Access data
Availability: Restricted
The data are withheld from general circulation and disclosure but access may be obtained on a case-by-case basis through negotiation

Notes:

Access to crawfish data in Wales has been restricted at the request of the Countryside Council for Wales. Elsewhere full access is given. The reason for the restriction is because in the view of CCW crawfish are vulnerable to human disturbance and thus full disclosure to the public (especially of positions) could lead to environmental harm. This sensitive information may be made available under licence to specific organisations and individuals that need to know to avoid harm to the environment.


Description
This survey was carried out to gather information regarding the numbers and distribution of Crawfish throughout Britain and Ireland. The dataset consists of records of sightings of Palinurus elephas by scuba divers. more

This dataset consists of records of sightings of Palinurus elephas or Crawfish by scuba divers. The welsh records from 1969 - 2009 were obtained from logbook entries made by divers. Data from 2009 onwards is from entries made by divers on the Seasearch online Crawfish observation site. It should be noted that other observations of crawfish made during wider Seasearch surveys are included in the Seasearch Marine Surveys database and are not duplicated here. Data has been provided by volunteer divers and does not attempt to provide a comprehensive picture of distribution of crawfish either spatially or temporarily. There can be high confidence in the accuracy of the records made as crawfish is an easily identified species, however, absence of records will in part be due to sporadic nature of recording. Further information available from the Seasearch Coordinator (Chris Wood).
