Abstract
This paper reviews past and present modelling of tropical tunas in the Atlantic Ocean. In the early seventies modelling of the stock was conducted for the most important species, yellowfin tuna, using the Schaefer production model and multigear yield per recruit and simulation approaches. In 1984 a multigear multispecies bioeconomical modelling made it possible to evaluate the changes of yield per recruit expected from seasonal closures of the tuna nurseries areas. However the internal dynamics of the stocks (tuna migrations) and of the fleets were neglected. Consequently past models did not allow any comprehensive understanding of the dynamics of the fleets. The present good knowledge of tuna migrations, the detailed log books, the economic and environmental data, now makes it possible to develop a new generation of tuna fishery models which will help to monitor the fisheries more efficiently in the future.
