Trichodinid Parasites on the Gills of Channa punctatus from the Wild and Cultured Environments in Sylhet, Bangladesh

Advances in Zoology, Volume 2015, Issue 1, 2015., 2015
Two trichodinid parasites, Trichodina cyprinocola and Trichodina pediculus, were acknowledged in the gills during a sampling preparation of thirty fish Channa punctatus from the wild and cultured environments. However, Trichodina pediculus was recorded only in one farmed fish.

Alpha-Tubulin and Small Subunit rRNA Phylogenies of Peritrichs Are Congruent and Do Not Support the Clustering of Mobilids and Sessilids (Ciliophora, Oligohymenophorea) [PDF]

, 2010
Peritrich ciliates have been traditionally subdivided into two orders, Sessilida and Mobilida within the subclass Peritrichia. However, all the existing small subunit (SSU) rRNA phylogenetic trees showed that the sessilids and mobilids did not branch ...

HISTOLOGICAL CHANGES ASSOCIATED WITH TRICHODINID INFECTIONS IN THORNY SKATES, Raja radiata DONOVAN [PDF]

Journal of Wildlife Diseases, 1975
Histological changes in the wall of the copulatory sac of normal adult female thorny skates, Raja radiata, were compared with those naturally infected with Trichodina oviducti. The parasites were associated with extensive defoliation of the copulatory epithelium and in some instances had penetrated the submucosa resulting in petechiae.

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 ...
