Stock size and status of red mullet Mullus barbatus were assessed via virtual population analysis yield prediction using on-board observed length-frequency catch data from the north-eastern Mediterranean Sea. The von Bertalanffy growth parameters obtained L∞ = 35.4 cm, k 0.42, t0 0.64, tanc 0.59 Φ′ 2.72. Trawl-type selectivity ogive was calculated as 1.57 years corresponding to 17.1 cm TL. M. i...

population dynamic parameters of red mullet, mullus barbatus (n=592) caught by trawlers operating in arzew gulf (algeria) in the western mediterranean were studied. samples were collected between february 2013 and january 2014. females ranged from 10.9-23.2 cm in total length and 12-149.2 g in weight whereas males length was comprised between 12.6 and 19.7 cm and weight between 21.3 and 99.9 g....

This study was carried out in 13 fishing operations the inner harbor area of Sinop, from September through November 2004. Trammel nets were used, which has 32 mm mesh size and target fish species gear is red mullet (Mullus barbatus) study. Three net groups used experiments, without selvedge (A0) for control net, multifilament with (A1) monofilament (A2) respectively. 65.3% Osteichthyes (696 ind...

Otolith mass asymmetry can significantly affect the vestibular system functionalities; usually, X values of vary between −0.2 and + 0.2 (−0.2 < 0.2). These change during a fish life therefore they are not related to total length. We collected 404 specimens from Gulf Tunis, including three pelagic species: Sardina pilchardus (Walbaum, 1792) (74 otolith pairs), Trachurus mediterraneus (Ste...

Baseline levels of cadmium and lead were determined in muscle tissue and liver of hake (Merluccius merluccius) and red mullet (Mullus barbatus), two commercially important fish species from the eastern Adriatic. Concentrations of trace metals in liver (Cd: 6-183 microg kg(-1) w. wt. ; Pb: 39-970 microg kg(-1) w. wt.) were within the range of recently published data for the Mediterranean. In the...

This study investigated seasonal variations of antioxidant defense enzyme activities: total, manganese, copper zinc containing superoxide dismutase (Tot SOD, Mn SOD, CuZn SOD), catalase (CAT), glutathione peroxidase (GSH-Px), glutathione reductase (GR) and biotransformation phase II enzyme glutathione-S-transferase (GST) activity in the liver and white muscle of red mullet (Mullus barbatus). Th...

Mercury (Hg) is a pollutant that has toxic effects on ecosystems and biota. As it biomagnifies in the food chain, its presence edible fish poses high risk to human health. Herein, total Hg (THg) content was quantified 2018–2019 using thermal decomposition amalgamation atomic absorption spectrometry muscle tissue of red mullet (Mullus barbatus), commercially important species throughout Adriatic...
