หัวข้อ: A practical guide to pathogens in seabass and sea bream aquaculture
เริ่มหัวข้อโดย: Nicaonline ที่ พฤษภาคม 29, 2020, 01:50:50 PM
A new diagnostic manual that covers the main pathogens in seabass and sea bream aquaculture has been made freely available today.

Developed as part of the MedAID project by a group of experts from Croatia, Denmark, France, Greece, Italy, Spain, Tunisia and Norway, it is intended for everyday use by fish farmers as well as diagnostic laboratories dealing with diseases of both species.

Titled the Diagnostic manual for the main pathogens in European seabass and gilthead seabream aquaculture, it was conceived to provide up-to-date guidelines to enable a harmonised approach to the health challenges caused by viral and bacterial pathogens in farming these species. The parasitic diseases are omitted in this document to avoid overlapping with the H2020 project ParaFishControl, which deals solely with diagnostic procedures for parasitic diseases.
The authors note that, although many publications exist on the diagnostics of aquatic animal diseases, there is a lack of reference diagnostic methodologies for seabass and gilthead sea bream, the main finfish species produced in the Mediterranean.

This gap is considered an obstacle for further development of the industry and for designing and coordinating harmonised health management strategies in the different regions of the basin. A possible reason for this constraint may be that seabass and sea bream are not listed as susceptible host species for the notifiable pathogens listed in the current EU legislation, or in the list of diseases notifiable to the OIE, which generates a lack of approved diagnostic methods. Although not notifiable, only viral encephalopathy and retinopathy, due to its importance, is included in the OIE Diagnostic Manual for Aquatic Animal Diseases.

The new MedAID manual contains detailed instructions on the sampling, shipping of samples, handling with samples in the diagnostic laboratory, requirements for bacteriological and virological laboratory as well as on diagnostic procedures for the most important diseases. Particular attention was paid to the mortality caused by unknown etiology and to the interpretation and reporting of the laboratory results. The authors are hoping that it will contribute to the solving of the aforementioned problems in Mediterranean marine aquaculture.
