【摘要】 不同盐度(21、25、29、33、37、41)条件下,室内养殖九孔鲍(Haliotis diversicolor aquatilis)实验结果表明:盐度21-37时,九孔鲍的生长能和代谢能随盐度的增加而增加;盐度高于37时,九孔鲍的生长能和代谢能却随盐度的增加而降低。在盐度为37时,九孔鲍的代谢能和生长能均达到最大值。在盐度为21、25、29、33、37、41时,九孔鲍的能量收支方程为:100(C)=17.73(F)+9.09(U)+18.75(M)+43.18(R)+0.24(Psh)+19.88(Pg)-8.87100(C)=14.36(F)+7.44(U)+7.45(M)+34.31(R)+0.72(Psh)+27.39(Pg)+4.39100(C)=15.34(F)+5.75(U)+7.39(M)+36.44(R)+1.94(Psh)+26.02(Pg)+8.33100(C)=15.34(F)+5.75(U)+7.39(M)+36.44(R)+1.94(Psh)+26.02(Pg)+7.12100(C)=12.23(F)+7.96(U)+10.87(M)+33.99(R)+2.20(Psh)+28.91(Pg)-1.16100(C)=10.80(F)+7.79(U)+12.81(M)+35.43(R)+1.531(Psh)+22.36(Pg)+9.27但能量收支方程式的结果表明,对于鲍的代谢能占总摄食能之比例,除盐度21组与其他各组之间有显著差异外(P<0.05),其余各组之间却无明显差异(P>0.05)。而对于各组鲍的总生长效率K1与与净生长效率K2而言,盐度21、41组分别与25、29、33、37组之间均有显著差异(P<0.05);盐度25、29、33、37各组之间无显著差异(P>0.05)。因此,从试验误差,鲍的摄食能、代谢能和生长能三方面的均衡考虑,盐度25—37的为鲍适宜养殖的范围。从上达能量收支方程中看出,九孔鲍绝大部分能量用于代谢,一部分能量用于软体部的生长和排粪,还有一小部分用于排泄和分泌粘液,只有极小部分能量用于生长壳。更多还原

【Abstract】 Under the simulated natural condition, the results of indoor aquarium culture of Haliotis diversicolor aquatiliis in 6 groups at the salinity of 21,25,29,33,37 and 41 suggested that, when the salinity of sea water increased from 21 to 37, the growth energy and the metabolic energy increased with the salinity, but when the salinity was beyond this range, they all decreased. When the salinity was 37, both the growth energy and the metabolic energy of Haliotis diversicolor aquatilis was maximum, When the salinities were 21,25,29,33,37 and 41, the formulae of energy budgets of Haliotis diversicolor aquatilis were as the following respectively 100(C)=17.73(F)+9.09(U)+18.75(M)+43.18(R)+0.24(Psh)+19.88(Pg) -8.87 100(C)=14.36(F)+7.44(U)+7.45(M)+34.31(R)+0.72(Psh)+27.39(Pg)+4.39 100(C)=15.34(F)+5.75(U)+7.39(M)+36.44(R)+1.94(Psh)+26.02(Pg)+ 8.33 100(C)=15.34(F)+5.75(U)+7.39(M)+36.44(R)+1.94(Psh)+26.02(Pg)+ 7.12 100(C)=12.23(F)+7.96(U)+10.87(M)+33.99(R)+2.20(Psh)+28.91(Pg) -1.16 100(C)=10.80(F)+7.79(U)+12.81(M)+ 35.43 (R)+1.531(Psh)+22.36(Pg)+9.27 The results of the energy budgets formulae showed that the differences of the proportions of the metabolic energy to ingestion energy between different groups (except group 21) were not significant (P>0.05). The differences of the total growth efficiency (K1) and (K2) of group 21, 41 between that of group25、29、33 、37 were significant respectively (P<0.05),while the differences of the total growth efficiency (K1) and (K2) among group 25、29、33 、37 were not significant (P>0.05), therefore, it is comprehensively suggested that the suitable salinity range of the abalone culture was from 25 to 37. According to the formulae, it was concluded that the most part of ingestion energy was used for metabolism, a part of energy for somatic part growth and feces, only a little part for excretion and mucus, and few part for shell growth.更多还原
