Abudefduf vaigiensis (Quoy & Gaimard, 1825)

Abstract

Abudefduf vaigiensis (Indo-Pacific sergeant) may also be known as the Sergeant major although this name is usually reserved for the closely related species Abudefduf saxatilis. Adults live in coral reefs, tide pools, and rocky reefs. It is found in tropical and subtropical waters. Depth ranges of 1 to 15 meters are where people encounter this fish. A. Vaigiensis is benthopelagic. Maximum length is 17 cm in Persian Gulf. We report for the first time from Iranian waters (Kish Island). Its maximum recorded size is 20 centimeters. Often in aggregations feeding at midwater or tending nests among rocks and coral ledges. In large numbers at spawning sites that are timed with large tides that carry their pelagic offspring far offshore. Oviparous, distinct pairing during breeding. Males turn more blue during spawning. They build nests on rocks or coral ledges. Then, females lay their eggs in the nests and the male fertilizes them. Males guard and aerate the eggs until they hatch. Eggs are demersal and adhere to the substrate. Males guard and aerate the eggs. Larva of this species live in the open sea. Juveniles associated with drifting seaweed. Juveniles mature at 12 centimeters.
