Foraging rates and substratum selection in foraging activity of checkered snapper Lutjanus decussatus (Lutjanidae) in an Okinawan coral reef
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.
