Opis:
A new species of Ergasilus von Nordmann, 1832 (Copepoda: Ergasilidae) parasitic on the gills of two gobiid fishes Boleophthalmus dussumieri Valenciennes and Bathygobius fuscus (Rüppell, 1930) from Shatt Al-Basrah Canal, Iraq, is described. The new species differs from all its congeners by a combination of character states including the shape of the body, and the structure and armature of the swimming legs.

Opis:
European perch (Perca fluviatilis) is a widespread species of freshwater fish. The most frequently isolated parasites in this species are endoparasites, such as trematodes, cestodes and nematodes. The purpose of the study was to determine the presence of parasite species found in perch and the correlations between the occurrence of parasites and age in fish from the Lake Góreckie reserve, located in Wielkopolski National Park. Among 139 examined perch, parasites were found in 69,8%. The analysis showed parasite species from the genera Acanthocephalus, Cammallanus, Neoechinorhynchus, Triaenophorus, Proteocephalus and Tetracotylus. The most common parasitosis was taeniasis. The analyses showed that occurrence of parasites correlates with the age of perch. Older fish were more often infected with parasites, especially of the genus Triaenophorus.

Opis:
Ultrastructural analyses of fish-infecting myxosporean Henneguya piaractus that is found in the gill lamellae of the freshwater teleost Piaractus mesopotamicus (Characidae) and collected from the Paraguai River, Brazil were described. The parasite occurs within large whitish spherical to ellipsoidal polysporic cysts (up to 2.5 mm long) delimited by a layer of fibroblasts generally connected with some capillaries on the gill epithelium. No external morphological signs of disease were visible in the infected fishes. The tailed spores measured 61.5 ± 0.91 (60.2–62.6) μm in total length and ellipsoidal spore body 21.1 ± 0.62 (20.6–21.9) μm long, 6.7 ± 0.40 (6.2–7.3) μm wide and 2.5 ± 0.54 (2.0–3.1) μm thick. The spore wall was about 97 nm of thickness and consisted of a thin electron-dense exospore and a thick electron-lucent endospore with about 85 nm of thickness. The tailed spores were composed of two equal–sized shell valves adhering together along the straight suture line each having in continuity a equal caudal tapering tail measuring 40.5 ± 1.02 (38.7–43.1) μm in length. Two symmetric polar capsules measured 9.8 ± 0.28 (9.3–10.1) μm long and 1.9 ± 0.37 (1.4–2.4) μm wide, each having a polar filament with 10–11 (rarely 12) coils

Opis:
This study used light and electron microscopy to describe a myxosporean, polysporic, histozoic plasmodium infecting the gill filaments of the freshwater teleost, Semaprochilodus insignis, specimens of which were collected from the Trombetas River (Central Amazonian Region, Brazil). Ultrastructural analyses of the fish-infecting spores identified the parasite as Myxobolus insignis, an organism that occurs within whitish unequal-sized plasmodia located in the intralamellar epithelium of the gill. Based on the observed morphological and ultrastructural features of the plasmodia in this study three stages in the plasmodial evolution were distinguished, related to the sporogonic stages of Myxobolus insignis. The plasmodium walls were also found to constitute a number of layers of fibroblasts, surrounded by collagen fibres, which displayed different morphological arrangements according to the different phases of evolution. This represents the first time such ultrastructural features have been described in detail for Myxobolus insignis plasmodia and offers potentially significant points of comparison with plasmodia from other species of myxosporea.

Opis:
There has hitherto been very few research projects focusing on ectoparasites of Antarctic fishes. The presently reported study provides data on the prevalence and the intensity of leeches (Hirudinida: Piscicolidae) infecting fishes. The materials were collected in December–February 1986/87 off the Elephant Island, South Georgia, Joinville Island, and South Shetlands. The following leech taxa were recorded in the Antarctic fishes of the family Channichthyidae: Trulliobdella capitis (Brinkmann, 1947); Cryobdella antarctica Epstein, 1970; Nototheniobdella sawyeri Utevsky, 1997; and Cryobdella sp. The above findings constitute new geographic records from off Elephant and Joinville Island and South Georgia.

Opis:
The paiche, Arapaima gigas represents a socio-economically important species in the Peruvian Amazon, and actually an intensive production for human consumption has emerged during the last years. Therefore, more studies are required in fish farming development, especially concerning populations of parasites that affect fish production yields. Eighty specimens of paiche collected between September and October of 2011 from semi-intensive fish farm in Loreto State, Peru, were examined for their helminthic parasites. Five species were recorded parasitizing A. gigas: Dawestrema cycloancistrium and Dawestrema cycloancistrioides (Monogenea) on gills, Trichodina sp. (Protozoa) on the skin, Caballerotrema arapaimense (Trematoda) in stomachs and Philometra senticosa (Nematoda) in the swim bladder. Highest prevalence was recorded for D. cycloancistrium (100.0%), D. cycloancistrioides (83.0%) and Trichodina sp. (50.0%) and highest values of mean intensity and mean abundance were recorded for D. cycloancistrium (260) parasites per individual. The results confirm the necessity of constant monitoring of fish, seeking the diagnosis and timely control of infestations with parasites, in order to eradicate the mortality of the host that leads unviable the fish farming intended for human consumption.

Opis:
The monogenean ectoparasite genera Dactylogyrus and Gyrodactylus are hyperdiverse, and yet monogenean communities infecting freshwater fish in the northern Holarctic are variable and often impoverished. This is a result of extinctions during periods of glaciation when the host fishes experienced range contraction. Fish species recolonised northern Europe by one of three routes; stenohaline fishes recolonised from the Black Sea basin via DanubeRhine or Dnieper−Dniester−Vistula connections. These fish retain complex rich monogenean faunas with numerous species of Dactylogyrus and Paradiplozoon. Anadromous fishes, recolonising via marine migrations along the coast, and cold−water fishes surviving in refugia close to the ice sheets, have impoverished monogenean faunas, characterised by gyrodactylid and ancyrocephalid species. However, there may be great complexity, due to the evolution of new hostparasite interactions within specific watersheds before, during and after the Last Glacial Maximum (LGM). This is demonstrated using examples from the sticklebacks (Gasterosteus aculeatus) and the bullheads (Cottus gobio). Finally, the evolution of Gyrodactylus salaris from a clade of G. thymalli is described, and the role of glaciation in stimulating the evolution of numerous clades of the latter is discussed. This latter example represents a unique opportunity to study speciation by host shift in real time.
