Relationship between Water Quality Parameters and Parasite Infestation in Farmed Oreochromis niloticus in Selected Rift Valley Counties, Kenya

open access: yesAquaculture Research, Volume 2024, Issue 1, 2024.
Globally, parasitic infections hinder aquaculture productivity and sustainability. Improper water quality parameters reduce fish immunity, make them susceptible to parasites, and enhance parasitic proliferation in culture systems. Subsequently, this study aimed to determine the prevalence and intensity of ecto‐ and endo‐parasite infesting Oreochromis ...

Parasite-induced aggression and impaired contest ability in a fish host

open access: yesParasites & Vectors, 2010
Background Success of trophically transmitted parasites depends to a great extent on their ability to manipulate their intermediate hosts in a way that makes them easier prey for target hosts. Parasite-induced behavioural changes are the most spectacular

Prevalence of Diplostomum spathaceum infectious in some endemic fishes of water resources in West Azerbaijan province

open access: yes‬‭Majallah-i ̒Ilmī-i Shīlāt-i Īrān, 2013
Diplostomum spathaceum is a digenean parasite with an indirect life cycle. Its mature stage lives in gull's intestine, cercariae in snails (Lymnaeidae) liver and metacercariae stage in piscine, amphibian, and mammalian eyes.

Ecological divergence of closely related Diplostomum (Trematoda) parasites

open access: yesParasitology, 2006
Parasite life-cycles present intriguing model systems to study divergence in resource use and ecology between parasite taxa. In ecologically similar taxa, consistent selective forces may lead to convergence of life-history traits, but resource overlap and similarity of life-cycles may also promote divergence between the taxa in (1) use of host species ...

Personality differences in two minnow populations that differ in their parasitism and predation risk

open access: yesFrontiers in Ecology and Evolution, 2015
Animals are often individually consistent in their behavior, not only over time, but also across different functional contexts. Recent research has focused on phenotypic and evolutionary mechanisms explaining such personality differences through ...
