Wild common carp of the Caspian Sea is one of the important fish in the north of Iran, which has been introduced to inland aquaculture. Its genetic characteristics are investigated to set up for breeding programs that are still unknown. Using wild common carp in aquaculture is limited for uncontrolled variation in performance of fish derived from undomesticated breeders. A 7×7 factorial matin...

The purpose of the study was to determine the microbiological status of 161 samples cooled and frozen fish products collected from retail markets in the Republic of Bulgaria. The highest total viable counts (TVCs) in cooled fish products were established for silver carp (7.30 log cfu/g), Black sea roach (7.28 log cfu/g) and trout (7.11 log cfu/g), followed by common carp (6.81 log cfu/g), vacuu...

The purpose of this study was to monitor the concentrations of mercury in the edible muscle, gill, liver, and skin of common carp (Cyprinus carpio) and silver carp (Hypophthalmichthys molitrix), in the Sanandaj Gheshlagh Reservoir, Iran. Mercury concentrations were assayed using Shimadzu AA 6600 atomic absorption spectrophotometer, and the results were given as µg/g wet weight. The level of mer...

In nature, the caudal fins of fish species are frequently lost to some extent by aggressive behaviour, predation and diseases. To test whether the swimming performance of fish with different swimming capacities would be differentially affected due to caudal fin loss and regeneration, we investigated the critical swimming speed (Ucrit), swimming metabolic rate (M(O2)), tail beat frequency (f(TB)...

quality grading and nutrition value determination of fish are. nowadays necessary for aquatic processing. the present study was conducted to investigate a new, applied and cheap method of fillet quality grading for common carp (cyprinus carpio) using fish size, based on mathematical equations. for this reason, 61 specimens of cultured market size carp were used and after filleting, their moistu...

In the present study, we reported infection with eighteen species of the genus Dactylogyrus, belong to thefamily Dactylogyridae from five breeder fish species, including common carp (Cyprinus carpio), grass carp(Ctenopharyngodon idella), silver carp (Hypophthalmichthys molitrix), big head carp (Hypophthalmichthysnobilis) and black carp (Myelopharyngodon piceus) which introduced and imported to ...

Supplementation of pelleted feeds (30% crude protein) consisting of practical ingredients with 250, 375 and 500 mg Cholymbi/kg diet resulted significantly improved the growth of common carp, Cyprinus carpio. Highest final average weight was recorded with diet containing 500 mg Cholymbi/kg. Feeding Cholymbi to fish showed increased carcass protein and fat. Gut protease and hepatopancreas amylase...
