The Science\u003Cbr \/\u003E\nEvidence, Data and Digital portfolio of the Marine Directorate (formerly Marine\u003Cbr \/\u003E\nScotland Science (MSS)) is responsible for the biological and ecological goals of the\u003Cbr \/\u003E\ntrial. These goals are to: gather local level information on razor clam populations and\u003Cbr \/\u003E\nstocks, including accurate data gathered by trial participants to supplement stock\u003Cbr \/\u003E\nsurvey work; provide advice on sustainable harvesting levels; and investigate the\u003Cbr \/\u003E\nimpacts of the electrofishing method on target and non-target species.\u003Cbr \/\u003E\nData collected under the trial includes 5896 live razor clams which were dissected\u003Cbr \/\u003E\nand analysed to determine sex, spawning activity, and length-weight relationships.\u003Cbr \/\u003E\nHistological examination of 1468 razor clams revealed evidence of spawning in April\u003Cbr \/\u003E\nand May. Stopping fishing activity during these two months could allow for\u003Cbr \/\u003E\nundisturbed razor clam spawning. Very few undersized (less than 100 mm) razor\u003Cbr \/\u003E\nclams were sampled during this trial, so no results are reported for the suitability of\u003Cbr \/\u003E\nthe Minimum Landing Size (MLS) of razor clams.\u003Cbr \/\u003E\nFishers and processors submitted self-sample data sheets (razor clam length\u003Cbr \/\u003E\nmeasurements) which allowed stock assessments to be conducted for razor clams in\u003Cbr \/\u003E\nthe Firth of Forth and Firth of Clyde trial areas. Assessment results indicated that\u003Cbr \/\u003E\nrazor clams were fished sustainably, with fishing mortality estimated to be below\u003Cbr \/\u003E\nFMSY (the fishing mortality associated with maximum sustainable yield). To enable\u003Cbr \/\u003E\nregular stock assessments in future, continued data collection is necessary.\u003Cbr \/\u003E\nMandatory options could be explored for any future fishery as it is unlikely that data\u003Cbr \/\u003E\nfrom voluntary sampling would be sufficient.\u003Cbr \/\u003E\nRemote Electronic Monitoring (REM) systems on board participating vessels were\u003Cbr \/\u003E\nprimarily used to monitor compliance with the regulations of the trial, but the\u003Cbr \/\u003E\nassociated spatial fishery information informed the design of fishery independent\u003Cbr \/\u003E\nsurveys and allowed mapping of fishing activity. The mapping informed a survey of\u003Cbr \/\u003E\nrazor clams in the Firth of Forth (conducted by the Scottish Association for Marine\u003Cbr \/\u003E\nScience (SAMS)) and enabled stock abundance to be estimated. For the Firth of\u003Cbr \/\u003E\nForth trial area, the harvest rate was calculated by comparing fishery removals to\u003Cbr \/\u003E\nsurvey abundance, and was estimated to be 5.7% for razor clams over the MLS of\u003Cbr \/\u003E\n100 mm.\u003Cbr \/\u003E\nThis trial is an example of collaboration between fishers and scientists, policy\u003Cbr \/\u003E\nmakers, compliance officers, and other agencies involved in this work. Regular\u003Cbr \/\u003E\ncommunication between all parties ensured work progressed and that trial objectives\u003Cbr \/\u003E\ncontinue to be on track for completion by January 2025. However, the trial would\u003Cbr \/\u003E\nhave benefitted from greater engagement between scientists and stakeholders at the\u003Cbr \/\u003E\nstart, so that fishers fully understood the importance of data collection and that\u003Cbr \/\u003E\nappropriate scientific resources and staff were available at each stage of the trial.\u003Cbr \/\u003E\nThis trial commenced with clear limits on the number of vessels (controlled by\u003Cbr \/\u003E\nderogation), defined fishing areas (monitored by REM), daily catch limits and effort\u003Cbr \/\u003E\nrestrictions (maximum number of days fished). Any future management plans should\u003Cbr \/\u003E\nkeep limits under review, alongside regular stock assessments. Stock assessments\u003Cbr \/\u003E\ncould be conducted for other trial areas if sufficient data are available in future.\u003Cbr \/\u003E\nOptions for reference points should be considered alongside regular stock\u003Cbr \/\u003E\nassessments as part of a fisheries management plan, but key to the success of any\u003Cbr \/\u003E\nfuture razor clam fishery is the continued engagement between the fishers,\u003Cbr \/\u003E\nprocessors and all agencies involved in this trial.\u003C\/p\u003E\n","url":"https:\/\/data.marine.gov.scot\/dataset\/progress-biological-and-ecological-goals-scottish-scientific-electrofishery-razor-clams","state":"Active","private":true,"revision_timestamp":"Thu, 09\/12\/2024 - 13:37","metadata_created":"Thu, 09\/12\/2024 - 11:15","metadata_modified":"Thu, 09\/12\/2024 - 13:37","creator_user_id":"ef1d5231-9817-4ea3-875e-aadc55addee0","type":"Dataset","resources":[{"id":"7f8c028b-9cb9-4de3-8d21-c8112c28208b","revision_id":"","url":"https:\/\/www.gov.scot\/publications\/progress-biological-ecological-goals-scottish-scientific-electrofishery-razor-clams-trial\/","description":"\u003Cp\u003EAccess the full report on the Scottish Government website\u003C\/p\u003E\n","format":"html","state":"Active","revision_timestamp":"Thu, 09\/12\/2024 - 11:16","name":"Report: Scottish scientific electrofishery for razor clams trial - biological and ecological goals: progress report","mimetype":"html","size":"","created":"Thu, 09\/12\/2024 - 11:16","resource_group_id":"101d17a8-ed4c-47dc-baec-0d48b9c425e5","last_modified":"Date changed  Thu, 09\/12\/2024 - 11:16"},{"id":"de5a05dc-ed53-428d-9ae5-2c555417913a","revision_id":"","url":"https:\/\/scotland.shinyapps.io\/sg-razor-clam-trial\/","description":"\u003Cp\u003EShiny application that allows you to view and filter data\u003C\/p\u003E\n","format":"html","state":"Active","revision_timestamp":"Thu, 09\/12\/2024 - 13:37","name":"Razor Clam Electrofishing Trial App","mimetype":"html","size":"","created":"Thu, 09\/12\/2024 - 13:37","resource_group_id":"101d17a8-ed4c-47dc-baec-0d48b9c425e5","last_modified":"Date changed  Thu, 09\/12\/2024 - 13:37"}],"tags":[{"id":"c0c074e2-ff1c-4a12-bcf3-d30245c7b6f6","vocabulary_id":"2","name":"fishing effort"},{"id":"fb9ec7a6-0c09-4e34-8571-3890251dced4","vocabulary_id":"2","name":"shellfish reproduction"},{"id":"a6fdf7e2-3aa5-47db-a496-c4da2e63dc61","vocabulary_id":"2","name":"Fisheries and aquaculture"}],"groups":[{"description":"\u003Cp\u003EMarine Directorate manages quota for fish stocks and all inshore fisheries within the 12 nautical mile territorial water limit.
