Insights into mucosal and systemic immune responses of African catfish, Clarias gariepinus, to chilodonellosis: A natural infection study

Journal of Fish Biology, Volume 107, Issue 4, Page 1323-1334, October 2025.
Abstract A natural parasitic infection with the external ciliate protozoan, Chilodonella hexasticha, was recorded 3 days post‐transportation (PT) in the gills and skin of African catfish (Clarias gariepinus). Infected fish displayed behavioural changes and typical signs of infection.

Nile Tilapia (Oreochromis niloticus L.) Cage Aquaculture in Africa: Potential Threats to Congeneric Fish Species and Advances to Detect Escapes

Aquaculture, Fish and Fisheries, Volume 5, Issue 4, August 2025.
ABSTRACT Cage fish farming, a recent development in aquaculture, has enhanced fisheries production due to its higher stocking densities than traditional pond and open‐water systems. Although it can enhance production, the system can pose biodiversity threats when there is an unintentional or intentional release of stocked fish into the wild.

Flatfish lesion detection based on part segmentation approach and lesion image generation

Journal of the World Aquaculture Society, Volume 56, Issue 3, June 2025.
Abstract The flatfish is a major farmed species consumed globally in large quantities. However, due to the densely populated farming environment, flatfish are susceptible to lesions and diseases, making early lesion detection crucial. Traditionally, lesions were detected through visual inspection, but observing large numbers of fish is challenging ...

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.

Journal of Eukaryotic Microbiology, Volume 72, Issue 2, March/April 2025.
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.

Towards sustainable water disinfection with peracetic acid in aquaculture: A review

Reviews in Aquaculture, Volume 16, Issue 4, Page 1621-1646, September 2024.
Abstract Peracetic acid (PAA) has a long history as an efficacious and eco‐friendly disinfectant. It was first synthesised in 1902, and since then a wide range of applications has been developed in various industries. Aquaculture is a more recent industry wherein the potential of PAA is significant.
