The course is designed for 25 participants with a university degree. It is intended for veterinarians and other aquatic animal health professionals, with or without previous formal training in epidemiology, but involved in delivering aquatic animal health services in either the private or public sector.
The course will be held at IAMZ-CIHEAM in Zaragoza from 25 February - 1 March 2019, in morning and afternoon sessions.
3 December 2018
The deadline may be extended for candidates not requiring a visa and not applying for a grant if there are free places available.
Registration fees for the course amount to 500 euro. This sum covers tuition fees only.
Candidates from CIHEAM member countries (Albania, Algeria, Egypt, France, Greece, Italy, Lebanon, Malta, Morocco, Portugal, Spain, Tunisia and Turkey) and candidates participating in MedAID project may apply for scholarships covering registration fees, or scholarships covering the cost of travel and full board accommodation.
Candidates from other countries who require financial support should apply directly to other national or international institutions.
