  abstract = {{A} {L}agrangian model is used to simulate and quantify in the northern {H}umboldt upwelling ecosystem the processes of enrichment, concentration and retention, identified by {B}akun [{B}akun, {A}., 1996. {P}atterns in the ocean. {O}cean processes and marine population (sic). {U}niversity of {C}alifornia {S}ea {G}rant, {C}alifornia, {USA}, in cooperation with {C}entro de {I}nvestigaciones {B}iologicas de {N}oroeste, (sic) {C}alifornia {S}ur, {M}exico, 323 pp.] as being important for the survival and recruitment of early life stages of pelagic fish. {T}he method relies on tracking the positions of particles within water velocity fields generated by a three-dimensional hydrodynamic model. {S}imple criteria for considering particles as participating to enrichment, concentration or retention are used to derive indices of the three processes. {W}e analyse the spatial distribution of and seasonal variability in these indices. {T}he results are discussed in relation to anchovy ({E}ngraulis ringens) eggs and larvae distributions off {P}eru, and to a comparable study conducted in the southern {B}enguela upwelling ecosystem.},
