The use of stable isotopes to investigate the effects of supplemental lysine and methionine on protein turnover and amino acid utilization in pacu, Piaractus mesopotamicus, juveniles
(Aquaculture, 2014-09-20) [Artigo]
The present study investigated the use of the stable isotope technique to evaluate the effects of nutritionally deficient diets, supplied or not with lysine and/or methionine, on the isotopic turnover of bio-elements (carbon ...
Natural Stable Isotopes for Determination of Gastrointestinal Transit Time in Fish
(Journal of the World Aquaculture Society, 2016-02-01) [Artigo]
This study evaluated the application of stable isotopes of carbon as an alternative and more accurate method to determine gastrointestinal transit time (GTT) in fish by comparing it to the inert marker method. The stable ...
Dietary lysine deficiency increases the incorporation rate of nitrogen-free compounds in muscle of pacu (Piaractus mesopotamicus)
(Aquaculture, 2017-10-01) [Artigo]
Isotopic experiments are conducted to evaluate turnover rates in fish tissue, especially as a function of nutrition. In 2007, Cerling et al. proposed an approach they named the reaction progress variable, which among other ...
