Minnows may be more reproductively resilient to climatic variability than anticipated: Synthesis from a reproductive vulnerability assessment of Gangetic pool barbs (Puntius sophore)

•Poor reproductive resilience of minnows towards climate change is presumed.•Vulnerability of the common Gangetic pool barb towards climatic variability was evaluated.•Low threshold rainfall and wide thermal cue requirement for breeding observed.•Easiness in attainment of pre-spawning fitness and minimal risk of skipped spawning observed.•Results demonstrate – changing climate pose negligible threat to reproduction of minnows.
