Partial characterization of digestive proteases in tropical gar Atractosteus tropicus juveniles

Fish Physiology and Biochemistry, 2013
Tropical gar (Atractosteus tropicus) is an economically and socially important freshwater species from Southeastern Mexico, with a high aquaculture potential. With this in mind, the purpose of this study was to characterize the digestive proteases of tropical gar juveniles through biochemical and electrophoretic analyses.

Digestive enzymatic activity on Tropical gar (Atractosteus tropicus) larvae fed different diets

Fish Physiology and Biochemistry, 2011
Digestive enzymatic activity and growth performance on tropical gar (Atractosteus tropicus) larvae fed Artemia nauplii (LF), frozen adult Artemia (AB), an artificial diet (AF) with 46% protein and 16% lipids and a starvation group (SG) from first feeding (5 days after hatching-5 DAH) to 34 DAH were studied.

Trypsin gene expression in adults and larvae of tropical gar Atractosteus tropicus

Fish Physiology and Biochemistry, 2019
Trypsin gene (try) expression levels were quantified in different organs of wild and captive tropical gar (Atractosteus tropicus) adults, and changes in expression during initial ontogeny of the species were determined. RNA was extracted from the pancreas, and cDNA was synthesized and later amplified by endpoint PCR using oligonucleotides designed from

Development of digestive tract and enzyme activities during the early ontogeny of the tropical gar Atractosteus tropicus

Fish Physiology and Biochemistry, 2015
Changes in digestive enzyme activity and histology were studied in Atractosteus tropicus embryos, larvae and juvenile periods. Alkaline protease, chymotrypsin, carboxypeptidase A, lipase and α-amylase were detected in all periods and gradually increased until reaching the maximum peak in juveniles; meanwhile, acid protease was first detected at 5 days ...
