Electrospray ionization (ESI) coupled with tandem mass spectrometry has been used in conjunction with microwave-mediated saponification, periodate oxidation, and clostridial sialidase hydrolysis to enable detailed structural characterization of gangliosides and their derivatives present in mullet milt. The gangliosides extracted from mullet milt were determined to be GM3, GM3 lactone, GM3 methy...

A laboratory experiment was conducted to determine hexavalent chromium (Cr) accumulation in the mullet and investigate Cr toxicity using a panel of biomarkers including metallothioneins (MTs), glutathione (GSH), glutathione S-transferase (GST), and superoxide dismutases (SODs) for 4 weeks. Cr bioaccumulation in all tissues, except muscle, was consistently timeand dose-dependent. The accumulatio...

Stellantchasmus falcatus (Digenea: Heterophyidae) is first reported from Cambodia through recovery of the metacercariae from mullet fish and adult flukes from an experimentally infected hamster. We purchased 7 mullets, Chelon macrolepis, in a local market of Phnom Penh, Cambodia, and each of them was examined by the artificial digestion method on May 2010. The metacercariae of S. falcatus were ...

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...

Mullet is the most massively harvested species, representing third of total freshwater fish landing in Tunisia. To ensure farming durability and development country, reservoirs have been stocked with Mugilidae fry which was collected from coastal estuaries areas after a short adaptation period. The objective this paper to compare contrast Chelon ramada’’s age, growth, mortality two Tunisian (Se...

An acute mortality caused by an uncertain agent occurred in wild golden grey mullet (Liza auratus) population in the Iranian side of the Caspian Sea in February, 2004. Clinical signs of the moribund fish were erratic behavior such as spiral swimming, belly-up at rest and over inflation of swim bladder. Histological examination of brain of dead fish revealed hyperaemia, degeneration and necrosis...

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...
