在家鱼人工繁殖过程中,性腺的发育成熟是保证生产的先决条件。因此,如何促进亲鱼的性腺发育是生产上的关键问题之一,这在我国北方较冷地区尤为重要。近年来在生产实践中已创造出一些优良的养殖经验,但是由于鱼卵的构造比较复杂,卵巢发育中的代谢过程也极为繁复,因而,对于这些实际经验还不易从理论上加以阐述,这就影响了生产技术的继续提高和发展。为了解决这个问题,必须对鱼体性腺的发育过程及其变化机制进行研究,才能对亲鱼培育的技术措施,提供理论上的依据和改进的建议。本文拟先就白鲢的卵巢发育过程
Artificial reproduction in the process of domestic fish, gonadal maturity is to ensure that the prerequisite for production. Therefore, how to promote gonadal development of broodstock is one of the key problems in production, which is especially important in the colder areas of northern China. In recent years, some good breeding experiences have been created in the production practice. However, due to the complex structure of fish eggs and the complicated metabolic process in ovary development, it is not easy to theoretically elaborate on these practical experiences Affected the continuous improvement and development of production technology. In order to solve this problem, it is necessary to study the developmental process of gonadal development and its mechanism of change in order to provide theoretical basis and suggestions for improving the technical measures of broodstock breeding. This paper first proposed the silver carp ovary development
