While investigating the trematode parasite infestation in the freshwater fishes of South Western Ghats, India we came across echinostome infection in three species of fishes Pseudosphromenus cupanus, Lepidocephalichthys thermlis and Aplochelus lineatus. Detailed histopathological studies on the infected kidney of the freshwater fish L. thermlis revealed severe damage and degeneration of their cells. The prevalence, intensity and mean abundance of infection of Echinostoma sp. in the three fishes were also recorded. The prevalences of Echinostoma sp. infection in the freshwater fishes P. cupanus, A. lineatus and L. thermalis were 5.55%, 66.66% and 25%, the intensities of infection were 4.5, 36 and 1, and the mean abundances were 0.25, 24 and 0.25, respectively.

“…Known parasitic helminths of fish are different species of nematodes (roundworms), flukes and cestodes (tapeworms) (e.g. see Bristow (1993), Jyrwa et al (2016), Eiras (2016), Rauque et al (2018)). These are larger internal parasites, of which several can be observed with the naked eye in infected fish (Jansson & Vennerstr€ om, 2014).…”

Combating and controlling sea lice causes large economic costs for the farmers, with estimated values of more than 305 million euros (€) per year. Increased resistance against traditional chemotherapeutants due to evolutionary drivers in the sea lice combined with the lack of an effective vaccine and few other chemical treatments available are expected to cause these costs to increase. Several possible methods for managing sea lice infestations have been investigated, but only cleaner fish has proven to have an effect on lice levels. Cleaning activity is well known in marine fish and has been observed in the wild as a form of symbiosis between two species: one species, the 'client' fish, seek out the other species, the 'cleaner' fish, to have ectoparasites and dead tissue cleared from its body. The Atlantic lumpfish is a relatively new aquaculture species, and wild-caught mature fish are used as brood stock for farmed production. This poses a biosecurity risk, as wild fish can carry pathogens, and the use of quarantine and health screening is recommended. Vaccine development is unfortunately lagging far behind relatively to the wide spread and high utilisation of the fish. This review contains description of the main pathogens and diseases that affect cleaner fish.

“…Fish were euthanised by severing the spinal cord with a single cut posterior to the skull, dissected and the intestine examined for digenean trematodes. Freshly recovered parasites were washed in saline solution and preserved either with 70% ethanol for light and scanning electron microscopy (SEM) study (Dos Santos et al, 2015;Jyrwa et al, 2016), 10% neutral buffered formalin for histological study, or 96% ethanol for genetic analyses (Blasco-Costa et al, 2016). Additionally, some of the parasites were slightly flattened in a drop of alcoholformalin-acetic acid (AFA) between a glass slide and coverslip, and subsequently transferred to 70% ethanol (Jyrwa et al, 2016).…”

Masenia nkomatiensis n. sp. (Digenea: Cephalogonimidae) from Clarias gariepinus (Burchell) (Clariidae) in Incomati Basin, Mozambique

A new species of Masenia Chatterji, 1933 is described based on material from the intestine of Clarias gariepinus (Burchell) in the Incomati River, Mozambique. The combination of morphological characteristics and analysis of 18S and 28S rDNA sequences delineated the specimens found in the present study as a distinct species. The new form is distinguished from other Masenia spp. in having a large reniform seminal receptacle, a cirrus-sac ending anterior to the ventral sucker, intestinal caeca extending into the hindbody to the level of the posterior testis, and the vitelline fields extending anteriorly to the ventral sucker and posteriorly to the middle of the ovary. Notably, the new form is the only record of African species having a sac-shaped excretory vesicle. Analysis of 28S rDNA sequence data supported its placement in the Cephalogonimidae Looss, 1899. 18S analyses also supported its placement in this family but showed it was not closely related to Masenia bangweulensis (Beverley-Burton, 1962), the sole other African species for which genetic data is currently accessible. The total pairwise differences for 18S and 28S sequences showed the new form differing from other cephalogonimids. Thus, both morphological and genetic characteristics indicate that the present form represents a distinct species, here described as Masenia nkomatiensis n. sp. An updated key to African Masenia spp., now five, is provided. This article was registered in the Official Register of Zoological Nomenclature (ZooBank) as CD42E301-768B-498B-8B67-80FDA85BB40A.
