Hippocampus erectus, which is named as "south ginseng" in China, is the main breed of domestic breeding and it is a precious marine animal with scarce medicinal resources, The sharp contradiction between market supply and demand leads to the shortage of wild resources of H. erectus, and the core problem of artificial cultivation is the low survival rate in seedling stage. In this experiment, the feeding behavior of juvenile at the age of 1-30 days (body height: 9.22~43.16mm) was observed and recorded through behavioral research, the feeding ability and the allometric development at the juvenile stage were studied by analyzing feeding behavior parameters. Finally, the degree of consummation of feeding function was discussed by combining the development of muzzle bone, vision and digestive system. |
