Trypsin gene expression in adults and larvae of tropical gar Atractosteus tropicus
Fish Physiology and Biochemistry, 2019Trypsin 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

Digestive enzymatic activity on Tropical gar (Atractosteus tropicus) larvae fed different diets
Fish Physiology and Biochemistry, 2011Digestive 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.

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 ...

HELMINTH PARASITES OF THE TROPICAL GAR, ATRACTOSTEUS TROPICUS GILL, FROM TABASCO, MEXICO
Journal of Parasitology, 2004A total of 8 helminth species were recorded in an examination of 43 tropical gar, Atractosteus tropicus Gill, collected at the Pantanos de Centla Biosphere Reserve, Tabasco, Mexico. The parasite species included 1 adult trematode, 3 metacercariae, 1 cestode, 1 adult nematode, and 2 nematode larvae. Six of these 8 species were rare, with low prevalence (

Using cornstarch in microparticulate diets for larvicultured tropical gar (Atractosteus tropicus)
Fish Physiology and Biochemistry, 2015Aquaculture in Mexico has been developed by the cultivation of commercial species. In Tabasco, the cultivation of native species is mainly limited by the lack of nutrition studies to support its crop profitability. Among these species is the tropical gar (Atractosteus tropicus), which has great potential for cultivation.

Fish development can be affected by environmental pollutants such as crude oil (anthropogenic or natural sources), causing alterations especially in cardiac function and morphology. Most such studies have focused on saltwater species, whereas studies in freshwater fishes are scant. The objective of the current study was to evaluate the effects of crude

Estado de arte de la biología y cultivo de pejelagarto (atractosteus tropicus) [PDF]
Native fresh water fish are an important source of food and protein for human society. A full study of the native aquatic species and the development of technologies that allow the controlled production of these fish in a profitable, innocuous and environment-friendly manner, are some of the big challenges for aquaculture in this millennium. Therefore,

Partial characterization of digestive proteases in tropical gar Atractosteus tropicus juveniles
Fish Physiology and Biochemistry, 2013Tropical 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.
