鳜养殖概况及摄食调控机制研究进展

Research progress on aquaculture and feeding regulation mechanism of Mandarin fish

  • 摘要: 鳜是我国名贵的淡水经济鱼类,2019年其养殖产量已达33万t。本文从养殖现状、养殖模式及良种选育等方面介绍鳜的养殖概况。同时,鳜摄食习性独特,终生以活鱼为食。养殖生产中,主要以活饵料鱼直接饲喂,这种以鱼养鱼的方式不仅资源利用率低,对环境和资源的破坏也极大。据此,本文从环境因素和饵料性质等方面概述了影响鳜摄食的外在因素,并从摄食感觉器官和摄食调控因子剖析鳜摄食特性的内在因素,这有助于通过人工干预的方式调整鳜的摄食习性,为其转食配合饲料提供必要的支撑。此外,需加强鳜摄食调控机制及营养生理需求特性的研究,实现鳜配合饲料的突破,促进其养殖业的绿色健康发展。

     

    Abstract: Mandarin fish (Siniperca sp.) is a valuable freshwater economic fish in China, and its production has approached 330000 tons in 2019. This paper introduced aquaculture situation of Siniperca sp. from three aspects, including aquaculture status, aquaculture mode and selective breeding. The feeding habit of Siniperca sp. is unique, which relies on prey fish for lifetime. For many years, prey fish are mainly used to feed Siniperca sp., and the way of raising fish by fish not only causes the waste of fishery resources, but also aggravates the damage to environment and resources. Thus, the paper also summarized the external factors affecting feeding characteristics of Siniperca sp. species from environmental factors and feed properties, and analyzed the internal factors from the aspects of feeding sense organs and feeding regulation factors. This may be helpful to adjust the feeding habits of Siniperca sp. through artificial intervention, and provide necessary basis for its conversion to eat formula feed. Additionally, it is necessary to strengthen the research on the feeding regulation mechanism and nutritional physiological demand characteristics, so as to achieve the breakthrough of compound feed and promote the green and healthy development of its aquaculture industry.
