Lethrinitrema gibbus n. g., n. sp. and L. dossenus n. sp. are described from the fish Lethrinus rubrioperculatus Sato collected off New Caledonia, South Pacific. Members of Lethrinitrema n. g. (Ancyrocephalidae) are characterised by having two pyriform haptoral reservoirs and ventral anchors with lateral grooves. The elongate tubular distal end of each reservoir bifurcates, draining into a superficial lateral groove on each side of the ventral anchors. The haptoral reservoirs are postulated to store secretory products which assist in attachment to the host. Lethrinitrema spp. also possess tandem gonads, a male copulatory organ without an accessory piece or with thinly sclerotised accessory piece, and a dextrolateral, non-sclerotised vaginal bulb. The two new species have small, poorly demarcated haptors with small haptoral armament and a crown-like piece on the tip of the inner root of the ventral anchors. They differ from each other in the shape and size of the ventral bar and male copulatory organ (40-45 μm in length in L. gibbus vs 24-30 μm in L. dossenus). Three other species, previously included in Haliotrema Johnston & Tiegs, 1922, are transferred to Lethrinitrema, i.e. L. chrysostomi (Young, 1968) n. comb., L. fleti (Young, 1968) n. comb. (both briefly redescribed from paratypes) and L. lethrini (Yamaguti, 1937) n. comb. All species of Lethrinitrema parasitise Lethrinus spp. (Lethrinidae), and there is evidence for the existence of further Lethrinitrema spp. on Lethrinus spp. in the Indo-Pacific region.

“…In the present study, C. sclerosus showed less preference to the gills of cultured O. niloticus than that of the red hybrid tilapia. This is because the natural host for C. sclerosus is O. mossambicus (see Le Roux and Avenant-Oldewage 2010 ) and the red hybrid tilapia might possess substances that derived from its parental host. Other biotic and abiotic factors included water quality (Madanire-Moyo et al 2012 ), host sex and size (Akoll et al 2011 ; Ibrahim 2012 ; Madanire-Moyo et al 2011 ; Tombi et al 2014 ; Vanhove et al 2015 ) may also influence the species richness and infection level of monogeneans on tilapia fish.…”

Gill monogeneans of Nile tilapia (Oreochromis niloticus) and red hybrid tilapia (Oreochromis spp.) from the wild and fish farms in Perak, Malaysia: infection dynamics and spatial distribution

Tilapia is one of the commercially important fish in Malaysia as well as in other parts of the world. An understanding of monogenean infection dynamics in tilapia fish may assist us in searching for some intervention measures in reducing the loss of fish caused by parasitic diseases. The present study aimed (1) to compare infection level of monogeneans between the wild and cultured Oreochromis niloticus, and between the cultured O. niloticus and cultured red hybrid tilapia, and (2) to examine the spatial distribution of monogenean species over the gills of the different host species. From a total of 75 fish specimens, six species of monogeneans from two genera: Cichlidogyrus (C. halli, C. mbirizei, C. sclerosus, C. thurstonae, C. tilapiae) and Scutogyrus (S. longicornis) were identified. Data showed that the infection level of cultured O. niloticus was higher than that of the wild O. niloticus, however, the former was lower than that of the cultured red hybrid tilapia. Higher species richness of monogeneans was observed in the cultured red hybrid tilapia as compared to the others. Results for spatial distribution showed that the monogeneans have no preference on the left or right sides of the gills. However, C. halli, C. mbirizei, and C. tilapiae showed preferences on specific gill arches in the cultured O. niloticus and red hybrid tilapia. In general, the gill arch IV harboured the least number of monogeneans. The susceptibility of monogenean infection between the different types of tilapia is discussed.

“…The eyes, intestines, visceral organs and pericardial cavity were all examined for parasites. Most of the parasites were identified using identification keys and key literature at the University of Vienna and at the Museum of Natural History, Vienna (Paperna 1980(Paperna , 1996Pariselle and Euzet 1995, 1998Scholz et al 2004;Le Roux and Avenant-Oldewage 2010;Abowei and Ezekiel 2011;Kuchta et al 2012). The terms used to describe the metacestodes are according to Chervy (2002).…”

Fish is an important food source for an estimated 300,000 people inhabiting the shores of Lake Turkana, Kenya. Despite its large size (7560 km2) and importance, the lake remains one of the least studied in the Great Lakes Region of Africa. This study describes the parasite community of the elongate tigerfish Hydrocynus forskahlii (Cuvier, 1819) and the redbelly tilapia Tilapia zillii (Gervais, 1848). A total of 87 individuals (43 H. forskahlii and 44 T. zillii) were dissected and examined for parasites. Two taxa infected H. forskahlii, the dominant one being an anisakid nematode Contracaecum sp. (L3) (P = 83.7%, mean intensity (MI) = 46.0, abundance (A) = 38.5). Twelve parasite taxa were recovered from T. zillii, with metacestodes of the gryporhynchid cestode Amirthalingamia macracantha being dominant (P = 79.5, MI = 10.3, A = 8.2). This was the first report of a mixture of merocercoids and plerocercoids in the same host. Fish size was positively correlated with the major parasite infection levels, but, the prevalence of Contracaecum sp. in H. forskahlii was negatively correlated with size, probably reflecting ontogenetic shifts in habitats and diets with age. Fish sex was not a significant influencing factor, with the exception of Contracaecum sp. in H. forskahlii, where prevalence differed significantly between sexes (p<0.05), with the females having a higher prevalence than the males. We conclude that H. forskahlii had a poor parasitic community but that the infection levels with Contracaecum sp. were high. T. zillii had a rich parasite fauna, although, most parasites occurred at low intensities.
