Metadata: Whitefish bycatch in sandeel fishing areas 2003/04 - Fisheries Science Partnership
Abstract:
Survey to measure the whitefish bycatch taken by a 16mm commercial sandeel net, fished at a time when juvenile gadoids could be settling around the Dogger Bank.
Data holder:
Centre for Environment, Fisheries and Aquaculture Science, Lowestoft Laboratory (CEFAS)

| Internal code | Internally assigned metadata identifier | 11153 |
| 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. | Whitefish bycatch in sandeel fishing areas 2003/04 - Fisheries Science Partnership |
| Alternative title | The purpose of alternative title is to record any additional names by which the dataset may be known. | FSP Whitefish bycatch in sandeel fishing areas |
| 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. | CEFASf98fd13a-be52-423e-a679-ba9abe49cb5a |
| Resource Identifier | This is the code assigned by the data owner. | CEFAS615 |
| 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 |

| Lineage | Lineage includes the background information, history of the sources of data, data quality statements and methods. | Sandeels are small, eel-shaped fish which require a fine mesh (<16mm) in order to retain them, thus increasing the probability that young fish of non-target species (including cod, haddock and whiting) could also be caught. The EU Technical Conservation Regulation restricts the fish by-catch to 5% by weight of all marine organisms on board, but a low weight of whitefish could still contain a significant number of young whitefish. Compliance with the EU Regulation is monitored by Danish and Norwegian authorities at the ports, where a sub-sample of the landing is taken and analysed for species composition, whilst monitoring at sea is carried out bym national inspectors, including those of the UK. It is possible that the effectiveness of port-based monitoring could be compromised by spoilage of small gadoid by-catches in the hold, and that monitoring at sea could be compromised by spatial patchiness, so there has been concern within the UK industry that the official by-catch data may not reflect the true extent of by-catches. This project therefore aimed to observe and record on a haul by haul basis the catch composition obtained when fishing a small meshed sandeel net at a time of the year when young whitefish of the year could conceivably be present in significant numbers on sandeel grounds. Some hauls were also carried out on nearby whitefish grounds using both a whitefish trawl and the sandeel trawl. The project used an English whitefish trawler, the Jubilee Quest, a relatively low power (465 hp) vessel of 22 m rigged with a commercially-manufactured 16 mm 3 mesh sandeel net made for the purpose in Denmark, or with the vessel’s own whitefish trawl with 100 mm cod-end. Two trips were undertaken, from 3-12 July and from 17-28 July, when 0-group gadoids might be present. Based on satellite records and other sandeel fishing information, the area of operation was chosen to be the western Dogger, and then further south on The Hills FSP Project 1, Undertaken in July 2003 with a fine-meshed net on sandeel grounds in the north-east Dogger Bank area of the North Sea. |
