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.
Highlights
The family Tetraodontidae, known as pufferfishes, consists of 200 species (Froese & Pauly, 2017)
The family Tetraodontidae is represented in the Mediterranean Sea by ten species (Mastsuura et al, 2011; Farrag et al, 2016)
Length-weight (LWR) relationships were calculated for: L. sceleratus (Gmelin, 1789) (n= 125), L. spadiceus (Richardson, 1845) (n= 117), L. suezensis Clark & Gohar, 1953 (n= 84) and T. flavimaculosus Hardy & Randall, 1983 (n= 28) specimens collected seasonally via different fishing methods from Muğla coasts (South Aegean Sea, Turkey) and Each fish was measured for total length (TL) to the nearest 0.1 cm and weighed to the nearest 0.01 g on board during the year of 2014, all specimens were thown back sea after length and weight measurements because of restrictive legal requirements
Summary
The family Tetraodontidae, known as pufferfishes, consists of 200 species (Froese & Pauly, 2017). The family Tetraodontidae is represented in the Mediterranean Sea by ten species (Mastsuura et al, 2011; Farrag et al, 2016). The purpose of the relationships presented here is to enable researchers merely to derive length estimates for the species, found in the Muğla coasts, that are weighed but not measured, or vice versa
