The activity of glutathione-S-transferase (GST) in blood cells, liver, spleen and gonads in five Black Sea fish species horse mackerel Trachurus mediterraneus (Staindachner), high body pickarel Spicara flexuosa (Rafinesque), shore rockling Gaidropsarus mediterraneus (L.), round goby Neogobius melanostomus (Pallas), scorpion fish Scorpaena porcus (L.) caught in coastal area of Sevastopol (Black ...

The present study aimed to determine the zinc accumulation levels in gill, liver, and muscle tissues of Cyprinus carpio (Linnaeus, 1758) under effect (2.0 4.0 ppm) + EDTA 8.0 for 7, 15, 30 days effects on tissues. Tissue were determined by inductively coupled plasma-mass spectrometry (ICP˗MS). No mortality occurred fish exposure times concentrations with solutions containing only combined EDTA....

Many experimental studies have documented the impact of microcystins (MC) on fish based on either intraperitoneal injection, or oral gavaging via the diet, but few experiments were conducted by MC exposure through natural food uptake in lakes. In this study, the phytoplanktivorous silver carp were stocked in a large pen set in Meiliang Bay of Taihu Lake where toxic Microcystis blooms occurred i...

An enzyme-linked immunosorbent assay (ELISA) was developed for the detection of the egg yolk precursor vitellogenin (VTG) in the liver of medaka (Oryzias latipes) and was employed to establish an in vivo testing system for estrogen and estrogenic compounds using liver homogenates. Results of 3-month-old fish exposed to three reference chemicals (ethynylestradiol, methyltestosterone and flutamid...

This work compares the effect of the climate and some different protein diets on the activity of flesh and blow fly populations in one of the biggest mountains of Sarah region, south-west Kingdom of Saudi Arabia. Trapping of adult flies revealed the presence of three populations, namely, Engelisca adhamae (Lehrer & AbouZied, 2008) and Liosarcophaga babiyari (Lehrer, 1995), in addition to a sing...

The toxicity of cypermethrin (a pesticide) on fingerlings African catfish, Clarias gariepinus was investigate with emphasis histopathological effects. juvenile were exposed to 0, 1.0, 2.0, 3.0, 4.0 and 5.0ppb under experimental condition. growth, nutrient utilization feed parameters (Weight gain, Average Daily Weight Gain, Percentage Gain , Specific Growth Rate Feed Intake ,Feed Conversion Rati...

Non-alcoholic fatty liver disease (NAFLD) is triggered by a nutritional-metabolic alteration characterized by triacylglicerides acumulation, insulin resistance (IR), oxidative stress and depletion of polyunsaturated fatty acid (PUFA). The n-3 PUFA, such as eicosapentaenoic (EPA) and docosahexaenoic (DHA) acids, would be hepatoprotective against the development of NAFLD by stimulating lipolysis ...
