Description

Shrimp family culture test system Technical Field The invention relates to a test system for the family culture of prawns. Background In the cultivation process of marine organisms, the growth characters are directly related to cultivation period and yield, and the varieties with rapid growth and strong disease resistance can be marketed in a shorter time, so that the cultivation efficiency is improved, and the cultivation cost is reduced. Therefore, the excellent variety is important to the economic benefit of seawater and aquatic products. For breeding work, it is desirable to select superior parents for propagation and breeding, so that offspring with superior traits are desired. Therefore, it is also important for the cultivation of parents.
