Oyster fishermen worried about problem area along the coast, WWL-TV, January 25, 2011:
"It's not a good sign," said John Tesvich, chairman of the Louisiana Oyster Task Force. The sign is a lack of oyster spat, in what is known as coastal zone number two. Scientists are baffled, and they said so at a meeting on Tuesday of the Oyster Task Force.
"That's really alarming, when we see large areas, some of the areas that are the heart of the predominant oyster seed ground, we're not seeing the young spat this year," Tesvich said. ...
The lack of spat is now a real worry. At this point, it is not clear whether fresh water diversions -- from Caernarvon and other areas -- have anything to do with it. That's because areas that are even further away from the coast are also seeing the same spat problem.
"The outer reefs, further out, where the salinity would be considerably higher, should have had some spat signals. But we don't see it anywhere, and that's really tough," Tesvich said. "Normally after a fresh water event, the crop rebounds. We may even have bumper crops. That's traditionally been the general sequence of events, but we haven't seen that and nobody really knows why."
