The aim of the present paper is to present the results of a study on the impact intensive carp (Cyprinus carpio L.), feeding with extruded commercial feed has on the quality of cooling waters. The feed studied had varied fat and carbohydrate contents. The study also revealed the optimal hydrochemical conditions of cooling waters for carp farming. Cage farming caused growing loads of organic matter, nitrogen, and phosphorus in the water. Experimental extraction of feed from the water revealed that high fat fish feed was more stable in comparison to high carbohydrate fish feed. Intensive carp farming with these two feeds led to considerable fish weight gain in both feed groups, but the weight gain for the carp fed with high fat feed, in comparison with that of carp fed with high carbohydrate fish feed, was significantly greater (p<0.01).

Lead and cadmium levels were determined in the meat tissues of roach, bream, and carp netted in a lake and in fish ponds threatened by a pesticide tomb and in control basins in northeastern Poland. Concentrations in roach ranged from 20 to 124 ěg kg-1 of Pb and from 1 to 19 ěg kg-1 of Cd. In bream they were from 4 to 280 ěg kg-1of Pb and 2 to 28 ěg kg-1 of Cd, while in carp they were from 9 to 82 ěg kg-1 of Pb and 2 to 260 ěg kg-1 of Cd. The metal concentrations were low; no result exceeded admissible residue levels set forth by Polish law, and no evident contamination of fish by leakage from the pesticide tomb was detected.

In 2007 samples taken from carps (Cyprinus carpio L.) aged between one and two years with an average weight of 430 g were tested for selenium concentration. The fish was obtained from a 5 ha pond owned by the MILICZ Fish Breeding Farm, located in the Barycz River catchment. The following organs were taken from each 15 fishes: muscles, trunk kidneys, hepatopancrea, gills, intestine and spleen. Selenium concentrations were determined using the hydride vapour generation method. The highest selenium content was found in spleen (on average 0.848 mg Se kg–1), intestine (on average 0.651 mg Se kg–1) and kidney (on average 0.603 mg Se kg–1). The medium concentration, at 0.37 mg Se kg–1, was measured in hepatopancrea. Selenium was at its lowest concentration in gills and muscles.

W 2007 roku zbadano próbki pochodzące od kroczków karpia (Cyprinus carpio L.) o średniej masie 430 g. Ryby pozyskano z 5 ha stawu Gospodarstwa Rybackiego MILICZ, położonego w zlewni rzeki Baryczy. Z każdej z 15 ryb pobrano następujące narządy: mięśnie, nerkę tułowiową, wątrobotrzustkę, skrzela, jelito i śledzionę. Określono zawartość selenu metodą generacji par wodorków (HG AAS). W wyniku przeprowadzonych badań stwierdzono najwyższą zawartość selenu w śledzionie (średnio 0,848 mg Se kg-1), jelicie (średnio 0,651 mg Se kg-1 ) oraz nerce (średnio 0,603 mg Se kg-1). Średnią koncentracją selenu na poziomie 0,37 mg Se kg-1 charakteryzowała się wątrobotrzustka. Najmniej selenu stwierdzono w skrzelach i mięśniach ryb.

The component communities of intestinal helminths in carp, Cyprinus carpio, were investigated in six lakes in the highland of Yunnan province of southwest China. The species compositions of the communities were poor, and the degree of similarity was low between the communities. The helminth species richness of the communities was related to the lake area. The island theory may provide a good explanation for the species compositions of the helminth communities, although the fauna composition of the lakes may be the major determinant of the species compositions. However, introduction and colonization may have also played a role in determining the species richness at lease in some of the six lakes, for example in Lugu lake where C. carpio, an introduced fish was infected with Bothriocephalus sp. As these lakes are ecologically and geographically isolated and some species of fish are lake-specific, it is suggested that host-parasite coevolution may also be important in determining the parasite species compositions.

The study was aimed at the PCB (Clophen A50) accumulation dynamics in the gill filaments, muscle tissue, perintestinal adipose tissue, alimentary tract and the liver of cultured carp, Cyprinus carpio L. when taken, only, either from contaminated water or contaminated diet. The highest accumulation dynamics was observed in first 5-10 days of intoxication followed by a visible decrease resulted partly from increase in a growth rate of the tested organs and tissues as well as from the smaller daily intake per weight unit of the tested fish.

Obecność polichlorowanych bifenyli (PCB) w środowisku, ich trwałość i toksyczność stanowią poważne zagrożenie dla biosfery. W środowisku wodnym związki te jako nierozpuszczalne w wodzie kumulują się głównie w osadach dennych i organizmach wodnych. Badania dotyczyły dynamiki kumulacji PCB (Clophen A50) w listkach skrzelowych, tkance mięśniowej, okołojelitowej tkance tłuszczowej, przewodzie pokarmowym i wątrobie karpi hodowlanych (Cypinus carpio L.) przy wchłanianiu go tylko z wody i przy pobraniu z paszą. Badania analityczne wykonano metodą chromatografii gazowej. Wykazano, że obecne w wodzie i paszy PCB przenikają do organizmu ryb i charakteryzują się zróżnicowaną dynamiką kumulacji w poszczególnych narządach i tkankach w czasie 40 dni ekspozycji. Stwierdzono różnice w dynamice kumulacji w zależności od dróg pobrania toksykantów. Najwięcej PCB w ciągu 40 dni intoksykacji, niezależnie od dróg pobrania kumulowała w mokrej masie okołojelitowa tkanka tłuszczowa. W przeliczeniu na lipidy największy wzrost poziomu koncentracji obserwowano w listkach skrzelowych, a najmniejszy w okołojelitowej tkance tłuszczowej. Największą dynamikę kumulacji obserwowano w pierwszych 5-10 dniach intoksykacji, a następnie wyraźny jej spadek, który wynikł częściowo z przyrostu masy analizowanych narządów i tkanek oraz spadku podaży skażonej paszy na jednostkę masy ciała analizowanych ryb.

The purpose of the study was to evaluate an optimum dose of Aeromonas hydrophila and Aeromonas sobria antigens for the vacccination of carp (Cyprinus carpio L.) and to compare the effectiveness of the vaccination with the antigens inactivated with formalin or thermally and given intraperitoneally (ip) or by immersion (imm). The dose was evaluated with the use of formalin antigens. Doses ranging from 3 x 10⁴ to 6 x 10⁸ cells were given by injection and doses of 3 x 10⁵ to 6 x 10⁶ cells/mL of water were administered in bath. Experiments were conducted at 12°C, 16°C, and 23°C ± 1°C . To compare the effectiveness of the antigens inactivated with formalin and thermally the two doses 3 x 10⁸ cells (ip) and 5- 6 x 10⁷cells/mL (imm) were used. The effect of immunisation was evaluated with challenge tests. The relative percentage of health (RPH) and relative percentage of survival (RPS) of fish were calculated. Doses of 3 x 10⁸ cells, and 5-6 x 10⁷ cells/mL given ip and imm, respectively, were considered the most effective irrespective of the water temperature. No marked differences were found between the administration of the antigen by injection and immersion. Fish manifested a significantly higher level of immunity after the administration of formalin antigen in comparison to that following the administration of the antigen inactivated thermally.
