Legal minimum landing sizes of North Sea fish species under UK Statutory Instruments (SI) and European Council Regulations (CR) post-introduction of the Common Fisheries Policy in 1983.

SI and CR that merely maintained legal landing sizes at current values are not listed.*Although blue ling have an assigned legal minimum landing size, they are only rarely caught in the IBTS trawl surveys, so were included in the ‘other marketable’ species category for analysis with the reduced model.Legal minimum landing sizes of North Sea fish species under UK Statutory Instruments (SI) and European Council Regulations (CR) post-introduction of the Common Fisheries Policy in 1983.仅维持现行法定上岸尺寸的英国法定文书（Statutory Instruments，SI）与欧盟理事会法规（Council Regulations，CR）未被纳入本次数据集。*尽管蓝线鳕（blue ling）已被设定法定最小上岸尺寸，但在IBTS底拖网调查中极少被捕获，因此在简化模型的分析中被归入‘其他可上市物种’类别。本次数据集收录1983年共同渔业政策（Common Fisheries Policy）实施后，依据英国法定文书（SI）及欧盟理事会法规（CR）制定的北海鱼类物种法定最小上岸尺寸。
