摘　　要：为构建紫海胆(Heliocidaris crassispina)动态能量收支模型,测定了紫海胆动态能量收支模型(dynamic energy budget,DEB)的5个关键参数。基于生物学参数测量,通过将壳径与结构物质重量回归拟合得到形状系数;采用循环水控温法获取不同温度下紫海胆的耗氧率,计算得到阿伦尼斯温度;通过饥饿耗能法获得单位体积维持能率等数值。结果表明,紫海胆的形状系数(δm)为0.815,阿伦尼斯温度(TA)为(5799.03±1372.69)K,紫海胆单位体积维持能率[P·M]为78.91 J·cm^(-3)·d^(-1),单位体积结构物质所需的能量[EG]值为13653.03 J·cm^(-3),单位体积最大储存能量[EM]值为4027.63 J·cm^(-3)。对不同规格紫海胆在不同温度下的耗氧量研究结果表明,紫海胆的耗氧率先随着温度的升高而增大,当温度为28℃时耗氧率达到最大,之后随着温度升高逐渐下降;不同规格紫海胆在16℃和22℃时耗氧率无显著差异(P>0.05),28℃时耗氧率差异极显著(P<0.01),34℃时耗氧率差异显著(P<0.05)。饥饿实验持续28 d,海胆内部组织有机物含量由92.08%下降到89.35%,内部组织干重稳定在0.67 g,耗氧率稳定在0.48 mg·h^(-1)·g^(-1) DW。研究获得5个构建紫海胆DEB模型的基本参数值,为后续构建紫海胆DEB模型提供了数据支持,并为进一步利用动态能量收支模型选择紫海胆增殖放流区域、增加紫海胆资源量奠定了基础。The dynamic energy budget model links the physiological status of organisms with the environment,describes the relationship between energy in the process of food intake,quantifies the distribution of energy in the maintenance,development,growth,and reproduction of organisms,and is a powerful tool for exploring how individuals respond to food supply,how organisms interact with the environment,and how they are influenced by multiple sources of stress.The measurement and calculation of model parameters are relatively complex,which affects the accuracy of the model and is crucial for subsequent establishment and application of the model.In order to construct a dynamic energy budget(DEB)model for Anthocidaris crassisoina,this study used biological coefficient measurements under laboratory conditions to regress and fit the shell diameter with the weight of structural materials to obtain the shape coefficient.The circulating water temperature control method was used to obtain the oxygen consumption rate of H.crassispina at different temperatures,and to calculate the Arennis temperature.Values such as unit volume maintenance energy rate were obtained.Five key parameters for measuring the dynamic energy budget model of H.crassispina were obtained,and the results showed that:the shape coefficientδm was 0.815,the Arenis temperature(TA)was(5799.03±1372.69)K,the oxygen consumption rate per unit volume[P·M]was 78.91 J·cm^(-3)·d^(-1),the energy required per unit volume of structural material[EG]was 13653.03 J·cm-3 and the maximum stored energy per unit volume[EM]was 4027.63 J·cm^(-3).The oxygen consumption test showed that the oxygen consumption rate increased with the increase of temperature,and gradually decreased after reaching the maximum at 28℃.There was no significant difference in the oxygen consumption rate of different specifications of H.crassispina at 16℃and 22℃(P>0.05).The oxygen consumption rate of different specifications of H.crassispina was extremely significant at 28℃(P<0.01),and there was a sign
