After a weeklong respite, state scientists are currently killing the second rush of sea lions that have ventured out to the base of the tumbles to crunch on another salmonid species, the spring chinook.

The spring chinook run is additionally recorded under the Endangered Species Act and scientist gauge ocean lions are eating up to 9 percent of the returning grown-ups each spring, Clements added. Up to 40 ocean lions are going after the chinook, he stated, while just 12 were pursuing the steelhead.
