Total mercury (THg) and methylmercury (MeHg) concentrations were investigated in two different species from the Izmir Bay. The levels of THg and MeHg in fish tissue, ranging from 4.4 to 221.4 μg THg kg and 3.8-194.8 μg MeHg kg (wet wt.), varied according to sampling point and season. The results indicate that none of the fish analysed was ≥ 0.500 μg g for THg and ≥ 0.300 μg g for MeHg and nor d...

this experiment was conducted to evaluate the efficacy of different levels of echinacea (echinacea purpurea) methanol extract on the growth performances (final weight (fw), daily growth ratio (dgr), feed conversion rate (fcr), voluntary feed intake (vfi) and protein efficiency ratio (per) and some of hematological parameters (hemoglobin (hb), hematocrit (hct), red blood cell (rbc) and white blo...

Zinc oxide nanoparticles (ZnO NPs) have received great attention due to their optical, physical, and antimicrobial properties. They toxic effect against microbes without any on mammalians cells. are used in several applications including extending the shelf life of food. The study aims determine minimum inhibitory concentrations ZnO NPs different aquaculture fish fungus species storage period. ...

The size selectivity of trammel nets was investigated in the northern Aegean Sea using 10 different inner-panel mesh sizes ranging from 16 to 70 mm nominal (bar length). Selectivity estimates were made for eight most abundant target and bycatch fish species, namely black scorpionfish, Scorpaena porcus Linnaeus, 1758; annular seabream, Diplodus annularis (Linnaeus, 1758); red mullet, Mullus barb...

The catch of large quantities sublegal-sized fish and shrimp is a pervasive feature bottom trawl fisheries, particularly in the Mediterranean demersal mixed fisheries where regulations traditionally allow small mesh sizes. To address these concerns, two net selectivity trials were carried out 2019 2020 on fishing grounds worked by fleet Spanish Mediterranean, under normal commercial operating c...

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...

The COVID-19 pandemic had major impacts on the seafood supply chain, also reducing fishing activity. It is worth asking if fish stocks in Mediterranean Sea, which most cases have been overfishing conditions for many years, may benefitted from reduction pressure. present work first attempt to make a quantitative evaluation of effort due and, consequently, its impact stocks, focusing Adriatic Sea...
