Temporal stability of polymorphic Arctic charr parasite communities reflects sustained divergent trophic niches. [PDF]

Ecol Evol, 2022
Our study showed that anthropogenic modification of the fish community can result in changes to the parasite fauna in the system, with the establishment of new species and varying levels of infection of native parasites over time. However, our model hosts were able to maintain their trimorphic population despite changes in the fish community.

Diplostomum-Induced Sac Formation in Lenses of Ameiurus Bullheads: A Host Defence Response? [PDF]

J Fish Dis
ABSTRACT Trematodes of the genus Diplostomum (Diplostomidae) are widely distributed and significant fish pathogens known for causing a range of negative effects. Any mechanism that protects the host from the parasite thus represents an evolutionary advantage.

Unclear host taxonomy hinders parasite studies: An up-to-date checklist of the protozoan and metazoan parasites of Phoxinus minnows (Teleostei: Leuciscidae). [PDF]

J Fish Biol
Abstract Phoxinus minnows are small freshwater fish found throughout Eurasia. The taxonomy of this genus is still under investigation, and new species are regularly described. They are frequently introduced outside their native range due to their use as live bait for angling, and such fish introductions can have diverse impacts on the recipient areas ...

Fish morphological and parasitological traits as ecological indicators of habitat quality in a Mediterranean coastal lagoon

Aquatic Conservation: Marine and Freshwater Ecosystems, Volume 33, Issue 11, Page 1229-1244, November 2023., 2023
Abstract Coastal lagoons are key ‘transitional’ aquatic environments for biodiversity conservation. Ecological indicators are useful tools for the management of water resources in the European Union. Among different biological communities, fish are a very sensitive tool to assess environmental integrity.

Unlocking the genome of perch – From genes to ecology and back again

Ecology of Freshwater Fish, Volume 32, Issue 4, Page 677-702, October 2023., 2023
Abstract Eurasian perch Perca fluviatilis has been a popular model species for decades in the fields of aquatic ecology, community dynamics, behaviour, physiology and ecotoxicology. Yet, despite extensive research, the progress of integrating genomic perspective into existing ecological knowledge in perch has been relatively modest.

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.

Improving tilapia biosecurity through a value chain approach

Reviews in Aquaculture, Volume 15, Issue S1, Page 57-91, February 2023., 2023
Abstract Tilapia aquaculture is a major source of animal protein, with global production reaching over 6 million tonnes in 2020. The rapid growth of the tilapia sector has led to a number of emerging disease threats and subsequent production losses. Risk analysis can provide a targeted approach for improving biosecurity in the tilapia sector.

Praziquantel (Droncit) is effective against diplostomosis of grasscarp Ctenopharyngodon idella and silver carp Hypophthalmichthys molitrix [PDF]

, 1991
In laboratory experiments praziquantel (Droncit) effectively destroyed metacercariae of Diplostomum spathaceum (s. l.) parasitizing the eye lens of grasscarp Ctenopharyngodon idella and silver carp Hypophthalmichthys molitrix.

Morphological and molecular differentiation of Diplostomum spp. metacercariae from brain of minnows (Phoxinus phoxinus L.) in four populations of northern Europe and East Asia

Infection, Genetics and Evolution, 2021
Metacercariae of trematodes from the genus Diplostomum are major helminth pathogens of freshwater fish, infecting the eye or the brain. The taxonomy of the genus Diplostomum is complicated, and has recently been based mainly on the molecular markers. In this study, we report the results of the morphological and molecular genetic analysis of diplostomid

Differences in parasite community composition support ecological differentiation in a freshwater gadoid fish

Ecology of Freshwater Fish, Volume 31, Issue 4, Page 693-700, October 2022., 2022
Abstract Several northern freshwater fishes have gone through rapid adaptive radiation after the last glacial period, resulting in new species or intraspecific morphs with distinct life histories. Parasite infections can promote adaptive radiations and spatiotemporal differences in patterns of infections can potentially reveal incipient or ongoing ...
