A colorful sea star has vanished from the Pacific Ocean off California and Oregon, and its nemesis, a voracious kelp-eating urchin, has run amok. And the consequences for the area’s marine ecology and California’s fishery has been catastrophic.
Across the worlds oceans, sea urchins are on the march and thats not a good thing. Reports on how a new system of population management can stem a damaging swell in numbers while meeting a growing demand for their you-know-whats.
Federal scientists and others are exploring the possibility of sea urchin farming in Canada, with at least six pilot studies using Norwegian technology that proponents hope will turn "zombie" urchins which can denude kelp beds into profitable seafood.
