While magnetoreception in birds has been studied intensively, the literature on magnetoreception in bony fish, and particularly in non-migratory fish, is quite scarce. We examined alignment of common carps (Cyprinus carpio) at traditional Christmas sale in the Czech Republic. The sample comprised measurements of the directional bearings in 14,537 individual fish, distributed among 80 large circ...

CIRKOVIC, M., N. MILOSEVIC, M. MARKOVIC and A. POTKONJAK, 2010. Brain myxoboliasis of common carp. Bulg. J. Agric. Sci., 16: 263-265 The common carp (Cyprinus carpio) originating from Serbian fish ponds was examined for presence of Myxobolus encephalicus. The spores of M. encephalicus were present in blood vessels and meningeal layers. Its presence has been noted in 32-days old carp fingerlings...

Cellulose and xylan are the most common Non-Starch Polysaccharides (NSPs); they are available in plants and they exhibit anti-nutritional effects. The present study is intended to detect cellulose and xylan degrading autochthonous gut bacteria in Indian major carps (Labeo rohita, Catla catla, and Cirrhinus mrigala) and exotic carps (Hypophthalmichthys molitrix, Ctenopharyngodon idella, and Cypr...

The study was undertaken to determine bacterial contamination of warm-water fish ponds and silver carps harvested from those ponds in Guilan province, Iran. In this respect, water samples were taken from 7 ponds and investigated by testing total bacteria, coliforms, and Escherichia coli. In addition, skin swab samples of silver carps caught from each pond were studied for enumeration of the sam...

The aim of the present study was shedding light on disease factors underlying mortality event among common carps inhabiting Hirfanlı Dam Lake in Türkiye spring year 2021. For this purpose various parasitological, bacteriological and virological research techniques were employed. Five parasite genera, Dactylogyrus spp., Myxobolus Eimeria Trichodina Diplostomum spp. isolated from 13 carps. opport...

The effect of phenol on haematological components of Indian major carps, Catla catla, Labeo rohita and Cirrhinus mrigala were observed. After exposure to sublethal concentrations of 5.17 mg l(-1), 6.06 mg l(-1) and 6.99 mg l(-1), the number of red blood cells, haemoglobin content and packed cell volume all decreased but the glucose level increased. The order of decrease in the haematological co...

trauma to primary teeth can lead to devastating sequels in development of permanent successors. the disturbance may range from enamel hypoplasia and/or hypo-calcification to arrest of dental bud development. crown dilaceration of permanent teeth is one of the consequences of trauma to deciduous teeth mainly due to intrusion or avulsion. this report presents a mandibular central incisor with dil...

Bigheaded carps (bighead carp, Hypophthalmichthys molitrix, and silver nobilis) their hybrids play an important ecological economic role in original habitat, while introduced stocks may pose serious risks. To address questions about the persistence invasiveness of these fish, we need to better understand population structures. The genetic structures bigheaded carp populations inhabiting Lake Ba...
