摘要
研究了用瓦片参礁池塘养殖刺参(Apostichopus japonicus)的底层溶氧条件和呼吸环境;测定获得11.5~15.3℃时,新、老池塘瓦片参礁的平均增氧量分别为1.96mgO_2/Ld与3.15mgO_2/Ld(或1.17 gO_2/m^2d与2.30 gO_2/m^2d),相应底栖硅藻生物量为14.61 g/m_2与48.55 g/m^2;统计获得底层溶解氧与底栖藻类的相关系数为0.85;推算得瓦片参礁上底栖硅藻对底层溶氧的贡献为2004年建池塘时:10.11~11.44mgO_2/Ld;2005年建池塘时:8.22~8.25mgO_2/Ld);分析了新、老池塘底层呼吸环境的差异;为刺参的池塘养殖模式提供了重要的理论依据。
The dissolved oxygen contents and respiratory oxygen consumptions of the tiles attachment in the bottom of the ponds were studied for Apostichopus japonicus cultivation. The results are as follows: when temperature were 11. 5℃- 15. 3℃ the increased oxygen contents were 1.96 mgO2/Ld and 3. 15mgO2/Ld (1. 17 gO2/m^2d and 2.30 gO2/m^2d) The benthic diatoms were 14.61 g/m^2 and 48.55 g/m^2 in the bottom water of pond in 2005 year and 2004 year, respectively. The correlation coefficient between DO of bottom water and biomass of benthic algae was 0.85. The biomass of benthic diatoms on the tiles attachment was calculated and its contribution to the bottom oxygen content was detected, which were 10.11 -11.44 mgO2/Ld in the pond in 2004 year and 8.22-8.25 mgO2/Ld in the pond in 2005 year. The differences of the respiratory environments in the bottom of the new and old ponds were compared, it throw great light on the patterns of A. japonicus cultivation in pond.
