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).

本数据集概述了针对配额鱼类种群和国家贝类种群进行资源评估的建议。这些文件包含了量化年度补充量、生物量、种群规模、渔获量、捕捞量、丢弃量、工业捕捞副产品、捕捞压力（捕捞压力均值、范围以及与渔获量、丢弃量和副产品相关的估计压力）以及种群指标（若超过则会使得种群降至Blim以下之Flim渔业死亡率，Blim繁殖种群生物量在极限参考点，Fpa超出会导致种群降至Bpa以下之捕捞水平，Bpa繁殖种群生物量与预防性方法的相关性，FMSY最大可持续产量，BMSY最大可持续产量生物量触发器）的相关数据，涉及多种鱼类种群（特定ICES区域内的鱼类物种）。
