UK ICES fish stock and shellfish stock assessment data 2017
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).
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:
