Development and assessment of novel endogenous markers in commercial aquafeeds to measure apparent digestibility in large Atlantic salmon ( Salmo salar ) on salmon farms
As salmon aquaculture continues to grow, understanding aquafeed conversion is imperative for making informed strategic growth planning and management decisions. Accurately measuring the apparent digestibility (AD) of commercial aquafeeds on farms requires greater understanding and method development...

As salmon aquaculture continues to grow, understanding aquafeed conversion is imperative for making informed strategic growth planning and management decisions.
