the aim of this study was to determine the concentration of copper and hazard quotient (hq) in muscle of the carp aquaculture fishes (common carp) (cyprinus carpio), grass carp (ctenopharyngodon idella), big head carp (aristichthys nobilis) and silver carp (hypophthalmichthys molitrix)] in khuzestan province. 108 pieces farmed fish sampled was prepared from the azadegan warm water fish culture ...

The article presents the results of researches conducted on Lake Ozgent (the Kyzylorda region). data hydrochemical regime lake, ionic composition, composition biogenous compounds, oxygen and thermal regimes were collected analysed. There has been done assessment food supply current state ichthyofauna. According to obtained data, recommendations about using made, recommended meliorative events (...

 Euglenophyte bloom is a common problem in most of the aquaculture ponds in Bangladesh. In the present study we conducted an experiment to control euglenophyte bloom for achieving better fish production using duckweed (Lemna minor) and lime. The experiment was carried out using four treatments, i.e., ponds were supplied with duckweed (T1), lime treatment (T2), both duckweed and lime (...

The utility of environmental DNA (eDNA) as a detection tool for fisheries management is limited by dilution and degradation, especially in areas low fish abundance. This proof-of-concept study addressed these challenges testing whether food or pheromones might be used to attract invasive carp so they can measured more readily using eDNA. In two experiments, PIT-tagged were stocked into ponds (N...

abstract- in this study, texture profile analysis and a creep test were used to determine the textural quality attributes of fish protein isolates and conventional surimi. these isolates were made from raw materials obtained from filleting processes of silver carp (hypophthalmichthys molitrix) using acid and alkaline aided treatments. texture profile analysis was performed in order to obtain ha...

Leptin is an important hormone for the regulation of food intake, energy expenditure and reproduction in mammals, but information regarding its role in teleosts remains scant. In the present study, the gene structures of grass carp (Ctenopharyngodon idellus) and silver carp (Hypophthalmichthys molitrix) leptins were characterized. Recombinant grass carp leptin (rgc-LEP) was expressed in Escheri...

Carp is one of the most widely cultivated warm water fish, which has been introduced into many countries. It is essential for the manager of a carp farm to know the production costs and their evolution, showing the main inputs on which the cost reduction is worth effort. In Iran, carp farming is mainly based on common carp, silver carp, grass carp, and bighead carp, which were often reared in p...
