Validations of the daily periodicity of increment deposition in rocky intertidal fish otoliths of the south-eastern Pacific Ocean

Abstract

Daily deposition of otolith increments was validated for juveniles of 8 intertidal fish species in central Chile, Helcogrammoides chilensis, Helcogrammoides cunninghami (Tripterygiidae), Auchenionchus microcirrhis, Auchenionchus crinitus (Labrisomidae), Hypsoblennius sordidus (Blenniidae), Gobiesox marmoratus, Sicyaces sanguineus (Gobiesocidae) and Myxodes viridis (Clinidae). Validation was performed by Alizarin Red-S labelling followed by 6 days of growth.
