Fourteen bay areas along the Texas coast won't begin oyster harvesting season on time because of toxin-producing red tide and excessive rainfall.
Oyster harvesting for the public typically runs November first through April 30th.
The Texas Department of State Health Services says 19 bay areas will open as scheduled on Wednesday.
Parts of Galveston Bay will be closed because of elevated rainfall.
Sections of Matagorda and Tres Palacios Bays won't open on time because of elevated bacterial counts.
Parts of San Antonio Bay and all of Mesquite, St. Charles, Aransas, Copano and Corpus Christi bays will remain closed indefinitely because of the presence of red tide toxins.
Red tide is a toxic algae bloom that can cause shellfish poisoning in humans.
Officials say the closed bays would be opened as soon as possible.
