The results can be summarised as follows: \u2022 For Nephrops, increasing the mesh size and removing the lifting bag improves the selective performance of the gear and the analysis suggests that the codends can be ranked from least to most selective as follows; 80 mmL, 100 mmL, 80 mm and 100 mm. We are not able to show this in a statistical sense as the side of the twin trawl on which the test codend was fished influenced the number of Nephrops caught and as a result the subsequent analysis was unable to calculate 95% confidence bands. \u2022 For whiting (Merlangius merlangus), selectivity improves with increasing mesh size and removal of the lifting bag. There was no side effect. \u2022 For haddock (Melanogrammus aeglefinus) only the presence\/absence of a lifting bag proved significant. There was no influence of mesh size, which is probably due to the small sizes of haddock caught, and there was no side effect.\u003C\/p\u003E\n","url":"https:\/\/data.marine.gov.scot\/dataset\/effects-lifting-bag-nephrops-selectivity","state":"Active","log_message":"Update to resource \u0027Property title\u0027","private":true,"revision_timestamp":"Tue, 01\/07\/2020 - 18:22","metadata_created":"Mon, 03\/13\/2017 - 12:32","metadata_modified":"Tue, 01\/07\/2020 - 18:22","creator_user_id":"218af04f-a391-4ecf-ad98-c91fd32c2b17","type":"Dataset","resources":[{"id":"7e3204cc-f87c-42d2-b5e6-aa846dd0c311","revision_id":"","url":"https:\/\/data.marine.gov.scot\/sites\/default\/files\/\/SMFS0802.pdf","description":"\u003Cp\u003EPDF report\u003C\/p\u003E\n","format":"pdf","state":"Active","revision_timestamp":"Tue, 01\/07\/2020 - 14:53","name":"Scottish Marine and Freshwater Science Vol 8 No 2 - report","mimetype":"application\/pdf","size":"722.36 KB","created":"Mon, 03\/13\/2017 - 12:33","resource_group_id":"d0fc86dc-1394-43d4-aef1-c8cf5ac500f9","last_modified":"Date changed  Tue, 01\/07\/2020 - 14:53"},{"id":"70271eab-5be2-46ee-8b15-d523c95febd4","revision_id":"","url":"https:\/\/data.marine.gov.scot\/sites\/default\/files\/\/SMFS_0802_Figure1%2B2_0.csv","description":"\u003Cp\u003EDescribes Nephrops catch rates for port and staboard side combinations of mesh sizes and lift bags.
