渤海渔业种群鱼卵仔稚鱼检测数据集（2015-2017年）

渔业种群鱼卵仔稚鱼即调查海域中捕获的鱼卵、仔鱼、稚鱼，海上调查作业网具为水平网，野外取样后经鱼卵仔稚鱼专业人员鉴定后获得鱼卵、仔鱼、稚鱼数据；鱼卵仔稚鱼资源密度是判断渔业种群产卵场、育幼场的基础支撑材料，也是预测渔业种群补充群体资源密度的重要依据。该数据集中主要包括渤海海域2015年春季（5月）、夏季（8月），2016年冬季（1月）、春季（5月）、夏季（8月）、秋季（10月）及2017年春季（5月）、夏季（8月）鱼卵仔稚鱼监测数据，及三湾一河口（辽东湾、渤海湾、莱州湾及黄河口）海域2015年夏季（6月），2016年夏季（6月、7月）鱼卵仔稚鱼监测数据。

Fish eggs, larvae and juveniles of fishery stocks refer to those collected from the surveyed marine areas. The fishing gear employed in the marine survey operations is a horizontal net. The data on fish eggs, larvae and juveniles are acquired through field sampling and subsequent identification by professionals specializing in fish eggs, larvae and juveniles. The resource density of fish eggs, larvae and juveniles serves as a fundamental supporting basis for identifying the spawning grounds and nursery grounds of fishery stocks, and is also an important basis for predicting the resource density of the recruitment populations of fishery stocks. This dataset mainly includes monitoring data of fish eggs, larvae and juveniles collected from the Bohai Sea in May (spring) and August (summer) of 2015; January (winter), May (spring), August (summer) and October (autumn) of 2016; and May (spring) and August (summer) of 2017, as well as monitoring data of fish eggs, larvae and juveniles collected from the sea areas of the three bays and one estuary (Liaodong Bay, Bohai Bay, Laizhou Bay and the Yellow River Estuary) in June (summer) of 2015, and June and July (summer) of 2016.
