Saw this article in NJ.com that blames the issue on predatory fish like bluefish and stripers chasing the bunker into shallow ares where they exhaust all of the oxygen and die off. I could buy that story if it was May and there were a lot of stripers and bluefish around but not this time of year. Somethings fishy here!
