Thousands Of Dead Fish In Iceland

i bet some whales or large school of predator fish, maybe cod, chased them into the inlet, the tide went out, the fish get stuck and died, to say bridge construction caused it is not believable. i have driven through 8 inches of dead fish off cape cod, for over 1/2 mile long, we got stuck in the fish there were so many,the bluefish chased them in and they got stuck,high tide then tide switched it was a horrible stinky mess, it happens, good to see alot of herring, sad to see them die. the giant trawlers are worse of a problem
