Pollution and overfishing have caused devastating declines in Chesapeake Bay blue crabs, and the federal government has been undercutting state efforts to restore the Bay . Coast estimates annual losses due to green crabs to be approximately $22 million. This invasive species could have a very negative impact on the recreational and commercial harvesting of Dungeness crabs, clams, oysters and mussels. In the 19th century, this crab caused severe damage to the Atlantic Coast’s soft-shell clam industry.
The green crabs have already colonized the cove, but the clammers hope they can trap the existing crabs and keep new ones from moving in while the clams make a comeback. All of these efforts are part of a $70, local offensive aimed at combating the green crab .

To investigate potential bioaccumulation of contaminants in shellfish, crab (Cancer magister) muscle was collected from eight sites and littleneck clams (Tapes japonica, Protothaca staminea) from four sites and tested for concentrations of PCBs, other organochlorine compounds including chloropyrifos and pentachlorophenol, cadmium, arsenic, lead, and mercury.
Discharges to Bellingham Bay (WA) have led to high sediment concentrations of mercury and PCBs. The study sampled muscle tissue from crab (Cancer magister) and littleneck clams (Tapes japonica, Protothaca staminea) from the bay to evaluate potential levels of bioaccumulation of these and other contaminants.
The muscle tissue was analyzed for PCBs, other organochlorine compounds, cadmium, arsenic, lead, and mercury. water and aquatic foods (Olowu et al., ). Cubbage, () in his study on bioaccumulation of contaminants in crabs and clams in Bellingham Bay showed that industrial and municipal discharges into the bay have contributed to high sediment concentrations of mercury and PCBs.

Cubbage, () in his study on bioaccumulation of contaminants in crabs and clams in Bellingham Bay showed that industrial and municipal discharges into the bay have contributed to high sediment concentrations of mercury and PCBs. Sediments have been reported to form the major repository of heavy metals in aquatic systems (Adeniyi et al, ).

The geographical co-ordinates of the stations are listed in Table 1. A total of 27 crab samples were collected from three sampling stations over a three-month period (January. Dungeness crabs were again tested in and no heavy metals or PCBs were detectable. The EPA has no follow-up tests scheduled for as no contaminants were detectable.
It is still not recommended to eat mussels, clams or any other filter feeders from Bellingham Bay. This paper reports on the bioaccumulation and distribution of mercury by the hard clam, and discusses its suitability as an indicator organism for metal pollution.
Although clams can obtain mercury both from water and from food, uptake from seawater only was considered here. TZONG-SHEAN CHIN and HON-CHENG CHEN MATERIALS AND METHODS Hard clams, Meretrix lusoria, were obtained from a commercial shellfish farm. Tips for using this map.

Shellfish harvesters have an assortment of opportunities in Washington. Dungeness crab, shrimp, clams, and oysters are all available in the Puget Sound, while razor clams provide a popular digging opportunity along the coast.
For bivalve season information, please see the Puget Sound clam, mussel, and oyster season guide. Past bioaccumulation information indicates that mer- cury contamination in species collected from Bellingham Bay is elevated above reference area levels and is widely distributed throughout the bay.
Significant sediment toxicity was found at several stations, and decreases in the numbers of benthic organisms were noted at numerous stations.

Bellingham Bay is open for many types of fishing except for Salmon during certain times. The more pollution a property produces, the more the property owner pays. But right now these important solutions for reducing pollution and helping blue crabs recover are at risk in the Maryland State Senate.
Lawmakers may eliminate the very programs designed to keep polluted runoff out of the waters where blue crabs live. The California Department of Public Health recently advised people to avoid consumption of certain species of crabs because of potential toxicity. Razor clam.
ELISA indicated that clams in Gomso Bay spawned when the gonad accounted for 20% of the total tissue weight. The fecundity estimated from individual clams before spawning ranged from .Blue Crabs in the Gulf.
Aside from their ecological importance, blue crabs are one of the most economically important fisheries of the Gulf. Louisiana alone lands approximately 26 percent of the total blue crabs for the nation, a value of more than $ million at today’s market prices.Bellingham Bay Sources, transport and impacts of sediment and persistent and emerging contaminants Source and fate Transport dynamics Bioaccumulation pathways.
