PALMA G, Sergio  y  ARANA E, Patricio. Simple methodology to identify sex of sea urchin Loxechinus albus (Molina, 1782), and its application to fishery-biological studies. Investig. mar. [online]. 1996, vol.24, pp.123-130. ISSN 0717-7178.  http://dx.doi.org/10.4067/S0717-71781996002400010.

Sex identification of the edible sea urchin Loxechinus albus (Molina, 1782), is difficult if not done in a laboratory, therefore most of the studies on this resource does not consider sexes separately. This paper describes a simple methodology to identify sex of the sea urchin, enabling the estimation of fishery-biological parameters separately for males and females. Through the described procedures, it is possible to separate by sex the length frequency distributions from samples taken without differentiating males from females. This procedure becomes specially useful when sexes show differences in growth or mortality.
