“…In comparison with the studies performed in the natural distribution area; various parts of the western Indian Ocean, the maximum length values were apparently smaller in our study. In accordance with this, Edelist (2014) reported the maximum length of striped piggy as 14.5 cm from Israeli coasts and Ergüden et al (2015) as 17.7 cm from the Gulf of Iskenderun in the Mediterranean where is out of the native range. Along with the differences among the ecological properties of different study areas, this is probably because of that the striped piggy do not have a long history in our study area.…”

The striped piggy, Pomadasys stridens (Forsskål, 1775), is a recent invasive fish species in the eastern Mediterranean. Although its population dynamics was investigated in detail in its natural distribution area, the western Indian Ocean, an important data gap still exists in the Mediterranean. This study was carried out to determine the growth, mortality, and the length–weight and length–length relations of invasive striped piggy right after its establishment in the area. Samples were collected seasonally between April 2014 and December 2015 by using bottom trawl from 10 and 20 m depth contours off the north-western coast of the Gulf of Iskenderun. After the length, weight, and sex of fish were recorded, sagittal otoliths were extracted and examined for age determination. Then length–length, length–weight, and length at age relations, growth performance, and mortality rates were calculated for both sexes and pooled data. In the study, a total of 1131 individuals were investigated, the total length of which ranged between 7.3 and 18.9 cm. The mean length was 12.32 ± 0.11 cm. There was no significant difference between the length–weight relation (LWR) parameters of sexes and pooled data. The overall LWR was found to be TW = 0.0113 * TL^3.096 in all specimens. The von Bertalanffy growth parameters were not significantly different between males and females. The model parameters for both sexes were L∞ = 22.01 cm, K = 0.22 years–1, t0 = –1.30 years. The growth performance index (Ø′) was calculated as Ø′ = 2.03. For combined sexes, the total, natural and fishery mortality rates were Z = 1.14 years–1, M = 0.66 years–1, and F = 0.48 years–1, respectively. The exploitation rate of the stock was found to be E = 0.42. The growth performance of the invasive striped piggy population was determined to be similar to the ones reported from the Gulf of Suez where was the closest natural distribution area of the species. Although striped piggy is proper for human consumption and commercially caught in its native range, its fishery has not yet been established in the Eastern Mediterranean and we found that there was insufficient fishery pressure on the invasive population.

“…The relationship between length and weight for this species indicates that growth shows positive allometry (b = 3.094) for combined sexes. Erguden et al (2015) reported negative growth (b=2.970) in their study conducted in Iskenderun Bay. Similarly, Bilge et al (2017) stated negative allometric growth (b=2.836) from the Mugla coast.…”

“…To date, length-weight relationship studies have been reported very scarcely for the pufferfish species (Erguden et al, 2015;Bilge et al, 2017;Ayas et al, 2019). Besides, LWRs and condition factors according to sexes for T. flavimaculosus have not been reported from the Eastern Mediterranean.…”

The length-weight relationships (LWRs) of fish are helpful in fisheries science. A total of 504 yellowspotted puffer (Torquigener flavimaculosus) specimens (257 female and 247 male) were caught from the Yumurtalık coast of Turkey (Eastern Mediterranean Sea) between 2018 and 2019 by using a trammel net set with a depth range between 5 and 42 m. The sex ratio was found 1:1.08 for males and females, respectively. The length-weight relationship was described for combined both sexes by the following formula W = 0.00130×L 3.094 (r 2 = 0.918) with a positive allometric growth. Fulton condition factor (CF) was calculated as 1.713 ± 0.145 for combined sexes. This study presents the first results available for the length-weight relationships and condition factor of T. flavimaculosus according to both sexes in the Yumurtalık coast of Turkey.

“…This study reports the first record of this fish in the Syrian marine waters. The lack of scientific research in the study area [18], and fishermen ignorance to this species due to its small size (Max length 12.6 cm; [19] may had led this species not to be recorded previously in the area. This record fills the gap of O.fasciatus distribution along the eastern coast of the Mediterranean, between Iskenderun and Ashdod coasts.…”

Currently, marine species in the Mediterranean Sea is on increase; as a consequence, the Mediterranean Sea becomes a biodiversity hotspot. Apogonidae family contains 353small colourful species, which exist in the tropical and subtropical waters. On 21/3/2019,a field trip was performed in the marine waters facing Banyas city, Syria. Two specimens of the Broadbanded cardinalfish Ostorhinchus fasciatus (White, 1790) were caught, and this species has been recorded for the first time in the Syrian marine water.
