The Nonindigenous Occurrences section of the NAS species profiles has a new structure. The section is now dynamically updated from the NAS database to ensure that it contains the most current and accurate information. Occurrences are summarized in Table 1, alphabetically by state, with years of earliest and most recent observations, and the tally and names of drainages where the species was observed. The table contains hyperlinks to collections tables of specimens based on the states, years, and drainages selected. References to specimens that were not obtained through sighting reports and personal communications are found through the hyperlink in the Table 1 caption or through the individual specimens linked in the collections tables.

Abudefduf vaigiensis (Quoy and Gaimard, 1825)

Common name: Sergeant-major

Taxonomy: available through www.itis.govITIS logo

Identification: Abudefduf vaigiensis is a member of the damselfish family Pomacentridae. It has a forked caudal fin, and the body is colored bluish-green dorsally, shading to silvery white ventrally. The species has five broad black bars on the body, the first just behind the head, the narrow fifth bar on the caudal peduncle (Randall 1995). The dorsal part of body between the first and third bars is most often yellow. During courtship, the male’s body color becomes bluer (Lieske and Myers 2004, Maruske and Peyton 2007).

This species can be distinguished from the native Hawaiian species, A. abdominalis, by the black bars on the body that are about the same width as the pale spaces in between. The black bars on A. abdominalis become narrower and fainter ventrally (Randall 1996).

Size: Maximum size is 170 mm standard length (Allen 1991)

Native Range: This marine species is widespread throughout the Indo-West Pacific from eastern Africa and the Red Sea to Tuamotu and the Line islands, and Australia northward to Japan (Allen 1991).

Nonindigenous Occurrences: Abudefduf vaigiensis was first reported in waters surrounding Maui and Oahu, Hawaii in 1991 (Mundy 2005) and is now common throughout all the Hawaiian Islands (Frédérich et al. 2009).

Ecology: Abudefduf vaigiensis inhabits a variety of rocky reef habitats to a depth of 12 m (Myers 1999). They are generalist omnivores usually found in schools feeding primarily on pelagic zooplankton, but also occasionally feed on algae and benthic invertebrates (Frédérich et al. 2009, Myers 1999). Abudefduf vaigiensis forms distinct pairs during breeding and lays eggs on a cleared hard surface that both parents guard (Lieske and Myers 2004). Juveniles can often be found in tidepools or under floating mats of seaweed (Lieske and Myers 2004).

Means of Introduction: This species likely arrived in Hawaii rafting amongst marine debris (Coleman et al. 2014).

Status: Established in Hawaii (Mundy 2005, Frédérich et al. 2009)

Impact of Introduction: Abudefduf vaigiensis has been shown to hybridize with the native A. abdominalis in Hawaii (Coleman et al. 2012). Native male A. abdominalis have been observed mating with female A. vaigiensis (Maruska and Peyton 2007). This could potentially threaten the genetic integrity of the native species. Other potential effects of this introduction have not yet been studied.
