Freshwater fishes are the most common hosts of the glochidia (parasitic larvae) of freshwater mussels (Bivalvia: Unionoida: Unionoidea). Velesunio angasi (Sowerby, 1867) (Hyriidae), is the only known hyriid species recorded from the Fortescue River in the Pilbara region of Western Australia. Eleven species of fish (n = 516) were captured from pools of the Fortescue River in June 2010. Small, white, bladder-like cysts were observed on Neosilurus hyrtlii Steindachner, 1867, though not on any of the remaining 10 species examined. Light microscopy of sectioned cysts revealed that they contained glochidia that were of similar size and shape to those of V. angasi. Glochidia were found on 73.2% of 168 N. hyrtlii examined, with a mean intensity of 3.3 cysts per infested fish. Prevalence was significantly greater on smaller fish (P < 0.01); however, no relationship between size and intensity of infestation was observed. This represents the first record of glochidia infestation on fish from the Pilbara region.

Upstream migration of juvenile stages of temperate Australian amphidromous fish typically coincides with seasonally low river discharge when hydraulic (e.g. cascades) and physical (e.g. rock bars) barriers may be common. The ability to ‘climb’ or ‘jump’ may be expected to assist in negotiating low-flow barriers; however, it is presumed to be limited to a few native Australian freshwater fishes. Juvenile stages of Galaxias truttaceus Valenciennes, 1846 were observed ‘climbing’ and ‘jumping’ to successfully negotiate a low, vertical weir wall during their upstream recruitment migrations in south-western Australia. Based on this observation, we propose initial definitions for ‘climbing’ and ‘jumping’ to describe locomotory strategies employed by fishes to negotiate obstacles that would otherwise prevent free passage by normal swimming behaviour. Greater knowledge of the climbing, jumping and swimming performance, especially for small-bodied species and early life stages, will help improve the management of instream barriers for this critically endangered species and other freshwater fishes of southern Australia.

AbstractOreochromis mossambicus (Peters 1852) and Oreochromis niloticus niloticus Linnaeus, 1758 are two popular freshwater fishes introduced from Africa to India. There are many records of different species of trichodinid ectoparasites infesting wild and cultured cichlids in Africa, but no such study has been conducted on this parasitic group in India. The fishes Oreochromis mossambicus and Oreochromis niloticus niloticus were investigated for the occurrence of trichodinid ciliophorans. Oreochromis mossambicus was found positive for two species, viz., Trichodina centrostrigeata Basson, Van As & Paperna, 1983 and Paratrichodina africana Kazubski & El-Tantawy, 1986. Oreochromis niloticus niloticus was found not to be infested with any species of trichodinid ciliophorans, although, interestingly, Paratrichodina africana was first discovered in this host fish. Comparative descriptions and prevalence of these two above-mentioned species are presented.

This study was carried out at the Yenice Irrigation Pond between October 1999 and October 2000. For this study 368 roach (Rutilus rutilus) were examined and 37 parasites and 93 Ligula intestinalis were found in the abdominal cavity of the host (prevalence 10.1%, mean intensity 2.51 specimens/fish). Based on season, the highest number of infected fish occurred during summer (33.3%, 4 parasite/fish), and during the other season the mean intensity of infection was relatively low (prevalence 3.3%, 1 specimens/fish). On the other hand, the parasite species was determined especially on small and medium host fish sizes (2.17-100%). Basic criteria for the assessment of the parasite species of host fish were the general parameters related to parasite populations, which are prevalence, mean intensity, seasonal variation, and relationship between host size and infection.

Abstract The study was conducted during September 2018-August 2019 to study the digenetic trematode infection in fresh water fishes of some of the water bodies viz. Gho-manhasan, Chakrali and Chadwal of Jammu region of J&K union territory A total of 220 fishes comprising Ophiocephalus punctatus and Xenentodon cancila belonging to families Channidae and Belonidae respectively were examined. A total of 4 digenetic trematode parasites belonging to 4 different families i.e., Euclinostomum heterostomum (Clinostomidae Luhe, 1901); Phyllodistomum tripathi (Gorgoderidae Looss, 1901); Genarchopsis piscicola (Hemiuridae, Luhe, 1901), and Bucephalopsis karvei (Bucephalidae Poche, 1907) were detected. The overall prevalence of digenetic trematode infection was 65.90% and the mean intensity was 3.58. Among these Genarchopsis piscicola showed the highest prevalence (40.38%) with mean intensity 2.95 in the host fish Xenentodon cancila, while in other species the prevalence ranged between 26.23% and 34.62%. Present study authenticates the presence of several species of digenetic trematode parasites in the fishes inhabiting freshwater of J&K union territory.

Antipatharians are still poorly documented in the southeastern Pacific, with just eleven species reported in Chilean waters, all of them distributed in subtidal areas from 70 to 2000 m depth (Häussermann & Försterra, 2007; Cañete & Häussermann, 2012; Araya et al. 2016a). Among the family Schizopathidae Brook, 1889, which is characterized by polyps elongated in the direction of the axis and having a transverse diameter of 2 mm or more (Opresko, 2002), the recently described deep-water genus Alternatipathes Molodtsova & Opresko, 2017, encompasses two recognized species, Alternatipathes alternata (Brook, 1889), reported from abyssal basins (2670 to 5089 m depth) of the Indian and Pacific Oceans, and Alternatipathes bipinnata (Opresko, 2005), known from a few specimens collected in deep waters (1130 to 2846 m) off the Pacific coasts of northern Mexico and southern USA (Opresko, 2005; Molodtsova & Opresko, 2017).

Sharptooth catfish, Clarias gariepinus, from the Rietvlei Dam near Pretoria, South Africa were examined for internal platyhelminth parasites. Two adult cestodes, Polyonchobothrium clarias (stomach) (prev alence 71 %, mean intensity = 5, n = 7) and Proteocephalus glanduliger (anterior intestine) (prevalence 14 %, mean intensity = 2, n = 7), were found in the gut while metacercariae of one larval digenean, Ornithodiplostomum sp. (prevalence 14 %, mean intensity = 140, n = 7), were found encysted in the muscles. The morphology of these species, based on light and scanning electron microscopy as well as histological analysis, and how they differ from previously described specimens, are discussed. Ornithodiplostomum is a new record in southern Africa. Infection levels of the host fish were mild compared to records from previous surveys.

Raillietiella gigliolii is a Neotropical pentastomid parasite found in Amphisbaena alba. Collections were made in northeastern Brazil in a remnant area of Atlantic Forest (07º 10' S and 35º 05' W) in the municipality of Cruz do Espírito Santo, Paraíba State, and in a Humid Forest area (07º 16' S and 39º 26' W) on the slopes of the Chapada do Araripe Mountains, municipality of Crato, Ceará state, Brazil. Nine specimens of A. alba and 12 of A. vermicularis were collected to gather basic ecological data (prevalence and mean intensity of infection) concerning these parasites. Raillietiella gigliolii was found infecting the lungs of both species. The prevalence for A. alba was 55.5% (5/9), with a mean intensity of infection of 5.0 ± 2.53 and amplitudes of 1-13. A. vermicularis demonstrated prevalence of 50%, with a mean intensity of infection of 5.3 ± 2.1 and amplitudes of 1-14. This represents the first record of R. gigliolii as a parasite of A. vermicularis. Our results suggest that R. gigliolii is a generalist parasite species and that an overlapping diet is the determinant factor in the sharing of its final hosts.

In order to investigate the Chinese representatives from two genera of the tribe Oodini LaFerté-Sénectère, 1851, twenty-three Palaearctic and Oriental species of the genera Lachnocrepis LeConte, 1853 and Oodes Bonelli, 1810 are taxonomically reviewed. Because the species in question share a high degree of morphological similarity they are grouped in the “Oodes generic group”. The character-analysis showed that seven species belong to Oodes, including five species to Oodes s.str. and two species to Lachnocrepis (downgraded to subgenus). The remaining sixteen species are classified in three genera: ten species in Pseudoodes gen. n. (type species: Oodes cribristernis Bates, 1892), two species in Sundaoodes gen. n. (type species: Sundaoodes hainanensis sp. n.), and four species in Nothoodes gen. n. (type species: Oodes angustatus Lorenz, 2005). The taxa of Oodes s.str. and Pseudoodes gen. n. are arranged in two and four species groups, respectively.                Eleven species from three genera, including six new to science, are found in China: Oodes (Oodes) echigonus Habu & Baba, 1960, Oodes (Lachnocrepis) desertus Motschulsky, 1858, Oodes (Lachnocrepis) japonicus (Bates, 1873), Pseudoodes cribristernis (Bates, 1892) (first record for China), Pseudoodes rambouseki (Jedlička, 1931), Pseudoodes ampliusculus, sp. n. (type locality: Mingfenggu Valley, Jiangfengling Mountains, Hainan), Pseudoodes emeishanicus, sp. n. (type locality: Xixinsuo Temple, Emei Shan, Leshan City, Sichuan), Pseudoodes hunanensis, sp. n. (type locality: Xiaozhuangping, Tianping Shan, Sangzhi County, Hunan), Pseudoodes leigongshanicus, sp. n. (type locality: Xijiang Town, Leigong Shan, Leishan County, Guizhou), Pseudoodes tianlinensis, sp. n. (type locality: Cenwanglao Shan, Tianlin County, Guangxi), and Sundaoodes hainanensis, sp. n. (type locality: Nada Town, Danzhou City, Hainan). Two further new species, Sundaoodes kalimantanensis, sp. n. (type locality: Bukit Liang Mount, West Kalimantan Province, Indonesia) and Nothoodes bharat, sp. n. (type locality: Dwarakapuram Village, Naidupet Mandal, Nellore District, Andhra Pradesh, India), are also described.                The following new synonymies are proposed: Oodes parallelus Motschulsky, 1858, syn. n. of Oodes helopioides (Fabricius, 1792); Oodes parallelogrammus Motschulsky, 1858, syn. n. of Oodes helopioides (Fabricius, 1792); Oodes prolixus Bates, 1873, syn. n. of Oodes desertus Motschulsky, 1858; Simous viridissimus Louwerens, 1951, syn. n. of Pseudoodes coelestinus (Chaudoir, 1882). The synonymy of Oodes hahni Reitter, 1908 with Oodes desertus Motschulsky, 1858 is confirmed. Also, the following new combinations are introduced: Oodes japonicus (Bates, 1873), comb. n. of Lachnocrepis japonica Bates, 1873; Pseudoodes vicarius (Bates, 1873), comb. n. of Oödes vicarius Bates, 1873; Pseudoodes coelestinus (Chaudoir, 1882), comb. n. of Oodes coelestinus Chaudoir, 1882; Pseudoodes subcoriaceus (Chaudoir, 1882), comb. n. of Oodes subcoriaceus Chaudoir, 1882; Pseudoodes cribristernis (Bates, 1892), comb. n. of Oodes cribristernis Bates, 1892; Pseudoodes rambouseki (Jedlička, 1931), comb. n. of Holosoma rambouseki Jedlička, 1931; Nothoodes taprobanae (Andrewes, 1923), comb. n. of Oodes taprobanae Andrewes, 1923; Nothoodes longus (Andrewes, 1940), comb. n. of Oodes longus Andrewes, 1940; Nothoodes angustatus (Lorenz, 1998), comb. n. of Oodes angustatus Lorenz, 1998. Lectotypes are designated for Oodes parallelus Motschulsky, 1858, Oodes parallelogrammus Motschulsky, 1858, Oodes desertus Motschulsky, 1858, Oodes cribristernis Bates, 1892, Oodes hahni Reitter, 1908, Oodes thessalonicensis Schatzmayr, 1909, Oodes helopioides var. fiorii Porta, 1923, and Holosoma rambouseki Jedlička, 1931.                A key to the species, diagnoses, descriptions, notes on type specimens, relationships, distribution, bionomics when available, and figures of body, genitalia and other characters useful for taxonomy are provided. Numerous new records, including first country records for Romania, Israel, Nepal, China, Thailand, Laos, Vietnam, Brunei, and Indonesia, are registered.
