Alligator Gar Reproduction, Growth, and Recruitment in Falcon Reservoir, Texas

SEAFWA Journal Volume 7, March 2020

Research on alligator gar (Atractosteus spatula) has increased during the last two decades; however, assessments of reproduction, growth, and recruitment remain limited for reservoir populations. We collected a total of 562 alligator gar from Falcon Reservoir, Texas, in 2014 and 2018 to estimate onset of maturity, fecundity, timing of spawning, and growth. Additionally, we modeled the relationship between spawning habitat availability and strong year-class occurrence. Age of maturity (50% mature) was 5.6 years for females and 1.2 years for males. Fecundity ranged from 79,518 to 530,398 and...
