Abstract:
1985 Gulf of Mexico Atlas abstract American oyster Crassostrea virginica Ostión americano Description Range:
The American oyster, a bivalve mollusc of the family Ostreidae, is found in the western Atlantic from the
Gulf of St. Lawrence to the Yucatan Peninsula. 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.
Purpose:
To display American oyster (Crassostrea virginica Ostión americano) habitats in the 2011 Gulf of Mexico
Digital Atlas.

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
TexasGeneral Land Office (GLO) using various sources. The MBHE project team conducted a
fieldground-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 ofthe 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. (Data was available for EAMB from another monitoring program).

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.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 Bayappear 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
ofunconsolidated muds, sands, and shell gravel. With the lack of obvious controls on the

substrate type will be considered the most important influencefor the initial distribution of
oyster reefs. Regardless of other environmental conditions, the substratemust be suitable for
initial oyster colonization or the oyster will not survive. Where there are oyster reefspresent
in the geologic past, there was adequate substrate for initial settlement. Adequate
substrateincludes 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 oysterreefs are most likely built on top of reefs that
initially grew thousands of years ago when the incisedpaleo-river valleys began to fill with
sediment (Bouma, 1976). The oyster reefs build up vertically andout horizontally with new
oysters growing atop older ones. Ideally, without significant outside physicalinfluences to move
them, the present day oyster reefs would exist in the same general locations as wherethey were
initially colonized, only to a larger extent. However, oyster reefs do not only build atop
otherreefs. If suitable substrate is formed or becomes available elsewhere, larvae will also
settle atop itforming a new reef. Therefore each reef in the current oyster reef distribution
may have differentgeologic controls. Supplemental Information: This is the final report of our
CMP Cycle 12 project to identify and delineate oyster reefsand other bottom features in Copano
Bay. This project was conducted during twosuccessive CMP Cycles, Cycles 11 & 12. During the

the accuracy of ourinterpretations. 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, percentsaturation, pH,
salinity), secchi depth, wind speed and direction, and sea state data were collected. For
theoyster dredge collections we employed the data collection procedures employed by the TPWD
CoastalFisheries Division for their oyster population surveys (TPWD, 2002). This includes, in
addition to countsof live oysters and dead shell, a count of live spat on five live oysters and
five dead shells, plus the lengthsof up to 19 live oysters are measured.An initial analysis of
the data (UNIVARIATE; SAS, 1990) determined that the count data for liveoysters and dead shell
was not normally distributed as there was an abundance of zero values. Ananalysis of variance
(ANOVA) was performed on the ranked count data for both live oysters and deadshell. Then a Tukey
type multiple comparison was performed on the map classification categories forboth the live
oyster and dead shell (Zar, 1999). These analyses were performed on both the originalvalidation
data and the supplemented validation data with the adjusted map classification categories.

See Oyster reef and seabed mapping of Copano Bay - CMP Cycle 11 Final Report (Copano Bay Final
Report.pdfAbstract: 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

(Texas Coastal Coordination Council (CCC) rock outcrops and serpulid worm reefs have been
removed)] Includes Oyster Reefs (shell and live reefs) Galveston Bay, Texas, GLO, 2004 Abstract:
To address the issues of concern, and in response to the requirements of the Coastal
Coordination Act, the Coastal Coordination Council has designated Oyster Reefs as a coastal
natural resource area requiring special management under the Coastal Management Program and
defined as Natural or artificial formations in intertidal or subtidal areas that are composed of
oyster shell, live oysters, and other organisms and that are discrete contiguous, and clearly
distinguishable from scattered oysters. Oyster reefs not only support the oyster fishery but
also serve as habitat, forage ground, or hiding places for numerous estuarine species. Purpose:
The oysters data set is a compilation of three data sets. The firs 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.

Old link no longer available http://www.glo.state.tx.us/gisdata/gisdata.html Abstract: To address
the issues of concern, and in response to the requirements of the Coastal Coordination Act, the
Coastal Coordination Council has designated Oyster Reefs as a coastal natural resource area
requiring special management under the Coastal Management Program and defined as Natural or
artificial formations in intertidal or subtidal areas that are composed of oyster shell, live
oysters, and other organisms and that are discrete contiguous, and clearly distinguishable from
scattered oysters. Oyster reefs not only support the oyster fishery but also serve as habitat,
forage ground, or hiding places for numerous estuarine species. Purpose: For mapping at a scale
of 1:24000 or smaller. Access: Free to public.
