Metadata: UK ICES fish stock and shellfish stock assessment data 2017
Abstract:
This dataset summarises stock assessment advice for quota fish stocks and national shellfish stocks. These files contain data quantifying annual recruitment, biomass, stock size, landings, catches, discards, industrial bycatch, fishing pressure (fishing pressure mean, ranges, and estimated pressure accountable to landings, discards and bycatch) and stock indicators (Flim fisheries mortality that if exceeded would result in the stock falling below Blim, Blim spawning stock Biomass at the limit reference point, Fpa level of catches that if exceeded would result in the stock falling below Bpa, Bpa spawning stock Biomass in relation to the precautionary approach, Fpa FMSY Maximum sustainable yield, BMSY Maximum sustainable yield biomass trigger) for various fish stocks (fish species in given ICES regions).

Centre for Environment, Fisheries and Aquaculture Science, Lowestoft Laboratory (CEFAS)

| Internal code | Internally assigned metadata identifier | 9612 |
| 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. | UK ICES fish stock and shellfish stock assessment data 2017 |
| 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. | CEFAS481eeb5d-f329-4de1-97da-2a296351d899 |
| Resource Identifier | This is the code assigned by the data owner. | CEFAS18741 |
| 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 | 1905-12-31 |
| End date | This describes the date the resource ends. This may only be the year if month and day are not known | 2017-01-01 |
| Spatial resolution | This describes the spatial resolution of the dataset or the spatial limitations of the service. | 600000 |
| Spatial resolution unit | This describes the unit of spatial resolution which for distance must be metres. | urn:ogc:def:uom:EPSG::9001 |
| 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'. | notPlanned |

| Lineage | Lineage includes the background information, history of the sources of data, data quality statements and methods. | The UKICESfishstockandshellfishstockassessmentdata_2017.csv is modified from the ICES stock assessment database. Appended to this is the UK national shellfish stocks data, which were taken from assessment reports provided by Cefas and Marine Scotland. In the dataset, the first column “ICES” identifies those stocks that originate from the ICES stock assessment database with the entry “Y”. The SPiCTStock data2281117.csv contains ICES stock assessment model outputs. SPiCT refers to 'Stochastic Production model in Continuous Time', the model used to produce outputs for data limited stocks. These data were not released online by ICES when this data were collated (12/09/2017), but instead downloaded directly by `www.stockassessment.org`_ (Casper Berg, DTU-Aqua) to Cefas on 08 June 2016. The ICESfishstockandshellfishstockassessmentdata2017columndescriptions.txt file contains column header descriptions. This indicator summarises stock assessment advice for quota fish stocks and national shellfish stocks. The input data for quota fish stocks arise from the ICES stock assessment database http://standardgraphs.ices.dk/stockList.aspx, while the data for national shellfish stocks arise from Marine Scotland and Cefas assessments, where data are provide per sex per stock both sexes had to be below Fmsy for the status per stock to be considered below Fmsy: Cefas (2015a).
