摘要:

本研究旨在优化宽体金线蛭(Whitmania pigra)规模化养殖关键技术,明确关键水环境因子的适宜阈值及其对宽体金线蛭生长与存活的影响,构建集约化的健康养殖模式。采用梯度试验方法,测定了水温、溶解氧(DO)含量、酸碱度(pH值)等理化参数的适宜范围,同时应用水体微生物16S rRNA测序技术,系统分析了养殖水体的微生物群落组成与分布,并评估其对宽体金线蛭成活率的影响。结果表明,宽体金线蛭的最佳养殖条件为水温25.1~28.0 ℃、DO含量≥5.1 mg·L-1、pH值6.6~7.5,在该条件下其10 d成活率可达90%以上。在此基础上,本研究进一步集成了孵化基质优化、生态循环水养殖、病害防控及多样化养殖模式等关键技术,形成了一套高效的宽体金线蛭健康养殖技术体系。该研究结果可为宽体金线蛭养殖产业的标准化与可持续发展提供技术依据。

Abstract:

This study aimed to optimize the key technologies for large-scale breeding of Whitmania pigra,clarify the appropriate threshold values of key water environmental factors and their effects on the growth and survival of W. pigra,and construct an intensive and healthy breeding model. Using gradient experiments,the suitable ranges for physicochemical parameters such as water temperature,dissolved oxygen(DO) content,pH value were determined. Additionally,16S rRNA sequencing was applied to monitor the composition and distribution of aquatic microorganisms. These parameters were comprehensively analyzed and evaluated for their effect on the survival rate of W. pigra. The results showed that the optimal breeding conditions were 25.1-28.0 °C,DO content≥5.1 mg·L-1,and pH value 6.6-7.5,under which the 10-day survival rate was over 90%. Based on these findings,this study further integrated key technologies such as optimized hatching substrates,ecological recirculating water breeding,disease prevention and control,and diversified breeding models,forming an efficient and healthy breeding technology system for W. pigra. The findings provide technical support for the standardization and sustainable development of W. pigra breeding industry.
