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, L_T) was significantly greater than that of large-sized individuals (≥150 mm L_T). 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.
