Fish live in a medium that is an especially good conductor of sound, and the myriad extant species—some 25,000 in the class Osteichthyes (bony fishes) alone (Nelson, 1984)—have evolved diverse mechanisms for transducing acoustic stimuli. It should not be surprising if sophisticated functionality in the auditory domain turns out to be a major component of the perceptual and cognitive capabilitie...

The aim of this study was to establish an experimental protocol for the artificial reproduction royal carp ‘Cyprinus carpio’ with hormonal induction spawning. For purpose, we conducted at aquaculture farm in Khemis Meliana (Ain Defla, Algeria). included six broodstock, 4 females and 2 males. Hormone injection performed dorsal muscle under fin. done successively by GnRH a dose 3 mg/kg males hCG ...

The present investigation was carried out to compare the haematological and biochemical parameters in healthy and Monogenean infected Cyprinus carpio. The haematological analysis showed significant reduction (P<0.01) in RBC, haemoglobin, haematocrit (PCV) and lymphocyte in monogenean infected fishes, whereas total leucocyte count (TLC), neutrophils, eosinophils and monocytes significantly incre...

The Common carp, Cyprinus carpio was exposed to sublethal concentrations of chromium for various exposure periods (8, 16, 24 and 32days). Serum glucose, total protein, total cholesterol, serum GOT and GPT were measured both in control and experimental fish. During various exposure periods (8, 16, 24 and 32 days), the levels of serum glucose, total cholesterol, GOT and GPT levelss were (P<0.05) ...

Ikan Mas (Cyprinus carpio) adalah jenis ikan air tawar yang memiliki peluang dikembangakan karena potensi pasar tinggi serta permintaan terus meningkat. Banyak upaya telah dilakukan pembudidaya dalam memenuhi tersebut diantaranya melakukan budidaya menerapkan teknologi intensif. Namun kenyataannya, penerapan ini sering mengalami kendala seperti timbulnya penyakit diakibatkan oleh bakteri Aeromo...

One of the most important scientific disciplines is determining toxicity heavy metals in freshwater, and there a rising concern about development methodologies for identifying toxic effects aquatic creatures. To test efficacy this approach, an experimental study was conducted on fish Cyprinus carpio from pond Bengaluru, Karnataka. Surface bioaccumulation mercury lead studies using Scanning Elec...

Freshwater fish, Cyprinus carpio were exposed to acute dose of cypermethrin at 7.5 μg/L for 1, 3, 5, 7 and 9 days and sub-lethal concentrations (1.5 μg/L) for 1,7, 14, 21 and 28 days to determine the change in enzyme activity in three functionally different tissues viz., gill, liver and muscle. Cypermethrin induced alterations that are both time dependent and tissue-specific, with glutamate deh...

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...
