Abstract

We studied the effect of tourist activity on the reproductive success of sergeant major damselfish (Abudefduf saxatilis). We snorkeled at two sites – one with a bridge over the reef allowing access to the reef from the seaside (Princess beach) and further south where the number of tourists is low (Taba beach). We identified 36 (65.5%) nests on the Princess reef and 19 (34.5%) on the Taba reefs. Average nest size at Princess was 11.8 cm 2 (±2.68 SD) vs 19.6 cm 2 (±3.9) at Taba. Further, at Princess although the number of nests was not correlated to the distance from the bridge (R 2 = 0.352), average nest size increased with distance from the bridge (R 2 = 0.861). At Taba, nests on the continuous reef averaged 21.8 cm 2 (±1.8, N = 13) while those on the loose aggregation reefs averaged 14.8 cm 2 (±2.02, N = 6). Although reef tourism is increasingly being regarded a major source to generate income for human coastal communities, a better understanding of the consequences of human activities to the reef system can enhance conservation initiatives and facilitate management implementation.
