Yes, that's probably the case. I used to fish off of Eastney beach in Portsmouth. There is a pier there with a sewage pipe running underneath. It used to be a great fishing area but since they moved the pipe to a more offshore location to help clean up the beaches, it's been crap.
Along the same lines as the cockles there is another instance of decreasing fish stock. This time the humble Flounder is suffering in our local harbours, but not from pollution. This year has been terrible for flounders and is thought to be because of the nursury areas brought in several years ago to protect the Bass stocks. Aparently the increase of shoal bass has wiped out the Flounder fry.
I guess that they will make a recovery in years to come.
