Norfish Danish Sound Herring Fishery 1368–1790

The Øresund was of vital strategic importance as it provided the conduit between the North Sea and the Baltic Sea; the Danish Crown held the territorial advantage that enabled financial gain from taxing passing trade vessels into and out of the Baltic; in fact, the Danish Sound Toll records provide a great deal of detail about the import of herring from the North Atlantic herring fisheries, particularly the Dutch and Norwegians bound mostly for the Hanseatic Baltic ports. They do not, however, contain any information about the actual Danish herring fishery that took place in the Sound. The evidence for this fishery is patchy and while it is possible to assess the scale of the fishery at certain times, there is no sequential data.

厄勒海峡（Øresund）作为连接北海与波罗的海的关键通航水道，具备至关重要的战略地位。丹麦王室凭借其领土控制权，可对进出波罗的海的过往贸易船只征收关税，以此获取经济收益。事实上，丹麦松德关税档案（Danish Sound Toll Records）中留存了大量关于从北大西洋鲱鱼渔场进口鲱鱼的细节记录，其中尤以主要驶往汉萨同盟波罗的海港口的荷兰与挪威籍商船的相关内容为多。但该档案并未收录在厄勒海峡海域开展的丹麦本土鲱鱼捕捞活动的相关信息。目前关于该捕捞活动的史料较为零散，虽可对特定时期的捕捞规模进行估算，但缺乏连续序列的统计数据。
