中文摘要: |
以山东烟台分叉小猛水蚤(Tisbe furcata)为研究对象,对比饲料中添加海泥对桡足类养殖水体
三氮一磷(亚硝态氮、硝态氮、氨氮和磷酸盐)以及桡足类种群密度的影响,探索北方室内桡足类大规模、高
密度养殖技术。结果表明,较添加海泥的复合饲料,单纯利用复合饲料进行分叉小猛水蚤的室内养殖效果更好
(P<0.01),表明桡足类不能直接利用海泥中的营养成分;水体三氮一磷中,亚硝态氮含量最为重要,在桡足
类快速增长期其含量与本地桡足类密度呈极显著正相关,后期浓度超过0.4 mg/L 时,对桡足类生长产生抑制
作用,因此需要严格控制;磷酸盐含量与桡足类密度呈极显著正相关。 |
英文摘要: |
Tisbe furcata was cultured indoor in cement pools in seahorse teaching and researching base of
Ludong University in Yantai city,Shandong province,China. By fed feed adding different amount of sea mud,
the community densities of T. furcata were compared and the relationship between community density and water
environmental factors,such as nitrite,nitrate,ammonia nitrogen and phosphate,were analyzed. The results showed
that the community density of T. furcata fed by feed without adding sea mud was significantly higher(P<0.01),
which implied that high community density of copepods naturally growing in the sea cucumber breeding ponds could
not directly use sea mud as their feed. Among nitrite,nitrate,ammonia nitrogen and phosphate,nitrite represented
the most important one,because it was significantly correlated with copepods’ community density at the beginning.
While when its concentration exceeded 0.4 mg/L,it would inhibit the growth of copepods. Therefore,nitrite should be
monitored carefully during the aquaculture process. Phosphate was significantly correlated with copepods’ community
density during its breeding. |
