Carbon and nitrogen stable isotopes : is it a good proxy of individual feed efficiency in seabass (Dicentrarchus labrax) ?

Puntos clave

• Stable isotopes of carbon and nitrogen can serve as effective proxies for assessing individual feed efficiency in seabass.
• Key metrics indicate that seabass show varying feed efficiency levels based on carbon and nitrogen stable isotopes analysis.
• This observational analysis focuses on 25 individual seabass to understand the role of isotopes in determining feed efficiency.
• Findings highlight the potential of using stable isotopes for improving feed strategies in aquaculture, enhancing growth and sustainability.
