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

General and Comparative Endocrinology, 2020 The Holostei group occupies a critical phylogenetic position as the sister group of the Teleostei. However, little is known about holostean pituitary anatomy or brain distribution of important reproductive neuropeptides, such as the gonadotropin-inhibitory hormone (GnIH).

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,

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.

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.

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.

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.

Aquatic hypoxia is both a naturally-occurring and anthropogenically-generated event. Fish species have evolved different adaptations to cope with hypoxic environments, including gill modifications and air breathing. However, little is known about the molecular mechanisms involved in the respiration of embryonic and larval fishes during critical windows
