Parasite assemblages in fish hosts

open access: yesBio-Research, 2010
A review of various factors affecting parasite assemblages in fish hosts is presented. These factors are broadly divided into two: Biotic and abiotic factors. Biotic factors such as host age and size, host size and parasites size, host specificity, host diet and host sex and their influence on the abundance and distribution of parasites are considered ...

Changes in the level of oxidative stress markers in Indian catfish (Wallago attu) infected with Isoparorchis hypselobagri

open access: yesBeni-Suef University Journal of Basic and Applied Sciences, 2021
Background Helminth infection and infestation in fishes are detrimental and have a major effect on fish health and fish production. Among various factors, parasitic infections are known to modulate antioxidant defences in fish.

Fish Skin Microbiomes Are Highly Variable Among Individuals and Populations but Not Within Individuals

open access: yesFrontiers in Microbiology, 2022
Fish skin-associated microbial communities are highly variable among populations and species and can impact host fitness. Still, the sources of variation in microbiome composition, and particularly how they vary among and within host individuals, have ...

Comparative analysis of microbial communities associated with the gill, gut, and habitat of two filter-feeding fish

open access: yesAquaculture Reports, 2020
Host-associated microbiota play important roles in the nutrition, immune system, and health of fish. However, the composition, diversity, and function of microbiota associated with certain niches in fish bodies and fish habitats remain to be elucidated ...

Aggregation patterns of macroendoparasites in phylogenetically related fish hosts [PDF]

open access: yesParasitology, 2010
SUMMARYMacroparasites are generally aggregated within their hosts with infection and aggregation levels resulting from a continuous arms race between maintaining high mating probability and host mortality low for which host and environmentally related factors contribute to some extent.

The characteristics of the infection of juvenile Atlantic salmon with glochidia of the freshwater pearl mussel in rivers of Northwest Russia

open access: yesKnowledge and Management of Aquatic Ecosystems, 2016
The decline of freshwater pearl mussel (Margaritifera margaritifera L.) populations is globally well documented, but there is a lack of knowledge concerning the status of the species and its interaction with host fishes in the rivers ...

Sea lice infestation level alters salmon swimming depth in sea-cages

open access: yesAquaculture Environment Interactions, 2016
Host-parasite systems are often characterised by a co-evolutionary arms race, with avoidance behaviour being the first line of defence for hosts. In aquatic ecosystems, the rapid rise of fish farming has elevated host abundance, altering the context of ...

Host-Parasite Interactions in Some Fish Species [PDF]

open access: yesJournal of Parasitology Research, 2012
Host-parasite interactions are complex, compounded by factors that are capable of shifting the balance in either direction. The host's age, behaviour, immunological status, and environmental change can affect the association that is beneficial to the host whereas evasion of the host’s immune response favours the parasite.
