泥鳅芡实共作对水质及泥鳅生长性能的影响
|
摘要
为了研究泥鳅芡实共作养殖池塘的水质和泥鳅的生长情况。通过水化分析,浮游生物检测及泥鳅生长指标测量,结果表明:试验期间,池塘内水温平均为26.6℃,透明度为23.2cm,溶解氧为4.8～5.6mg/L,pH为7.6～8.3,NH4+-N为0.51～0.69mg/L,COD为23.3～31.4mg/L;共检测到浮游植物5门24属(种),优势种为蓝藻门中的微囊藻属(Microcyslis)。浮游植物数量为6.49～13.84×10~6 ind/L,生物量为17.21～49.66mg/L;浮游动物4类23种,浮游动物数量为46.8～712.6ind/L,生物量为1.454～23.871mg/L;泥鳅的全长的变化范围6.2～14.3cm,体质量的变化范围为2.0～13.4g。结果说明,泥鳅全长、体质量变化与溶解氧、亚硝态氮、耗氧量、呈显著性相关(p<0.05)。
In order to study water quality and Misgurnus anguillicaudatus growth in Euryale ferox Salisb-Misgurnus anguillicaudatus co-culture ponds,hydration,plankton and growth indicators of Misgurnus anguillicaudatus were tested.The results showed that the mean value of water temperature was 26.6℃,transparency 23.2 cm,dissolved oxygen 4.8～5.6 mg/L,pH 7.6～8.3,NH_4--N 0.51～0.69 mg/L,COD 23.3～31.4 mg/L.24 species(5 phylum)of phytoplankton were observed.The abundance of phytoplankton was 6.49～13.84×10~6 ind/L,and the biomass was 17.21 ～49.66 mg/L.As for zooplankton,23 species from 4 Phyla were observed.The abundance of zooplankton ranged from 46.8 ind/L to 712.6 ind/L,and the biomass ranged from 1.454 mg/L to 23.871 mg/L.The growth rate of Misgurnusanguil licaudatusof whole length,and body weight were 6.2～14.3 cm,2.0～13.4 g respectively.The results indicated that the whole length,and body weight of Euryale ferox Salisb were significantly correlated with water dissolved oxygen,NO2-,COD.(p<0.05).
