The present study aims to determine the best technique of Guanidinoacetic acid (GAA) supplementation improve retention added GAA after immersion in water on growth performance Pangasius catfish (Pangasius hypophthalmus). juveniles with a mean body weight and length 16.05 ± 0.47 g 12.42 0.30 cm were randomly distributed into 9 pond units (2 x 1 0,6 m). Three experimental diets formulated contain...

the molecular phylogenetic trees of 42 representative samples of malaysian pangasiid were constructed using cytochrome c oxidase subunit i (coi). the topologies resulting from molecular analyses, maximum parsimony, maximum likelihood, and bayesian inference, revealed the paraphyly of pangasius genus and monophyly of p. nasutus, p. bocourti, p. micronemus, and p. hypopthalmus with high support v...

Cathepsin inhibitor has been purified to homogeneity from catfish muscle (Pangasius sp.). The purification was carried out through ammonium sulphate precipitation, followed by ion exchange chromatography using DEAE-Sephadex A-75, followed by gel filtration on Sephadex G-100. Throughout the purification procedure, cathepsin inhibitory activity was determined against hemoglobin. A single band of ...
