Likelihood of Presence of Soft Shelled Clams in the Bay of Fundy and Port Hawkesbury Area Response Plan. The Coastal Oceanography and Ecosystem Research section (DFO Science) reviewed reported Clam harvest and study areas as well utilized local knowledge of the areas to estimate clam flats. A version of this dataset was created for the National Environmental Emergency Center (NEEC) following their data model and is available for download in the Resources section. Cite this data as: Lazin, G., Hamer, A.,Corrigan, S., Bower, B., and Harvey, C. Data of: Likelihood of presence of Soft Shelled Clam in Area Response Planning pilot areas.

The dataset represents known concentration areas of harvested or unharvested Softshell clam (Mya arenaria) in the intertidal zone of the Estuary and the Gulf of St. Lawrence, Quebec region. The dataset was created for the National environmental emergencies centre (NEEC) for preparation and response in case of an oil spill. Concentration areas were defined using Fisheries and Oceans Canada (DFO) inventories conducted between 2000 and 2020. This layer is dependent on the inventories carried out and thus only represents known clam areas.

Biological samples of Geoduck Clams have been collected during surveys in British Columbia as part of the broader survey objectives of determining Geoduck density, distribution and population structure. Samples of Geoducks were collected from 41 locations throughout British Columbia between 1993 and 2002. Clams were measured for total weight, shell length, shell weight and were aged. Biological parameters are presented here for individual clams sampled.

The European Green crab is a pan-global invasive exotic species. Its detrimental effects are well documented, including effects on eelgrass and soft-shelled clams and have defined the species of crab as an 'ecosystem engineer'. A population control program was initiated in 2009 whereby modified shrimp traps are used to remove as many green crabs from Kejimkujik's estuaries as possible. These management efforts are evaluated through standardized monitoring whereby 14 traps are deployed for the same period of time in the same place annually.

Shellfish monitoring has been accepted by the Pacific Bioregion of Parks Canada as a measure of ecosystem health in soft substrates in the intertidal zone. Surveys are used to capture the status of selected bivalves within the national park reserve to determine long-term population numbers and trends in response to natural and/or human disturbance. Shellfish surveys are completed annually in May at selected sites in the Broken Group Islands Unit of Pacific Rim National Park Reserve. Clam and oyster datasets are presented separately, as surveys follow different field protocols, but both use variations of a method of randomly selected quadrat sampling along a transect.

Distribution of clam beds in coastal Beds in British Columbia showing relative abundance (RA) and aboriginal, biological, commercial and recreational relative importance (RI) and overall RI. RI is based on project region and not on the province as a whole. and productivity. Other attributes include season dates, productivity and species.

This data set provides pesticide sample analyses results for finfish (brook and rainbow trout) and shellfish (mussels and soft shell clams) for the province’s Pesticide Monitoring Program. The sampling includes a total of nine rivers that are tested across PEI, with three of the rivers being sampled each year. Finfish are collected from the river by electrofishing or rod and reel. Shellfish are collected from the same river systems manually, as close to the finfish sampling as possible.

The dataset represents known concentration areas of harvested or unharvested Atlantic razor clam (Ensis leei) in the Estuary and the Gulf of St. Lawrence, Quebec Region. It was created for the National Environmental Emergencies Centre (NEEC) for preparation and response purposes in case of an oil spill. Concentration areas were defined using data from Fisheries and Oceans Canada (DFO) inventories, various DFO research projects and commercial fisheries data. This layer is dependent on the inventories carried out and thus only represents the known areas of the Atlantic razor clam.
