Abstract

Seriolella violacea Guichenot, 1848 (Centrolophidae), commonly known as the palm ruff, is a commercially important endemic fish species in the Eastern South Pacific, the capture of which has significantly decreased in recent decades (Oliva, Parker, Miranda & Martínez 1996; Chirichingo & Velez 1998). This epipelagic resource is vital to small scale fishery activities and is one of the most consumed fish, by regional human populations. Providing alternative production methods and studying the factors that affect the health of this species are important for achieving its successful maintenance under reared conditions.
