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

Journal 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

Journal 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 ...

Gyrodactylus in the spotlight: how exposure to light impacts disease and the feeding behavior of the freshwater tropical guppy (Poecilia reticulata)

Journal of Fish Biology, Volume 105, Issue 3, Page 682-690, September 2024.
Abstract Artificial light at night (ALAN) negatively impacts organisms in many ways, from their feeding behaviors to their response and ability to deal with disease. Our knowledge of ALAN is focused on hosts, but we must also consider their parasites, which constitute half of all described animal species.

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

Journal 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 ...

Lufenuron treatment temporarily represses gene expression and affects the SUMO pathway in liver of Atlantic salmon

Journal of Fish Diseases, Volume 47, Issue 2, February 2024.
Abstract Lufenuron is a benzoylurea insecticide currently in use to combat sea lice infestation in salmon aquaculture in Chile. With pending approval in Norway, the aim of this work was to study the uptake and toxicity of lufenuron in liver tissue of Atlantic salmon.

Pathology caused by introduced Neoergasilus japonicus (Copepoda: Ergasilidae) to the skin of indigenous Tilapia sparrmanii in South Africa and scanning electron microscopy study of wound‐inflicting structures

Journal of Fish Diseases, Volume 47, Issue 1, January 2024.
Abstract Neoergasilus japonicus, a fish ectoparasite indigenous to eastern and southern Asia, has been introduced to various regions, including Europe and North and South America, where it spreads at an alarming rate. The parasite is not host‐specific. It was also collected from the Vaal‐Orange and Limpopo river systems in South Africa.

Host-Parasite-Environment Interactions on the Infestation of Argulus africanus Thiele, 1900 on Nile tilapia in Lake Hawassa, Ethiopia

Ethiopian Journal of Science and Sustainable Development
Argulus is one of the economically important ectoparasite of Nile tilapia (Oreochromis niloticus L. 1758); however, it poses a serious problem both in culture and capture fisheries globally. This investigation was done, from May 2022 to January 2023, to

Low levels of crustacean parasite infestation in fish species from the Matapi River in the state of Amapá, Brazil

Revista Brasileira de Parasitologia Veterinária
This first study investigated the crustacean parasite fauna in 66 species of fish from the Matapi River basin, state of Amapá (Brazil). Fish were collected every two months between March 2012 and August 2013, encompassing dry and rainy seasons. Among the
