The pursuit of enhanced muscle quality in farmed fish is a continuous effort for the aquaculture industry, directly impacting market value and consumer satisfaction. Scientific research has increasingly highlighted the role of specific amino acids in achieving these goals, with L-Hydroxyproline (Hyp) emerging as a compound of significant interest for its multifaceted effects on muscle development and composition.

Studies examining the dietary supplementation of L-Hydroxyproline in fish species, such as the triploid crucian carp (Carassius auratus Triploid), reveal a compelling link between Hyp intake and improved muscle characteristics. Research indicates that adequate dietary levels of Hyp can lead to enhanced collagen synthesis, a critical factor for muscle texture, firmness, and structural integrity. Specifically, increased levels of Type I Collagen (Col I) and Pyridinium crosslink (PYD) in fish muscle have been observed with higher Hyp supplementation, suggesting a direct influence on collagen cross-linking and overall tissue strength.

Beyond biochemical markers, L-Hydroxyproline appears to influence muscle growth at a molecular level. Investigations into gene expression have shown that dietary Hyp can upregulate genes involved in both collagen synthesis (e.g., col1a1, col1a2, p4hα1, p4hβ) and muscle development (e.g., igf-1, tor, myod, myf5, myhc). This suggests that Hyp not only provides a building block for collagen but also actively participates in the signaling pathways that regulate muscle fiber growth and differentiation.

The practical implications for aquaculture feed formulators are substantial. By incorporating L-Hydroxyproline into feed formulations, especially those relying on plant-based proteins where Hyp can be deficient, producers can optimize fish growth performance and significantly improve muscle quality. This can translate to increased marketability and a competitive advantage.
