IMPRESS – Improved production strategies for endangered freshwater species


Atlantic salmon

Although the Atlantic salmon has a long history of being cultivated and is the most import aquaculture species in Europe, current production regimes are not optimal for wildtype conditioning. Throughout its geographical range, every river had its own unique population(s) of salmon.

Human impact, especially in the southern range of the species’ natural distribution has caused several populations to become extinct while many other populations are vulnerable or endangered. New production strategies ensuring a good match between physiological and environmental windows of downstream migration as well as suitable feeding and migration behaviors are needed to rear juveniles of a quality required for environmentally sustainable stock enhancement programmes.
