Length-Weight Relationships of Four Lessepsian Puffer Fish Specıes From Muğla Coasts of Turkey

Abstract

In this study, length-weight relationships were given belonging to Tetraodontidae family: Lagocephalus sceleratus (Gmelin, 1789), Lagocephalus spadiceus (Richardson, 1845), Lagocephalus suezensis Clark & Gohar, 1953 and Torquigener flavimaculosus Hardy & Randall, 1983. Specimens were collected via different fishing activities (e.g. longline, trammel net, bottomtrawl) from Muğla coasts (South Aegean Sea, Turkey) during 2014. Specimens were thown back sea after length and weight measurements because of restrictive legal requirements. Minimum, maximum and mean total lengths and weights were established as 5.3, 10.6, 7.25 cm, 3.96, 31.57, 11.28 g for T. flavimaculosus, as 16.7, 63.8, 29.34 cm, 64.36, 2968.42, 342.39 g for L. sceleratus, as 11.8, 27.9, 16.48 cm, 27.98, 287.48, 74.24 g for L. spadiceus and as 8.6, 15.9, 10.62 cm, 7.94, 43.56, 15.47 g for L. suezensis, respectively. LWR equations were calculated as follow: W= 0.03761 *L2.8363(R2= 0.896) for T. flavimaculosus, W= 0.01646 *L29272(R2= 0.974) for L. sceleratus, W= 0.03327 *L2.7315(R2= 0.913) for L. spadiceus and W= 0.02138*L2.7586(R2= 0.871) for L. suezensis. Four pufferfish species were show negative allometric growth (A-) model.

Spatio-temporal distribution of pufferfish (Tetraodontidae) along the Turkish coast of the Mediterranean Sea

“…The L-W relationship of L. sceleratus was in line with the results of other studies in the eastern Mediterranean (Kalogirou, 2013;Boustany et al, 2015;Farrag et al, 2015); however, Başusta et al (2013a) found L. sceleratus with a b value in Iskenderun Bay lower than our findings and the findings by Aydın (2011) in the Gulf of Antalya. Furthermore, Bilge et al (2017) estimated negative allometric growths for four common pufferfish species along the coasts of Muğla, adjacent to the present study area.…”

“…Early studies on pufferfish focused mainly on initial reports on their first records (Bilecenoglu et al, 2006;Tuncer et al, 2008;Koç et al, 2011;Turan & Yağlıoğlu, 2011;Irmak & Altinağaç, 2015;Akyol & Aydın, 2016Çelik et al, 2018), length-weight relationships (Başusta et al, 2013a,b;Bilge et al, 2017), population growth (Aydın, 2011;Farrag et al, 2015), and biological parameters (Boustany et al, 2015) of a single species when studying the spatio-temporal distribution of the pufferfish (Kalogirou, 2013;Farrag et al, 2015;El-Haweet et al, 2016;Özbek et al, 2017). Kalogirou et al (2010Kalogirou et al ( , 2012 studied relationships between Posidonia spp.…”

The length-weight relationship and condition factor of yellowspotted puffer Torquigener flavimaculosus Hardy & Randall, 1983 in the Eastern Mediterranean (Yumurtalık Bight, Turkey)

“…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. However, Ayas et al (2019) reported positive allometric growth (3.326) from Mersin Bay.…”

“…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.…”

Some biological characteristics of the smooth blaasop puffer fish Lagocephalus inermis (Temminck and Schlegel, 1850), from south-eastern Arabian Sea

“…Length-weight relationship (LWR) for the genus Lagocephalus has been reported by many researchers from India and abroad (Naik and Jalihal, 1998;Joshi, 2004;Simon and Mazlan, 2008;Başusta et al, 2013;Sirisha and Rao, 2013;Bilge et al, 2017;Padmavathi et al, 2017;Anju et al, 2019). Limited studies on the biology of L. inermis are available from India (Joshi, 2004;Padmavathi et al, 2017;Anju et al, 2019).…”
