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...

Three species of stannanes were determined in different biological samples obtained from the sea water of the Arabian Gulf. Following digestion with acetonitrile, and extraction with n-hexane, the analytes were derivatized and subsequently analyzed in gas chromatography mass spectrometric system. Five-point calibrations using the concentration range of 0.05-10 μg/g were linear with coefficients...

Fish collected after a mass mortality at an artificial lake in south-east Queensland, Australia, were examined for the presence of nodularin as the lake had earlier been affected by a Nodularia bloom. Methanol extracts of muscle, liver, peritoneal and stomach contents were analysed by HPLC and tandem mass spectrometry; histological examination was conducted on livers from captured mullet. Liver...

A specimen of Mullus surmuletus with 33.6 cm in total length and 398.3 g weight was captured trammel nets along other Striped red mullet fish by fisherman off the coast Benghazi, Libya (Southern Mediterranean) on November 14, 2022. It had longest heaviest ever recorded for a Southern Mediterranean Libya.

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...

It is well established that increasing mesh number in the circumference of a diamond-mesh trawl codend can reduce size selection for round fish, whereas selection for flat fish species is unaffected. This effect has also been documented in Mediterranean trawl fisheries. In contrast, no information is available with regard to the effect of increasing mesh number in the circumference of square-me...
