Main objectives: Aplication of Daily Egg Production Method to estimate Sardine Spawning Stock Biomass. Estimate spawning area of sardine. Secondary objectives: Estimate egg and larva abundances for sardine, anchovy, mackarel and horse mackarel. Measure the salinity , temperature depth in the water column using ctd profiles.
