欧洲丁桂鱼的鱼苗鱼种培育是指将刚孵化出膜的仔幼鱼培育成供放养的较大规格的鱼苗、鱼种的过程。各地对鱼苗鱼种定义的大小不尽相同。一般来说,鱼苗培育一般是指5cm以前的丁桂鱼的培育过程,鱼种培育则是指将5cm以前的丁桂鱼培育至5～8cm或8～16cm的鱼的过程。因养殖方法、鱼苗体质、管理水平不同鱼苗培育又分为乌仔阶段的培育,寸片阶段的培育。鱼种培育可以分为小规格鱼种的培育,大规格鱼种的培育。丁桂鱼成鱼的适应性很强,但在其早期的苗种阶段,尤其是鱼苗阶段,身体幼小纤弱,摄食能力低,饵料范围窄,且易受外界环境条件变化的影响,对敌害和病原体的抵抗应付能力低,在管理不当的情况下,死亡率高。因此必须对丁桂鱼的苗种培育引起足够的重视,要求在人工严密控制的条件下,给予精心的饲养管理,从而提高鱼苗、鱼种的存活率,培育出健壮、合乎生产规格的优质鱼种。
European Ding Gui fish fry breeding refers to the hatch out of the juvenile larvae into a larger size for the stocking of fry, fish species process. The size of fish and fish species is not the same across the world. In general, fry breeding generally refers to 5cm before the cultivation of Ding Gui fish, fish cultivation refers to the 5cm before Ding Gui fish breeding to 5 ~ 8cm or 8 ~ 16cm fish process. Due to farming methods, fry physical, different levels of management of fry breeding is divided into Wu Zi stages of cultivation, inch film stage of cultivation. Fish breeding can be divided into small-scale cultivation of fish species, large-scale cultivation of fish species. Dinggui adult fish adaptability, but in its early seed stage, especially the fry stage, the body is young and delicate, low feeding capacity, narrow range of food, and vulnerable to changes in the external environment, the impact of the enemy Low resistance to pathogens and coping skills, and high mortality in poorly managed conditions. Therefore, it is necessary to give sufficient attention to the cultivation of Ding Gui fish, and require careful rearing and management under the conditions of artificial control so as to improve the survival rate of fry and fish species and to cultivate the quality and quality fish that meet the production specifications Species.
