Fig. 2 in Modeling energy flow in a large Neotropical reservoir: a tool do evaluate fishing and stability

Fig. 2. Relative biomass (2a) and relative catch (2b) of the main species of the ITAIPU-2 model, with increasing of fishing effort. Fishing effort = 1 is equivalent to that registered in 1998. This value was multiplied by 2, 3 and 4, in order to get other fisheries scenarios. Simulations made in Ecopath with Ecosim (Subroutine: Run Ecossim, module: Results).
