Abstract

Triploid cherry salmon (Oncorhynchus masou) were induced by the heat shocking treatment of fertilized eggs 10 minutes post fertilization at $28^{\circ}C$ for 15 minutes. Haematological and physiological characteristics of diploid and the induced triploid fish were examined just before the spawning period. Triploids had significantly lower concentrations of circulating red blood cells than that of diploids (P<0.01). However, oxygen consumption, hematocrit, hemoglobin, RBC, and mean concentration of hemoglobin within the RBC of triploids were higher than those of diploids. The concentrations of total protein, albumin and cholesterol from triploids were also higher than those from diploids.

수정 10분후에 수온 $28^{\circ}C$에서 15분간 처리로 산천어, Oncorhynchus masou 3배체를 유도하였다. 혈액학적 및 생리학적 특성 조사가 3배체와 2배체를 대상으로 산란기전에 실시되었다. 적혈구 수에서 3배체는 2배체에 비해 유의하게(P< 0.01) 낮은 반면 산소 소모, haematocrit치, hemoglobin, 적혈구 부피, MCH 및 MCHRBC에서는 3배체가 2배체에 비해 높게 나타났다 Total protein, albumin 및 cholesterol에서도 역시 3배체는 2배체에 비해 높게 나타났다.
