New Fish Species

In recent years and decades, two new fish species, the Caucasian dwarf goby (Knipowitschia caucasica) and the Amur sleeper (Perccottus glenii) have become members of the Hungarian fish fauna. In a 14-month study on the parasite fauna of these species, the authors detected 11 parasite species in the Caucasian dwarf goby and 17 species in the Amur sleeper. All parasites found in dwarf goby belong to species commonly occurring also in native Hungarian fishes, but three species (Goussia obstinata, Gyrodactylus perccotti and Nippotaenia mogurndae) collected from the Amur sleeper are introduced species new for the Hungarian fauna.

The article presents the results of hematological and parasitological studies of Amur sleeper Perccottus glenii of a small reservoir of artificial origin located in the vicinity of Perm. In this reservoir, Amur sleep-er is the only representative of the ichthyofauna. The collection of material was carried out in the spring-summer period of 2019. A total of 55 specimens of Amur sleeper were studied (30 specimens on May 8 and 25 specimens on July 12). Significant differences were found in the majority of quantitative indicators of fish blood cells in the spring and summer periods: in summer, the number of hematopoietic cells is higher (except for lymphocytes and monocytes), and in general, the content of mature leukocytes in the blood microliter in summer is lower. The parasite fauna of Amur sleeper in the studied reservoir is ex-tremely impoverished and is represented by the infusoria Trichodina nigra, cestode Nippotaenia mogurndae and nematodes, the latter were not recorded in Amur sleeper in this reservoir previously. The relationship between hematological parameters and the extent of parasite invasion was revealed: in more infected fish the number of immature erythrocytes, protoleukocytes, as well as neutrophils and eosinophils is significantly higher. The large numbers of Amur sleeper in the studied reservoir, the absence of devel-opmental anomalies in all the studied specimens, and the low proportion of fish with blood cell patholo-gies indicate the relative well-being of the studied part of the Amur sleeper population.

AbstractData on prevalence and current distribution of the cestode Nippotaenia mogurndae Yamaguti and Miyata, 1940 (Nippotaeniidea) in Slovakia, are provided. A total of 163 fish from 8 localities of different types in the Tisa River basin were infected with N. mogurndae. The mean intensity of infection was 1.8 with a maximum of 5 tapeworms. The expansion of the distribution of the cestode corresponds well with the spreading of its host, the invasive fish Amur sleeper Perccottus glenii Dybowski, 1877. The Spearmann correlation coefficient was used to test the relationship between the intensity of infection and standard length of the fish (r = 0.36; n = 163; P < 0.05), condition coefficient of the fish (r = 0.22; n = 115; P < 0.05) and season (r = −0.37; n = 355; P < 0.05). A significant correlation was confirmed for each pair of variables. There is a statistically significant difference between the prevalence of the cestode in two functional size groups (t = 3.28; n = 163; P < 0.05). The prevalence of the cestode increased with the standard length of fish. The potential risk of further expansion of N. mogurndae to other countries is discussed.

Abstract This first study investigated the crustacean parasite fauna in 66 species of fish from the Matapi River basin, state of Amapá (Brazil). Fish were collected every two months between March 2012 and August 2013, encompassing dry and rainy seasons. Among the 66 species examined (corresponding to 722 fish specimens) only 11 species were parasitized. The infestation prevalence was 2.2%, and a total of 48 specimens of parasites were distributed between three different parasite groups. These included Argulus elongatus, Dolops reperta and Argulus multicolor (Branchiura), Ergasilus xinguensis and Gamidactylus sp. (Copepoda), and Isopoda (Braga patagonica), but branchiuran species were predominant. This was the first report of these parasite species for Leporinus fasciatus, Astyanax bimaculatus, Curimata incompta, Pygocentrus nattereri, Crenicichla cincta, Crenicichla johanna, Geophagus camopiensis, Pterophyllum scalare, Plagioscion squamosissimus, Hypostomus plecostomus and Propimelodus eigenmanni. Lastly, this study expands the range of occurrence of these six parasite species to the Matapi River basin in eastern Amazon.

The paper aims to identify the age-related dynamics patterns of distributing the parasitofauna of ide in the Lower Irtysh. The composition of the ide parasitic community is represented by sixteen species belonging to the classes Monogenea, Cestoda, Trematoda, Nematoda, Copepoda, where Trematoda class is remarkable for the highest species diversity (9 species). It has been stated that the composition of the ide parasite fauna is distributed nonuniformly within the age groups. The study noted the presence of parasite species invading ide of any age group; there were also parasitic organisms observed either in young ide representatives, or in older fish species, as well as there were found parasite species not belonging to any distribution system. According to the analysis results of the age dynamics of the average invasion intensity, it has been found that the representatives of O. felineus and R. campanula prevailed in the number of specimens in all age groups of ide. The dynamics of the invasion extensity conditionally corresponds to three groups: EI growing with the fish aging, EI with a decreasing dynamics, constant EI = 100% (represented by R. campanula). The parasitofauna of the Lower Irtysh ide is similar to the parasite fauna of ide species inhabiting other water bodies, and shows the peculiarities of occurrence both within a separate age group and in the dynamics of occurrence parameters with fish aging

Abstract Non-indigenous parasite fauna of freshwater fish has not been studied extensively in Croatia, despite the long history of introductions and translocations of alien fish species into inland waters. Negative implications for aquaculture production and wild native fish species have been frequently associated with the introduction of non-native parasite species. Hence, the present paper attempts to lay out a historical overview of the suspected localities, time frames and pathways of introduction for non-indigenous fish parasites into inland waters of Croatia, therefore producing a list of species. In total, 16 non-native fish parasites have been recorded in inland waters of Croatia, aquaculture establishments being identified as initial points of introduction. However, a paucity of information exists on the overall prevalence of infection as well as the economic impact on aquaculture production. In addition, limited information is available about the presence and potential ecological impact of non-indigenous parasites on endemic fish fauna in areas of high biodiversity, such as the water bodies of the Adriatic Sea Basin. Therefore, there is an urgent need and opportunity for multidisciplinary cooperation between different stakeholders, including government, scientists, in both biological and veterinary disciplines, and the industry, with the aim of extensive surveys to determine the potential impact on aquaculture production and wild fish population of high conservation value.

AbstractMonogenean parasites of Amur sleeper Perccottus glenii introduced to Europe during the last century were studied during two seasons in the Wloclawski Reservoir (Poland). Introduction of a single species Gyrodactylus perccotti with its host was confirmed in both seasons: autumn 2006 and spring 2008. Occurrence of G. perccotti in Europe was reported for the first time. Intensity of infection decreased from 2006 to 2008, but the prevalence did not differ between the seasons. G. perccotti sampled in autumn 2006 showed low morphometrical variability and high morphological similarity with parasites collected in host native range, Amur River. In contrary, high morphological and metrical variability was found within the samples collected in spring 2008. Nucleic acid sequencing of the partial ITS rDNA confirmed that despite the variation in morphology or size of haptoral hard parts, all studied Gyrodactylus specimens belonged to the same species (G. percotti) and no intraspecific variation was detected.

AbstractOne of the fish species with the highest potential for aquaculture is the sharpsnout seabream, Diplodus puntazzo Cetti. Among other aspects, the development of new fish cultures requires studies of potential pathogens that may compromise survival of the fish in captivity. Moreover, both cultured and wild fish can act as sources or reservoirs of pathogens which may negatively affect other well-established cultures. We have studied the parasite fauna of the wild sharpsnout seabream, and monitored the survival of the parasites in culture conditions. The sharpsnout seabream was sampled from two different Spanish localities and examined for parasites. Additionally, 20 fish were maintained in captivity. Ten of them were examined for parasites after a period of 10 days and a further ten fish after another 10 days. All fish were parasitized with at least four species, with 19 parasite species being identified, seven of which were recorded for the first time in the sharpsnout seabream. These included Microcotyle sp., Magnibursatus bartolii, Steringotrema pagelli, Galactosomum sp., Cardiocephaloides longicollis, Caligus ligusticus and Gnathia vorax. We also report the first records of two parasite species in the wild sharpsnout seabream, the polyopisthocotylean monogeneans Atrispinum seminalis and Sparicotyle chrysophrii. Previously, these parasites had only been recorded in farmed sharpsnout seabream. Most parasites in the skin, gills and alimentary tract disappeared under the conditions of captivity, with the exception of the monogeneans of the genus Lamellodiscus. The information provided about the sharpsnout seabream parasite fauna will be useful to prevent possible problems in fish farms due to some parasite species. Many parasites of the sharpsnout seabream recorded in the present study are shared by the main fish species in Mediterranean aquaculture, the gilthead seabream, thus suggesting the possibility of cross-infections.
