鱼体能量含量的测定是鱼类能量学研究的一个重要内容。近来的研究表明,测定鱼体能量含量上的误差,是造成估算鱼类能量收支误差的一个重要原因。测定生物能量含量的最可靠的方法为用热量计(calorimeter)直接测定。但热量计价格昂贵,不易普及;测量中需用铂丝作引燃材料,成本较高;热量计的操作也较费时。一般测定鱼体能量含量的方法为: The determination of fish’s energy content is an important part of fish energy research. Recent studies have shown that measuring the energy content of fish is an important reason for estimating the error of energy expenditure of fish. The most reliable method of determining the bioenergy content is by direct calorimeter measurements. However, the calorimeter is expensive and not easy to popularize. The platinum wire needs to be used as the ignition material in the measurement, and the cost is high. The operation of the calorimeter is also time-consuming. The general method for determining the energy content of fish is:
