Description

Being produced in the mudflats of the Ria de Aveiro lagoon. The Portuguese oyster, Crassostrea angulata, was replaced by its Pacific congener during the last half of the 20th century because of its vulnerability to viruses and parasites and reduced growth. In Portugal, pure populations (i.e. non-hybrid) of C. angulata can only be found in the Sado estuary.

Description

The American Oyster, Crassostrea virginica (Gmelin, 1791) is an important species in bays, estuaries and coastal waters in Texas.

One easy way to identify this species is the dark purple muscle scar in the interior of the valve, in the shape of a comma.

The specimen shown here was found at Copano Bay, Texas. It was featured in a poster on Texas estuarine mollusks I made with Paul Montagna:
https://www.researchgate.net/profile/Fabio_Moretzsohn/publication/253327815_Estuarine_molluscs_of_Texas/links/0046351f7f5eaba72c000000?ev=pub_int_doc_dl&origin=publication_list&inViewer=true

Oyster reefs provide home and shelter for a number of coastal and estuarine species, including fishes and invertebrates. Oyster reef restoration is an important activity that will likely be part of many of the restoration projects starting soon in response to the Deepwater Horizon Oil Spill (2010).

Read more about this species in Tunnell et al (2010)’s Encyclopedia of Texas Seashells, page 321, and in the Texas Seashells, A Field Guide (Tunnell, Barrera and Moretzsohn, 2014), on page 169.

Description

I observed many live specimens of the Eastern Oyster, Crassostrea virginica, during a research cruise by a team of Texas A&M University-Corpus Christi to monitor oyster health. The oysters where collected with a small dredge (as seen in some photos), and a few specimens from each station were brought to the lab for several measurements and test, including the Gonadosomatic Index. Also, several environmental parameters such as water temperature, salinity, etc., were measured.

Also observed among the oysters were some Santo Domingo mussels, Brachidontes domingensis (see other entry), as seen on one photo, and the tiny ecotoparasite gastropod, Boonea impressa.

Read more about this species in Tunnell et al (2010)’s Encyclopedia of Texas Seashells, page 321, and in the Texas Seashells, A Field Guide (Tunnell, Barrera and Moretzsohn, 2014), on page 169.

Description

Copano Bay has several oyster reefs, and several of the beaches around the bay have lots of shells, most of them of Eastern Oyster, Crassostrea virginica. There are shells of many other species on the beach at this location, but typically the oysters are more numerous and have the largest shells.

I did not observe live oysters at this location, but I did see several nearby during a research cruise to Copano Bay on a different date.

Read more about this species in Tunnell et al (2010)’s Encyclopedia of Texas Seashells, page 321, and in the upcoming Texas Seashells, A Field Guide, on page 169.

Here is a Crassostrea gigas or Pacific Oyster, about 4” across, found living on the side of the dock at the marina. A Short Plumose Anemone was nestled on top.
