Seasearch Crawfish, Palinurus elephas, Surveys
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.
Whole of Britain and Ireland.
To gather information regarding the numbers and distribution of Crawfish throughout Britain and Ireland.
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.
Data has been obtained from visual observations by divers.
