Occurrence of the arrow Bulleye Priacanthus sagittarius (Teleostei: Priacanthidae) in the Egyptian coast of the Mediterranean Sea
Marine Biodiversity Records volume 9, Article number: 6 (2016)
Abstract
Background
Priacanthus sagittarius and P. arenatus are the only two priacanthid species recorded from the Mediterranean Sea.
Results
The Arrow Bulleye Priacanthus sagittarius is reported for the first time from Egyptian waters of the Mediterranean Sea. On 19 May 2015, a single juvenile specimen (129 mm total length) of P. sagittarius was captured at a depth of 35 m in a trawl in the waters around Alexandria, on the north coast of Egypt.
Conclusions
The current specimen represents the first record of the lessepsian P. sagittarius from Egyptian waters and the third from the Mediterranean Sea.
Background
The family Priacanthidae comprises four genera and 19 species. The genus Priacanthus represents the largest of these genera which includes 13 species (Eschmeyer 2014). Apart from P. sagittarius (Starnes 1988), only one other species of Priacanthus has been recorded from the Mediterranean Sea: P. arenatus (Froese & Pauly 2015). However, three species are known to occur in the Red Sea: P. blochii Bleeker, 1853, P. hamrur (Forsskål, 1775), and P. sagittarius.
In the present paper, we report the presence of an Arrow Bulleye P. sagittarius in coastal Egyptian waters of the Mediterranean Sea at Alexandria.
Results and discussion
Body rectangular in shape with big eyes. Dorsal fin with soft portion higher than the spinous part. Rounded caudal fin. The anterior edge of the dorsal, anal and pectoral spines poorly serrated. Scales on operculum and preoperculum. Tenth dorsal spine longer than 2nd spine. Pectoral fin reaches to above the anus. Upper margin of dorsal fin with black strip (clearly visible in the fresh specimen but disappearing or becoming faint after preservation). Pelvic fin with black blotch at its base and with dark colouration anteriorly and becoming yellowish posteriorly (Fig. 1). Anal and caudal fins with dark colour on their lower and posterior margins respectively. The description of the present specimen agrees with the description given by (Starnes 1988; Goren et al. 2010; Golani et al. 2011). Morphometric and meristic characters are summarised in Table 1.
The Arrow Bulleye differs from the three related species, P. arenatus, P. blochii and P. hamrur which occur in adjacent waters in the Red Sea, in having a black spot at the base of the pelvic fin (Fig. 1), and a long 10th dorsal spine. The number of gill rakers in P. sagittarius is smaller than in P. arenatus (28–31) and P. hamrur (24–26) (Starnes 1988).
The standard length of the current specimen (108Â mm) lies within the maximum size range given for this species by (Allen & Erdmann 2012) and (Froese & Pauly 2015) (285Â mm), but is smaller than the two specimens recorded by (Goren et al. 2010) (TL 136Â mm) and (Golani et al. 2011) (SL 181Â mm) from coast of Tel Aviv and south of Haifa Cities, Israel respectively. More ichthyological investigations of Egyptian waters of the Mediterranean Sea are necessary in order to confirm whether or not P. sagittarius has actually established a sustainable population in this region.
P. sagittarius is distributed from the Red Sea to Japan, including Australia and Samoa (Starnes 1988). The species prefers sheltered reef areas and is often found in caves or under rocks or coral plates (Froese & Pauly 2015). Although Starnes (Starnes 1988) suggested that the species lives at depths ranging from the surface down to 440Â m, (Goren et al. 2010) and Khalaf (Khalaf 2004) suggested that it may be found in deeper water. It is interesting to note that the current specimen was captured at a depth of 35Â m a result that agrees with Starnes (Starnes 1988) in having individuals of this species in layer near the surface.
Prior to the current record from Egypt, there were only two previous reports of P. sagittarius from the Mediterranean Sea, both from the Israeli coast (Goren et al. 2010) recorded the first specimen from the coast of Tel Aviv City, and Golani (Golani et al. 2011) recorded the second specimen from the south edge of Haifa, Although the current specimen represents the third record of P. sagittarius from south eastern Mediterranean, its presence in Egyptian waters suggests that the species may be extending its distribution range westwards.
Many of the invasive species have small length and unknown and the fishermen throw it back in water or putted in trash category that did not receive sufficient attention as they are caught from trash and discards. Generally, the lack of previous records of P. Sagittarius from Egyptian waters of the Mediterranean Sea may be considered an indication to the recent occurrence of such species for first time.
The circulation of the Atlantic water masses in the eastern Mediterranean Sea has received great attention and can be divided into two schools, the historical (Nielsen 1912; Robinson & Golnaraghi 1993; Malanotte-Rizzoli et al. 1997) supports a counterclockwise movement of water masses, and the recent (Millot et al. 1997; Taupier-Letage et al. 2003) favors a clockwise circulation. More recently (Hamad et al. 2005), an improved version of the historical view was introduced. It implies a counterwise in the whole eastern basin of the Mediterranean Sea, but it is more constrained along slopes, unstable and generating mesoscale eddies (Hamad et al. 2005). The water masses circulation opposite the Nile River delta was affected by the completion of Aswan High Dam in 1964 (Sharaf El-Din 1977). The general oceanographic conditions in the offshore region did not change notably, but the circulation pattern and hydrographic conditions over the continental shelf opposite the Nile delta have extremely affected. In addition, an imbalance has been produced in the near-coast sediment budget with possible increased alongshore shifting of sediments (Aleem 1972).
Since the opening of Suez Canal in 1869, it has provided a significant pathway for the invasion of many Lessepsian marine organisms into the Mediterranean Sea (Zenetos et al. 2012; Katsanevakis et al. 2014) and in the Egyptian waters where several species were reported (Golani 1998). This invasion route may well have facilitated recent immigration of the Arrow Bulleye from the Red Sea into Egyptian waters.
Conclusions
The result of the present study showed that the invasion of fish species to the Mediterranean Sea from the Red Sea and through the Suez Canal is a continuous process and species like P. sagittarius can directed to the west as well as to the east of the southern Mediterranean Sea as shown in the previous literature. This record is considered the first for the Egyptian waters of the Mediterranean Sea.
Methods
One specimen of Priacanthus sagittarius 129 mm in total length was collected from Alexandria coast of Egypt, Mediterranean Sea, 31° 13′ 46.01′′N 29° 50′ 09.53′′E on 19 May 2015 The specimen was caught using trawl net at 35 m depth (Fig. 1). The standard length, measured from tip of snout to base of caudal fin, was used for proportional measurements. The specimen was fixed in 10 % formalin and stored in 70 % ethanol. Measurements were made with dial callipers to the nearest 0.1 mm following the method of Starnes (Starnes 1988). Nomenclature follows that of Eschmeyer (Eschmeyer 2014) and (Fricke 2014). The specimen was deposited in the ichthyological collections of the Zoology Department, Faculty of Science, Al-Azhar University (Assuit), Egypt (MZSA0001).
