Empowerment of Rural Communities in Tabasco Producing Tropical Gar (Atractosteus tropicus): Technology Transfer and Training

Introducción La transformación sustentable de los recursos naturales locales en productos con valor agregado se ha consolidado como una de las rutas más prometedoras para fortalecer las economías rurales del sureste mexicano. En Tabasco, las comunidades pesqueras han dependido históricamente de la captura estacional de especies nativas ...

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.

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

, 2019
AbstractTropical 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

Revista 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.

Inclusion of Mannan-Oligosaccharides in Diets for Tropical Gar Atractosteus tropicus Larvae: Effects on Growth, Digestive Enzymes, and Expression of Intestinal Barrier Genes

Fishes, 2022
Mannan-oligosaccharides (MOS) are non-digestible carbohydrates, and their use in aquaculture as prebiotics is well documented. The objective of this work was to test whether MOS supplemented in the diet of A.

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

, 1990
Articulo CientificoDevelopmental plasticity of cardiorespiratory physiology in response to chronic hypoxia is poorly understood in larval fishes, especially larval airbreathing fishes, which eventually in their development can at least partially “escape ...

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

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
