The effect of porcine somatotropin on growth, and survival in seawater of Atlantic salmon ( Salmo salar ) parr
The effects of porcine growth hormone on growth and salinity tolerance were studied in Atlantic salmon (Salmo salar) parr. Fish were held in freshwater at 11.5 °C during June and July under a photoperiod with light to dark periods opposite to the prevailing natural conditions. Fish treated with 1.0...
