Abstract:
In order to study the molecular mechanism of muscle development of juvenile
Elopichthys bambusa, the characteristics of muscle development of juvenile
Elopichthys bambusa under different developmental stages and domestication strategies were discussed by histological and transcriptome analysis and fluorescence quantitative PCR verification. The results showed that the mosaic proliferation of muscle fibers of
Elopichthys bambusa larvae began on the 22nd day post-hatching (dph). During the early stage of muscle mosaic proliferation, genes related to MyoGenic regulators (
myog and
myod), the myostatin gene (
mstn), muscle satellite cell marker gene (
pax7), and muscle differentiation-related genes (
myl3,
tnni2,
myoz2,
tpm1) were actively involved. In addition, the use of artificial compound feed can improve muscle metabolism and promote growth in juvenile
Elopichthys bambusa, with the 22 dph group showing higher weaning efficiency and better weaning effect. This study provide a foundation for understanding the characteristics and molecular mechanism of muscle development in
Elopichthys bambusa and provide a theoretical reference for large-scale farming practices.
