Abstract

Ovaries of salema Sarpa salpa (Linnaeus, 1758) presented hard structures easily seen macroscopically. Histological analysis suggested that these structures correspond to masses of hydrated oocytes, which are remnants of an incomplete or unsuccessful spawning event. The generalised linear model (GLM) showed that the presence of cysts was significantly affected by month. The fact that these structures appear frequently and in high prevalence may suggest that they are related to or associated with the reproductive strategy of this species.
