Metadata: Skomer Marine Conservation Zone ( MCZ ) - Monitoring of King Scallop Pecten maximus
Abstract:
In 2015 Skomer Marine Nature Reserve changed designation to Skomer Marine Conservation Zone (MCZ). Skomer Marine Nature Reserve (MNR) was designated in 1990. The scallop population in the Reserve is of conservation value because of its small size and its remoteness from any substantial population. Scallops were collected commercially and recreationally in the area of the Reserve until 1990. In 1990 the South Wales Sea Fisheries Committee (SWSFC) introduced a byelaw prohibiting scallop collecting by any means. The population of scallops needs to be monitored in order to assess the effectiveness of this byelaw. Surveys have been carried out since 1979 looking at scallop density and size. The purpose of this data capture was to estimate the density of scallops within suitable habitats in the Reserve and to assess the age structure in the population.

| Internal code | Internally assigned metadata identifier | 8545 |
| 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. | Skomer Marine Conservation Zone ( MCZ ) - Monitoring of King Scallop Pecten maximus |
| Alternative title | The purpose of alternative title is to record any additional names by which the dataset may be known. | Skomer Marine Conservation Zone ( MCZ ) formally a Marine Nature Reserve ( MNR ) - Monitoring of King Scallop Pecten maximus, King Scallop moitoring surveys Pecten maximus |
| 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. | NRW_DS101806 |
| Resource Identifier | This is the code assigned by the data owner. | 4f4c4942-4343-5764-6473-313031383036 |
| 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 | 1979-01-01 |
| 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'. | annually |

| Lineage | Lineage includes the background information, history of the sources of data, data quality statements and methods. | The 1979-82 and 1985 surveys used slightly different methods. In 2000 a standard method was developed suitable for volunteer diving teams and which could be repeated in subsequent surveys. Scallops are collected by divers from a two metre band, one metre either side of 50m transects (100m2). The scallops are brought to the surface, their growth rings measured, shells marked with notches for identification and then returned to the site. This is repeated for several transects over several sites of suitable habitat. Survey data is published annually. Most recent: NRW Evidence report No.196 - Skomer MVZ Scallop Survey 2016. |
