Environmental effects on lipid nutrition of farmed Atlantic salmon (Salmo salar L.) parr and smolt
An experiment was conducted to investigate the effects of temperature, feed fat content and dietary oil source on growth and nutrient utilisation of Atlantic salmon parr (f 19 g). The fish were reared in freshwater at 2 or 8 jC for 6 months at light/dark cycles of 12 h:12 h. Each of four feeds was provided to triplicate groups of fish at each temperature. The feeds were formulated with marine f...
متن کاملInfluence of dietary lipid composition on cardiac pathology in farmed Atlantic salmon, Salmo salar L.
The present study investigated the short-term (5 months) effect of replacing dietary marine oils with vegetable oils on the development of arteriosclerotic changes in the heart of Atlantic salmon, Salmo salar. The experiment was performed as a randomized observer-blinded and controlled trial. Farmed Atlantic salmon were randomly sampled from a study population containing 900 individuals. The sa...
متن کاملAtlantic salmon – Salmo salar
Distribution Th e species’ range encompasses Europe, North America, and Green land (1) (Fig.1). Non-anadromous forms occur in Europe in a few land-locked locations in Norway and Sweden, and throughout the Neva/Lake Ladoga system and Karelia regions of Russia. In North America non-anadromous forms occurred throughout most of the species’ historical range, as far west as Lake Ontario, and remain ...
متن کاملDevelopment of intestinal ion-transporting mechanisms during smoltification and seawater acclimation in Atlantic salmon Salmo salar.
This study investigated the expression of ion transporters involved in intestinal fluid absorption and presents evidence for developmental changes in abundance and tissue distribution of these transporters during smoltification and seawater (SW) acclimation of Atlantic salmon Salmo salar. Emphasis was placed on Na(+) , K(+) -ATPase (NKA) and Na(+) , K(+) , Cl(-) co-transporter (NKCC) isoforms, ...
متن کاملEnvironmental and physiological factors shape the gut microbiota of Atlantic salmon parr (Salmo salar L.)
Gut microbes are key players in host immune system priming, protection and development, as well as providing nutrients to the host that would be otherwise unavailable. Due to this importance, studies investigating the link between host and microbe are being initiated in farmed fish. The establishment, maintenance and subsequent changes of the intestinal microbiota are central to define fish phy...
