Box 56, Dunedin 9054, New Zealand; [email protected] * Correspondence: [email protected]; Tel.: +47-481-37-867 Abstract: Free-living species often receive greater conservation attention than the parasites they support, with parasite conservation often being hindered by a lack of parasite biodiversity knowl- edge. This study aimed to determine the current state of knowledge regarding parasites of the Southern Hemisphere freshwater fish family Galaxiidae, in order to identify knowledge gaps to focus future research attention. Specifically, we assessed how galaxiid–parasite knowledge differs among geographic regions in relation to research effort (i.e., number of studies or fish individuals examined, extent of tissue examination, taxonomic resolution), in addition to ecological traits known to influ- ence parasite richness. To date, ~50% of galaxiid species have been examined for parasites, though the majority of studies have focused on single parasite taxa rather than assessing the full diversity of macro- and microparasites. The highest number of parasites were observed from Argentinean galaxiids, and studies in all geographic regions were biased towards the highly abundant and most widely distributed galaxiid species, Galaxias maculatus. -

E-mail: mustafakoyun16@ yahoo.com. Tel: +90 (0) 426 2132550. Accepted 7 January, 2011 In this research, gill parasites of two Cyprinid fish ( Alburnus alburnus and Carassius carassius ) from the upper basin of Porsuk river were studied. Fish samples were obtained monthly at intervals during 2003 to 2004. The intensity of infection was investigated depending on the parasite species, the years and seasons, and host fish species. Four Dactylogyrus species were identified in the gills of host fishes Dactylogyrus fraternus (Wegener, 1909), Dactylogyrus alatus (Linstow, 1878) and Dactylogyrus minutus (Kulwiec, 1927) on A. alburnus and D. minutus and Dactylogyrus anchoratus (Dujardin, 1845) on C. carassius. The prevalence, abundance and mean intensity of Dactylogyrus infection for each parasite species was determined as follow: D. fraternus (49.6%, 2.58 and 5.20), D. alatus (28.1%, 0.61 and 2.18) and D. minutus (35.1%, 1.61 and 4.61) in A. alburnus and D. minutus (40.5%, 1.00 and 2.49), D. anchoratus (37.6%, 0.38 and 4.63) in C. carassius. The highest intensity was recorded for D. fraternus while the lowest was recorded in D. -

Parasites of Coral Reef Fish: How Much Do We Know? with a Bibliography of Fish Parasites in New Caledonia
Belg. J. Zool., 140 (Suppl.): 155-190 July 2010 Parasites of coral reef fish: how much do we know? With a bibliography of fish parasites in New Caledonia Jean-Lou Justine (1) UMR 7138 Systématique, Adaptation, Évolution, Muséum National d’Histoire Naturelle, 57, rue Cuvier, F-75321 Paris Cedex 05, France (2) Aquarium des lagons, B.P. 8185, 98807 Nouméa, Nouvelle-Calédonie Corresponding author: Jean-Lou Justine; e-mail: [email protected] ABSTRACT. A compilation of 107 references dealing with fish parasites in New Caledonia permitted the production of a parasite-host list and a host-parasite list. The lists include Turbellaria, Monopisthocotylea, Polyopisthocotylea, Digenea, Cestoda, Nematoda, Copepoda, Isopoda, Acanthocephala and Hirudinea, with 580 host-parasite combinations, corresponding with more than 370 species of parasites. Protozoa are not included. Platyhelminthes are the major group, with 239 species, including 98 monopisthocotylean monogeneans and 105 digeneans. Copepods include 61 records, and nematodes include 41 records. The list of fish recorded with parasites includes 195 species, in which most (ca. 170 species) are coral reef associated, the rest being a few deep-sea, pelagic or freshwater fishes. The serranids, lethrinids and lutjanids are the most commonly represented fish families. Although a list of published records does not provide a reliable estimate of biodiversity because of the important bias in publications being mainly in the domain of interest of the authors, it provides a basis to compare parasite biodiversity with other localities, and especially with other coral reefs. The present list is probably the most complete published account of parasite biodiversity of coral reef fishes. -

Somatic Musculature in Trematode Hermaphroditic Generation Darya Y
Krupenko and Dobrovolskij BMC Evolutionary Biology (2015) 15:189 DOI 10.1186/s12862-015-0468-0 RESEARCH ARTICLE Open Access Somatic musculature in trematode hermaphroditic generation Darya Y. Krupenko1* and Andrej A. Dobrovolskij1,2 Abstract Background: The somatic musculature in trematode hermaphroditic generation (cercariae, metacercariae and adult) is presumed to comprise uniform layers of circular, longitudinal and diagonal muscle fibers of the body wall, and internal dorsoventral muscle fibers. Meanwhile, specific data are few, and there has been no analysis taking the trunk axial differentiation and regionalization into account. Yet presence of the ventral sucker (= acetabulum) morphologically divides the digenean trunk into two regions: preacetabular and postacetabular. The functional differentiation of these two regions is already evident in the nervous system organization, and the goal of our research was to investigate the somatic musculature from the same point of view. Results: Somatic musculature of ten trematode species was studied with use of fluorescent-labelled phalloidin and confocal microscopy. The body wall of examined species included three main muscle layers (of circular, longitudinal and diagonal fibers), and most of the species had them distinctly better developed in the preacetabuler region. In majority of the species several (up to seven) additional groups of muscle fibers were found within the body wall. Among them the anterioradial, posterioradial, anteriolateral muscle fibers, and U-shaped muscle sets were most abundant. These groups were located on the ventral surface, and associated with the ventral sucker. The additional internal musculature was quite diverse as well, and included up to twelve separate groups of muscle fibers or bundles in one species. -

Study of Parasitic Effect of Dactylogyrus Sp. on Indian Major Carps
© 2020 JETIR October 2020, Volume 7, Issue 10 www.jetir.org (ISSN-2349-5162) Study of parasitic effect of Dactylogyrus sp. on Indian Major Carps Dr. Pratibha Pathak P.G. Department of Zoology, LNMU, Darbhanga, Bihar, India. Abstract The current study examines the parasitic effects of Dactylogyrus sp. on Indian major carps. Only symptomatic and moribund samples of diseased fishes comprised of fry/fingerlings and adults of IMC were collected and were brought to the laboratory for patho-morphological and patho-anatomical examinations. Photomicrographs of the most characteristic regions of histopathological lesions in the stained tissues of diseased fish samples were taken. In severe infestations the fishes showed growth retardation. Partial suffocation, lethargic swimming behaviour and their gills were very pale in colour and had haemorrhagic and inflamed areas at the sites of parasite attachments. The main histopathological lesions and changes were seen in the gills where the parasites were found attached to the lamellar tissues causing local erosions of the epithelium. Hyperplasia of the secondary lamellar epithelium and fusion of adjacent secondary lamellae were the significant tissue level reactions caused by the parasites. No changes were noticed in other organs of the affected fishes. We suggest that histopathological analysis for parasites in fish is useful tool for fish health monitoring. Key words: Dactylogyrus, histopathology, parasitic, secondary lamellar epithelium. INTRODUCTION: The three Indian major carps, namely Catla (Catla catla), Rohu (Labeo rohita) and Mrigal (Cirrhinus mrigala) contribute 87% of total fresh water aquaculture production (Annual Report , 2016-2017). Dactylogyrosis is a disease caused by the monogenetic trematode, Dactylogyrus sp. was found to cause severe damage in the gills of the highly affected fishes. -

New Species of Diplectanum (Monogenoidea: Diplectanidae
FOLIA PARASITOLOGICA 55: 171-179, 2008 New species of Diplectanum (Monogenoidea: Diplectanidae), and proposal of a new genus of the Dactylogyridae from the gills of gerreid fishes (Teleostei) from Mexico and Panama Edgar F.

While investigating the parasites of several marine fishes from the Western Atlantic, the Southern Gulf of Mexico and Central America (Panama), the following monogenoidean species from the gills of gerreid fishes (Gerreidae) were found: Diplec- tanum gatunense sp. n. (Diplectanidae) and Octouncuhaptor eugerrei gen. et sp. n. (Dactylogyridae) in Eugerres brasilianus (Cuvier) from Gatun Lake in the Panama Canal Watershed, and Diplectanum mexicanum sp. n. in Diapterus rhombeus (Cuvier) from the coast of Campeche State, Mexico. New diplectanid species are distinguished from other species of the genus by the general morphology of the copulatory complex and by the shape of the anchors and bars on the haptor. Octouncuhaptor gen. n. is proposed for its new species having slightly overlapping gonads (testis posterodorsal to the ovary), a dextrolateral vaginal aper- ture, a copulatory complex consisting of a coiled male copulatory organ with counterclockwise rings with the base articulated to the accessory piece, 8 pairs of hooks and the absence of anchors and bars on haptor.
