Establishing A National Shellfish Sanitation Program In The Gambia, West Africa, Michael A. Rice, Foday Conteh, Karen Kent, Brian Crawford, Banja Bamba, Fatou Janha, Ismaila Bojang
Michael A Rice
A successful national program to assure sanitary quality of molluscan shellfish requires a multi-disciplinary and multi-agency governmental training, data collection, policy development and management effort in collaboration with members of the shellfish industry. The Tanbi Wetlands and other estuaries of Gambia support shellfisheries for oysters, Crassostrea tulipa, and the senile ark, Senelia senilis, conducted by the TRY Oyster Women’s Association. With low shellfish prices and a small local market, a Gambian National Shellfish Sanitation Program (GNSSP) was begun as a means to boost consumer confidence and allow market access to Gambia’s robust seasonal international tourism trade. Gambian officials began training …

The Shellfish Corner -- Vibrios And Shellfish, Michael Rice
Michael A Rice
Pathogenic Vibrios are becoming an increasing problem for shellfish producers in North America and elsewhere. This paper reviews current research into the pathogenic nature of Vibrios and provides some practical advice for avoiding the propagation of Vibrios on shellfish farms nd in wild harvest molluscan shellfish.
Bacterial Community Profiling Of The Eastern Oyster (Crassostrea Virginica): Comparison Of Culture-Dependent And Culture-Independent Outcomes, Kenneth J. La Valley, Steve Jones, Marta Gomez-Chiarri, Joseph Dealteris, Michael A. Rice
Bacterial Community Profiling Of The Eastern Oyster (Crassostrea Virginica): Comparison Of Culture-Dependent And Culture-Independent Outcomes, Kenneth J. La Valley, Steve Jones, Marta Gomez-Chiarri, Joseph Dealteris, Michael A. Rice

Tissue-associated bacterial community profiles generated using a nested polymerase chain reaction–denaturing gradient gel electrophoresis (DGGE) approach and culture-dependent and culture-independent isolation techniques were compared. Oyster samples were collected from 2 harvest areas along the coast of Maine, in the United States. Profiles from both isolation strategies were evaluated using Sorensen’s index of similarity and cluster analysis of gel banding patterns. Cultureindependent profiles were further evaluated using the Shannon diversity index. In general, the culture-dependent strategy resulted in a greater number of bands within a profile. BacterialDGGEprofiles were found to be highly similar within an isolation strategy, with a higher degree …
Propagation Of Adherent Bacteria On The Brittlestar Ophionereis Annulata (Le Conte) After Enrichment Of Seawater With Amino Acids, Michael A. Rice
Propagation Of Adherent Bacteria On The Brittlestar Ophionereis Annulata (Le Conte) After Enrichment Of Seawater With Amino Acids, Michael A. Rice
Michael A Rice
Epidermal surfaces of the ophiouroid Ophionereis annulata (Le Conte) were examined by scanning electron microscopy. Microvilli, which are characteristic of many transport epithelia, are present on the epidermal surfaces. Epidermal surfaces of freshly-collected brittlestars were compared with brittlestars that were maintained in the laboratory for 48 hours in fresh seawater and in seawater enriched with 20uM glycine. Very few bacteria were observed on the surface of the freshly-collected animals or on animals maintained in the laboratory in fresh seawater. The epidermal surfaces of animals maintained in seawater enriched with 20 uM glycine showed extensive mats of coccoid and bacilloid bacteria. …
