Metadata: CodSELect - using light to improve cod selectivity in North sea Nephrops trawl gears - Behavioural aquarium tank trials
Abstract:
This dataset contains all the laboratory tank trial data from the CodSELect project which aims to support North Sea Nephrops fishers with a new technical measure to reduce the capture of cod and maintain catch of their target species, which would allow improvements in sustainable catching, reduce discards and ultimately lead to a healthier, more sustainable UK fishing and seafood sector. There are seven datasets in total, 6 for cod and one for saithe measuring behavioural responses to a range of different artificial light parameters including blue, green, red and white constant light or strobing light with a frequency of 1 Hz at 5 or 50%. The distance of the fish from the light at set timepoints throughout the trial was used as the unit of measure and the light was generated using LED light pods and a coiled 20m length of fibre optic cable. All laboratory tank trials were carried out in the Marine Directorates aquarium facilities in Aberdeen.

| 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. | CodSELect - using light to improve cod selectivity in North sea Nephrops trawl gears - Behavioural aquarium tank trials |
| 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. | Marine_Scotland_FishDAC_12491 |
| Resource Identifier | This is the code assigned by the data owner. | Marine_Scotland_FishDAC_12491 |
| 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 | 2022-11-16 |
| End date | This describes the date the resource ends. This may only be the year if month and day are not known | 2024-03-31 |
| Spatial resolution | This describes the spatial resolution of the dataset or the spatial limitations of the service. | 200.00 |
| Spatial resolution unit | This describes the unit of spatial resolution which for distance must be metres. | http://standards.iso.org/ittf/PubliclyAvailableStandards/ISO_19139_Schemas/resources/uom/gmxUom.xml#m |
| 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'. | Not Planned |
| Abstract | The abstract provides a clear and brief statement of the content of the resource. | This dataset contains all the laboratory tank trial data from the CodSELect project which aims to support North Sea Nephrops fishers with a new technical measure to reduce the capture of cod and maintain catch of their target species, which would allow improvements in sustainable catching, reduce discards and ultimately lead to a healthier, more sustainable UK fishing and seafood sector.

| Lineage | Lineage includes the background information, history of the sources of data, data quality statements and methods. | CodSELect originated from previously observed behaviour of cod in a laboratory tank trial, completed by Marine Directorate (MD) as part of the Scottish Government, where cod showed a negative phototactic response to blue and green artificial light. CodSELect will investigate fish behaviour in relation to artificial light in a further series of tank trials measuring behavioural responses to a range of different artificial light parameters including blue, green, red and white constant light or strobing light with a frequency of 1 Hz at 5 or 50%. The tank trial work feeds into two sea trials investigating if the addition of artificial light to the bottom panel of a trawl gear would modify the natural behaviour of cod, to stay low down in the trawl where they remain relatively inactive, by encouraging cod to swim up, increasing encounter rates with a Square Mesh Panel (SMP) positioned above and subsequently increase escape attempts of cod. |
