在银鲑（Oncorhynchus kisutch）鱼苗中发现了三种可分离的血红蛋白。十血红蛋白的形式被发现在少年和成年鲑鱼。在饲料中加入12 ppm的三碘甲腺原氨酸（T3）处理一岁鲑鱼，加速了成年形式血红蛋白浓度的增加，而4 ppm的T3处理则没有效果。饮食丙基硫氧嘧啶（1.5或5毫克/克）减少增加的成人形式的血红蛋白在银化。这些结果暗示甲状腺激素在幼鲑幼鱼向二龄鲑转化过程中表达成人形式的血红蛋白。
Three electrophoretically separable forms of blood hemoglobin were found in fry of coho salmon (Oncorhynchus kisutch). Ten hemoglobin forms were found in juvenile and adult salmon. Treatment of yearling salmon with triiodothyronine (T3) at 12 ppm in the diet accelerated the increase in concentration of adult forms of hemoglobin, while treatment with T3 at 4 ppm had no effect. Dietary propylthiouracil (1.5 or 5 mg/g) reduced the increases in adult forms of hemoglobin during smoltification. These results implicate thyroid hormones in the expression of adult forms of hemoglobin during the parr to smolt transformation of juvenile salmon.
