Abstract :In this study, the proximate composition of muscle tissue was investigated in lion fish insert ignore into journalissuearticles values(P. miles);, which has a high invasion potency in the Mediterranean. At the same time, the potentials of accumulation of essential and toxic metals in brain, gill, muscle and liver tissues have been examined. The study was carried out with 4 lion fish individuals insert ignore into journalissuearticles values(1st individual 278 g, 28 cm, 2nd individual 55 g, 19 cm, 3rd individual 68 g, 20 cm, 4th individual 92 g, 22 cm); caught from the Yeşilovacık Bay in 2016. Water, crude protein, total lipid, total mineral substance insert ignore into journalissuearticles values(TMS); percentages were found to be 75.68-77.62%, 20.05-21.08%, 1.11-1.84%, 1.22-1.54 in P. miles, respectively. The percentage of fatty acids in lionfish ranged from 34.26% to 37.57% saturated fatty acids insert ignore into journalissuearticles values(SFAs);, from 24.99% to 27.99 % monounsaturated fatty acids insert ignore into journalissuearticles values(MUFAs);, and from 20.49% to 49.31% polyunsaturated fatty acids insert ignore into journalissuearticles values(PUFAs);. Dominant fatty acids are palmitic acid and stearic acid from SFAs, palmitoleic acid, oleic acid, cetoleic acid from MUFAs, EPA and DHA from PUFAs. The accumulation levels of heavy metals in the tissues were found as Fe> Zn> As> Cu> Cr> Pb, respectively. The accumulation levels of each metal in the tissues were determined as follows: liver>gill>brain>muscle insert ignore into journalissuearticles values(29.19-384.43 μg g-1dw); for Fe, gill>brain>liver>muscle insert ignore into journalissuearticles values(16.08-56.68 μg g-1dw); for Zn, muscle>brain>gill>liver insert ignore into journalissuearticles values(2.69-7.88 μg g-1dw); for As, liver> brain>gill>muscle insert ignore into journalissuearticles values(0.74-7.05 μg g-1dw); for Cu, brain>gill>muscle>liver insert ignore into journalissuearticles values(0.35-2.67 μg g-1dw); for Cr, brain>gill>muscle>liver insert ignore into journalissuearticles values(0.26-2.11 μg g-1dw); for Pb. As a result; while lionfish muscle tissue contains high levels of protein, unsaturated fatty acids, minerals and trace elements, it has been determined that levels of heavy metals in this consumable tissue are not at levels that could threaten human health.
