dc.description.abstract实验室培养条件下,以新近孵化的卤虫(Artemiasalina)为食物,观测中华假磷虾(Pseudeuphau siasinica)雌性成体、仔虾和后期带叉幼体的碳氮收支.实验表明摄食率随食物浓度的升高呈线性提高,成体未出现饱和现象,反映其较高的摄食潜力.呼吸率(碳消耗率)与碳的摄食率及同化率分别呈线性正相关,比动力作用分别为9% ~16% (摄入碳)和10% ~17% (同化碳)以后期幼体更小.总氮排泄率与氮的摄食率及同化率也分别呈显著正相关,但仔虾例外.排粪率随摄食率升高而提高,从而同化效率与摄食率无关,介于0 84~0 95.食物氮源是中华假磷虾生长的主要限制因子,当摄食率低于10μg/(mg·d) (干重)时,假磷虾呈负生长.同化的氮以排泄消耗为主,体质生长次之,而蜕皮损失最少.同化的碳也以呼吸消耗和体质生长居多,但随摄食率有变化,蜕皮损失最少.在成熟雌体,估算的生殖生长(碳、氮)比蜕皮损失略高.净生长效率随摄食率(及同化率)升高而升高.达一定值后,仔虾和后期带叉幼体净生长效率略有下降. 【英文摘要】 The carbon and nitrogen budgets are estimated on the adult females, juveniles and post-furcilia larvae of Pseudeuphausia sinica in the laboratory with newly hatching nauplii of Artemia salina as food.It is found that the ingestion rate is linearly related to the food concentration, suggesting high feeding potential.The linear correlation can be established between the respiration rate (carbon consumption rate ) and carbon ingestion rate, as well as carbon assimilation rate.The regression coefficients ( i.e....zh_CN
