“…Dactylogyrus has eye spots between 2 and 4, a pair of large anchor hooks, and a layer of eggs (Klinger and Floyd 2016). Commonly, Monogenea is parasites which cause a big economical problem due to it can injure the skin or gills of cultured fish (Borji et al 2012). …”

Abstract. Saptiani G, Pebrianto CA, Agustina, Hardi EH, Ardhani F. 2017. Short Communication: Diversity and prevalence of ectoparasites associated with cultured fish from coal ponds in East Kalimantan,. In East Kalimantan, coal pits are used for fish culture. The most fish species cultured in the coal ponds were carp and tilapia. The study aimed to identify ectoparasites types, diversity, and prevalence of fish cultured in coal ponds. Sampling was carried out between January and March 2016 on coal ponds in Kutai Kartanegara District, East Kalimantan. Samples were taken from two different coal ponds, but both coal ponds cultivated the same species of fish samples (carp and tilapia). The number of fish samples taken from coal ponds was 40 samples for each fish types in each location of coal ponds with the body weight of the fish samples between, 20-30 g. The preparation of parasite identification was conducted by taking every fish's external organ which was then scraped for microscopical preparation and observation. The identification of parasites was determined based on the morphological characteristics including the shape performances, specific spots and also the type of environment and habitat. The results showed that ectoparasites found in carp and tilapia cultured in coal ponds were Ichtyopthirius multifilis, Trichodina, Oodonium, Dactylogyrus, and Gyrodactylus, while Epistylis was only found in carp. The average percentage of ectoparasites prevalence in carp was from 30.00 to 59.17% with the attacked intensity was between 2.47 to 4.43 parasites/fish, while in tilapia was from 27.5 to 40.83% with the attacked intensity between 1.04 to 2.83 parasites/fish. The highest prevalence and intensity of parasite attacks was Trichodina in carp from a pond which has been used for a long time for fish culture. The prevalence and attacked intensity of ectoparasites on fish were higher in the longer use of coal ponds rather than those in new ponds.

“…These noxae may induce tissue alterations, which affect the physiological function of the gills, such as respiration, ammonia excretion or maintenance of the osmotic balance. In carp, gill diseases were associated with adverse water quality, including elevated pH and ammonia levels (Raskovic, Poleksic, Zivic, & Spasic, ), parasitic infections, such as gill flukes (Borji, Naghibi, Nasiri, & Ahmadi, ), Ichthyobodo or Dermocystidium (Červinka, Vítovec, Lom, Hoška, & Kubů, ), as well as bacterial infections, mainly by flavobacteria (Farkas & Oláh, ; Swain et al., ). In Atlantic salmon ( Salmo salar ), gill diseases were recently recognized as being multifactorial.…”

Koi sleepy disease (KSD) is a disease with increasing importance in global common carp aquaculture. Despite the fact that carp edema virus (CEV) is most likely the causative agent of KSD, the disease often presents itself as multifactorial with several parasites and bacteria species present on gills, skin or in internal organs. Therefore, in this study, we analysed and presented initial results on an interaction of flavobacteria and CEV in the development of clinical KSD in carp suffering from proliferative gill disease. We examined selected field samples from Germany and Hungary and confirmed the presence of CEV and flavobacteria co-infections in subset of the samples. In several infection experiments, we studied the transfer and dynamics of both infections. Furthermore, we analysed which Flavobacterium species could be isolated from KSD-affected fish and concluded that Flavobacterium branchiophilum is a possible copathogen. Antibiotic treatment experiments showed that CEV seems to be the primary pathogen causing an insult to the gills of carp and by these enabling other pathogens, including F. branchiophilum, to establish co-infections. Despite the fact that F. branchiophilum co-infection is not required for the development of clinical KSD, it could contribute to the pathological changes recorded during the outbreaks.

“…Previously, single molecular markers, such as partial mitochondrial rrnS, cox1 and nad2 genes, 18S and 28S rDNA genes, and internal transcribed spacer (ITS 1 and 2) of the rRNA gene, have been used to study the Dactylogyridae family. These studies focused mainly on the phylogeography (Wang et al, 2014), species identification (Borji et al, 2012), co-speciation in host-parasite assemblages (Šimková et al, 2004) and phylogeny of the Dactylogyridae (Šimková et al, 2006). Regarding the phylogeny, poly-and/or paraphyly of the 'catch-all' Ancyrocephalidae family (or Ancyrocephalinae subfamily) have been widely discussed (Šimková et al, 2003Mendoza-Palmero et al, 2015).…”

Despite the worldwide distribution and pathogenicity of monogenean parasites belonging to the largest helminth genus, Dactylogyrus, there are no complete Dactylogyrinae (subfamily) mitogenomes published to date. In order to fill this knowledge gap, we have sequenced and characterized the complete mitogenome of Dactylogyrus lamellatus, a common parasite on the gills of grass carp (Ctenopharyngodon idella). The circular mitogenome is 15,187 bp in size, containing the standard 22 tRNA genes, 2 rRNA genes, 12 protein-encoding genes and a long non-coding region (NCR). There are two highly repetitive regions in the NCR. We have used concatenated nucleotide sequences of all 36 genes to perform the phylogenetic analysis using Bayesian inference and maximum likelihood approaches. As expected, the two dactylogyrids, D. lamellatus (Dactylogyrinae) and Tetrancistrum nebulosi (Ancyrocephalinae), were closely related to each other. These two formed a sister group with Capsalidae, and this cluster finally formed a further sister group with Gyrodactylidae. Phylogenetic affinity between Dactylogyrinae and Ancyrocephalinae was further confirmed by the similarity in their gene arrangement. The sequencing of the first Dactylogyrinae, along with a more suitable selection of outgroups, has enabled us to infer a much better phylogenetic resolution than recent mitogenomic studies. However, as many lineages of the class Monogenea remain underrepresented or not represented at all, a much larger number of mitogenome sequences will have to be available in order to infer the evolutionary relationships among the monogeneans fully, and with certainty.
