During the period from November 2007 untill October 2008, a total of 255 specimens of the cyprinid fish Cyprinus carpio Linnaeus, 1758, were collected from fish markets east of Baghdad city. Microscopic examination of these fishes revealed that they were infected with five species of ciliated protozoans [Chilodonella cyprini with 1.6% percentage of infestation, Ichthyophthirius multifiliis (3.5%), Trichodina domerguei (21.6%), Apiosoma piscicola (0.4%) and Epistylis solidus (1.2%)]. C. carpio is considered as a new host (third host) in Iraq for Epistylis solidus

During the period from November 2007 till October 2008, a total of 255 specimens of the cyprinid fish, from freshwater fish Cyprinus carpio Linnaeus, 1758, were collected from fish markets east of Baghdad city. Microscopic examination of these fishes revealed that they were infected with two species of the crustaceans ]Argulus foliaceus (0.8%) and Ergasilus sieboldi (20%)[.The present study included the following: The clinical signs which were caused by the crustaceans, which included redness and an opacity of the skin, increase of mucus secretion and rapid movements of the operculum. The percentage incidence of the infection with these parasites were also found to be related to different length groups of the host, the larger fishes were more infected (95.2%) while the smaller fishes were less infected (0.8%).

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.

Dominance Level

The aim of this study is to inventory various types of ectoparasites found in koi fish that are reared in the nursery phase at the Sukabumi Freshwater Aquaculture Center (BPAT Sukabumi). Briefly, a total of 30 koi fish were taken randomly, then the scales, fins, and gills were examined and stained either with procedures of AgNO3. The type of parasite was identified and analyzed based on the rate of prevalence, also the intensity and dominance. The infesting parasite found were Trichodina sp, Oodinium sp, and Ichthyophthirius multifiliis. Overall, Trichodina sp is the most dominating parasite with a dominance level, prevalence, and intensity of 57,028%, 80%, and 10,833 respectively.

New Host Records

In order to contribute to the knowledge on helminth parasites of freshwater fishes in Mexico, the helminth fauna of the cyprinid fish Notropis moralesi was studied. The helminth species Bothriocephalus acheilognathi and Rhabdochona canadensis were recovered from 20 examined hosts. Values of prevalence, abundance and mean intensity of each infection are provided. Present work represents the first helminthological study for N. moralesi. Therefore, both helminth species recorded are new host records. This is the second report of B. acheilognathi and the first of R. canadensis for the state of Puebla.
