Abstract: The reproductive behavior and spawning cycle of the gobiid fish
Eviota abax were observed in a rocky tide pool at Nobeoka, Miyazaki, Japan.
Both sexes maintained nonterritorial, overlapping home ranges. The spawnings
took place at the low tide of neap to spring tidal periods. Matings varied in each
spawning cycle, but males did not simultaneously mate with multiple females.
Males were larger than females in the spawning pairs. After spawning, only the
male guarded the egg mass. Although separated by 900 km, the basic patterns of
reproductive ecology were similar at Nobeoka to those reported earlier for this
specie,s from Kominato, Chiba, Japan; nest entrances were smaller at Nobeoka
than at Kominato, and larger males kept their home ranges longer at Nobeoka.
