摘要：

研究了凡纳滨对虾高位池生态系统的能量转化效率与养殖容量，结果表明：实验虾池浮游植物数量变化范围为3.45×107～1.71×108 cell?L-1。虾池水柱毛初级生产量变化在1.28～11.38 g?m-2?d-1之间。虾池生态系统中毛初级生产量为11573.30 MJ、投饵能为32663.62 MJ、施肥能量为229.71 MJ、放养虾苗折合能量为1.43 MJ，总投入能量为44468.04 MJ；虾池对虾收获能为5269.12 MJ；凡纳滨对虾高位池能量转化效率为11.85％。以氮负荷量估算虾池养殖容量为157万尾?hm-2。

Abstract:

The energy conversion efficiency and carrying capacity were studied in three higher-altitude Litopenaeus vannama culture ponds. The results showed that the mean value of phytoplankton quantity were 9.79×107 cell?L-1, ranging from 3.45×107 cell?L-1 to 1.71×108 cell?L-1. The mean value of primary productivity were 5.27 g?m-2?d-1, ranging from 1.28 g?m-2?d-1 to 11.38 g?m-2?d-1. Gross primary production was 11573.30 MJ, feeding energy was 32663.62 MJ, fertilizer energy was 229.71 MJ, fry energy of stocking was 1.43 MJ and harvest energy was 5269.12 MJ, total input energy was 44468.04 MJ. The energy conversion efficiency was 11.85％ in higher-altitude Litopenaeus vannama culture ponds. At the same time, estimation of carrying capacity by the toal nitrogen load was 157×104 larvae?hm-2
