Aquatic fungi growing on eel fry montée Anguilla anguilla L
Acta Ichthyologica et Piscatoria
Abstract
In the spring 1987, the author investigated of the mycoflora on the eel fry montée (Anguilla anguilla L.) and their environment in Mikołajskie Lake.
... Significant variations between electrical conductivity and aquatic fungi investigated.The richest occurrence of aquatic fungi relatively seen in the water samples which characterized with low total dissolved similar results reported in Saudia Arabia [33], in Egypt [34] and in Poland [35]. Dissolved oxygen also play an important role in the population of aquatic fungi in Egypt [9] in Poland [36,37] and in Baghdad [17], depletion in dissolved oxygen may be due to increasing of water temperature [38] or due to oxidative and fermentative degradation of organic mater drained with sewage [39]. BOD 5 is used for determination of biological oxygen demand. ...
... Mycotic infections were also studied in cultured populations of the Japanese eel (Hoshina and Ookubo 1956;Egusa and Nishikawa 1965;Inman and Bland 1981) and of the European eel (Copland and Willoughby 1982;Willoughby and Copland 1984). Czeczuga (1994) found the growth of Saprolegnia ferax 7 Saprolegnia monoica, and Candida albicans on montee fry in natural conditions of Mikołajki Lake. ...
The authors investigated the mycoflora developing on the dead glass eel (montee) and elvers (Anguilla anguilla L.).
... Czeczuga and Muszyńska (1994) observed its growth on other keratin-containing substrates. It is a common fungus in northeastern Poland (Czeczuga 1995 (Scott and O'Bier 1962;Florynskaya 1969Florynskaya , 1971Srivastava and Srivastava 1976;Smith et al. 1985;Lartseva 1986;Lartseva and Altufiev 1987;Osipian et al. 1988;Lartseva and Dudka 1990;Czeczuga 1994b;Czeczuga and Muszyńska 1999). Those found on the body of various species were: Saprolegnia australis (cf. ...
The authors investigated of the mycoflora developing on the eggs of fishes representing 33 cyprinid taxa.
... Saprolegnia ferax, S. diclina and S. parasitica are known to be pathogens to cold water fishes. Any species of fish that are intensively cultured and captured are at risk of suffering fungal diseases (Czeczuga, 1994;Blazer et al., 2002). Among them, Saprolegnia ferax and S. parasitica are the most dangerous, causing the death of whole populations of many fish species in certain water basing as is the case of breeding populations of Pacific salmon (Czeczuga and Muszyńska, 1996) and the Atlantic salmon Salmo salar in Great Britain and Poland (Stuart and Fuller, 1968;Czeczuga et al., 2011). ...
Investigations of occurrence of Saprolegnia diclina from four limnocrenic springs of rivers within the Białystok where eggs of Carassius carassius were the bait were done. Identification of isolates was accomplished on the basis of their vegetative, asexual reproduction, generative organs and by studying the sequencing of the internal transcribed spacer of nuclear ribosomal DNA (ITS1+5.8S+ITS2). S. diclina occurred in 29 (60.4%) [10(20.1%) in spring, 4 (8.3%) in summer, 11 (23.0%) in autumn and 4 (8.3%) in winter, 2005] of the 48 examined water samples. The results indicate the sequence comparisons of two ITS nuclear DNA for species identification: S. diclina. The results indicate that the sequence of our isolate correspond to S. diclina. It is very important that this study represents the first isolation (on the basis of molecular features) of S. diclina in fresh waters in Poland.

... The greatest losses on fish farms, however, are due to Saprolegnia species [9,23,25,49]. Among them, Saprolegnia ferax and Saprolegnia parasitica are the most dangerous, causing the death of whole populations of many fish species in certain water basins, e.g. the Atlantic salmon Salmo salar in Great Britain [46] or breeding populations of the Pacific salmon [15]. ...
The authors investigated the growth of hydromycoflora on the eggs of Carassius carassius in spring water (oligotrophic) and river water (eutrophic). Forty fungus species were found, including 37 in spring and 21 in river water. Some fungus species appeared new to fish and to Polish hydromycoflora.

In dieser Arbeit wurde das Vorkommen aquatischer Saprolegniales und Leptomitales im Auesee und in der Fulda in Kassel (Hessen) unter besonderer Berücksichtigung der fischpathogenen Arten untersucht. Von Juli 2003 bis Juni 2004 wurden hierzu monatlich Wasserproben entnommen und, unter Verwendung der Ködermethode, hinsichtlich des spezifischen Vorkommens aquatischer Oomycetes-Arten zu bestimmten Jahreszeiten untersucht. Manche Arten wiesen saisonale Spezifitäten auf. 9 von 11 Arten der aus den Gewässern isolierten Saprolegniales und Leptomitus lacteus (Roth) C. Agardh, eine der beiden isolierten Arten der Leptomitales, sind nach Literaturangaben bei Fischen nachgewiesen. Außerdem traten 7 von 10 Arten nach Literaturangaben bereits an Fischarten der beiden Gewässer auf. Während der Probenahme zur Gewinnung aquatischer Oomycetes-Arten erfolgte eine zeitgleiche limnologisch-chemische Untersuchung der Gewässer. Die Ergebnisse einiger Messwerte der Fulda wurden zudem mit den vorgegebenen Richt- bzw. Grenzwerten eines Fischgewässers der „Cyprinidenregion” verglichen.
Mycoflora developing on some fish species, recently introduced to Polish waters, has not been known. The authors incubated muscles of four fish species (monkey goby, Neogobius fluviatilis; racer goby, N. gymnotrachelus; Chinese sleeper, Perccottus glenii; and stone moroko, Pseudorasbora parva caught in the drainage area of the Bug River) in water taken from 6 different places. A total of 59 fungus species were found to grow on fish muscles studied: Achlya ambisexualis, A. americana, A. caroliniana, A. crenulata, A. debaryana, A. diffusa, A. dubia, A. intricata, A. klebsiana, A. oblongata, A. oligacantha, A. orion, A. polyandra, A. prolifera, A. proliferoides, A. radioasa, A. rodrigueziana, A. treleaseana, Aphanomyces irregularis, A. stellatus, Blastocladiella britannica, Blastocladiopsis parva, Catenaria verrucasa, Cladolegnia unispora, Dictyuchus monosporus, Isoachlya monilifera, Leptolegnia caudata, Leptomitus lacteus, Phlyctochytrium aureliae, Pythium afertile, P. aquatile, P. arrhenomanes, P. butleri, P. dissotocum, P. hemmianum, P. intermedium, P. myriotylum, P. ostracodes, P. periplocum, P. tenue, Rheosporangium aphamidermatus, Rhizophlyctis hirsutus, Rhizophydium laterale, R. macrosporum, Saprolegnia asterophora, S. diclina, S. eccentrica, S. ferax, S. hypogyna, S. litoralis, S. mixta, S. monoica, S. parasitica, S. pseudocrustosa, S. shikotsuensis, S. torulosa, S. uliginosa, Thraustotheca clavata, Zoophagus insidians. The results obtained may be important to ichthyopathologists, because 25 of the above-mentioned fungi are known as necrotroph or parasites of fishes.
Studies on the occurrence of aquatic fungi in the bathing sites of the river Supraśl in Podlasie Province of northeastern Poland were conducted in the years 2001-2003. Some hydrochemical analyses were performed using standard methods. Bait method was used to isolate the fungi. Th e following species were identifi ed: fi sh pathogenic fungi – Achlya orion, Aphanomyces laevis, Dictyuchus monosporus, Saprolegnia ferax, S. monoica, and S. parasitica; human pathogenic fungi – Aspergillus candidus, Candida albicans, Lagenidiu m humanum, Penicillium mycetomagenum, Rhizophydium keratinophilum, and Trichosporon cutaneum; and phytopathogenic fungi – Achlya racemosa, Pythium butleri, P. myriotylum, and P. debaryanum. Physicochemical parameters of water in the bathing sites had no important eff ect on the presence of fungi.
