Photoperiodic effects on precocious maturation, growth and smoltification in Atlantic salmon, Salmo salar
Current Atlantic salmon farming practice induces early smoltification with artificial photoperiod regimes, however the importance of these photoperiods on parr maturation and interactions with smoltification are poorly understood. These questions were addressed in the present investigation, which ex...
