两种循环水养殖模式的凡纳滨对虾生长和水质比较研究
Study on growth and water quality comparison of Litopenaeus vannamei in two circulating aquaculture models
摘要
Abstract
This study aimed to investigate the growth differences and aquaculture water quality changes of Litopenaeus vannamei in modern industrialized recirculating aquaculture systems under outdoor and indoor conditions.This study set up two models of aquaculture:outdoor pond greenhouse recirculating aquaculture and indoor factory recirculating aquaculture.Under the same initial stocking size,stocking density,and culture duration,the growth patterns and water quality variations of Litopenaeus vannamei were investigated.The results showed that Litopenaeus vannamei exhibited rapid growth in both modes,with specific growth rates(SGR)of body mass exceeding 1.62%.The outdoor mode demonstrated faster growth,achieving an SGR of 2.05%.The harvest sizes were(9.50±0.81)cm and(11.03±2.60)g for the indoors mode,and(10.17±0.76)cm and(12.98±2.27)g for the outdoors mode,with survival rates exceeding 80.9% in both modes.A strong power-function relationship(W=aLb)was observed between body length and mass in both modes,with equations of W=0.009 6 L3.075 8(R2=0.915,P<0.01)for the outdoor mode and W=0.014 L2.915 3(R2=0.860 4,P<0.01)for the indoor mode.The b-values were closed to 3,indicating isometric growth between body length and mass.Additionally,quadratic relationships were found between body length,body mass,and culture time(Outdoor breeding mode L=-0.000 8 t2+0.080 7 t+8.478,R2=0.980 7,P<0.01;Indoor breeding mode L=0.001 t2+5×10-5 t+8.517 3,R2=0.957 6,P<0.01;Outdoor breeding mode W=-0.007 1 t2+0.439 9 t+6.056 3,R2=0.909,P<0.01;Indoor breeding mode W=-0.000 7 t2+0.173 8 t+6.149,R2=0.997 3,P<0.01).Significant differences were observed in water quality indicators(TAN,NO-2-N,NO-3-N,CODMn,TN,and TP)between the two modes.The outdoor mode exhibited significantly lower TN and TP concentrations compared to the indoor mode,along with lower NO-3-N concentrations in the late culture stage.However,NO-2-N concentrations were higher in the early to mid-culture stages outdoors.No significant regular patterns were observed for TAN and CODMn concentrations,although both decreased in the late culture stage.Research indicated that Litopenaeus vannamei grows faster and the water quality was better in outdoor pond greenhouse recirculating aquaculture compared indoor factory-based recirculating aquaculture systems,making it suitable for breeding promotion.The research provided a paradigm for the exploration of modern facility-based breeding patterns and intelligent management of Litopenaeus vannamei.关键词
