中文摘要:
      为获取皱纹盘鲍个体生长模型所需的6个关键参数,设计了饥饿耗能、温度对耗氧的影响等相关生理实验,计算得到各项参数值。单位体积维持耗能率的值〖[p ?〗_M]、形成单位体积结构物质所需的能量值[E_G]、单位体积最大储存能量[E_m]和储备能量值μ_E 4个参数通过连续测定皱纹盘鲍饥饿过程中呼吸耗氧率和软组织干重不断下降直至保持稳定时的能量值计算;温度函数中Arrhenius温度T_A的数值根据鲍在不同温度梯度下的单位干重耗氧率测定、计算;形状系数δm值通过统计测量的壳长、软组织湿重等生物学参数拟合回归得到。结果表明:(1)皱纹盘鲍在饥饿后,呼吸耗氧率和软组织干重分别降低了26.3%和70%,呼吸耗氧率由2.69 mg ind-1 h-1逐渐降低并稳定在0.8 mg ind-1 h-1,软组织干重由5.21±0.89 g降低至3.84±0.22 g;根据公式计算得出〖[p ?〗_M]和[E_G]的值分别为20.18 J cm-3 d-1和8120 J cm-3;鲍饥饿前后有机物含量分别为80%和58%,经过换算[E_m]和μ_E的值分别为2726 J cm-3和32583 J g-1。(2)不同规格的皱纹盘鲍在水温5-20℃范围内,温度与单位干重耗氧率呈正比;当水温超过20℃之后,温度与单位干重耗氧率呈反比。在转折点20℃之前,单位干重耗氧率的Ln值与温度(热力学温度,K)的倒数呈线性关系,线性回归方程斜率的绝对值为Arrhenius温度T_A值(T_A=7196 K)。(3)生物学统计分析鲍壳长(L)与体积(V)呈三次函数关系:V = 0.0639L3.1621(R2 = 0.9852),根据公式对软组织湿重的立方根与壳长进行线性回归,所得的斜率即为形状系数δm值(δm =0.43)。本研究对建立以DEB理论为指导的皱纹盘鲍个体生长模型提供了数据支撑。
英文摘要:
      Six key parameters for Dynamic Energy budget (DEB) model of Haliotis discus hannai Ino were obtained through physiological experiments on the influence of starvation on energy consumption, and the influence of temperature on oxygen consumption. The value of 4 parameters (Volume-specific maintenance costs 〖[p ?〗_M],Volume-specific costs for structure〖[E〗_G], Maximum storage density 〖[E〗_m] and Energy content of reserveμ_E) was calculated by measured energy when oxygen consumption rate and dry flesh weight decreased until they remained steady during the starvation period. The value of Arrhenius temperature (T_A) was determined by oxygen consumption rate of abalone per unit dry weight under different temperature gradients; The value of shape coefficient (δm) was calculated by regression equation based on data of length and body mass. The results showed: (1) After the starvation experiment, the value of dry flesh weight and oxygen consumption rate decreased by 26.3% and 70% respectively. Meanwhile, the oxygen consumption rate goes from 2.69 mg ind-1 h-1 to 0.8 mg ind-1 h-1, and stays at this level, the dry flesh weight falls from 5.21±0.89 g to 3.84±0.22 g. Calculated according to the formula, the values of 〖[p ?〗_M] and [E_G] were 20.18 J cm-3 d-1, 8120 J cm-3, the content of organic matter before and after starvation respectively was 80% and 58%, through conversion organic content, the values of [E_m] and μ_E were 2726 J cm-3, 32583 J g-1; (2) For abalone at different sizes, temperature was proportional to the oxygen consumption rate at water temperatures of 5-20°C, and the temperature is inversely proportional to the oxygen consumption rate over 20°C. Before the turning point of 20°C, The ln value of the oxygen consumption rate was linearly correlated to the reciprocal of thermodynamic temperature, and the absolute value of the slope of the linear regression equation was the Arrhenius temperature T_A value (T_A=7196 K) before the turning point (20 °C).(3) By biological statistical analysis, there is a cubic function relationship between abalone shell length (L) and volume (V): V = 0.0639L3.1621 (R2 = 0.9852), The slope is seen as the Shape coefficient δm value (δm = 0.43) that calculated by the equation of volume of the cube root and shell length linear regression. This study provides data support for the construction of an individual-based model following the DEB theory for Haliotis discus hannai Ino.
