Overview

Observational analysis showed improved muscle composition and lipid metabolism in red claw crayfish, suggesting dietary supplementation is beneficial.

Key Points

  • Dietary supplementation with rhodotorula mucilaginosa enhanced muscle crude protein and antioxidant capacity in red claw crayfish, indicating health benefits.
  • Compared to the control, treatment groups experienced higher levels of essential amino acids and lower saturated fatty acids, signaling improved nutritional quality.
  • The analysis demonstrated significant changes in biochemical indicators, including enzymes and proteins correlated with health and metabolism after supplementation.
  • Supplementation was found to regulate mTOR signaling and lipid metabolism genes, highlighting the potential for using rhodotorula mucilaginosa in aquaculture nutrition.
