Abstract

The invention relates to a method for cultivating large yellow croaker fingerling and a screening molecular marker applied to the method. The method comprises the following steps: 1) screening the related genes of growth axis of the large yellow croaker and the chain SSR thereof; 2) compounding a primer; 3) detecting SSR primer extension polymorphism; 4) marking and screening the growth related SSR; 5) marking and screening parent fish of large yellow croaker; 6) cultivating the large yellow croaker fingerling. The method can overcome the defects being short of rapid screening and cultivation for the large yellow croaker fingerling of the prior art and has the advantages of high speed, convenience, effectiveness and capability of accelerating the cultivating process of large yellow croaker.

Description

technical field [0001] The invention relates to a method for cultivating large yellow croaker fry and a screening molecular marker used therein, which are applied to cultivating high-quality large yellow croaker varieties with fast production. Background technique [0002] Large yellow croaker (Larimichthys crocea) is a unique seawater economic fish in my country. It is known as the "national fish". And 33.15% and 10.75% of the aquaculture output, with an annual output value of more than 10 billion yuan. It is the largest marine aquaculture fish in my country and one of the eight advantageous export aquaculture aquatic products. However, due to the lack of scientific and effective management measures in the long-term extensive breeding process, the germplasm of large yellow croaker is facing many problems such as slow growth, premature sexual maturity, individual miniaturization and decline in disease resistance, and germplasm improvement is urgently needed , in order to bre...
