Modeling foodweb dynamics and growth of juvenile Pacific salmon in the coastal marine ecosystems of BC

太平洋鲑鱼是加拿大重要的渔业资源，与区域和国家经济以及不列颠哥伦比亚省沿海社区和原住民的社会和文化遗产有着重要的联系。近几十年来，太平洋鲑鱼的产量一直在下降，有几个种群几乎消失。 虽然其内在机制尚不清楚，但人们越来越感到，这种下降可能与海洋条件的大规模变化以及由此造成的温度、营养物质、浮游动物、饲料鱼和捕食者群体的数量和质量的变化有关。目前，在预测和预报每年成年鲑鱼的回归方面存在很大的不确定性，这可能导致沿海社区的商业严重损失和不利的社会经济后果。我们的建议是理解和

Pacific salmon are an important fisheries resource for Canada, with significant links to both regional and national economies, and social and cultural heritage of BC's coastal communities and First Nations. In recent decades the productivity of Pacific salmon has been declining, with several stocks all but disappearing. Although the underlying mechanisms are still unclear, there is a growing sense that such declines may be linked to large-scale changes in ocean conditions and the resultant variability in temperature, nutrients, the quantity and quality of zooplankton, forage fish and predator assemblages. Currently there are significant uncertainties in the prediction and forecast of annual adult salmon returns, which can lead to significant loss of business and negative socio-economic consequences for coastal communities.
