Protecting the “Most Important Fish in the Sea”
(Posted by Gerald Winegrad.)
Conservationists have been working for seven years to gain conservation measures for menhaden. This species plays an important role in the Chesapeake Bay’s ecosystem as a filter feeder, as a critical prey species for other fish and for piscivorous (fish-eating) birds. That’s why this keystone species has been called the most important fish in the sea.
After the Atlantic States Marine Fisheries Commission 2010 stock assessment found that menhaden are at their lowest point on record, the group is on the brink of adopting historic coast-wide conservation measures for this over-fished species. Yesterday, a group of 30 Chesapeake Bay leaders sent this letter to ASMFC urging restrictions on fishing this critical species.

With the watershed states (Maryland, Virginia, Pennsylvania, New York, W. Virginia and Delaware) and D.C. working to significantly reduce pollution to meet the Chesapeake Bay TMDL, nutrient trading is a hot topic. Some see trading as a way to reduce the challenging costs of Chesapeake Bay cleanup, and it looks good on paper—but there are serious scientific concerns about its practicality and water quality benefits, particularly with trades between nonpoint sources (like agriculture and stormwater runoff) and point sources (like wastewater treatment plants). Difficulty in accurately measuring trading’s effectiveness also seems like a big obstacle.

Before Henry David Thoreau borrowed an axe and withdrew to the woods at Walden Pond, he spent a great deal of time daydreaming of owning a proper farm. He writes that “at a certain season of our life we are accustomed to consider every spot as the possible site of a house.” Toward this end, he had “surveyed the country on every side within a dozen miles of where I live. In imagination I have bought all the farms in succession.” He imaged how he would transform the land “into orchard, wood-lot, and pasture” and decided “what fine oaks or pines should be left to stand before the door.”
It seems that no one, not even the sage of Walden Pond, can escape from the pull of home ownership. In many ways it is the American Dream—white picket fence, grassy lawn, dog rolling in autumn leaves, every home a castle and every homeowner the king or queen of their castle. Entire television programs—no entire television networks—are based on the premise of buying, building or rebuilding the perfecting home (e.g., “House Hunters,” “Property Virgins,” “Curb Appeal,” and my favorite, “Flipping Out”—who can resist Zoila?).
