High-throughput sequencing of the 16S rRNA gene to analyze the gut microbiome in juvenile and adult tropical gar (Atractosteus tropicus) [PDF]

open access: yesLatin American Journal of Aquatic Research, 2020
Tropical gar (Atractosteus tropicus) is freshwater and estuarine fish, inhabiting the Earth since the Mesozoic era and undergoing limited physiological variation ever since. Besides its recognized cultural andscientific relevance, the species has seen remarkable growth in its economic impact due to pisciculture.

Wood inhabiting macro-fungi in tropical landscape and home-gar den trees: Their diversity and roles

open access: yesProceedings of International Forestry and Environment Symposium, 2012
Wood is a biodegradable natural resource, and is often affected by various wood-inhabiting fungi. Hence, this study was carried out to investigate the diversity and impact of macro-fungi on landscapes and home-gardens in semi-urbanized areas in Colombo suburbs.

Bioeconomic profitability analysis of tropical gar (Atractosteus tropicus) grow out using two commercial feeds

open access: yesLatin 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

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 ...

Quality Evaluation of Reference Gene Expression on Different Tissues in Adults of Tropical Gar Atractosteus tropicus

open access: yesPakistan Journal of Zoology, 2021
Tropical gar (Atractosteus tropicus) is an ancestral subtropical fish species in southeastern Mexico, which has great potential as a model species for physiological, biomedical and genomic studies. The quantification of gene expression through RT-qPCR is one of the most commonly used techniques, due to its precision, sensitivity and high performance ...

Expression of long-chain polyunsaturated fatty acids biosynthesis genes during the early life-cycle stages of the tropical gar Atractosteus tropicus

open access: yes, 2022
Long-chain (≥C20) polyunsaturated fatty acids (LC-PUFA), including eicosapentaenoic acid (EPA, 20:5n-3), arachidonic acid (ARA, 20:4n-6) and docosahexaenoic acid (DHA, 22:6n-3), are essential in multiple physiological processes, especially during early ...
