A total of 11256 scallops were caught (6276 port side and 4989 starboard) and were all measured, aged and assessed for shell damage. \r\nSizes ranging from 2.0 to 17.0 cm. King scallops were aged between 1 and 10 years (note that age ten is a plus group as it is difficult to identify annual age rings in scallops older than age ten) with the highest numbers of scallops aged five and six.\r\nAll scallops were assessed for damages. Approximately 93% of the scallops caught had a damage index of two (Veale et al., 2001); meaning the edge of the shell was chipped but that the scallop is highly likely to survive. The remainder were assessed as damage level three or four, meaning that the hinge was broken or the scallop was crushed or dead. In addition to king scallops , 861 other individual by-catch (excluding starfish) were identified, measured and assessed for damage. The most numerous by-catch species were brown crab (182 individuals), cuckoo ray (153 individuals) and plaice (129 individuals). A total of 1761 starfish were also identified to species level and assessed for damage with the common starfish (638 individuals), seven armed starfish (288 individuals) and sand star (286 individuals) the most commonly caught. \r\n\r\nForty scallops from five ICES statistical squares were collected and frozen for heavy metal and organic contaminants testing. Results will be used to assess scallop tissues and can potentially be used to improve the spatial coverage of regional status and trends of contaminants in biota as part of the UK annual monitoring programme.\r\n\r\nMarine litter was recorded and retained at every station. This is done routinely as part of monitoring for the UK Marine Strategy (UKMS). On this survey 55 items of litter were recorded and retained from 38 stations, with plastics and fishing items being most common.\r\n\r\nA request was received for staff to record any deformed king scallops during the survey. None were recovered on this survey. Scientists will continue to take note in future surveys.", "includedInDataCatalog": { "@id": "http://portal.medin.org.uk/portal/json-ld/catalog.jsonld" }, "conditionsOfAccess": [ "otherRestrictions: no limitations to public access" ], "temporalCoverage": "2025-07-12/2025-08-01", "keywords": [ { "@type": "DefinedTerm", "identifier": "http://vocab.ndg.nerc.ac.uk/term/N010/4/NDGO0001", "name": "Marine Environmental Data and Information Network" }, { "@type": "DefinedTerm", "name": "Fish and shellfish catch statistics" }, { "@type": "DefinedTerm", "name": "Commercial fish and shellfish populations are healthy" } ], "spatialCoverage": { "@type": "Place", "geo": { "@type": "GeoShape", "box": "56 -4 59 0" }, "additionalProperty": [ { "@type": "PropertyValue", "propertyID": "http://www.opengis.net/def/crs/OGC/1.3/CRS84", "value": "urn:ogc:def:crs:EPSG:4326" } ] }, "maintainer": [ { "@type": "Organization", "name": "Scottish Government (Marine Scotland)", "description": "custodian", "email": "marinescotland@gov.scot", "telephone": "+44 (0)300 244 4000", "address": { "@type": "PostalAddress", "streetAddress": "Mailpoint 11, Area 1B South, Victoria Quay", "postalCode": "EH6 6QQ", "addressLocality": "Edinburgh", "addressCountry": "United Kingdom" } } ], "producer": [ { "@type": "Organization", "name": "Directorate for marine Scotland", "description": "originator", "email": "peter.gibson@gov.scot", "address": { "@type": "PostalAddress" } } ], "publisher": [ { "@type": "Organization", "name": "Scottish Government (Marine Scotland)", "description": "pointOfContact", "email": "marinescotland@gov.scot", "telephone": "+44 (0)300 244 4000", "address": { "@type": "PostalAddress" } } ], "provider": [ { "@type": "Organization", "name": "Scottish Government (Marine Scotland)", "description": "distributor", "email": "marinescotland@gov.scot", "telephone": "+44 (0)300 244 4000", "address": { "@type": "PostalAddress", "streetAddress": "Mailpoint 11, Area 1B South, Victoria Quay", "postalCode": "EH6 6QQ", "addressLocality": "Edinburgh", "addressCountry": "United Kingdom" } } ], "creator": [ { "@type": "Organization", "name": "Directorate for marine Scotland", "description": "originator", "email": "peter.gibson@gov.scot", "address": { "@type": "PostalAddress" } } ], "sdPublisher": { "@type": "Organization", "url": "https://portal.medin.org.uk/portal/", "name": "Marine Environmental Data and Information Network (MEDIN)", "description": "The MEDIN portal contains information about 19493 marine datasets from over 600 UK organisations.
