The tragedy of the commons requires that fisheries be managed, somehow. The ways to do it can be debated, but there is no doubt that the conservation measures for Striped Bass have resulted in a remarkable resurgence of their populations (along with cleaner breeding waters in their rivers and bays).
In recent years, factory ships have, in just a few years, stripped the Northeast of our vast schools of Bunker (Menhaden) with the use of helicopter spotters. Those schools are foundational to our big fish.
The fishing industry of the Northeast US cleaned out the George's Bank populations years ago, pretty much emptied out the inshore Cod and Haddock populations, and is headed in the same direction with the Grand Banks. Furthermore, their trawls vacuum the sea bottom of every living thing, leaving a desert behind. Like strip-mining.
While I admire professional fishermen very much for their skills and daring, just as with hunting wild animals there have to be sustainable limits or the Cod would go the way of the buffalo and the Passenger Pigeon.
We posted about Atlantic Shad yesterday. Here's an article discussing why the once-great Hudson River Shad fishery was shut down a few years ago.
