Tuna biomass (skipjack and bigeye tuna) variability over the period 1998-2019 simulated by the Spatial Ecosystem and Population Dynamics Model (SEAPODYM).

Here, we provide the unfished biomass dynamics (i.e. without considering any fishing). For each of the four tuna species we provide both the total biomass (adults + juveniles) and the larvae abundance.

This model is described in :

The downscaling is described in :
