New study raises concerns about proposed mitigation strategy for marine bycatch
Date:6/17/2008

SANTA CRUZ, CA--Huge numbers of fish, seabirds, and other marine animals are routinely killed and discarded after being inadvertently caught during fishing operations. Known as marine bycatch, this problem is an ongoing challenge to the fishing industry, regulatory agencies, and conservationists. One recent proposal would compensate for bycatch by reducing other impacts on affected species, but a new analysis suggests that this strategy could end up doing more harm than good.

A paper published last year in Frontiers in Ecology and the Environment made the case for "compensatory mitigation" of fisheries bycatch, using seabird deaths caused by a longline fishery as an example. The authors suggested that eradicating rats from an island with seabird nesting colonies could have more benefits for a population of shearwaters than efforts to reduce bycatch in the longline fishery.

A number of seabird experts, however, were skeptical of the paper's findings. Given its potential influence on fishery policies, they decided the proposal warranted a careful evaluation.

"There are so many complexities involved in fisheries bycatch, we felt compelled to thoroughly examine the strengths and weaknesses of this approach and establish the criteria that would have to be met for it to work," said Myra Finkelstein, a postdoctoral fellow in ecology and evolutionary biology at the University of California, Santa Cruz.

Finkelstein is the lead author of a paper published June 18 in the journal PLoS ONE that evaluates the potential effectiveness of compensatory mitigation for marine bycatch. She worked with a dozen coauthors whose areas of expertise include seabird conservation and ecology, marine bycatch, and mathematical modeling of wildlife populations. The researchers concluded that compensatory mitigation could only rarely succeed in reducing or offsetting the effects of marine bycatch.

"It's very difficult to make this work,"
