Trans-intestinal absorption rates differ between free amino acids during larval development in Atlantic herring (Clupea harengus)

This paper provides important and quantitative information to understand uptake of different classes of dietary free amino acids in larval stages of fish. We use herring as model since it gives the best combination of size, transparency, robustness, gut morphology for in vivo tube feeding. The data is relevant for formulation of starter diets.
