Dennis,
Please look into the Abalone die off on the Sonoma Coast last August/September. Fish and Game is covering up the cause... saying it probably was some rare, never seen before toxic algae. Abalone eat algae and kelp. http://www.pintoabalone.org/Pages/pBiology.html

The radiation effects are being hidden by Fish and Game to protect the fishing industry. This is a huge story waiting to break as the collapse of building four will wipe out the entire Pacific Fishery.
Thank you for addressing this.
Lawrence
