在白色海和巴伦支海盆地的四个地点分析了17- 18世纪历史文献中记录的大西洋鲑鱼（萨尔莫salar）的渔获量。大西洋鲑鱼是17- 18世纪俄罗斯北方地区最有价值的经济产品之一。因此，捕获量在国家部门和寺庙的账簿上有很好的记录。鲑鱼主要在河流的下游捕捞，使用的是几个世纪以来技术上没有改变的堰。这使得捕捞努力量可以统计，并允许将17- 18世纪的历史渔获量数据与19世纪最后25年以来的统计数据进行比较。不同季节鲑鱼的渔获量、平均重量和比例有显著波动。渔获量下降往往与相对较冷的时期相吻合。历史和统计数据的比较表明，大西洋鲑鱼的捕获量及其种群规模的变化很可能是由自然因素驱动的世纪中期之前。
Catches of Atlantic salmon, Salmo salar, recorded in historical documents from the 17–18th Centuries have been analysed in four locations in the basins of the White and Barents Seas. Atlantic salmon was one of the most valuable products of the local economy in the 17–18th Centuries in the northern Russia. Therefore, catches were well recorded in the account books of state departments and monasteries. Salmon were fished mostly in the lower parts of rivers, using weirs which technologically were not changed over the centuries. This makes fishing effort commensurable and allows comparison of historical catch data of the 17–18th Centuries with statistical data available since the last quarter of the 19th Century. Notable fluctuations of catches, average weight and ratio of different seasonal forms of salmon were revealed. Decreasing catches tended to coincide with relatively colder periods. Comparison of historical and statistical data has shown that catches Atlantic salmon and therefore changes in size of their populations were most probably driven by natural factors before middle of the 20th Century.
