24 Use of OC data for sustainable fishery Objectives : Simulate anchovy eggs and larvae backward evolution to reconstruct location and inter-annual variability of spawning areas Ichthyoplanktonic data: position, time, number of eggs and larvae, larvae length and otolith increments (proxy of age). Chl (r) encountered by the larvae in their backward travel: Only those individuals that travel within Chlorophyll-rich waters have a significant survival probability.
