虽然三倍体大西洋鲑鱼代表了鲑鱼养殖业中与性成熟相关问题的一种实用和负担得起的解决方案，但经验证据表明，三倍体比二倍体更容易受到疾病和疫苗副作用的影响。由于疫苗接种现已成为常规畜牧业的一部分，因此必须研究它们的反应，以确认它们是否适合商业化生产。本研究测试了三倍体和二倍体大西洋鲑鱼对市售疫苗接种的反应。对三倍体和二倍体大西洋鲑鱼兄弟姐妹注射三种商业疫苗（或假疫苗）中的一种，并在整个商业生产周期内监测其表现。在孵化和收获时进行采样，并在整个周期内对个体体重和长度进行评估。两倍体对杀鲑气单胞菌疫苗的抗体反应相似，在注射疫苗的鱼中呈阳性反应。对于粘连和黑色素，分析发现，随着疫苗预期严重程度的增加，得分越高。此外，在孵化和收获时的粘附分数和黑色素分数方面，三倍体在统计上比二倍体更有可能表现出更高的分数。三倍体在淡水期间和海水转移后11个月保持显著较高的体重，二倍体在收获时体重显著增加。以热生长系数（TGC）为代表的生长随黏附程度的增加而降低，两倍体间的回归模式无显著差异。三倍体椎体畸形患病率（初始值为12.3±4.5%，收获值为34.9±5.9%）始终高于二倍体（初始值为0.8±0.5%，收获值为15.9±1.9%），各倍体疫苗组间无显著差异。该研究表明，三倍体对疫苗接种的反应与二倍体一样好，并为商业水产养殖提供了三倍体稳健性的进一步支持证据。
While triploid Atlantic salmon represent a practical and affordable solution to the issues associated with sexual maturation in the salmonid aquaculture industry, empirical evidence suggests triploids are more susceptible to disease and vaccine side-effects than diploids. With vaccination now part of routine husbandry, it is essential their response be studied to confirm their suitability for commercial production. This study tested the response of triploid and diploid Atlantic salmon to vaccination with commercially available vaccines. Triploid and diploid Atlantic salmon siblings were injected with one of three commercial vaccines (or sham-vaccinated) and monitored for performance throughout a commercial production cycle. Sampling at smolt and harvest was undertaken along with individual weight and length assessments through the cycle. Antibody response toAeromonas salmonicidavaccination was similar in both ploidy, with a positive response in vaccine-injected fish. For both adhesions and melanin, analysis found that higher scores were more likely to occur as the anticipated severity of the vaccine increased. In addition, for adhesion scores at smolt and melanin scores at smolt and harvest, triploids were statistically more likely to exhibit high scores than diploids. Triploids maintained a significantly higher body weight during freshwater and until 11 months post-seawater transfer, with diploids weighing significantly more at harvest. Growth, represented by thermal growth coefficient (TGC), decreased in both ploidy as the severity of adhesions increased, and regression patterns did not differ significantly between ploidy. Vertebral deformity prevalence was consistently higher in triploids (smolt 12.3 ± 4.5%; harvest 34.9 ± 5.9%) than diploids (smolt 0.8 ± 0.5%; harvest 15.9 ± 1.9%), with no significant difference between vaccine groups in each ploidy. This study demonstrates that triploids respond as well to vaccination as diploids and provides further supporting evidence of triploid robustness for commercial aquaculture.
