Recommendation By ICCAT Concerning the Implementation of an Atlantic Ocean Tropical Tuna Tagging Programme (AOTTP) (14-02). Country/Territory Document type Regulation Date 2014 Source FAO, FAOLEX Subject Fisheries Keyword Marine fisheries Fishery management and conservation Monitoring Marine fishes Migratory species Data collection/reporting Sustainable use Research Abstract This Recommendation of the International Commission for the Conservation of Atlantic Tunas (ICCAT) concerns the Atlantic Ocean Tropical Tuna Tagging Program (AOTTP), a large scale tagging programme. This programme is carried out in order to improve stock assessments, to reduce the uncertainty in the estimation of the status of the stocks of tropical tuna in the Atlantic Ocean. The programme is based on tagging methodology to allow estimating the key-parameters of tropical tuna population dynamics, to reduce stock assessment uncertainties and to gauge the effectiveness of different fisheries management options and conservation and management measures.
