Spawning aggregations of checkered snapper (Lutjanus decussatus) and blackspot snapper (L. fulviflamma): seasonality, lunar-phase periodicity and spatial distribution within spawning ground

Atsushi Nanami

Abstract: Snappers (family Lutjanidae) are important fisheries target species and some species are known to form spawning aggregations at particular spawning grounds. The present study investigated the ecological characteristics of fish aggregations of two snapper species (checkered snapper Lutjanus decussatus and blackspot snapper L. fulviflamma) that form at a particular site. Specifically, the aims were to clarify (1) seasonality and lunar-phase periodicity of fish aggregation formation, (2) fine-scale spatial distri… Show more

“…Although a recent underwater observation study detected spawning aggregation of L. fulviflamma at specific sites during restricted lunar phases (Nanami, 2023), spawning of the species is confirmed in all lunar phases (Shimose & Nanami, 2015). The lunar periodicity of feeding activity for these two Lutjanus snappers has not previously been focused on but is expected to be different.…”
