Salinity‐Induced Gene Expressions in Pangasius nasutus (Bleeker, 1863)

Aquaculture Research, Volume 2025, Issue 1, 2025.
This study was designed to evaluate the molecular responses of Pangasius nasutus to salinity exposure of varying concentrations. Juveniles of P. nasutus from similar breeding history (average size of 35 ± 0.54 cm and 152 ± 1.82 g) were obtained from a known source in Terengganu.

Effect of Cothurnia variabilis and Epistylis gammari (Ciliophora: Peritrichia) on Metabolic Rate of the Crayfish Cambarellus (Cambarellus) montezumae

Diversity, 2021
Peritrichs usually settle on the external surface and gills of crustaceans. However, their physiological effect on the host has not been studied. Respiratory rate is a susceptible index for some factors that affect an organism.

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 ...

Morphology and molecular phylogeny of four epibiotic ciliates (Ciliophora, Peritrichia) from farmed red swamp crayfish Procambarus clarkii Girard, 1852, with notes on the geographic distributions of related taxa

Water Biology and Security
Aquaculture of red swamp crayfish Procambarus clarkii is an emerging farming industry in China. As shown recently, one of the most significant diseases affecting the red swamp crayfish is caused by overabundance of epibiotic peritrichs, a group of ...

First record of epibionts peritrichids and suctorians (Protozoa, Ciliophora) on Pomacea lineata (Spix, 1827)

Brazilian Archives of Biology and Technology, 2006
This study made a survey on the ciliate protozoans from Peritrichid and Suctorian taxa, epibionts of Pomacea lineata (Spix, 1827) (Ampullariidae). Fifty mollusks were collected in places of irrigation ditches and shell was scraped with a scalpel and the ...

Symbiotic species diversity can explain invasion success and host–parasite system stability: The case of gammarid hosts

Ecosphere, Volume 15, Issue 7, July 2024.
Abstract A major current challenge related to invasions is the absence of a comprehensive theoretical basis for preventing the introduction of alien species and controlling their populations. By using a macroecological framework, we aim to examine patterns of symbiotic species diversity across native and invasive hosts to understand the mechanisms ...
