Summary

Automatically generated

This article explains in detail a systematic approach to assess micro-mineral availability in Atlantic salmon. The methodology includes tools and models with increasing biological complexity: (1) chemical speciation analysis, (2) in vitro solubility, (3) uptake studies in cell lines, and (4) in vivo fish studies.
