Abstract: characterization of different strains of common carp (cyprinus carpio l.) using molecular markers is essential for the management of this fish in respect to the evaluation of the potential genetic effects induced by hatchery operations and the genetic improvement of carp varieties. five microsatellite loci (mfw1, mfw2, mfw11, mfw15 and mfw20) were analyzed for the molecular characterization of four common carp strains, i.e. scaled carp, mirror carp, red carp and koi carp. we observed differences in heterozygosities and the average numbers of alleles but not in polymorphic loci (p95) among the strains. koi carp displayed the highest level of variability in terms of heterozygosity. the nm values and the fst values indicated a low level of gene flow and high level of differentiation among the strains. the highest genetic distance was observed between the scaled carp and the koi carp whilst the lowest genetic distance was found between the red- and koi carp. the unweighted pair group method with averages (upgma) dendrogram resulted in two clusters, one containing only the scaled carp and the other the remaining three varieties. microsatellite markers have been found to be effective tools for characterization of different strains of common carp.

Abstract: Despite advances in ichthyo-pathology of recent years, interpretation of fish serum biochemical parameters is often difficult by lack of reference values. That is why to know the value of the serum biochemical parameters can be a useful tool for monitoring health status, detecting illnesses and responses to therapy. This paper provides data concerning biochemical composition of carp serum (Cyprinus carpio) bred at Brate Farm of Institute of Research and Development for Aquatic Ecology, Fishing and Aquaculture from Gala i and Plea a Farm from Ploie ti, Romania. In research conducted onCyprinus carpio were determined following serum biochemical parameters: glucose (GLU), total proteins (TP), blood urea nitrogen (BUN), cholesterol (CHOL), triglyceride (TRIG), sodium (Na), potassium (K), calcium (Ca), magnesium (Mg), phosphorus (P), iron (Fe).

Abstract: The common carp subspecies (Cyprinus carpio carpio) has been regarded as an autochtonous species of Europe. Evidence obtained by comparing the parasite fauna of the European and the Asian subspecies (Cyprinus carpio haematopterus) establish that such fish in the Far East harbour a significantly richer array of parasite species, and were the exclusive hosts of most of the specific parasites, including all monogenean and myxosporean spp., until recent intensive fish translocations from the Far East. I therefore propose that the common carp originated in the Far-East. The commoncarp would have originally inhabited only the Far East freshwaters, arriving in Europe in the Middle Ages by anthropogenic transfers. During the long trip from China to Europe, the common carp lost its original parasite fauna. In its new habitat, it acquired some parasite from the crucian carp, Carassius carassius, a closely related fish. Infection of the European subspecies with the Asian parasites that had been lost in Europe recommenced only in the middle of the last century, when the Amur wild carp and the coloured carp variations became introduced to Europe. The examination of the parasite fauna of fishes is an excellent tool for surveying the origin of fishes.

Abstract: The improved Hungarian carp populations of scaled phenotype (Cyprinus carpio carpio L.,1758) of two cyprinids cultivation ponds of Tapiza and Klos respectively near Fushe-Kruja and Elbasan regions were used in this study. Six indices calculated from morphometric measures are analysed. The populations age was from 0 + (from fingerling up to 11 months) and 1+( 12 up to 23 months). The aim of study was to use the exterior indices in a selective breeding program for semi intensive cultivation conditions. Significant differences are noticed for body height index (1/H), head length index (1/cf) and index of body compress feature (O/1)at age of 0+ up to 1+ (p>0.999). After this age the differences were small. There was not significant differences for the index of body compress feature (O/1) at respective age (P<0.95). Condition coefficient( Kf) and zootecnic coefficient (Kz) increased in absolute values by age 0 to age 1+ and then the values reduced because of limited feeding. The proposed selection schemes dictate the inclusion of all exterior indices during the interval of age group 0+ up to 1+. At ages 1+ up to 2+ the selection scheme may include four indices. At ages of three and four years the selection must be based only on head length.

Abstract: Common carp, Cyprinus carpio L. is a commercial aquaculture species and also a pest fish that can destroy local aquatic communities. An effective anaesthetic method has been developed to meet both aquacultural and ecological studies of the fish. Clove oil is a cheap and safe anaesthetic for fish and humans. However, there are few reports on its efficiency on adult carps. In this study, using carp samples (average wet weight = 1.25 kg), effective concentrations of clove oil was determined by to be 50 mg L-1. The induction time taken to reach each of anaesthetic stages appeared to be inversely proportional to clove oil concentration.

Abstract: The koi carp (Cyprinus carpio L.) is a very important species in the ornamental fish culture. This fish, in relation to the variety of its colour patterns is very appreciated and it can obtain an higher market price compared to the common goldfish. In the last ten years, breeding goals have increasingly focused their attention to the morphological characteristics (Cherfas et al., 1992) and numerous research works were carried out on pigmentation and viability of different colour phenotypes (Jackson et al., 2000). More recently, several studies were set up in order to produce diploid gynogenotes and triploids (Rothbard et al., 1999)...

Abstract: Izvorni znanstveni lanak THE INFLUENCE OF DIFFERENT FOOD ON THE PRODUCTION OF MARKET CARP (Cyprinus carpio L.) Debeljak, Lj. Turk, M. Fa ai , K. Sotji , B. Puni tekst (Hrvatski) Str. 83 - 94 (pdf, 2.21 MB) downloads: 471 Sa etak This research was carried out on 8 experimental fish-pounds with individual sizes of 0,1 ha-1 on fish farm Dragani i during 1990 culturing season. Carp was reared under conditions of polyculture with total stock density 3250 ind × ha-1. (77 % carp, 2500 ind × ha-1 ; 23% -- 250 ind × ha-1 each species of herbivorous fish – silver carp, bighead, grass carp). The influence of fertilization and different feeding of fish was researched through these parameters: yield and increment of fish, individual weight, losses, food conversion, Fultons and Clark’s coefficient of carp. The hydrochemical conditions in individual pounds where researched too (tabl 2). The total increment of fish was 703 ind × ha-1 (I variant, without fertilization, feeding of carp with cereals), 1302 ind × ha-1 (variant II, fertilization, 500 kg × ha-1 NPK 17: 8: 9, feeding with cereals) and 2537 kg × ha-1 (variant III, without fertilization, feeding carp with pellets containing 20% protein of animal origin). The increment of carps was 611.4; 897.8 and 1923.5 kg × ha-1 resp. The results of production are shown on tables 3, 4 and 5. The losses of carp were similar in all variants of fish-pounds (tabl. 4). The average individual weight of carp was 30% bigger in the fish pond with fertilization, and 154% in fish pond with feeding carp with pellets containing 20% protein of animal origin in compare to control variant 1. Food conversion was lower for 26% in the variant which was fertilized, and for 13% in the variant fed with protein pellets, in compare to control variant l. The Fulton's and Clark's condition coefficient of carp was similar in all experimental ponds except in the variant III. In this variant the Fulton's condition coefficient was significantly better (P The presence of herbivorous fishes in this polyculture enlarged the total increment of fishes for 92 kg'ha-1 (variant I), 404 kg'ha-1 (variant II) and 650 kg'ha-1 (variant II!), without an inhibitory effect on the growth rate of carp.

Abstract: Common carp (Cyprinus carpio) is one of the most widely cultured fish species in the world. It is predominantly cultivated in the Balkans in the semiintensive system that is based on the utilization of natural food from the fish pond and supplemental feed (cereals, pelleted and extruded feed). Currently, an intensified type of semi-intensive production is starting to be more present in Serbia, where cereals, as the most common supplemental feed, are replaced by concentrated feed that fill in the lack of proteins from carps’ natural food in periods of its decreased production. The nutritional requirements for growth, reproduction and normal physiological functions of fish are similar to other animals, but generally fish need more proteins in their diet. Due to this, the efficiency in the use and utilization of proteins is more significant for fish than for other animals. The selection of supplemental feed in semi-intensive system of fish culture depends on the natural potential of the fish pond, culturing period, fish category, price and quality of feed.

Journal of Food Technology , 2013,
Abstract: The effect of brining on the keeping quality of gutted, ungutted, gutted common Carp (Cyprinus carpio) were monitored under low storage (deep frozen) conditions of-21Oc for 8 weeks. Three treatments were used for the study viz: Treatment 1- Normal brined Carp (saturated) Treatment 2-superbrined Carp (super saturated) and treatment 3- control- (carp with no brine treatment). These were monitored through organoleptic (cooked and uncooked) and chemical tests (TVB) to indicate extent of spoilage. Weekly variations in mean weights and initial and final proximate composition of fish in each treatment were also monitored. A concurrent loss in weight was recorded form 1st- 3rd week in all the brining treatments employed and equally affects the fillets, gutted and ungutted samples. This suggests displacement of locked up water which could have accelerated spoilage in the tissue of the fish (Cypriuns corpio) by salt crystals, hence the corresponding loss in weight of the fish, weight loss was negligible in Treatment 3, the control fish without brining. The correlation efficient (r) for TVB values with length of storage were positive in all cases for gutted, ungutted, and fillttetted samples (super brine -0.80, 0.84 and 0.87), (Normal brining -0.86, 0.90 and 0.44) and (control -0.98, 0.94 and 0.62 respectively) which implies TVB values increases with the spoilage rate/ length of experimental period. However delayed production of TVB were experienced in Treatments 1 and 2 (Normal and superbrined fish) up to the end of the 5th week which suggests that brining in whatever form causes delayed responses to spoilage in deep frozer Cypriuns carpio. The much lower crude protein (6.59-15.42% (Super brine) and 9.62-13.22% (Normal brine) and higher ash content 16.85-18.78% ash (super brining) and 12.08-16.77% ash (normal brine) on proximate analysis of the final fish products for normal and supper brined fish suggests salt protein denaturation coupled with cell (tissue) damage by the frozen salt crystals. The larger surface of exposure of the fillets in Treatments 1 and 2 and there thinness compared to gulled and ungutted samples makes it a better preserved product and it is also responsible for the higher degree of saltiness. All measured parameters the organoleptic assessment (cooked and uncooked), weight loss and TVB values followed a similar pattern of variation. However, there was no delayed response in the TVB production for the control fish which commenced at the 2nd week for fillet control (4.89-24.49 mg 100 gm 1 fish), ungutted control (9.79-26.93 mg 100 gm 1 fish) compared to much lower values recorded for normal and superbrined products from the 6th-8th week. Normal brining should be done to deep frozen Cyprinus carpio to reduce the degree of saltiness to taste. However, if a more permanent product form/preparation) is desired, like it is the case if further processing to Carpfish meal, cake or paste superbrining is recommended in the fillet form to enhance
