Protozoan Co-Infection Drives Fish Mortality Event in Crete's Karteros River. [PDF]

J Fish Dis
ABSTRACT In August 2024, a significant fish kill involving hundreds of flathead grey mullet (Mugil cephalus) was reported in the delta region of the Karteros River, Crete, Greece. The investigation identified the primary cause of mortality as severe parasitic infections, specifically from the protozoan parasites Amyloodinium ocellatum and Trichodina sp.

The First Report of Cod Gill Poxvirus in Gills of Atlantic Cod (Gadus morhua L.) Suffering From Cardiorespiratory Disease. [PDF]

J Fish Dis
ABSTRACT Atlantic cod farming experiences renewed growth in Norway, and increased awareness is essential to address emerging diseases in this species. There are few reports on gill diseases in cod, and to date, no viral gill infections of cod have been documented. In this study, we collected samples from three sequential time points in summer 2023 from

Clinical Presentation and Pathological Effects of a Hydrozoan Bloom on Farmed Atlantic Salmon. [PDF]

J Fish Dis
ABSTRACT Largely unpredictable, gelatinous plankton blooms are a growing concern for the ever‐expanding mariculture industry. Recently, a bloom of a colonial hydrozoan known as Apolemia sp. was detected via a citizen‐science initiative, Nye.dugnadforhavet.no, in mid‐Norway in July 2023.

Looking for Greener Pastures: In Vitro Screening of Phytogenics for the Control of Sparicotyle chrysophrii in Gilthead Sea Bream. [PDF]

J Fish Dis
ABSTRACT The gill parasite Sparicotyle chrysophrii poses a significant threat to gilthead sea bream (Sparus aurata) aquaculture in the Mediterranean, causing considerable mortality and economic losses. As traditional chemotherapeutic treatments, like formalin, face growing regulatory restrictions, there is an urgent need for alternative control ...

Development of a Real-Time PCR Assay for Noninvasive Detection of Miamiensis avidus in Olive Flounder Aquaculture. [PDF]

J Fish Dis
ABSTRACT Miamiensis avidus (syn. Philasterides dicentrarchi) leads to high mortality and economic losses in olive flounder (Paralichthys olivaceus) aquaculture. In this study, we developed a real‐time PCR assay targeting the cytochrome c oxidase subunit I (cox1) gene of M. avidus to sensitively detect and quantify the parasite in seawater.

From Mud to Meat: Comparative Metabarcoding Reveals Two Different Evolutionary Paths to Carnivory in a Group of Meiofaunal Annelids. [PDF]

Mol Ecol
ABSTRACT Evolutionary transitions to carnivory represent profound shifts in feeding mode that are often accompanied by widespread changes in organismal function, behaviour and ecology. Such transitions have evolved numerous times among animals, and predator–prey interactions have been major drivers of animal evolution.

Bacterial Communities From Two Freshwater Aquaculture Systems in Northern Germany. [PDF]

Environ Microbiol Rep
Freshwater aquaculture in open systems utilises water from a natural source, which limits the control of water conditions. Water microbiome description could indicate water quality changes and be used for improving the farm management. Water microbiome composition did not change significantly between inflow and outflow water, although heterotrophic ...

Morphology and Molecular Phylogeny of Endosymbiotic Ciliates (Peritrichia, Mobilida) of Marine Invertebrates with Descriptions of Two Novel Species Urceolaria clepsydra n. sp. and Urceolaria bratalia n. sp. [PDF]

J Eukaryot Microbiol
ABSTRACT Mobilid ciliates are a morphologically distinct group of protists that form a wide range of symbiotic relationships with aquatic animals and includes three subgroups: Trichodinidae, Urceolariidae, and Polycyclidae. Trichodinids are best known for infecting fishes, whereas urceolariids infect diverse marine invertebrates.
