GIFT transfer risk management: Pathogen

Abstract

This risk analysis examines the pathogen risks associated with the proposed importation of fry of GIFT, a strain of Nile tilapia (Oreochromis niloticus) developed by WorldFish that is characterized by its improved growth characteristics, to Nigeria for aquaculture development. This analysis highlights the high level of risk management measures that WorldFish has either implemented or proposed. These risk management measures are among the biosecurity arrangements comprising world’s best practice for the introduction or transfer of live aquatic animals. This risk analysis considers 69 pathogens/pathogen groups (possible hazards) that have been reported globally from Nile tilapia. A number of these possible hazards are serious pathogens of Nile tilapia.
