Triploid Atlantic salmon growth is negatively affected by communal ploidy rearing during seawater grow-out in tanks
Using sterile triploid salmon is of interest to fish farmers as a means to mitigate interbreeding between farmed and wild fish, prevent pre-harvest maturation and offer potential for faster growth. We investigated within the same experiment whether growth, deformity and cataract prevalence in diploi...

Using sterile triploid salmon is of interest to fish farmers as a means to mitigate interbreeding between farmed and wild fish, prevent pre-harvest maturation and offer potential for faster growth.
