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.

Fishes, 2022 This study was conducted to investigate the effects of dietary fructooligosaccharides (FOS) on the growth, survival rate, digestive enzyms activity, and the expression of intestinal barrier function genes in tropical gar (Atractosteus tropicus) larvae. A

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.

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 ...

Fishes, 2022 In ectotherm species, environmental temperature plays a key role in development, growth, and survival. Thus, determining how temperature affects fish populations is of utmost importance to accurately predict the risk of climate change over fisheries and ...

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.
