Galveston's Red Tide Appears to Have Dissipated, Oysters Recovering
On January 27, two small portions of Texas Gulf waters were conditionally opened to shellfish harvesting after a red tide epidemic forced the indefinite closure of oyster season in October.

San Antonio and Espiritu Santo Bays were approved by the Texas Parks and Wildlife Department for commercial oyster harvesting, while the Texas Department of State Health Services closely monitored the waters for remaining signs of this year's devastating red tide.
Cautiously optimistic news came yesterday from Jim Gossen, owner of Louisiana Foods and oyster expert, who stated that the red tide appears to have finally subsided.
"It appears that, as of the end of last week, the red tide in Galveston Bay has officially dissipated," Gossen wrote. He was quick to caution, however, that this does not mean that Texas Gulf waters are now fully open for oyster harvesting.
"No higher than acceptable readings were found anywhere in Galveston Bay last Thursday or Friday," Gossen reported of the red tide's toxins, which are produced by an overabundance of algal bloom. In the Gulf of Mexico, the algae responsible for red tides is Karenia brevis, algae that occurs naturally in the ocean.
In normal periods, the algae is present in much lower concentrations and poses no threat to marine life. During a drought, like the one Texas just experienced, a red tide can and often will occur as the result of a lack of fresh water flowing into increasingly salty Gulf waters.
