简要回顾了导致野生大西洋鲑鱼种群数量急剧下降的主要因素，描述了稳定或增强因子以养护和扭转鲑鱼种群数量下降以及其他鲑鱼物种数量下降的主要需要。回顾了大西洋鲑鱼生活史中决定对栖息地退化反应的生理和所需栖息地特征的某些方面。人为发展，包括对淡水栖息地迁徙和退化的阻碍，是资源减少的主要原因。因此，栖息地是保护和恢复时要考虑的主要因素。社会经济考虑可能凌驾于生态和公共利益考虑之上，加拿大举了例子，那里的环境法规已经放松，有利于经济利益。公众教育、意识和宣传，以便为……争取政治意愿。
A short review is presented on the major factors contributing to recent precipitous declines in populations of wild Atlantic Salmon Salmo salar, with the approach of describing the major needs for stabilizing or enhancing factors to conserve and reverse the decline of salmon populations and incidentally of other salmonid species. Some aspects of physiology and required habitat characteristics through the life history of Atlantic Salmon are reviewed that determine responses to degradation of habitats. Anthropogenic developments, including obstructions to migration and degradation of freshwater habitats, are major reasons for declines in the resource. Thus, habitat is a primary factor to be considered in conservation and restoration. Socioeconomic considerations may override ecological and public interest concerns, and examples are given from Canada, where environmental regulations have been relaxed in favor of economic interests. Public education and awareness and advocacy in order for political “will” for...
