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. |
