In the Gulf, this species occurs throughout estuaries, shallow nearshore waters, and on reefs located near river mouths. Habitat: Large populations of this benthic invertebrate are found in the large estuarine bays and sounds of the Gulf (with most concentrations found within 10-meter depths). Sedentary in character, this invertebrate attaches in clusters to shell reefs, firm mud/shell bottoms and other hard substrates. Feeding and Behavior: The American oyster filter-feeds principally on small unicellular algae and incidentally on suspended detrital particles. It is found in association with numerous predators, commensals, and parasites. Reproduction: Spawning also occurs in estuarine habitats. In the Gulf of Mexico, April to October are the most active months, although spawning has been reported during all months except February and March. Nursery areas are found in estuarine waters. Movement: Planktonic larvae drift with the tides and currents until they settle on solid substrate. Fisheries: This species is commercially harvested throughout its range for its meat, the seasonality for harvesting being state regulated. The fishery for this species is the fourth largest in the U.S. Gulf of Mexico and there is also a commercial fishery in Mexican waters. The species is harvested recreationally.

Abstract: oyster reef in the Colorado River delta in the eastern arm of Matagorda Bay, mapped in 2007. In late February 2007, just after a northern that blew through and made the delta shallow, BIO-West had aerials flown of the delta. They digitize the aerials. Then, BIO-West went out in an airboat at high tide in the delta area and coded the oyster formations by percentage density. Melissa F. told me they coded: 0-25%, scattered shell; 25-75%, no specific label; 75-100%, solid reef. They incorporated this oyster reef data into the habitat assessment file for the Matagorda Bay Health Evaluation Project (final report 2008). Now one discrepancy- I'm looking at the table for the shapefile, and under density, I see 25, 50, 75. I'm going to assume 25 means 0-25%, scattered shell; 50 means 25-75%; and 75 means 75-100%, solid reef." Kathleen Welder HRI TAMU-CC Oyster reef distribution in and around the project area, Eastern Arm of Matagorda Bay (EAMB) and East Matagorda Bay (EMB), was previously mapped by Texas Parks and Wildlife (TPWD) and the Texas General Land Office (GLO) using various sources. The MBHE project team conducted a field ground-truthing effort in October 2005 to verify and update the distribution maps.Large areas of previously undocumented oyster reefs were identified in the immediate area of the new Colorado River delta (CRD) during the 2006 field activities.The extent of Eastern oyster (Crassostrea virginica) reefs in shallow waters in the vicinity of the CRD was revealed during an airboat survey of the area in the fall of 2006 and again in February 2007. The density of these reefs varied from scattered individual oyster clumps to solid oyster reef. On March 5, 2007 the Colorado River Delta (CRD) area was flown and aerial photography was taken directly after a cold front had passed (when strong North winds result in extremely low water levels, exposing much of the delta bay bottom). These aerial photographs were geo-rectified and utilized in GIS form to assess the location and density of oyster reef coverage in the region. Areas possessing oyster reef coverage were digitized with ESRI ArcMap software and categorized into one of three densities: 25% coverage of scattered reef, 25-75% coverage of reef and 75% solid reef areas. Examples of these density categories as seen in the field are provided in Figures 3.1, 3.2 and 3.3 of the 2007 MBHE Report. Mapped oyster reef locations and densities were verified on April 11, 2007 utilizing an airboat and a Trimble Pro XRS GPS unit with sub-meter accuracy. The final mapped extent of oyster reef in the CRD comprised 147.1 acres, which amounts to approximately 20% of the mapped oyster reef in East Matagorda Bay (EMB) and 13% of the mapped oyster reef in the Eastern Arm of Matagorda Bay (EAMB) (Figure 3.4). Of this total, 31.4 acres were classified as 25% coverage by oysters, 60.4acres were classified as 25-75% coverage by oysters, and 55.3 acres were classified as 75% coverage by oysters. The oyster coverage mapped in the CRD in 2007 was added to the final physical habitat map to provide a comprehensive map of existing physical habitat within the project area (Figure 3.5). This final habitat map serves as the physical habitat input to the GIS-based habitat model. This map also has the potential to be updated in the future, as potential changes to physical habitat in the project area occur. Purpose: To conduct the Matagorda Bay Health Evaluation habitat assessment, statistical models of oyster reef condition, and spatially referenced habitat models were generated using GIS. Fieldwork was conducted to verify previous oyster mapping from TPWD and GLO in EMB and EAMB. Fieldwork was also conducted to map the unmapped extent of oysters in the Colorado River delta(CRD) region . The new CRD oyster mapping was added to the physical habitat input file for the MBHE habitat model. During fieldwork conducted in spring 2007, data was collected on commercial size oysters and dermo infestation of reefs in the CRD and East Matagorda Bay (EMB), as was information on the use of shallow estuarine habitats by juvenile shellfish and finfish across the Matagorda Bay system.

It is important to understand what factors control oyster distribution to effectively maintain and manage the present oyster reefs and associated habitats. Understanding controls on distribution can also aid in oyster reef protection and restoration efforts.The American or Eastern Oyster (Crassostrea virginica) is the prevalent oyster species along the northern Gulf of Mexico coast, including Copano Bay, Texas. C. virginica has a free-swimming larval stage, lasting 14 to 30 days, after which the larva goes through a settling, or spatting process in which it must permanently attach itself to the bottom (Kennedy, 1996). During the larval stage, the oyster is susceptible to the multitude of estuarine hydrodynamic processes that distribute the larva throughout the estuary. C. virginica is a filter feeder, so it needs to settle and attach to a site which will permanently keep it out of the fine bay bottom mud to avoid suffocation by fine-grained sediment. It also needs to settle within the intertidal to subtidal portion of the bay, to allow it access to tidal flow and nutrients (Kennedy, 1996). Over the course of history in Texas bay systems, the oysters have been able to accumulate and form reefs in areas that are favorable to their success. Copano Bay is an "upper bay" system within the Mission-Aransas-Copano Bay system (Figure 1). Copano Bay has undergone very little modification, it has no dredged navigational channels and in general lacks significant infrastructural modifications found in other bays, such as Galveston, Corpus Christi or Lavaca Bays. As a result, it is an ideal setting to investigate the natural controls on oyster reef distribution. The oyster reefs in Copano Bay appear to consist of longitudinal reefs attached to the shoreline extending perpendicularly into the bay, longitudinal reefs in the middle of the bay oriented parallel to shoreline and patch reefs that are randomly oriented throughout the bay. Surficial sediments contained within Copano Bay consist primarily of unconsolidated muds, sands, and shell gravel. With the lack of obvious controls on the distribution of oyster reefs, such as rock outcrops, the big question is, what does control their distribution? It is our contention that the natural distribution of oyster reefs in Copano Bay are controlled mainly by the antecedent geology found beneath the bay sediment. Oysters will form in areas where there exists shallow, hard substrate ideal for oyster attachment. Studying the underlying geology of oyster reefs could have major implications on understanding their distribution. This study will have significant implications for the future research and resource management in Copano Bay, such as oyster reef protection and restoration. Restored reefs can be placed in areas where known stable underlying geology is present to ensure the reef is successful and the oysters not subside into the soft bay mud and become suffocated by fined grained sediment particles. If large extents of buried oyster reefs are found, this could indicate an enormous decline in oyster reef population over time and actions could be taken to prevent any further decline from happening. Purpose: For the purpose of this study, the substrate type will be considered the most important influence for the initial distribution of oyster reefs. Regardless of other environmental conditions, the substrate must be suitable for initial oyster colonization or the oyster will not survive. Where there are oyster reefs present in the geologic past, there was adequate substrate for initial settlement. Adequate substrate includes any hard, smooth surface such as compacted mud, sand or shell shoals, lose shell or sunken logs. Loose sand or mud can shift and break the oyster free of its anchor, or bury and suffocate it (Kennedy,1996). The ideal substrate for larval oysters has been found to be existing reef or oyster shells (Kilgen and Dugas 1989; Stanley and Sellers 1986; Michener and Kenny 1991; Kennedy, 1996). Some current oyster reefs are most likely built on top of reefs that initially grew thousands of years ago when the incised paleo-river valleys began to fill with sediment (Bouma, 1976). The oyster reefs build up vertically and out horizontally with new oysters growing atop older ones. Ideally, without significant outside physical influences to move them, the present day oyster reefs would exist in the same general locations as where they were initially colonized, only to a larger extent. However, oyster reefs do not only build atop other reefs. If suitable substrate is formed or becomes available elsewhere, larvae will also settle atop it forming a new reef. Therefore each reef in the current oyster reef distribution may have different geologic controls. Supplemental Information: This is the final report of our CMP Cycle 12 project to identify and delineate oyster reefs and other bottom features in Copano Bay. This project was conducted during two successive CMP Cycles, Cycles 11 & 12. During the Cycle 11 we conducted the bulk of the field component of the geophysical mapping. During Cycle 12 will processed the geophysical data and generate maps and prepare the final report and conducted follow up field work, including field verification of the areas identified as reef. This project is a cooperative effort between Department of Oceanography, Texas A&M University(TAMU), Department of Marine Sciences Texas A&M University at Galveston(TAMUG); the Institute for Coastal Studies at Texas A&M University at Corpus Christi(TAMUCC), and the Texas Parks and Wildlife Department (TPWD).

Logical Consistency Report: To test the validity of our oyster reef map we conducted a survey to verify the accuracy of our interpretations. To do this a geo-referenced grid was placed over the mapped area in GIS with a grid area of 4 kilometers squared, or a grid length/width of 2,000 meters. Then points were randomly selected in each grid using GIS for each mapped category, for a total of 155 survey sites. We used a stratified design selecting 50 sites in the Oyster Reef category, 31 on Mud, 20 on Sand, and 10 each on Shell on Mud and Shell on Sand. At each each station physico-chemical data (depth, water temperature, dissolved oxygen, percent saturation, pH, salinity), secchi depth, wind speed and direction, and sea state data were collected. For the oyster dredge collections we employed the data collection procedures employed by the TPWD Coastal Fisheries Division for their oyster population surveys (TPWD, 2002). This includes, in addition to counts of live oysters and dead shell, a count of live spat on five live oysters and five dead shells, plus the lengths of up to 19 live oysters are measured. An initial analysis of the data (UNIVARIATE; SAS, 1990) determined that the count data for live oysters and dead shell was not normally distributed as there was an abundance of zero values. An analysis of variance (ANOVA) was performed on the ranked count data for both live oysters and dead shell. Then a Tukey type multiple comparison was performed on the map classification categories for both the live oyster and dead shell (Zar, 1999). These analyses were performed on both the original validation data and the supplemented validation data with the adjusted map classification categories. Completeness Report: Over 200 survey lines each with a spacing interval of 150 m provided nearly complete coverage of the bay bottom. Survey cover was limited to areas with a minimum of 1.2 m water depth to protect the equipment from damage. Attribute Accuracy Report: Validation of oyster reef maps To test the validity of our oyster reef map we conducted a survey to verify the accuracy of our interpretations.

Then points were randomly selected in each grid using GIS for each mapped category, for a total of 155 survey sites. We used a stratified design selecting 50 sites in the Oyster Reef category, 31 on Mud, 20 on Sand, and 10 each on Shell on Mud andShell on Sand. At each each station physico-chemical data (depth, water temperature, dissolved oxygen, percent saturation, pH, salinity), secchi depth, wind speed and direction, and sea state data were collected. For the oyster dredge collections we employed the data collection procedures employed by the TPWD Coastal Fisheries Division for their oyster population surveys (TPWD, 2002). This includes, in addition to counts of live oysters and dead shell, a count of live spat on five live oysters and five dead shells, plus the lengths of up to 19 live oysters are measured. An initial analysis of the data (UNIVARIATE; SAS, 1990) determined that the count data for live oysters and dead shell was not normally distributed as there was an abundance of zero values. An analysis of variance (ANOVA) was performed on the ranked count data for both live oysters and dead shell. Then a Tukey type multiple comparison was performed on the map classification categories for both the live oyster and dead shell (Zar, 1999). These analyses were performed on both the original validation data and the supplemented validation data with the adjusted map classification categories. ground condition 2007-07 Source Contribution: Copano Bay Oyster Shells on Mud.shapefile Oyster Reef, Copano Bay, Texas, TAMUG, TAMUCC, TPWD, OSU, 2007 (ShellonMud.shp) Copano Bay Oyster Shells on Mud 2010 publication Dellapenna, Dr. Timothy M., Department of Marine Sciences Texas A&M University at Galveston (TAMUG); Erin Weaver, Department of Oceanography Texas A&M University at Galveston (TAMUG); The Institute for Coastal Studies at Texas A&M University at Corpus Christi (TAMUCC); James Simons, Texas Parks and Wildlife Department (TPWD); and Alex Simmons and Taylor Traviani, Oregon State University (OSU) resourceProvider See Oyster reef and seabed mapping of Copano Bay - CMP Cycle 11 Final Report (Copano Bay Final Report.pdf Abstract: Oysters play an important role in maintaining water quality and providing habitat for juvenile fish, such as black drum, toadfish and sheepshead, and other marine organisms including crabs, shrimp, mud worms and mussells in estuaries (Kilgen and Dugas, 1989). It is important to understand what factors control oyster distribution to effectively maintain and manage the present oyster reefs and associated habitats. Understanding controls on distribution can also aid in oyster reef protection and restoration efforts. The American or Eastern Oyster (Crassostrea virginica) is the prevalent oyster species along the northern Gulf of Mexico coast, including Copano Bay, Texas. C. virginica has a free-swimming larval stage, lasting 14 to 30 days, after which the larva goes through a settling, or spatting process in which it must permanently attach itself to the bottom (Kennedy, 1996). During the larval stage, the oyster is susceptible to the multitude of estuarine hydrodynamic processes that distribute the larva throughout the estuary. C. virginica is a filter feeder, so it needs to settle and attach to a site which will permanently keep it out of the fine bay bottom mud to avoid suffocation by fine-grained sediment. It also needs to settle within the intertidal to subtidal portion of the bay, to allow it access to tidal flow and nutrients (Kennedy, 1996). Over the course of history in Texas bay systems, the oysters have been able to accumulate and form reefs in areas that are favorable to their success. Copano Bay is an "upper bay" system within the Mission-Aransas-Copano Bay system (Figure 1). Copano Bay has undergone very little modification, it has no dredged navigational channels and in general lacks significant infrastructural modifications found in other bays, such as Galveston, Corpus Christi or Lavaca Bays. As a result, it is an ideal setting to investigate the natural controls on oyster reef distribution. The oyster reefs in Copano Bay appear to consist of longitudinal reefs attached to the shoreline extending perpendicularly into the bay, longitudinal reefs in the middle of the bay oriented parallel to shoreline and patch reefs that are randomly oriented throughout the bay. Surficial sediments contained within Copano Bay consist primarily of unconsolidated muds, sands, and shell gravel. With the lack of obvious controls on the distribution of oyster reefs, such as rock outcrops, the big question is, what does control their distribution? It is our contention that the natural distribution of oyster reefs in Copano Bay are controlled mainly by the antecedent geology found beneath the bay sediment. Oysters will form in areas where there exists shallow, hard substrate ideal for oyster attachment. Studying the underlying geology of oyster reefs could have major implications on understanding their distribution. This study will have significant implications for the future research and resource management in Copano Bay, such as oyster reef protection and restoration. Restored reefs can be placed in areas where known stable underlying geology is present to ensure the reef is successful and the oysters not subside into the soft bay mud and become suffocated by fined grained sediment particles. If large extents of buried oyster reefs are found, this could indicate an enormous decline in oyster reef population over time and actions could be taken to prevent any further decline from happening. Purpose: For the purpose of this study, the substrate type will be considered the most important influence for the initial distribution of oyster reefs. Regardless of other environmental conditions, the substrate must be suitable for initial oyster colonization or the oyster will not survive. Where there are oyster reefs present in the geologic past, there was adequate substrate for initial settlement. Adequate substrate includes any hard, smooth surface such as compacted mud, sand or shell shoals, lose shell or sunken logs. Loose sand or mud can shift and break the oyster free of its anchor, or bury and suffocate it (Kennedy,1996). The ideal substrate for larval oysters has been found to be existing reef or oyster shells (Kilgen andDugas 1989; Stanley and Sellers 1986; Michener and Kenny 1991; Kennedy, 1996). Some current oyster reefs are most likely built on top of reefs that initially grew thousands of years ago when the incised paleo-river valleys began to fill with sediment (Bouma, 1976). The oyster reefs build up vertically and out horizontally with new oysters growing atop older ones. Ideally, without significant outside physical influences to move them, the present day oyster reefs would exist in the same general locations as where they were initially colonized, only to a larger extent. However, oyster reefs do not only build atop other reefs. If suitable substrate is formed or becomes available elsewhere, larvae will also settle atop it forming a new reef. Therefore each reef in the current oyster reef distribution may have different geologic controls. Supplemental Information: This is the final report of our CMP Cycle 12 project to identify and delineate oyster reefs and other bottom features in Copano Bay. This project was conducted during two successive CMP Cycles, Cycles 11 & 12. During the Cycle 11 we conducted the bulk ofthe field component of the geophysical mapping. During Cycle 12 will processed the geophysical data and generate maps and prepare the final report and conducted followup field work, including field verification of the areas identified as reef. This project is a cooperative effort between Department of Oceanography, Texas A&M University(TAMU), Department of Marine Sciences Texas A&M University at Galveston(TAMUG); the Institute for Coastal Studies at Texas A&M University at Corpus Christi(TAMUCC), and the Texas Parks and Wildlife Department (TPWD).

Completeness Report: Over 200 survey lines each with a spacing interval of 150 m provided nearly complete coverage of the bay bottom. Survey cover was limited to areas with a minimum of 1.2 m water depth to protect the equipment from damage.

Purpose: The oysters data set is a compilation of three data sets. The first data set was developed by Dr. Eric Powell of Texas A&M University's Department of Oceanography under the auspices of the Galveston Bay National Estuary Program. The reefs were mapped using acoustic equipment designed to return echo signal from the bay bottom. In very shallow areas where a smaller boat was used, it was not possible to hang the equipment over the side of the boat; therefore a poling technique was used to determine the location of the oyster reefs. The second and third data sets were both acquired from the Texas Parks and Wildlife Department. One was developed by a team led by Warren Pulich and used aerials circa 1989. The other was developed by Betsi Blair which also used aerial photographs and surveyed submerged aquatic vegetation including oyster reefs. Access: Free to public.
