“…They also observed a high frequency of skipped spawning, which likely serves as an adaptive behaviour to mitigate impacts of environmental variability. Šmejkal et al [ 23 ] monitor reproductive aggregations of asp ( Leuciscus aspius ) in a Želivka Reservoir tributary in the Czech Republic in relation to different environmental cues, including water temperature, discharge, temperature, precipitation, atmospheric pressure, wind speed and lunar phase, as well as temporal changes. The study shows that the observed variability is sex-dependent, with reproductive aggregation size being positively affected by water temperature and wind speed, and highest during the period before and after the full moon and at night.…”
