Back in the 60s I was in the Fish& Wildlife service and I spent a lot of time on the piers of different Maine towns. Many fishermen hung out there and talked about the problems of the fishing business.

I overheard one grumpy old goat saying to another, "Now that that f*****G Kennedy has decided that the niggers are as good as us, we will never sell another Maine sardine."

The real problem of course was over fishing. When the Soviet fleets came to the gulf of Maine with their huge factory ships and trawlers that were designed to take everything in sight, including spawning Herring, that was the beginning of the end.
Then came the Spanish pair trawlers with nets so big it took two of them to drag them.
