To elucidate the effects of seasonal variation of precipitation on the distribution of polychlorinated biphenyls (PCBs) in estuarine sediments and benthic feeders, PCB concentrations of river surface sediments and mullet fish (Liza macrolepis) were investigated in the estuary of Er-Jen River near former PCB contamination sites before and after each wet season from 2002 to 2004. Analyses of grai...

To evaluate the risk of Anisakiasis in the population, a common zoonotic disease worldwide caused by ingestion of larvae (L3) of the nematode family anisakidae (Anisakis spp, Contracaecum spp, Pseudoterranova spp) present in raw fish or undercooked constitute a health risk that should not be underestimated; fish caught in the area Golfete of Coro, Venezuela Falcòn state. Artisanal trawling shor...

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...

Incorporating indigenous knowledge into fisheries management is becoming increasingly important in the derivation of alternative management solutions. It also satisfies the political demands of indigenous communities to exercise their rights and responsibilities to traditional resources and their management. Using a methodology that considers perceptions or constructs of the environment to be d...

Quality of fresh milt of grey mullet Mugil cephalus Linnaeus, 1758 was assessed based on motility grade, motility duration, sperm count and seminal plasma osmolality. Freshly collected milt from live males (n=17) were examined individually for motility assessment. Motility grade was four in fifteen samples whereas three in other two samples analysed. Other sperm quality parameters such as motil...

The present study was performed to trace the decisive evidence for mixed infection of 2 Myxobolus species, M. episquamalis and Myxobolus sp., in the gray mullet, Mugil cephalus, from Korean waters. Mullets with whitish cyst-like plasmodia on their scales were collected near a sewage plant in Yeosu, southern part of Korea, in 2009. The cysts were mainly located on scales and also found in the in...

Anisakiasis is a parasitic infection caused by larval stages of nematodes of the genus Anisakis, Pseudoterranova and Contracaecum, of the Anisakidae family. The lifecycle of these nematodes develops in aquatic organisms and their final hosts are marine mammals. However, humans can act as accidental hosts and become infected with infective stage larvae (L3) by consuming raw or undercooked fish o...

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...

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...
