Circulatory strain, energy output and urinary catecholamine excretion were determined in 24 coastal, 6 trawler, 5 bank and 3 capelin fishermen. From these studies it is evident that fishing may represent hard physical work. However, if properly organized with job rotation and adequate creq numbers, it may, in some respects, be comparable with many occupations ashore. The introduction of mechanization and automation has led to increased tempo and greater stress. Consequently, the older fishermen, due to declining physical work capacity, may find it difficult to keep up with their younger colleagues. Yet, the official Norwegian statistics show that the percentage of older fishermen is increasing.
对24名沿海渔民、6名拖网渔船渔民、5名岸钓渔民和3名毛鳞鱼渔民的循环系统应变、能量输出和尿儿茶酚胺排泄情况进行了测定。从这些研究中可以明显看出，捕鱼可能是一项艰苦的体力劳动。然而，如果通过轮岗和足够的船员数量进行合理组织，在某些方面，它可能与岸上的许多职业相当。机械化和自动化的引入导致了节奏加快和压力增大。因此，年长的渔民由于体力下降，可能会发现难以跟上年轻同事的步伐。然而，挪威官方统计数据显示，年长渔民的比例正在增加。
