This document presents the results of the analysis from sardine (Sardina pilchardus) egg densities in
relation to environmental (temperature, salinity) and geographic (longitude, depth) variables. Data were
obtained from the SAREVA0408 ichthyoplankton survey conducted by IEO (Instituto Español de
Oceanografía) in April 2008. Quotient analysis, temperature-salinity plots and time distribution for eggs
per stage of development, were employed to study spawning habitat of the sardine off north Spanish
Atlantic, Cantabrian waters and south of the Bay of Biscay.
