The aim of this study was to determine the protozoan parasites in common carp (Cyprinus carpio, L. 1758) from the largest cyprinid aquaculture facility in Macedonia, located in Pelagonia region (Bitola). This study was carried out by seasons, in a period of three years. A total of 212 specimens of common carp were examined and 134 fish (63.20%) were infected with protozoan parasites. Representatives of Protozoa were most commonly occurred during the spring (in 58.27 % of the fish examined), than in winter (55.21 %), summer (39.07 %) and the lowest in autumn (35.64 %).In common carp from this cyprinid fish farm the presence of 4 protozoa species was established: Myxobolus müelleri, Myxobolus encephalicus, Thelohanellus nikolskii and Trichodina sp. The mean intensity with protozoan parasites in common carp was 3.60, while the prevalence 10.20 %.

Carp Cyprinus Carpio

Fish in stressed conditions will show symptoms of a decreased physiological function. These symptoms include changes in the respiration system (gills, breathing frequency) and blood hemoglobin. Cyprinid fish are active fish that require high oxygen levels. In a minimum oxygen condition, cyprinid fish are easy to get stressed. Despite the extensive literature on cyprinid biology, comparison of declined physiological functions due to oxygen depletion in cyprinid are few and far between. The purpose of this study was to determine the physiological reactions and organ responses of three species of Cyprinidae, common carp (Cyprinus carpio), nilem carp (Osteochilus hasselti), and Torsoro carp (Tor soro) challenged to oxygen depletion. The study was conducted using 18 fishes for each species with an average body weight of 48.11 ± 4.24 g. Oxygen depletion challenge was done by placing the test fish in closed and non-aerated aquaria (40 cm x 20 cm x 20 cm). The dissolved oxygen level in each aquarium was measured every 30 minutes. Fish breathing frequency was calculated by the frequencies of mouth movement every 30 minutes. Histological examination of gills and blood was taken from healthy fish (at the beginning of treatment) and at LC50 (lethal concentration). The results showed that oxygen depletion reduced blood hemoglobin levels down to 5.1 ± 1.4 gram%, 3.3 ± 1.15 gram%, and 1.5 ± 0.71 gram% for goldfish, nilem, and torsoro, respectively. The respiratory rate varied from normal to depleted conditions. When depletion occurred, the respiratory rate increased and decreased again when the fish started to get weak. In normal conditions, the breathing frequency of goldfish was 60 beats/minute, nilem was 108 ± 20.8 beats/minute, and Tor soro was 144 ± 31.7 beats/minute. The highest respiration frequency occurred in tor soro fish in the 150th minute with a value of 216 ± 0.0 beats/minute. The fastest mortality at LC50% occurred in torsoro at 245.00 ± 17.32 minutes.

The Common carp, Cyprinus carpio is an exotic fish in Lake Naivasha. It is one of the commercially important species in the lake. This study investigated on its biology and population parameters during 2017. Fish samples (433) were caught using gillnets of mesh-sizes 2-5 inches. Length of fish ranged from 12.0 to 69.0 cm TL, and weighed between 32 and 6840 g. The overall population sex ratio was 1.66: 1.0 (male: female). The mean length of females was 34.8 cm and males 32.1 cm. The length at first maturity was calculated at 54.0 and 49.0 cm for females and males, respectively. The mean condition factor for all fish was 1.05. The peak condition values were recorded during April (1.35), September (1.59) and October (1.80). There was a significant difference in mean condition factor within the size classes highest (1.38) and lowest (0.93) values recorded in class 56-60 and 26-30, respectively. The overall asymptotic length (L∞) was 73.5 cm and growth curvature (K) 1.05 yr-1 with growth performance index (Ф) of 3.72. The total (Z), natural (M), fishing (F) mortality coefficients 2.85, 1.34 and 1.78 yr-1, respectively. The exploitation rate (E) of 0.57 was higher than optimum sustainable yield (E0.5) of 0.32, but not different from maximum sustainable yields (Emax) 0.54 and economic yield (E0.1) 0.46. The length at first capture (LC50) was lower than length at first maturity (LM50), suggesting capture of immature fish. This study provides parameters of fish biology and population often useful in fisheries management.

Abstract A total of 958 specimens of farmed common carp Cyprinus carpio from eight of the most significant and largest cyprinid aquaculture facilities in Macedonia (pond and cage culture systems) were examined for parasitological investigation for three years. The following parasite species of the genus Dactylogyrus were identified: Dactylogyrus extensus, Dactylogyrus minutus and Dactylogyrus anchoratus. The highest prevalence was determined for D. extensus (38.8%), followed by D. minutus (7.9%) and D. anchoratus (2.8%). The highest mean intensity was determined for D. extensus (6.2), followed by D. minutus (4.7) and D. anchoratus (3.8). By seasons, the highest prevalence (16.5%) was recorded for D. extensus in winter, while the lowest (0.6%) for D. minutus in autumn. The highest mean intensity (8.0) was also determined for D. extensus in winter, and the lowest (1.9) for D. minutus in spring.

Background: Fecundity is an important parameter in fisheries that predicts the reproductive capability of fish stock. Information on the fecundity of Common carp is helpful in estimating the amount of offspring produced in spawning season, which is essential for the stock assessment of the species. Assessment of the fecundity of a fish is essential for evaluating the commercial potentialities of its stock, life history, practical culture and actual management of the fishery. Common carp is a commercially important fish which has the potential to meet the demand of food in the country. Scanty of data is available on fecundity parameter of common carp in Kashmir waters. Therefore, this research work aims to estimate the fecundity of Common carp collected from the Dal lake of Kashmir. Methods: The present study aims to estimate the fecundity of Common carp, [Cyprinus carpio var. communis] existing in Dal Lake, Kashmir. The 30 fish samples were collected once every month from the month of January 2018 to December 2018. Fishes were brought to Fisheries Resource Management (FRM), Faculty of Fisheries, SKUAST-K Laboratory for the estimation of total length, weight of fishes and weight of ovaries. Gravimetric and actual counting method was used for the estimation of fecundity. Result: It was observed that the number of eggs varied from 16650 (for a fish with total length 180mm and total weight 120 g) to 129000 (for a fish with total length 430 mm and total weight 1300 g. The mean absolute fecundity was recorded as 68864.07± 6563.59 for a fish with a mean total length of 301.43 ± 13.93 mm and mean total weight of 435.1 ± 66.51 g. The relative fecundity ranged from 99.2-240.8 and the mean relative fecundity was 185.96. Significant positive correlation was found between fish weight and absolute fecundity. (r= 0.907, p less than 0.01), fish length and absolute fecundity (r= 0.976, p less than 0.01), Ovary weight and absolute fecundity (r= 0.998, p less than 0.01). Relative fecundity showed a significant negative correlation with weight, length and absolute fecundity (r= -0.747, p less than 0.01; r= -0.419, p less than 0.05 and r= -0.460, p less than 0.05 respectively.

The aim of this study was to determine the distribution of parasites of the class Cestoda in farmed common carp from the cyprinid aquaculture facilities in Macedonia. The representatives of the class Cestoda occur most often during the winter (in 3.47% of examined fish), followed by spring (1.80%) and autumn (1.73%). They haven`t been identified during the summer. 20 fish out of 958 totally examined were infected with cestodes, with a mean intensity of 6.40, and a prevalence of 1.76%. In this study, the following parasite species were established: Caryophyllaeus fimbriceps, Bothriocephalus opsariichthydis and Ligula intestinalis (plerocercoid). Based on the total number of fish examined from cyprinid aquaculture facilities in Macedonia, the highest prevalence from the class Cestoda is determined by Bothriocephalus opsariichthydis (1.04%), followed by Caryophyllaeus fimbriceps and Ligula intestinalis with 0.55% each. The highest mean intensity with parasites of the class Cestoda is determined by Caryophyllaeus fimbriceps (9.40), followed by Bothriocephalus opsariichthydis (6.30) and Ligula intestinalis (3.60). The records of Caryophyllaeus fimbriceps in farmed common carp in the present study are considered as the first records for Macedonian aquaculture.
