<p dir="ltr">Hydropeaking can expose adhesive fish eggs to air, threatening reproduction in regulated rivers.
Description
Yet risk is commonly assessed by exposure duration rather than physiological condition. We tested how relative humidity, temperature and light intensity affect dehydration and hatching success in common carp (Cyprinus carpio) eggs attached to shallow substrates.
Water loss was rapid initially but slowed over time; it increased with temperature and light intensity and decreased with relative humidity. Free water accounted for 67–84% of cumulative loss before hatching success declined sharply. Hatching success decreased nonlinearly with water loss, with 50% hatching predicted at 28.57% loss.

Low-field nuclear magnetic resonance showed selective depletion of free water, while scanning electron microscopy revealed early envelope changes followed by cracks, peeling and local collapse. These results identify egg water loss as a physiologically meaningful and potentially transferable indicator of hydropeaking risk, linking river regulation, microclimate and reproductive failure.</p>
