The efficient commercial production of Arctic charr is hampered by the limited and subtle sexual dimorphism shown by this species. This project examined the feasibility of low-cost videoendoscopy through the genital pore to determine sex, stage of maturity, and safety for 80, randomly selected, anesthetized Arctic charr. The sensitivity and specificity for correct assignment of male sex were 90% and 100%, respectively, among 3 observers in a single-blind design. Sensitivity and specificity for relative sexual maturity in the same fish were 96% and 54%, respectively. The observed mortality rate of 7% at the end of 3 weeks was confounded by the presence of unrelated disease. We conclude that the technique holds promise for application by producers to improve production efficiency.
北极红点鲑有限且不明显的两性异形阻碍了其高效商业化生产。本项目研究了通过生殖孔进行低成本视频内窥镜检查以确定80条随机选取的麻醉北极红点鲑的性别、成熟阶段和安全性的可行性。在单盲设计中，3名观察者对雄性性别正确判定的敏感度和特异度分别为90%和100%。同一批鱼相对性成熟度的敏感度和特异度分别为96%和54%。3周结束时观察到的7%死亡率受到无关疾病存在的干扰。我们得出结论，该技术有望被养殖者应用以提高生产效率。
