Farming and trading of aquarium fish has been considered a popular pastime in the world. Most Iran's are imported from Asian countries including Indonesia, Malaysia, Thailand Vietnam. Fish lice (Argulus) is known as one most important common ectoparasites ornamental fish. Reports indicate that these parasites have observed to Iran (e.g goldfish Carassius auratus koi carp Cyprinus carpio). Today...

Lethal effects of nitrogenous compounds ammonia, nitrite and nitrate on freshwater fish Cyprinus carpio were studied and the static LC50 values obtained for these 3 toxicants for 24 hr were 0.80 ppb, 171.36 ppm; 1075.10 ppm and continuous flowthrough LC50 values for 24 hr were 0.72 ppb, 154.31 ppm; 967.63 ppm respectively. The fish were exposed to lethal concentrations to study the changes in h...

The main objectives of this study were to study the parasitic infestation of Lernaea cyprinacea in 4 cyprinids from the Choghakhor Lagoon, Chaharmahal - Bakhtyari Province, west of Iran. A total of 180 cyprinids including Cyprinus carpio (n=101), Carassius auratus (n=47), Capoeta aculeata (n=10) and Alburnus alburnus (n=22) caught, and were studied for Lernaea cyprinacea infestation. Prevalence...

This study was aimed of determining the relationship polymorphism growth hormone receptor gene with some traits (daily rate, relative and specific growth, ratio efficiency feed conversion) in 45 samples common carp (Cyprinus carpio). The following are most important results obtained: DNA sequencing single nucleotide (SNP) showed there three mutations sites C24074T, A24375G G24485A. No genetic m...

This study evaluated the effects of diets containing 0, 2.5, 5, 7.5 and 10% Arthrospir platensis on skin pigmentation, growth performance, and digestive enzymes of (Koi, Cyprinus carpio). A completely randomized experimental design was developed with five treatments and three replicates. One hundred and fifty koi fish with average initial weight of 30±1g were assigned to fifteen experimental ta...

Bifenthrin is used as insecticide in agriculture. Present manuscript deals with the poisonous outcome of bifenthrin on histology kidney fish Cyprinus carpio. Freshwater carpio was this experimental study. An aggregate 30 were arbitrarily separated into 3 gatherings A, B and C. Group A kept control while C treated exploratory. All glass aquaria at room temperature. During experiment, group (cont...

This study was designed to better understand the possible effects of channelization by comparing natural and previously channelized sections of the Cache River and Bayou DeView. Forty-five fish species were collected innatural reaches, but only 24 species were collected in channelized reaches. Cyprinus carpio and Dorosoma cepedianum constituted 40 and 20 percent of the total fish biomass in cha...
