RFE PAGE 3 taxonomic identification tools: Multiple Feature Morphological / Coloration Table for Cod Family (Gadid) Species
--Constructed for FDA Regulatory Fish Encyclopedia from the Available Ichthyological Literature.

This Multiple Feature Table is a multivariable approach to the appearance in Cod family species of a set of characteristic features that Cod family species largely share, yet may vary between species within the family. The variance is used to establish a set of morphological and color features indicative for each species. This page is under construction.
