Osmoregulation in Atlantic salmon Salmo salar smolts transferred to seawater at different temperatures
In order to investigate how changes in gill Na + , K + ‐ ATPase ( NKA ) α1a and α1b subunits, Na + , K + , 2Cl − co‐transporter ( NKCC1 ) and the apical cystic fibrosis trans‐membrane conductance regulator‐I ( CFTR ‐I) transcripts in wild strain of Atlantic salmon, Salmo salar , smolts are affected...
