| Goal and objectives of the project | Determine the diversity of myxosporean parasites infecting economically important farmed fish along the south-central coast of Vietnam. Assess the impact of these parasites on host fish to provide a scientific basis for managing and preventing myxosporean infections. |
| Main results | - Theoretical results:
+ A total of 1,885 individual fish, separated by 30 species across 8 orders and 15 families, were dissected. Among them, 282 fish were found to be infected with myxosporean parasites.
+ Sixteen species/forms of myxosporean parasites, belonging to 6 genera and 5 families, were identified. These include 1 new species (Ceratomyxa chauvanminhi n. sp.), 3 species recorded for the first time in Vietnam (Kudoa javaensis, Kudoa parvibulbosa, Kudoa yasunagai), and 4 species previously recorded in Vietnam (Ceratomyxa binhthuanensis, Kudoa monodactyli, Kudoa scomberomori, Unicapsula andersenae), and 8 unidentified species (Ceratomyxa sp. 1, Ceratomyxa sp. 2, Ceratomyxa sp. 3, Zschokkella sp., Sphaeromyxa sp., Kudoa sp.1, Kudoa sp.2, Kudoa sp.3).
+ The infection rate of myxosporean parasites in the south-central region increased with rising temperatures in July.
+ Species of the genus Kudoa observed in this study did not cause inflammation at the infection sites. However, Kudoa yasunagai was found to cause body deformation in its host. Some fish infected with Kudoa spp. also spoiled faster than uninfected fish.
- Applied results: The results of this study significantly enhance the understanding of myxosporean parasites in fish in Vietnam. This research provides a crucial foundation for preventing and reducing the risk of diseases caused by myxosporean parasites in fish farms. |
| Novelty and actuality and scientific meaningfulness of the results | - This project discovered one new species and recorded three species for the first time in Vietnam. |
