Spawning time of black sea bream Acanthopagrus schlegelii, related to underwater photoperiodism in oyster farms

Abstract: The embryonic development times, spawning timing and hatching rates of the black sea bream Acanthopagrus schlegelii were examined to investigate the potential effect of seawater temperature, tides and photoperiod on the reproductive rhythm of this species in Hiroshima Bay, Japan. Low temperatures decreased hatching rates and extended the hatching time, and the minimum temperature threshold for hatching was 15 C. Back-calculated spawning times indicated that the peak of spawning occurred just before sunset and … Show more

“…Decreased cumulative water temperature could imply a higher daily water temperature, therefore both correlations could finally imply the same. This trend has been observed in several other species, such as salmon, tuna, cod, black sea bream and flounder (Gillooly et al ., 2002; Gordoa & Carreras, 2014; Kawai et al ., 2022; Kurita et al ., 2011). In this study, we could not obtain data for hatching rate, egg size or developmental stage.…”
