中文摘要:
      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鱼摄食的外在因素,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。同时,需加强鳜摄食调控机制及营养生理需求特性的研究,实现鳜鱼配合饲料的突破,促进其养殖业的绿色健康发展。
英文摘要:
      Mandarin fish (Siniperca sp.) is a valuable freshwater economic fish in China, and its production has been approached 330,000 tons in 2019. The test introduced aquaculture situation of this fish from aspects of aquaculture status, aquaculture mode and selective breeding. The feeding habit of this fish is unique, which relies on prey fish for all lifetime. For many years, prey fish are mainly used to feed mandarin fish, 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 manuscript also summarized the external factors affecting feeding characteristics of this fish 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 this fish through artificial intervention, and provide necessary basis for its conversion to eat formula feed. Meanwhile, 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.
