Characterising the spawning habitats of sardine from the northern coast of Spain in april 2008

Abstract

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.
