Bay Oysters Have Good Year

State survey finds reproduction up, diseases and deaths down

The Chesapeake Bay's beleaguered oyster population spawned a bumper crop of babies last year, state officials announced Monday, and there are signs that the diseases that have ravaged the bay's bivalves for more than two decades might have loosened their stranglehold.

Gov. Martin O'Malley heralded the "exciting new evidence" from the state's recently completed survey of Maryland waters, adding in a statement that there is "reason to be more optimistic than ever about the recovery of this iconic species."

Others, while encouraged, were more cautious, noting that the bay's oysters have dwindled to 1 percent or 2 percent of their historic abundance, and that at least some of the apparent rebound may stem from favorable weather conditions over the past several years, which are unlikely to last forever...

 I'm with the cautious "Others".  I participated  in an annual oyster spat survey for several years in the late 80's and early 90's, and I recall that spat set varied widely between years, and that weather over the setting period seemed to be an important factor.  It would be nice if we could count on continued improvement, but I think that a trend longer than a year is required for much optimism.
