Germplasm innovation of large yellow croaker and its research progress

Large yellow croaker is one of the species with the highest production of marine fish culture in China. Germplasm resources are the indispensable material basis for the healthy and sustainable development of large yellow croaker aquaculture industry. It is of great significance to systematically carry out the collection and preservation, identification and evaluation, and germplasm innovation of large yellow croaker germplasm resources. This paper summarizes the progress in the conservation and exploitation of large yellow croaker germplasm resources and germplasm innovation. Around the main line of conservation of large yellow croaker germplasm resources and the creation of good varieties, the development direction of creating major new varieties for complex economic traits (e.g., disease resistance, stress resistance, quality, and feed utilization efficiency, etc.) was proposed, which provided theoretical support for realizing the significant improvement of the coverage rate of improved varieties of large yellow croaker and the healthy development of large yellow croaker industry.
