不同混养模式下中华鲟养殖池透明度变化及其影响因素
Transparency variation and its influencing factors between different polyculture models with Anodonta woodiana and Hypophthalmichthys molitrix, Aristichthys nobilis in Chinese sturgeon Acipenser sinensis culture pond
摘要
Abstract
The results of a transparency ( SD) contrast test between different Chinese sturgeon polyculture models with freshwater mussel Anodonta woodiana and silver carp Hypophthalmichthys molitrix, bighead carp Aristichthys nobilis indicated that the average transparencies were 11.92, 16.45 , 17.45 cm which increased by 26. 69% , 56. 67% , 66.19% compared with background value before the test for pond 1 (control group) , pond 2(A.woodiana-polyculture group) , pond 3 (H. molitrix, A. noilis-polyculture group) , respectively. The overall transparency level of pond 2 and 3 were significantly higher than that of pond 1, highest reached to twice. The panel data models of three ponds' transparency and other water quality parameters were: SD1 = -0. 0072 TSS + 0.8353 NH4+ -N - 2.1711 TN + 0. 6195 TP - 0. 0405 COD + 16. 7815, SD2 = 0. 0030 TSS + 3. 8864 NH4+ -N + 0. 1893 TN -12.4585 TP***-0.0104 COD+24.5306, SD3 =0.0381 TSS* +3.7821 NH4+-N+0. 6003 TN - 15.0444 TP*** -0.4078 COD** +34.2992. Total phosphorus (TP) was the main index, with ammonia nitrogen (NH4+-N) , total nitrogen (TN) , chemi-cal oxygen demand (COD) as indirect ones, TSS as direct one, influencing the transparency of Chinese sturgeon culture pond.Polyculture with H. molitrix and A. nobilis excels the treatment hanging A. woodiana in transparency rise effects in the Chinese sturgeon culture pond with muddy water and high concentration of total suspended solids.关键词
