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.

In fishes, the availability of taurine is regulated during ontogenetic development, where its endogenous synthesis capacity is species dependent. Thus, different pathways and involved enzymes have been described: pathway I (cysteine sulfinate-dependent pathway), cysteine dioxygenase type 1 (cdo1) and cysteine sulfinic acid decarboxylase (csad); pathway

AbstractLarval attachment organs (LAOs) are unicellular or multicellular organs that allow larvae to adhere to a substrate before yolk‐sac absorption and the free‐swimming stage. This study documents the LAO of tropical gar, Atractosteus tropicus, using a combination of scanning electron microscopy and light microscopy.

The complete mitochondrial DNA of the tropical gar ( Atractosteus tropicus )
Mitochondrial DNA Part A, 2014The mitogenome of the tropical gar, Atractosteus tropicus, (GeneBank accession number KJ531198) has a total length of 16,280 bp, and the arrangement consist of 13 protein-coding genes, 2 ribosomal RNA (rRNA) genes and 22 transfer RNA similar to other Lepisosteidae family mitogenomes.

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.

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 (

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

Tropical gar (Atractosteus tropicus) thrives in aquatic habitats with high levels of total nitrogen (TAN) and unionized ammonia (NH3). However, the tolerance of TAN and NH3, the excretion mechanisms involved, and the effects of these chemicals on routine metabolism are still unknown.

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
