2.2.2 春季培育。春季培育是指亲体性腺开始发育阶段,这一阶段亲体性腺发育特征是生殖细胞从Ⅱ期向第Ⅲ期转化的重要发育时期。此阶段亲体培育主要目的是促进亲体性腺发育。使亲体性腺早日转化到第Ⅲ期;其次则是投喂优质饲料,以满足亲体性腺发育所需营养物质。春季培育主要工作是调控水温、投饵、调节光照、调节水质。调控水温是指春季因水温较低,不利于亲体性腺,所以用升温的方法将水
2.2.2 spring training. Spring cultivation refers to the beginning of the developmental stage of the gonadal gonad, and the developmental characteristics of the gonadal gonads at this stage are the important developmental stages of the germ cell transformation from stage II to stage III. The main purpose of this phase parental development is to promote parental gonadal development. So that the early conversion of the parental gonads to stage Ⅲ; followed by the feeding of high-quality feed to meet the needs of the development of the parental gonadal nutrients. Spring cultivation is the main job of regulating water temperature, feeding, regulation of light, regulate water quality. Regulation of water temperature is due to lower water temperature in spring is not conducive to the parental gonads, so the method of warming the water
