Article Synopsis
- - This case study examines the prevalence and impact of the parasite Caligus clemensi on European seabass and flathead grey mullet at a marine fish farm, finding seasonal peaks in infestations during winter and spring respectively, along with significant declines in the warmer months.
- - Morphological and molecular analyses confirmed C. clemensi as the identified parasite, highlighting its physical traits and genetic characteristics, while also revealing a strong immune response in infected fish indicated by increased interleukin-1β levels and severe tissue damage upon evaluation.
- - Environmental assessments showed water quality issues linked to local oil activities, including high levels of suspended solids and dissolved ions, which likely contributed to the conditions favoring parasite growth and reduced fish resistance.
Article Synopsis
- The study focused on a disease outbreak in European seabass and flathead grey mullet at a facility in Egypt, characterized by infestations of caligid copepods and secondary bacterial infections.
- A variety of analyses confirmed the caligid species as Caligus clemensi and identified Vibrio alginolyticus as the secondary bacterial infection, with notable antibiotic resistance found in the bacteria.
- An effective treatment plan was established that included hydrogen peroxide baths and natural compounds, successfully eliminating the copepod infestations and improving the health of the fish.
