Short summary
This Paper endeavors to find or understand the relationships between tuna landings and dramatic events as El Niño in the Central Eastern Pacific and visualize the impact of long term oscillations, like the Pacific decadal Oscillation (PDO). Here for the first time tuna landing, fish efforts and the El Niño indexes (ONI and MEI) are correlated to find how the later affect the tuna fishery. Special attention has been put on tuna landings in Ecuador.
