中文摘要:
      随着人口与经济的发展,水产养殖业在世界范围内迅速兴起,集约型工厂化循环水养殖因其高密度、低污染、高效率等独特的优势,契合水产养殖业绿色发展理念,已成为水产养殖转型升级的重要方向之一。水作为循环水养殖系统中最主要的环境因子之一,其流态能够直接影响鱼类的生长及福利,同样鱼类存在及运动也影响到系统流态的构建。本文综合分析了循环水养殖系统中流场条件对不同鱼类生长发育及福利的影响,鱼类及其运动行为对养殖池内水动力条件及性能的影响,以及鱼类对养殖池内流场流态、溶解氧等的影响。将研究鱼类运动对流场特性的影响方法主要归纳为实测法和数值研究,通过对比分析两种方法的优点和不足之处,并结合当前循环水养殖产业系统构建中的问题提出针对性方法建议,旨在为系统中水动力条件的设计提供新思路,促进循环水养殖产业流态构建向“鱼”与“水”兼顾方向发展。
英文摘要:
      With the development of population and economy, aquaculture is rapidly emerging in the world. Factory recirculating aquaculture has become one of the important directions of aquaculture transformation and upgrading because of its unique advantages such as high density, low pollution and high efficiency, which fits the concept of green development of aquaculture. As one of the most important environmental factors in the recirculating water aquaculture system, the flow pattern can directly affect the growth and welfare of fish, and the presence and movement of fish also affect the construction of the system flow pattern. This paper presents a comprehensive analysis of the effects of flow field conditions on the growth and welfare of different fish species in a recirculating aquaculture system, the effects of fish and their locomotor behavior on the hydrodynamic conditions in the culture pond, and the effects of fish on the flow pattern and dissolved oxygen in the culture pond. The main methods of studying the influence of fish movement on the flow field characteristics are summarized as the actual measurement method and the numerical study, and the advantages and shortcomings of the two methods are compared and analyzed. The aim is to provide new ideas for the design of hydrodynamic conditions in the system, and to promote the development of the circulating water aquaculture industry in the direction of "fish" and "water".
