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 bottom aerobic conditions and respiratory environment of Apostichopus japonicus were studied. The average oxygen uptake of reefs in new and old ponds obtained from 11.5 to 15.3 ℃ were 1.96 mg O 2 / Ld and 3.15mgO_2 / Ld (or 1.17gO_2 / m ~ 2d and 2.30gO_2 / m ~ 2d), the corresponding benthic diatom biomass was 14.61g / m_2 and 48.55g / m ~ 2, respectively. The correlation coefficient of the algae was 0.85. The contribution of benthic diatoms to the underlying dissolved oxygen was estimated to be 10.11 ~ 11.44 mgO 2 / Ld when pond was built in 2004 and 8.22 ~ 8.25 mgO 2 / Ld). The differences of the respiratory environment in the bottom of the new pond and the old pond were analyzed. It provided an important theoretical basis for the pond culture pattern of the sea cucumber.
