There are two main scallop banks populations in northern Peru: Lobos de Tierra Island (LTI) and Sechura Bay (SB). Despite a continuous, intense relocation of seeds from LTI, the natural bank population still persists there. To understand this, we studied larval connectivity between LTI and SB using the first invertebrate larval transport biophysical model developed in the region. Larval local retention were 2.4% and 1.57% on average at LTI and SB respectively, while larval transport from SB to LTI was 0.02% on average and 0.07% in the opposite direction. Both larval retention and larval transport increased with spawning depth and were highest in austral summer. Two main larval transport paths from SB to LTI were identified, resulting from a combination of horizontal mesoscale circulation patterns and vertical flows. Potential management implications for these natural banks are discussed. specialized Peruvian scallop Larval transport Biophysical model Marine connectivity Marine reserve Humboldt Current System PEROU PACIFIQUE LOBOS DE TIERRA ILE 032 036 144 142-155 2019 1385-1101 https://www.documentation.ird.fr/hor/fdi:010074943 10.1016/j.seares.2018.12.003 1385-1101 [F B010074943] https://www.documentation.ird.fr/hor/fdi:010074943 https://www.documentation.ird.fr/intranet/publi/2019/02/010074943.pdf Accès réservé (Intranet de l'IRD) IRD - Base Horizon / Pleins textes 2019-03-06 2025-02-24 fdi:010074943 fre
