Fish farming is the only type of aquaculture in Serbia. Fish farming is mostly carried out in cyprinid and salmonid (trout) fishponds (over 95% of the total fish produced), with considerably lower ichthyoproduction being practiced in cages and some bodies of open water such as reservoirs and channels. Serbian aquaculture currently includes 12 fish species, 4 of which are allochthonous (non-nati...
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 contaminationinduced 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 we...
24 Tc1-like transposons consist of an inverted repeat sequence flanking a transposase gene 25 that exhibits similarity to the mobile DNA element, Tc1, of the nematode, Caenorhabditis 26 elegans. They are widely distributed within vertebrate genomes including teleost fish; 27 however, few active Tc1-like transposases have been discovered. In this study, 17 Tc1-like 28 transposon sequences were i...
The aim of this study was to determine the selectivity of monofilament gillnets with different mesh size for silver crucian carp in Eğirdir Lake. In this study, it was investigated that the selectivity of monofilament gillnets with nominal mesh size (stretched) with 32, 40, 50, 60, 70, 80, 90 mm and trammel nets with 100, 110, 120, 130, 140, 150 mm for catching of silver crucian carp. Fieldwork...
The silver carp (Hypophthalmicthys molitrix) compnses about 50% to 85% of the composition offish species in the polyculture system of warm water species in Iran. However, the difficulty in preparation of this species and the presence of pin bones are among the main reasons to restrict the demand of this species in the domestic markets, particularly in non coastal provinces. The objective of th...
The common carp (Cyprinus carpio) belongs to the family Cyprinidae. In nature, carp live in the middle or lower reaches of a river with slow currents, or in marshes. Their habitats are usually weedy areas with a muddy bottom. Carp fry feed on zooplankton such as rotifers and copepods, but as they grow up they become benthic feeders, feeding on animals and other organic material. The cyprinids h...
this study was conducted to evaluate the effects of freeze-thaw cycles on some quality parameters of silver carp fillets. the prepared fillets were packaged in zip lock bags and were subjected to 0, 1, 2, 3, 4 and 5 freeze-thaw cycles, respectively. heme iron content decreased, and dry matter increased as the number of freeze-thaw cycles increased (p
background: maturity of silver carp (hypophthalmichthys molitrix) ovary takes place at 2-8 years old and it is depends on photoperiod and environmental water temperature. objectives: the aim of this study was to identify macroscopical and microscopical structure of silver carp ovary in two categories of body weight, total body length and at 2 and 4 years old in khuzestan province climati...
Quality of minced silver carp (Hypophthalmicthysmolitrix) with gum arabic encapsulated with 1 and 1.5%( w/w) and rosemary extract (RE) (1 and 1.5% w/w) stored at 4˚C was studied chemically (peroxide value and total volatile nitrogen) and microbiologically (total viable count, psychrotrophic count) analyses. The efficacy of the encapsulated extract to control the population of Esche...
