Diazinon is widely consumed for plague control in the agricultural farms and in domestic and aquaculture aspects. The present research purposed to evaluate the effect of half-lethal concentration (LC50) of diazinon on some biochemical and hematological parameters of silver carp, hypophthalmichthys molitrix, after 0, 24, 48 and 96 h. The results showed that the values of leukocytes (WBC), haemat...

This paper describes seasonal changes of microcystin-LR (MC-LR) and its glutathione (MC-LR-GSH) and cysteine conjugates (MC-LR-Cys) in three aquatic animals--snail (Bellamya aeruginosa), shrimp (Macrobrachium nipponensis) and silver carp (Hypophthalmichthys molitrix) collected from Lake Taihu, China. MC-LR, MC-LR-GSH, and MC-LR-Cys were determined by liquid chromatography electrospray ionizatio...

Carp silver fish is characterized by mating more than once a year and its growth is very fast as it weighs after one year from 1 to 2.5 kg after two years and 4 kg in the third year and up to 15-20 kg after 5 years and the turning cycle 7 months since hatching and even marketing. It is a good economic source of animal protein as it has the ability to convert weeds and grasses and algae in the e...

Both adult females and males of Argulus mongolianus Tokioka, 1939 were collected from the buccal cavity wall body surface freshwater fishes in Lake Izunuma Uchinuma, Miyagi Prefecture, northen Honshu, Japan. The original description species was insufficient, based on a single female Inner Mongolia, China, no further has been made to date. Thus, this paper redescribes A. newly-collected specimen...

Different pollutants have undesirable effects on aquatic ecosystems, detergent powder is one of the elements in the sewages so study on the effects of this factor on  aquatic animals is crucial. The aim of the present study was to investigate acute effects of detergents as potentially dangerous additive to assess mortality effects of this product on some cultured fish. Silver Carp (Hypopht...

The prevalence of fish-borne zoonotic trematode (FZT) metacercariae was investigated in fish farmed by rural households in Nghe An Province, located in northern Vietnam. In total, 716 fish, including tilapia (Oreochromis niloticus) and 6 carp species, i.e., grass carp (Ctenopharyngodon idellus), bighead carp (Aristichthys nobilis), mrigal (Cirrhinus mrigala), common carp (Cyprinus carpio), silv...

Background: Copper is a trace element vital to life, but the toxic effect of water pollution with it on fish is now exhibited. Fish blood is susceptible to contamination-induced stress and its alternation due to the hematological and immunological parameters can be utilized as toxicity indices of xenobiotics. Methods: In this study, juvenile species of silver carp with average weight of 200gr...
