Internal code | Internally assigned metadata identifier | 2191 |
Title | The title is used to provide a brief and precise description of the dataset such as 'Date', 'Originating organisation/programme', 'Location' and 'Type of survey'. All acronyms and abbreviations should be reproduced in full. | 1966-1975 Cornwall Palinurus elephas fishery survey |
File Identifier | The File Identifier is a code, preferably a GUID, that is globally unique and remains with the same metadata record even if the record is edited or transferred between portals or tools. | 064e716ce6ce2c439f85193d98ba80d2 |
Resource Identifier | This is the code assigned by the data owner. | MRMLN0010000012B |
Resource type | The resource type will likely be a dataset but could also be a series (collection of datasets with a common specification) or a service. | dataset |
Start date | This describes the date the resource starts. This may only be the year if month and day are not known | 1966-01-01 |
End date | This describes the date the resource ends. This may only be the year if month and day are not known | 1975-12-31 |
Spatial resolution | This describes the spatial resolution of the dataset or the spatial limitations of the service. | inapplicable |
Frequency of updates | This describes the frequency with which the resource is modified or updated i.e. a monitoring programme that samples once per year has a frequency that is described as 'annually'. | notPlanned |
Abstract | The abstract provides a clear and brief statement of the content of the resource. | Palinurus elaphas records from study of Palinurus elaphas fishery in Cornwall. The areas had to be estimated as no precise latitude and longitude coordinates were provided. |
Lineage | Lineage includes the background information, history of the sources of data, data quality statements and methods. | Carried out between 1966 to 1975 by means of catch records, catch measurements and tagging experiments. Catch per unit effort by pot fishermen increases from spring to autumn and decreases during the winter; that by divers is fairly steady throughout the year. To allow for possible regional differences the area was divided into 5 subareas. 1966-1975 The fishery for crawfish, Palinurus elephas, off the coast of Cornwall Off the coast of Cornwall from the Lizard Head to Padstow there has been, for many years, a small but locally important fishery for crawfish Palinurus eliphas. The fishermen had used pots and tangle nets up to the outbreak of the Second World War in 1939. From 1945 tangle nets had been little used and the fishery was pursued mainly by pot fishermen until the early 1960s when divers using self-contained underwater breathing apparatus began to collect crawfish. Tangle nets were re-introduced widely in the late 1960s. The divers rapidly increased their landings and the fishermen using pots expressed fears that the divers would overexploit the stocks. A study was undertaken to see if these fears were justified. This study was lead by the Fisheries Experiment Station Conwy, Gwynedd and carried out between 1966 to 1975 by means of catch records, catch measurements and tagging experiments. Catch per unit effort by pot fishermen increases from spring to autumn and decreases during the winter; that by divers is fairly steady throughout the year. To allow for possible regional differences the area was divided into 5 subareas. The areas had to be estimated as no precise latitude and longitude coordinates were provided. Furthermore some of the areas are marked by a single point. |
