Expression of ion transport proteins and routine metabolism in juveniles of tropical gar (Atractosteus tropicus) exposed to ammonia

Comparative Biochemistry and Physiology Part C: Toxicology & Pharmacology, 2021
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.

The larval attachment organ of the tropical gar Atractosteus tropicus Gill, 1863 (Lepisosteiformes: Lepisosteidae)

Journal of Fish Biology, 2021
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.

Gonadotropin-inhibitory hormone (GnIH) distribution in the brain of the ancient fish Atractosteus tropicus (Holostei, Lepisosteiformes)

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).

Alimentos microencapsulados para el cultivo de larvas de pejelagarto (Atractosteus tropicus)

2018
Abstract Tropical gar is an important species for aquaculture purposes in Southeast Mexico. Several studies regarding nutrition and digestive physiology have been done; however, the use of microcapsules for larvae feeding to improve growth and survival has not been conducted.
