A global review of problematic and pathogenic parasites of farmed tilapia

Reviews in Aquaculture, Volume 15, Issue S1, Page 92-153, February 2023., 2023
Abstract Over the past 80 years, tilapia have been translocated globally for aquaculture; active production is recorded in >124 countries. Of 7 million tonnes of tilapia produced in aquaculture, 79% is from 79 countries outside the natural range of tilapia.

Natural occurrence of Diplostomum spp. in farm-raised African catfish (Clarias gariepinus) from Oyo state, Nigeria

International Journal of Veterinary Science and Medicine, 2016
Diplostomum species are the parasites responsible for diplostomiasis in fish which may cause blindness, eyefluke, severe ocular disease, opacity of the lens and many other affections. The parasites use many organisms including fish as a host.

Integrative taxonomic approach to the cryptic diversity of Diplostomum spp. in lymnaeid snails from Europe with a focus on the ‘Diplostomum mergi’ species complex

Parasites & Vectors, 2015
Background Recent molecular studies have discovered substantial unrecognised diversity within the genus Diplostomum in fish populations in Europe and North America including three species complexes.

Seasonality of salmonid parasites from flow‐through aquaculture in northern Germany: Emphasis on pathogenicity of Diplostomum spp. metacercaria

Aquaculture, Fish and Fisheries, 2022
The aim of the present study was to identify the parasite fauna of cultured rainbow trout (Oncorhynchus mykiss Walbaum, 1792) and Arctic charr (Salvelinus alpinus (L.)) from a flow‐through aquaculture system at Lake Tollense in northern Germany. The fish

The helminth fauna of brown trout (Salmo trutta) from a sub-alpine lake revisited after 40 years with introduced European minnow (Phoxinus phoxinus)

Fauna Norvegica, 2021
The helminth fauna of brown trout (Salmo trutta) in the Norwegian subalpine lake, Øvre Heimdalsvatn was studied by examination of gills, eyes, body cavity, kidney, stomach, pyloric region and intestine in a total of 112 brown trout randomly sampled in ...

Exploring the diversity of Diplostomum (Digenea: Diplostomidae) in fishes from the River Danube using mitochondrial DNA barcodes

Parasites & Vectors, 2017
Background Metacercariae of Diplostomum are important fish pathogens, but reliable data on their diversity in natural fish populations are virtually lacking. This study was conducted to explore the species diversity and host-parasite association patterns

Enigmatic decline of a common fish parasite (Diplostomum spp.) in the St. Lawrence River: Evidence for a dilution effect induced by the invasive round goby

International Journal for Parasitology: Parasites and Wildlife, 2017
As they integrate into recipient food webs, invasive exotic species may influence the population dynamics of native parasites. Here we assess the potential impact of the Eurasian round goby (Neogobius melanostomus) on the abundance of eyeflukes of the ...

Complete mitochondrial genomes and nuclear ribosomal RNA operons of two species of Diplostomum (Platyhelminthes: Trematoda): a molecular resource for taxonomy and molecular epidemiology of important fish pathogens

Parasites & Vectors, 2015
Background The genus Diplostomum (Platyhelminthes: Trematoda: Diplostomidae) is a diverse group of freshwater parasites with complex life-cycles and global distribution.

Preliminary survey on parasite fauna of pumpkinseed sunfish, Lepomis gibbosus (Linnaeus, 1758) (Pisces, Teleostei, Centrarchidae) from warm-water discharge canal of the "Pomorzany" power plant in Szczecin, Poland [PDF]

Acta Ichthyologica et Piscatoria, 1994
A total of 103 pumpkinseed sunfish L. gibbosus was surveyed for parasites. Fourteen parasite species representing six higher taxa were recovered. Of the fish examined, 72.8 % were found to harbour parasites. The most prevalent were glochidia of Unio sp. (
