浙江近海渔场是冬季带鱼的主要生产渔场。每年冬汛其产量约占全年产量的60%以上,特别是在大、小黄鱼资源衰竭后,对冬汛带鱼资源的利用也就更见重要。其生产的好坏、产量的丰欠直接影响水产品市场的供求。因此,研究冬汛带鱼产量波动的原因是很有必要的。 影响带鱼产量波动的因子很多,太阳活动、天气系统、气象条件是诸多影响因子中的一组环境因子。本文旨在根据1961~1982年浙江渔场冬汛带鱼产量资料、南京紫金山天文台的太阳黑子资料以及观测气象站有关气象参数的统计,初探带鱼产量丰欠年的环境条件以及它们之间的关系。
Zhejiang offshore fishing ground is the main production of hairtail fisheries in winter. Annual winter floods output accounts for about 60% of the annual output, especially in large and small yellow croaker resources, the utilization of winter octopus resources is even more important. Its production is good or bad, yield owed a direct impact on the aquatic products market supply and demand. Therefore, it is necessary to study the fluctuation of yield of hairtail in winter flood season. There are many factors that affect the yield of the octopus. Solar activity, weather system and meteorological conditions are a group of environmental factors among many influencing factors. The purpose of this paper is to investigate the environmental conditions of the octopus production and the relationship between them in the light of the statistics of the winter floods of Zhejiang fisheries from 1961 to 1982, the sunspot data of the Nanjing Purple Mountain Observatory and the meteorological parameters of the observed weather stations.
