From Alex Nunez
Red Tide Status Update
Reporting Period: October 26 to October 30 @1000 Texas Parks and Wildlife Department is working with other agencies to monitor a red tide event along the southern Texas coast. The bloom was first confirmed on Sunday, September 13, by the University of Texas Marine Science Institute who collected samples around the fish pass jetties on Mustang Island due to strong aerosols. Water samples collected and analyzed for Karenia brevis densities are given the following designations: Background = Less than < 1 cell/ml Very Low = 1 to 10 cells/ml) Low = 10 to 100 cells/ml Moderate = 100 to 1,000 cells/ml High = Greater than 1,000 cells/ml
Regional Updates
On 10/29/15, TPWD staff conducted an overflight along the gulf coast from Galveston to Pass Cavallo and Matagorda Bay. No K.brevis bloom or dead fish observed.
Upper Coast (Sabine Lake, Galveston Bay, East Matagorda Bay, Matagorda Bay):
Water Samples
Gulf of Mexico
TPWD Gulf trawl surveys out of Sabine Lake area observed no indication of red tide. Observations included no aerosols, no dead or distressed fish, and no indication of discolored water.
TPWD Gulf trawl surveys out of Galveston Bay area observed no indication of red tide. Observations included no aerosols, no dead or distressed fish, and no indication of discolored water.

TPWD Gulf trawl surveys out of the Port O'Connor area observed no indication of red tide. Observations included no aerosols, no dead or distressed fish, and no indication of discolored water.
Water samples collected for K.brevis by PINS ranged between very low to moderate. Samples collected included high amounts of lysed cells due to high wave action.
San Antonio Bay
Water samples collected for K.brevis by TDSHS in San Antonio Bay area indicated high concentrations in Espiritu Santo Bay, apptox one half mile west of dogleg in Army Channel. Distressed menhaden was also observed.
Aransas Bay
No new updates during this reporting period.
Corpus Christi Bay
Streaking continues to be observed along the southern section of Corpus Christi Bay along the Corpus Christi bay front. Discolored water was present along the Nueces Causeway as well.
While conducting routine monitoring sampling TPWD staff observed discolored water near the Ingleside area.
Upper Laguna Madre
Water samples collected for K.brevis by PINS indicated very low concentrations at Bird Island Basin.
Fish kills
Gulf of Mexico
Reports of distressed menhaden were observed in the Aransas Pass area.
Reports of distressed menhaden were observed near Packery Channel area.
San Antonio Bay
On 10/28/15, shrimp tissue collected on 10/9/15 from a commercial fisherman by staff was submitted to TAMU-CC, Center for Coastal Studies for brevitoxin analysis.
Aransas Bay
While conducting routine monitoring sampling TPWD staff observed no aerosols, no predating gulls, and no floating or distressed fish around Mission Bay, Copano Bay, Aransas Bay, Mesquite Bay and Cedar Bayou.
Corpus Christi Bay
While conducting routine monitoring sampling TPWD staff observed no aerosols, no predating gulls, and no floating or distressed fish around the Ingleside area or the Shamrock area.

Water samples collected by the Red Tide Rangers along the beach of South Padre Island indicate low to moderate concentrations.
Lower Laguna Madre
Water samples collected for K.brevis by the Red Tide Rangers around the Brazos Santiago Pass area indicate moderate concentrations.
Water samples collected for K.brevis by the Red Tide Rangers north of the Queen Isabella Causeway indicate low concentrations.
Fish Kill
Gulf of Mexico
No new updates during this reporting period.
Lower Laguna Madre
While conducting routine monitoring sampling TPWD staff observed no aerosols, no predating gulls, and no floating or distressed fish about 10 mi south of the mouth of the Arroyo Colorado and 4 miles east.
A report of a menhaden kill observed near the swing bridge in Port Isabel. _________________ Like Corpusfishing.com on Facebook! |

Pretty sure they mean cells that have been disrupted due to winds and waves, which causes the release of the aerosols and foam and what not. _________________ "I never had an Easter, but I've always had a bunch of speakers" - Beardo |

A lysed cell is a cell that has ruptured without destroying the contents. This is the main way the Brevia kills fish. When the cell is lysed it releases a toxin, a secondary metabolite, that is toxic to the fish which causes the problem. Brevia are very fragile and are easily damaged by surf. |

When the cells are growing good they are like a balloon and the toxins are inside and not a problem. When the cells lyse, the balloon pops and out comes the toxin to cause problems. |
