MA13 not closing for just low population of dungies, DOH water quality program has shown for the last 3 years that the PH balance is shifting towards the acidic, paired with that tests have shown the crabs are "soft" and starting to have a hard time creating a thick hard shell.
With the Salish Sea not flushing it's water like it used to with free flowing rivers and more and more people living around it, failing septics, cities dumping sewer straight to the bay (for any reason), road runnoff, agricultural runnoff blah blah blah blah. ...if MA13 goes acidic officially others will be close behind and a bevy of issues unlike we have ever seen will be upon us.
