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...

Based on the current demand fish as food, marine fishes of Sudan have been arbitrary divided into first, second and third grade fish. Examples these are red emperor (Plectroponus moculates) I, mullet II unicorn (Naso unicornis) III. This subjective grading, need to be evaluated grounds organo-leptic tests, gross chemical body parts analysis inclusion in experimentally designed feeding tests. Th...

Morphological information is given on the adults of 4 trematodes from Mugil cephalus from estuarine waters of the northern Gulf of Mexico with complementary information from specimens from Georgia. Lasiotocus glebulentus sp. n., from the Gulf, possesses a submedian genital pore and apparently differs from all known species by containing several large concretions in the excretory vesicle. Data a...

Genetic diversity as an important marker of the ecological status of aquatic ecosystems is considered a unique and powerful tool to evaluate biological communities. In order to evaluate the genetic diversity among golden mullet species (Liza aurata) in the southeast and southwest coasts of the Caspian Sea by D-Loop gene sequencing, a total of 23 fin specimens of golden mullet were collected fro...

The distribution of some heavy metals in three different organs of mullet, Liza abu, and catfish, Silurus triostegus, from Atatürk Dam Lake located on Euphrates (Turkey) was studied. Co and Mo concentrations were below limits of detection in all fish organs, whereas Ni was also below limits in organs of mullet. The metal accumulation in the liver and gill of L. abu and S. triostegus was found t...

mercury is the most toxic heavy metal in the aquatic ecosystems which originates both from natural and industrial resources and is ultimately deposited in sediments as methyl mercury. this metal is quickly transferred through the food chain and accumulated in organisms. in this study, the human health risk due to consumption of mullet ( liza aurata ) in the caspian sea, were evaluated by measur...

Shiga toxin-producing Escherichia coli (STEC) is responsible for several food-borne outbreaks worldwide. In this study, tissue samples of finfish (tilapia, n = 100) and (mullet, 100), twenty human hand swabs from fish sellers fishermen were tested bacteriologically STEC presence. Isolates their antibiotic susceptibility examined the presence eaeA,stx1, stx2 genes. E. identified tissues (36.5% 1...
