Abstract:

L’étude de la parasitofaune branchiale de 558 Barbus martorelli a été menée dans un cours d’eau douce aux alentours de Yaoundé (Cameroun) en milieu tropical, afin d’obtenir des informations sur la répartition des agents pathogènes dans une population d’hôtes sauvages ; ces données sont indispensables dans la recherche de moyens pour éviter les pertes énormes souvent observées en pisciculture intensive. Cette analyse a révélé la présence de deux espèces de myxosporidies (Myxobolus barbi et M. njinei) et de huit espèces de monogènes (Dactylogyrus bopeleti, D. insolitus, D. simplex, D. maillardi, Dogielius martorellii, Dogielius sp., une espèce de Gyrodactylidae et une larve de Polystomatidae). Quatre poissons n’ont pas présenté de parasites, 24 ont présenté une infection monospécifique et 530 une infection plurispécifique. Chaque individu infesté a hébergé en moyenne quatre espèces de parasites. Alors que la prévalence et l’intensité moyenne parasitaire diminuaient avec la taille de l’hôte pour les protozoaires, le phénomène inverse a été observé pour les helminthes. L’effet sexe a été noté dans l’infestation de B. martorelli par la myxosporidie M. njinei et par la plupart des espèces de monogènes. Les femelles ont ainsi été plus infestées que les mâles en raison de leur biologie en période de frai. Enfin, la richesse des espèces parasitaires a semblé affecter négativement le poids des hôtes.

Abstract:

Mullets (Mugilidae) are economically-important fish exploited extensively by artisanal fisheries on the Amazon coast of Brazil. In the present study, 150 specimens of redeye mullet (Mugil rubrioculus) acquired from the public fish market were examined, and the gill filaments of 90 (60%) were found to be infected with spores of Myxobolus. The mature spores were spherical, with a mean diameter of 6.28±0.33 μm, and had polar capsules of equal size (2.47±0.34 μm in length and 1.58±0.27 μm in width). The 18S rRNA sequence of the parasite was compared with those of other myxosporidian species available in the GenBank database. The morphological and molecular characteristics of the parasite indicate strongly the existence of a new species, denominated Myxobolus bragantinus n. sp., the first case of a new myxosporidian species to be found in this host.

Abstract:

Oreochromis niloticus, being one of the most commonly cultured fish on earth constitutes a favorable biotope for myxosporidia. This study provides information concerning the prevalence and mean intensity of Myxobolus species recorded in the kidney and spleen of O. niloticus. O. niloticus were sampled in farming ponds at Bamendou in Cameroon. Classic methods concerning fishing, fish autopsy and search of Myxosporidia were used. Prevalence and mean intensity was calculated. Data analysis based on the chi-square test, Kruskal-Wallis H test and Mann-Whitney U test was done. The study revealed the presence of six Myxobolus species in the kidney and spleen of O. niloticus. All parasites species appeared frequent while their mean intensity was low or very low. The occurrence of M. fotoi was statistically lower (P < 0.05) in the kidney’s anterior portion while the mean intensity of M. agolus was statistically (P < 0.01) higher in the anterior portion of the spleen. Myxobolus cichlidarum was not found in kidney of young fish and occurrence of M. agolus statistically increases (P < 0.05) with host age. Host sex has significant influence (P < 0.05) on: occurrence of M. agolus, M. fotoi, M. agolus, M. brachysporus and M. heterosporus; and mean intensity of M. fotoi. The study revealed that in O. niloticus, the kidney and spleen harboured the same parasites species and there were only few variations in occurrences and mean intensities of parasites species recorded as function of host organs, age and sex.

Abstract:

The article presents the results of studies of nutritional value and the degree of infection with parasitoses of Siberian vendace (Coregonus sardinella Vallenciennes, 1848) and Yakut crucian carp (Carassius carassius jacuticus Kirillov, 1972). By the amount of protein, the Siberian vendace is classified as medium-protein, in terms of fat content, it is especially fatty fish and of high calories. It has been established that a distinctive feature of the Yakut crucian carps compared to European ones is high fat content (up to 10 % versus 2.5 %), high content of polyunsaturated fatty acids, macro- and microelements, vitamins, and have high energy value. The most common parasitic diseases of the crucian carp and vendace, affecting the quality and appearance of the fish, are myxosporidioses caused by Myxobolus, digramosis and phylometroidosis, the negative impact on the quality of which depends on the parasite infection intensity.

ABSTRACT This study describes aspects of infections caused by the myxosporidian Kudoa orbicularis in filter-feeding cichlids, Chaetobranchopsis orbicularis, caught in the Arari River in the municipality of Cachoeira do Arari, on Marajó Island, Pará, Brazil. The parasite forms pseudocysts scattered throughout the striated epaxial and hypaxial muscles. Samples embedded in paraffin were analyzed histologically using hematoxylin-eosin, Gömöri, Ziehl-Neelsen, and Giemsa staining. Necropsy of the C. orbicularis specimens revealed that 100% (50/50) were infected with K. orbicularis. The specimens presented grossly abnormal muscle texture, resulting in extensive inconsistencies and weakness. Progressive softening of the muscles was observed during necropsy, indicating the rapid enzymatic autolysis of the tissue. The parasite found in the muscle tissue of C. orbicularis was identified as K. orbicularis, with clinical signs of disease being observed in the fish. The necropsy revealed extensive damage to the host organism, with well-established fibrocystic infections in the muscle fibers, associated with post mortem myoliquefaction.

Abstract:

Six myxosporidian species were found in chub (Leuciscus cephalus) originating from Lower Austrian rivers. The frequency of the parasites and their localization was recorded. In all chub, independent of size and origin, Myxobolus cyprini occurred predominantly in the macrophage centres (MCs) of the haematopoietic organs, spleen and kidney. Exclusively in the head kidney of young fish not yet described vermicular plasmodia containing spores of M. cyprini were found. In muscle tissue the prevalence of M. cyprini was comparatively low. Other species of Myxobolus characterized by plasmodial cysts frequently occurred in gills and swimbladder but were rarely detected, and only in small numbers, in the haematopoietic organs. The number of M. cyprini spores and the relative volume of MCs in the haematopoietic organs were estimated in order to examine possible correlations. Significant interrelated changes were found only in juvenile fish up to a size of 15cm. In bigger fish, the number and size of macrophage aggregates were highly variable and independent of infection intensity and fish size, but the number of spores never exceeded that of the aggregated macrophages. The data suggest that due to an early date of infection M. cyprini is the only species which is closely associated with macrophage aggregation.

Abstract:

Samples of different organs from intensively-reared Piaractus mesopotamicus were collected and processed using routine histological techniques in order to produce thin sections for staining with hematoxylin-eosin and with the Ziehl-Neelsen method. Through examination under an optical microscope, myxosporidians of the genera Henneguya sp. and Myxobolus sp. were identified, respectivelyin the gills and kidneys of P. mesopotamicus. Plasmodia with immature spores of Henneguya sp. were located along the secondary lamellae, with total length of 30.45±4.84µm and width of 3.52±0.33µm. Spores of Myxobolus sp. were located in the kidneys, with total length of 8.94±0.82µm and width of 5.59±0.39µm. Histopathological analysis of the gills showed plasmodia containing spores of Henneguya sp., at intralamellar and intravascular localities, at different stages of development. Spores of Myxobolus sp. were identified in the kidneys, in the peritubular region and in the interstices and glomerulus, surrounded by melanomacrophages. Focal hemorrhage was recorded in a few cases. Ziehl-Neelsen staining allowed to identify particular features of the spores and facilitated biometry and enabled classification in comparison with hematoxylin-eosin, thus demonstrating its usefulness for histopathological diagnosis of the parasitosis.

Abstract:

The aim of this study was to evaluate the prevalence and seasonal distribution of the main parasite species in Amazonian ornamental cichlids that affect their trade. The study was conducted from August 2007 to September 2009. We sampled 3042 specimens from 9 different species, of which 9.47% had at least one type of external parasite. 81.25% of the cases occurred in the dry season. Crenicichla anthurus (28.57%) was the most parasitized, followed by Aequidens diadema (26.32%), Pterophyllum scalare (22.69%), Cichlasoma sp. (9.52%), Apistogramma sp. (3.88%) and Symphysodon aequifasciatus (3.66%). Monogenea was the most abundant group of parasites, occurring in 66.67% of the cases, of which 96.88% occurred in the dry season. This parasite infested 95.68% of Pterophyllum scalare, 76.67% of Apistogramma sp, 33.33% of Cichlasoma sp. and 23.81% of Symphysodon aequifasciatus cases. Ichthyophthirius multifiliis infested 100% of Aequidens diadema, 76.19% of Symphysodon aequifasciatus, 66.67% of Cichlasoma sp, 41.67% of Crenicichla anthurus and 23.33% of Apistogramma sp cases. Myxosporidia infested 58.33% of Crenicichla anthurus. Trichodina infested 4.32% of Pterophyllum scalare. The prevalence of these parasites is related to the season, preferred habitat, fish behavior, individual susceptibility and handling of animals during transportation by fishermen.

Abstract:

Abstract Histology is science that learns about cell,organ, and body tissues in a microscopic condition. Whereas science that learns about morbidity or patology of a tissue that’s called as histopatology. Both of normal tissue’s structure and abnormal tissue’s stucturecan be learned by microscopic in a tissue preparation. This preparation made through processing of tissue until the preparation coloured. Then histology’s structure can be watched clearly so that make it easy to read. Field Work Practice purpose (PKL) this is to know the basic histoloy technique in fish. This Field Work Practice was held in Balai Uji Standar Karantina Ikan Pengendalian Mutu dan Keamanan Hasil Perikanan (BUSKIPM) Jl. Harapan I No. 01A Cilangkap, East Jakarta on 14th January 2013 until 14th February 2013. The method of this Field Work Practice is descriptive method by collecting data through primary data and secondary data. The histology technique in fish are tissue fixation, trimming (tissue selection), tissue dehydration, the tissue block making, tissue cutting, tissue colouring, and tissue observation.

Abstract:

The article gives the analysis of infestation of Siberian sterlet Acipenser ruthenus marsiglii by parasites in the Lower Irtysh within 2017 to 2019. The annual changes in the species composition of parasites and in quantitative indicators of the fish infestation were revealed. In 2017 there were found 10 species of parasites, of which 4 were specific: Trypanoplasma acipenseris, Haemogregarina acipenseris, Acrolichanus auriculatum, Capillospirura ovotrichuria; in 2018 - 11 species, of which 6 were specific: T. acipenseris, H. acipenseris, Sphaerospora colomani, A. auriculatum, Truttaedacnitis clitellarius, Capillospirura itrichura; in 2019 - 7 species of parasites, of which 4 were specific: T. acipenseris, H. acipenseris, S. colomani, A. auriculatum. Of the broadly specific parasites, 6 species have been recorded: Trichodina acuta, Trichodina nigra, Trichodina sp., Diplostomum chromatophorum, Piscicola geometra, Unionidae gen. sp. In Siberian starlet blood there were registered T. acipenseris and H. acipenseris in all years of research. An increased extensiveness of invasion by these parasites was established. A significant decrease in infection with A. auriculatum trematode was found. The nematode C. ovotrichuria was recorded in sterlet only in 2017 and 2018. High values of infestation with Trichodina acuta, Trichodina nigra, Trichodina sp.were recorded. Myxosporidium Sphaerospora colomani was first recorded in the Ob-Irtysh basin. It has been suggested that the annual changes in the species composition of sterlet parasites are associated with the direct impact of the temperature regime and fluctuations in the level of the Irtysh basin

Abstract:

Fisheries research was carried out on the Khantayskoye reservoir in 1977–2020. This article presents the results of these works. In the first years after the flooding of the Khantayskoye reservoir, pike and common species of whitefishes (Siberian vendace, peled and whitefishpyzhyan) constituted the basis of the fishery. The share of other fish (carp, burbot, perch) was insignificant. The sharp increase in the food supply for planktophages and benthophages was short-term. Trophic depression began to appear in the early 80s (3–5 years from the moment the reservoir was filled). From this moment to the present time, whitefish species have a slowdown in linear and weight growth, an increase in the timing of puberty, a decrease in fertility. Of the whitefish fish, only Siberian vendace and whitefish are present in the fishery, the numbers of which have significantly decreased. Since the mid-2000s, the number of peled has decreased significantly and this species of fish has become rare in the reservoir. . Currently, there is a relatively high number of pike. Roach, ide, pike and perch actively mastered the channel of Kontiki, where before was practically absent. The increased number of these species affects the number of whitefish in their spawning areas, and their reproduction, including the safety of eggs.The parasite fauna of the main commercial fish species of the Khantayskoye reservoir was investigated. The most pathogenic were myxosporidia Henneguya zschokkei (Gurley, 1894), the causative agent of peptic ulcer disease in whitefishes.

Abstract:

One of the predators of the ichthyofauna of the Lower Tobol is Esox lucius (Linnaeus, 1758) (Esociformes, Esocidae). The purpose of this work is to study the current state of the E. lucius parasite fauna in the lower reaches of the Tobol River. In the present study 47 individuals of the northern pike of different sex aged from 2+ to 8+ years were examined by the method of complete parasitological dissection. As a result of the research, 23 types of parasites were found in the pike. The largest number of species of parasitic organisms – 20 – were found in May, 12 were found in December and 11 in September. Of these, 10 species are specific to northern pike: Haemogregarina esoci (Nawrotzky, 1914), Chloromyxum esocinum (Dogiel, 1934), Myxidium lieberkuhni (Biitschli, 1882), Myxosoma anurum (Cohn, 1895), Henneguya psorospermica (Thelohan, 1995), Tetraonchus monenteron (Wagener, 1857), Gyrodactylus lucii (Kulakowskaja, 1951), Triaenophorus nodulosus (Pallas, 1781), Azygia lucii (Miiller, 1776), Raphidascaris acus (Bloch, 1779). For the first time an intraerythrocyte parasite – H. esoci – was found in pike in the Lower Tobol, the extensiveness of invasion was 18.7% in December, and 6.2% in May. Epistylis sp. and Trichodinella epizzotica parasitized on the surface of the body of fish only in May, whereas members of the genus Trichodina were found in winter and spring. In all seasons, parasitization by M. anurum and H. psorospermica was established on the gills. The greatest occurrence of spores of M. lieberkuhni and C. esocinum was observed in the spring. Myxosporidia parasitized in the kidneys and T. monenteron parasitized on the gills during all periods of the study (the latter with an extensivity of invasion of 100.0%). All examined fish are infected with T. nodulosus 100.0% of cases. In May, other types of cestodes were found: P. esocis and Dibothriocephalus latus. Three pike were infected with proteocephalis. The larval stage of diphyllobothriid was found in one fish in the liver and gonads in an amount of 139 individuals. In the pikes’ stomach, during all periods of the study, A. lucii was found in all the fish examined. In the autumn period of the study immature R. campanula were found in in the intestine of 4 fish specimens. The nematode R. acus was found in pike only in spring. This nematode was found in fish aged 4+–8+. In May, glochidia with a high intensity of invasion were found on fins, gill covers and gills of fish. E. sieboldi copepods were found on the gills; in May, one specimen was found in one pike and in September in 6 with AI of 0.7. Tetraonchus monenteron was a dominant species, in May its degree of dominance decreased with the greatest uniformity of species in this study period. Having considered the age dynamics of pike infection by various types of parasites, it was found that in the age group 4+–5+ the number of species of parasites was greatest (20), while in groups 2+–3+ and 6+–8+ it was 14. In the pike, the core parasitic fauna were M. anurum, H. psorospermica, T. monenteron, T. nodulosus, A. lucii. Seasonality has virtually no effect on the degree of infection with specific parasites. The age of fish largely determines the qualitative and quantitative composition of the parasite fauna.

Abstract:

AbstractThe garpike Belone belone (L.) is an epipelagic fish abundant in the Mediterranean, parasitized by two coelozoic myxosporidians in the gall bladder — Myxidium sphaericum Thélohan, 1895 and Ceratomyxa beloneae Lubat, Radujković, Marques et Bouix, 1989. In order to redescribe these intriguing and taxonomically complex species, whose original descriptions are limited only to line drawings based on light microscopy, we studied the morphology and ultrastructure of their vegetative and sporogenic stages. M. sphaericum has an oval to sigmoid or mild crescent shape in the frontal view, large conical polar capsules, opening at the spore end, in opposite direction of the spore length, with 8–9 coils of polar filament. C. beloneae has elongated and slightly arched valves; symmetrical and smooth, with the posterior surface almost straight and anterior surface mildly inclinated, having 5 coils of the polar filament.
