Compensatory growth (CG) in fish is heavily influenced by nutrient metabolism. However, there are limited studies examining how nutrient metabolism is regulated during this process. For silver pomfret, an important commercial marine fish, it's crucial to establish effective starvation and re-feeding strategies to ensure good water quality and fast growth. To identify the complete compensatory growth model of silver pomfret, we conducted an experiment with a control group (normal feeding) and three starvation/re-feeding groups. We observed that the recovery of weight and condition factor in the 14-day starvation and 14-day re-feeding groups was significantly faster than other groups, indicating full compensatory growth. Thus, we selected this group for the next experiment. We performed untargeted metabolomics and transcriptome analysis of muscle tissue on Day 14, 21 and 28 (CG process), and examined the key regulatory genes of nutrient metabolism on Day 0, 7, 14, 21 and 28 (starvation and re-feeding process)....
