【摘要】 采用封闭式呼吸器研究了虾夷马粪海胆（Ｓｔｒｏｎｇｙｌｏｃｅｎｔｒｏｔｕｓｉｎｔｅｒｍｅｄｉｕｓ）的耗氧率和排氨率与温度和盐度的关系。结果表明：在温度１５～２５℃的范围内，耗氧率和排氨率随温度的升高而增加；相同温度下，随个体重量的增加耗氧率和排氨率下降，呈负指数关系；虾夷马粪海胆的适宜盐度为３０左右，此时的耗氧率最大，为０．０９１ｍｇ／ｇ·ｈ，排氨率最低，为２３．６２μｇ／ｇ·ｈ。更多还原

【Abstract】 The tests were conducted at 15,20,25℃and salinity 20,25,30,35.The oxygen consumption rate and NH 3 excretion rate increased significantly with increasing of water temperature,and decreased with increasing of body weight.The indices above were significantly affected by salinity levels.The maximum oxygen consumption rate was 0.091mg/g·h, and the minimum NH 3 excretion rate was 23.62μg/g·h at salinity 30.更多还原
