Determination of optimal prey for rearing tropical gar Atractosteus tropicus (Lepisosteiformes: Lepisosteidae) [PDF]

Revista de Biología Tropical, 2018
Larval feeding studies of both ornamental and consumable fish species are important for formulating successful management, and culture strategies for conservation purposes. In the present study, we evaluated prey selectivity for the tropical gar Atractosteus tropicus in the larval stage (first 8 weeks) using the zooplankton Artemia fransiscana, Daphnia

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

Revista 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.

Fructooligosaccharide supplementation in diets for tropical gar ( Atractosteus tropicus ) juvenile: Effects on morphophysiology and intestinal barrier function

Aquaculture Research, 2020
Supplementary fructooligosaccharides (FOS) were evaluated on growth, survival, gut morphology, digestive enzyme activity and expression of intestinal barrier genes in tropical gar (Atractosteus tropicus). Four treatments were designed to include FOS (5, 10, 15 and 20 g/Kg) and were compared with a control (0 g/Kg) and the current commercial trout diet.

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

Journal 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.

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

American 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 ...

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

, 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.
