Channa punctatus responds to the intramuscular administration of cobalt chloride and cobalt nitrate by exhibiting an increase in the blood glucose level. The hyperglycemia persists till 120 h, after which the fish become moribund and ultimately die. Cobalt salts evoke degranulation and vacuolization of the alpha-cells in the initial stage but later the beta-cells are also found to be severely damaged. Cobalt chloride has been found to be more toxic than the cobalt nitrate.
斑点叉尾鮰对肌肉注射氯化钴和硝酸钴的反应是血糖水平升高。高血糖持续到120小时，之后鱼变得濒死并最终死亡。钴盐在初始阶段会引起α细胞脱粒和空泡化，但后来也发现β细胞受到严重损伤。已发现氯化钴比硝酸钴毒性更大。
