摘要: 本文通过在实验室条件下模拟方斑东风螺(Babylonia areolata)养殖池离底铺沙模式,对比了不同进水和排水方式对养殖池水更换效果的影响。结果表明,在上进下排类型中,不同进水方式对沙层下方水体的更换效果没有显著差异(P > 0.05),不同排水方式对沙层下方水体的更换效果影响有显著差异,其中,中间单孔排水效果最好(P < 0.05)。反渗进水的侧壁排水模式对沙层下方水体的更换速度显著快于单侧进水的中间单孔排水模式(P < 0.05),但对整个水体的更换速度则慢于单侧进水的中间单孔排水模式(P < 0.05)。单侧进水的中间单孔排水模式可以有效的利用流水将沙层中累积的有机物(如排泄物、残饵等)及产生的氨氮和硫化氢等冲洗掉,保持东风螺栖息沙层洁净。
Abstract: In this paper, the effects of different water inflow and outflow designs on water changing efficiency of Babylonia areolata farming pond were compared by simulating the sand-on-bottom-shelve model of Babylonia areolata farming pond under laboratory conditions. The results showed that there were no significant differences in water changing efficiency between different water inflow methods (P > 0.05), but there were significant differences between different outflow methods, and the middle single hole outflow design was most efficient in changing the water body under the sand layer (P < 0.05). The results also showed that the water changing speed of side wall outflow with reverse water seepage in-flow model is significantly faster than that of the middle single hole outflow model with single side water inflow (P < 0.05), but the water changing speed of the whole water body is slower than that of the middle single hole outflow with unilateral inflow model (P < 0.05). The middle single hole outflow with single side inflow model can effectively rinse the accumulated organic matters such as excreta, residual bait, ammonia nitrogen and hydrogen sulfide in the sand layer, and keep the sand layer clean.
