Abstract
This study aims to standardize absorptiometry technique by dual-energy x-ray absorptiometry (DXA) and to apply it to model the main chemical constituents of fish during the development stages. The first study will be conducted to obtain the standard equation of the matching of the values estimated by DXA for pacu (Piaractus mesopotamicus) and tilapia (Oreochromis niloticus). The chemical …
