Alligator gar, Atractosteus spatula, conservationAbstract
Alligator gar (Atractosteus spatula) is the largest freshwater fish inhabiting rivers draining into the Gulf of Mexico. Many gar populations have declined in overall abundance, geographical range and average individual size because of overfishing, habitat loss and alteration, high trophic level (i.e. top predators) and long life span. Considering this context, the Ecophysiology Group of the Biology Science School of the Universidad Autónoma de Nuevo Leon, designed a set of research strategies to develop captive culture techniques to reduce fisheries pressure and to restore natural populations, solving thus this faunistic problem, because it is an endemic species whose natural populations tend to disappear, with an important commercial value as it is a staple food and it is a species with a major scientific importance considering its primitive origin (having coexisted with dinosaurs). This work summarizes the information generated by the research group in ecophysiology of the Faculty of Biological Sciences-UANL, along 20 years of studies on alligator gar.
