- •
Fish muscle half-life values for carbon and nitrogen differed according to salinity.
- •
Turnover rates for carbon and nitrogen were considerably slower in freshwater.
- •
Carbon isotopic turnover in muscle was mainly driven by catabolism.
- •
Trophic discrimination factors were higher in saltwater for both carbon and nitrogen.
