Report On Sanitary Shoreline Survey Within The Tanbi Wetlands National Park And Other Shellfish Harvesting Communities, The Gambia May 2012

Report On Sanitary Shoreline Survey Within The Tanbi Wetlands National Park And Other Shellfish Harvesting Communities, The Gambia

Michael A Rice

Emphasis is placed on the sanitary control of shellfish because of the direct relationship between pollution of shellfish growing areas and the transmission of diseases to humans. Shellfish borne infectious diseases are generally transmitted via a fecal - oral route. To accurately assess waters for shellfish harvesting, an evaluation of the pollution sources that are likely to affect the area is required by the NSSP. The shoreline survey is conducted of the shellfish growing area shoreline and estuary to locate pollution sources that could have an effect on the water quality of the area. The shoreline survey team visited 15 …

Results Of A Preliminary Shoreline Shellfish Sanitary Survey Near Banjul, Gambia Conducted On 18 June 2011, Kanyi Babanding, Michael A. Rice

Michael A Rice

A preliminary shoreline survey was conducted along the Bund Road (frequently referred to as Bond Road) levee and the Banjul-Serrekunda Highway in the northern Tanbi Wetlands oyster harvesting area in the metropolitan Banjul area. In part this was designed as a training exercise for Gambian officials will be assuming responsibility for future shoreline surveys in the Gambia. Key identified areas of concern include the Banjul fish landing area on Bund Road utilized by a number of artisanal fishers; an over-water toilet facility for fishers near the fish landing site; evidence of illegal waste and rubbish dumping along Bund Road; an …


A Review Of Shellfish Restoration And Management Projects In Rhode Island, Michael A. Rice, April Valliere, Angela Caporelli May 2000

A Review Of Shellfish Restoration And Management Projects In Rhode Island, Michael A. Rice, April Valliere, Angela Caporelli

Michael A Rice

Shellfish management and restoration efforts in Rhode Island date back to the 19th century. From the late 1890s to the Second World War the Rhode Island Fisheries Commission operated a lobster hatchery in Wickford Harbor in response to a perceived decline in lobster catches in Narragansett Bay. Berried lobsters were collected, eggs hatched, larvae reared, and postlarval fifth stage juveniles were released into the bay. The project was discontinued primarily because of costs and a failure to demonstrate the efficacy of juvenile seeding in improving lobster catches. From the 1930s to the 1980s, there have been several similar efforts to …

Effects Of Intensive Fishing Effort On The Population Structure Of Quahogs, Mercenaria Mercenaria (Linnaeus, 1758), In Narragansett Bay, Michael Rice, Charles Hickox, Itrat Zehra

Michael A Rice

Mercenaria mercenaria and sediment samples were collected from 3 locations in Narragansett Bay: Greenwich Cove, Greenwich Bay, and the West Passage. Greenwich Cove has been closed to shellfishing for several decades. Average density of quahogs in the cove was 190/m super(2), ranging from 32 m super(2)-500/m super(2) in 30 quadrats. Average valve length of quahogs in Greenwich Cove was 62 mm. Average density in Greenwich Bay was 78/m super(2), ranging from 8/m super(2)-184/m super(2). Average valve length was 31 mm. There was a slightly higher content of very fine-grained sands, silts, and clays in the Greenwich Cove sediments. Average Mercenaria) …
