[Histology of reproductive cycle of tropical gar Atractosteus tropicus females (Lepisosteiformes: Lepisosteidae) in Tabasco, Mexico].

open access: yesRevista de biologia tropical, 2013
In Southeast Mexico, A. tropicus is a species with great ecological, economic, cultural and aquaculture value, however wild populations have diminished due to diverse anthropological causes. The objective of this study was to characterize the reproductive cycle of A.

The hepatopancreas microbiome of velvet crab, Necora puber. [PDF]

open access: yesEnviron Microbiol Rep
We provide the first description of the hepatopancreas microbiome of the velvet crab, Necora puber, identifying a microbial community dominated by Candidatus hepatoplasma and the presence of a core microbiome. We also investigate the variation explained by our study factors: crab sex, parasite infection status, and two different sampling time points ...

Changes in Digestive Enzyme Activities during Larval Development of Spotted Seatrout (Cynoscion nebulosus). [PDF]

open access: yesAquac Nutr
The spotted seatrout (Cynoscion nebulosus)—an important commercial species—has a high potential for aquaculture in the Gulf of Mexico. To optimize its feeding during larval rearing, this study aims to evaluate the primary gastric (pepsin), intestinal (leucine aminopeptidase and alkaline phosphatase), and pancreatic (alkaline protease, trypsin ...

Cardiorespiratory physiological phenotypic plasticity in developing air-breathing anabantid fishes (Betta splendens and Trichopodus trichopterus). [PDF]

open access: yesPhysiol Rep, 2017
Developmental plasticity of cardiorespiratory physiology was determined in two air‐breathing anabantid fishes (Betta splendens and Trichopodus trichopterus) by chronic rearing in nocturnal hypoxia. Hypoxic rearing increased hypoxic tolerance in Betta, which inhabits temporary ponds with nocturnal hypoxia.

The larval attachment organ of the bowfin Amia ocellicauda Richardson, 1836 (Amiiformes: Amiidae) and its phylogenetic significance

open access: yesJournal of Fish Biology, Volume 103, Issue 6, Page 1300-1311, December 2023., 2023
Abstract Larval attachment organs (LAOs) are unicellular or multicellular organs that enable the larvae of many actinopterygian fishes to adhere to a substrate before yolk‐sac absorption and the free‐swimming stage. Bowfins (Amiiformes) exhibit a sizable LAO on the snout, which was first described in the late 19th and early 20th centuries.

Gut Microbiome Analysis In Adult Tropical Gars ( Atractosteus tropicus ) [PDF]

open access: yes, 2019
Abstract Tropical gar ( Atractosteus tropicus ), is freshwater and estuarine fish that has inhabited the Earth since the Mesozoic era, undergoing limited physiological variation ever since. This omnivorous fish is endemic to southern Mexico and part of Central America.

Cross amplification of microsatellite loci developed for Atractosteus spatula in Atractosteus tropicus

open access: yesRevista Mexicana de Biodiversidad, 2013
AbstractDue to recent population declines in tropical gar (Atractosteus tropicus), a greater understanding of its population structure is needed. A key step in gaining this understanding is the development of microsatellite loci for use in this species. For this purpose, 33 microsatellite loci from alligator gar (A.

Developmental cardiorespiratory physiology of the air-breathing tropical gar,Atractosteus tropicus [PDF]

open access: yesAmerican Journal of Physiology-Regulatory, Integrative and Comparative Physiology, 2016
The physiological transition to aerial breathing in larval air-breathing fishes is poorly understood. We investigated gill ventilation frequency ( fG), heart rate ( fH), and air breathing frequency ( fAB) as a function of development, activity, hypoxia, and temperature in embryos/larvae from day (D) 2.5 to D30 posthatch of the tropical gar ...
