Foraging rates and substratum selection in foraging activity of checkered snapper Lutjanus decussatus (Lutjanidae) in an Okinawan coral reef
Abstract:The activity patterns and substratum selection for foraging of checkered snapper Lutjanus decussatus were observed. The foraging rate of small-sized individuals (<150 mm in total length, LT) was significantly greater than that of large-sized individuals (≥150 mm LT). There was significant positive use of live branching corals, whereas negative use of coral rubble, rocks and sand for both small-sized and large-sized individuals.
