Symptoms indicating digestive malfunction have been observed in cultivated salmon over
the last 10–15 years, at least partially as a consequence of use of new feed ingredients. The …

Using biochemical and molecular biological techniques, we describe the expression of
several key digestive enzymes throughout the ontogeny of larval haddock and Atlantic cod …
