Abstract

article i nfo 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 diploid and triploid Atlantic salmon post-smolts (8 full-sib families) were influenced by isolated- or mixed-ploidy rearing during 12 months of sea water grow-out in tanks until harvest. Diploids attained significantly higher harvest weights than triploids in both treatments (+6.7% isolated, +26.3% mixed). Triploid harvest weight was 29.6% lower under mixed ploidy rearing than their isolated triploid siblings. A similar effect was also observed in diploids (12% lower harvest weight). Family had a significant effect on harvest weight in both ploidy. However, family harvest weight in trip- loids showed a linear relationship between isolated and mixed rearing (r 2 = 0.76), while a non-linear
