摘要
为研究不同沉积物对南移刺参的影响,测定了南移刺参对三种不同沉积物(海区沉积物、对虾养殖池沉积物、人工配制沉积物)的摄食,吸收效率和能量收支。结果表明,规格为26.11±1.5g的南移刺参在温度为17±1℃时,不同组别南移刺参对不同种沉积物的摄食率无显著差异(P>0.05),对虾组和人工组南移刺参同化效率和特定生长率显著高于海区组(P<0.05),且对虾组同化效率和特定生长率最高。通过对能量收支方程的探究,各组别代谢能无显著差异(P>0.05),对虾组南移刺参生长能显著高于其他两组(P<0.05),其能量收支方程为:100C=12.35G+34.91F+8.05U+44.69R。研究表明,特定养殖条件下,用虾塘沉积物喂食南移刺参时,刺参摄食能量较多的分配至生长,生长速率较快,利用虾塘沉积物作为饵料是一种可取模式。
We investigated the feeding rate,absorption efficiency and energy budget of Southern-China-cultured Stichopus japonicus fed with three different sediments(from sea area,shrimp-culture pond and artificial sediments) to understand the influence of sediments on s Southern-China-cultured.The results demonstrated that there was no significant difference in the feeding rate among 3 types of sediments(P>0.05) when S.japonicus acclimatized in southern China was with 26.11±1.5 g weight under temperature of 17±1 ℃.Assimilation efficiency and SGR in artificial sediments and shrimp-culture pond groups were significantly higher than in the sea area group(P<0.05).Meanwhile,the greatest assimilation efficiency and SGR occurred in the shrimp culture pond sediments group.Through researching on the equation of the energy budget in different groups,we found that the metabolic energy in different groups had no significant difference(P>0.05).The ratio of growth energy in shrimp-culture pond group was significantly greater than another two groups(P<0.05).The energy budget equation could be concluded as 100C=12.35R+34.91G+8.05UF+44.69R.The research indicated that using sediments of shrimp pool under certain breeding circumstance,FR of S.japonicus distributed more to growth and the growth rate was comparatively high.Therefore,it is advisable to use sediments of shrimp pool to feed S.japonicus.Therefore,using sediments of shrimp pool to feed S.japonicus was apparently an advisable model.
