A Long Temporal Study of Parasitism in Asexual‐Sexual Populations of Carassius gibelio: Does the Parasite Infection Support Coevolutionary Red Queen Dynamics?

open access: yesBioMed Research International, Volume 2018, Issue 1, 2018., 2018
Carassius gibelio is an extraordinary cyprinid species exhibiting both sexual and asexual reproduction. We hypothesized that parasitism selection is one of the potential mechanisms contributing to the coexistence of the two reproductive forms of C. gibelio living in the same habitat.

Host searching in Argulus foliaceus L. (Crustacea: Branchiura): the role of vision and selectivity

open access: yesParasitology, 1998
In laboratory experiments, the swimming behaviour of the ectoparasite Argulus foliaceus and its infection rates on juvenile perch (Perca fluviatilis) and roach (Rutilus rutilus) were examined. The highest infection rate and a preference for perch juveniles were obtained in darkness, the lowest infection rate and a lack of preference in the ...

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

open access: yesJournal of Fish Biology, Volume 105, Issue 6, Page 1501-1539, December 2024.
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 ...

Immune response in diseased and healthy common carp exposed to carp edema virus

open access: yesJournal of Fish Diseases, Volume 47, Issue 11, November 2024.
Abstract The common carp is one of the most economically valuable freshwater fish worldwide and its aquaculture can be severely affected by the koi sleepy disease (KSD)/carp edema virus disease (CEVD). This study explores a natural outbreak of CEVD in a pond containing both clinically healthy and diseased fish of various origins exposed to the virus ...

Parasite load, rather than parasite presence, decreases upstream movement in Trinidadian guppies Poecilia reticulata

open access: yesJournal of Fish Biology, Volume 105, Issue 1, Page 177-185, July 2024.
Abstract Several factors influence whether an organism remains in its local habitat. Parasites can, for example, influence host movement by impacting their behavior, physiology, and morphology. In rivers, fish that swim efficiently against the current are able to maintain their position without being displaced downstream, a behavior referred to as ...
