 10 weeks, Bellinger repeatedly ran 100 clonal (genetically similar) hatchery-raised and semi-wild rainbow trout through the tank, clocking their speed and monitoring their growth from week to week. The clonal rainbow trout were propagated on the WSU campus.

The domesticated fish tended to grow faster. But while increased size is generally seen as a sign of fitness, the researchers saw that wasn't the case as far as speed is concerned. "The highly domesticated fish have bigger body sizes but slower swim speeds compared to the more wild lines that are smaller," said Bellinger. "It is intuitive to think that the more you feed them, the more they're going to grow, the faster they're going to be, and that's what we see withi
