Abstract: 静岡水試富士養鱒場で継代選抜中の IHN 耐病系統から得られた 2 系統の第一卵割阻止型クローンを用いて形質の評価を行ったところ,耐病性および再生産形質は異なる特徴を有していた。すなわち,RT92H10 は IHN に対する抵抗性が高いもののビブリオ病に対する抵抗性が低く,RT92H04 はその反対であった。再生産形質について RT92H04 では成長は遅いが 2 年で成熟し,RT92H10 は成長は比較的早いものの成熟までに 3 年を要した。以上の結果から,これら 2 系統は育種素材や免疫学的実験魚としての利用が期待された。
Two rainbow trout strains (RT92H04 and RT92H10) were gained by chromosome manipulation from infectious hematopoietic necrosis (IHN) tolerant selected rainbow trout at Fuji Trout Hatchery, Shizuoka Prefectural Fisheries Experimental Station. Disease tolerance and reproduction trait of these strains were investigated. Though IHN tolerant, RT92H10 had low resistance to Vibrio anguillarum infection. On the other hand, RT92H04 was V. anguillarum infection tolerant and had low resistance to IHN. RT92H04 grew slowly but matured at the age of two. RT92H10 took three years to mature, although it grew relatively fast. These results revealed that these strains may be useful as breeding stock or immunological experimental fish.
