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 ...

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

Latin American Journal of Aquatic Research, 2019 Tropical gar ( Atractosteus tropicus ) aquaculture is a potential economic activity in southeast Mexico. This study analyzed the economic profitability of tropical gar grow-out using two commercial feeds (Silver Cup ® and Super ® ). The last one was designed based on the digestive physiology of the species. The experiment was conducted in six concrete
