Abstract

Snappers are edible fish of great commercial importance in Panama since their meat is highly appreciated for its excellent texture and taste; all species in the family are commercially exploited. Lutjanus peru (Nichols and Murphy, 1922) is an important species for the artisanal, industrial and recreational fisheries. The main objective was to describe at microscopic level the cycle of ripeness of the females of the red / silk snapper. Samples of histological cuts were prepared with the Hematoxilin-Eosin's dye routine. Due to the presence of oocytes at different stages of maturation throughout the year, this histological review allows us to deduce that Lutjanus peru has a spaced reproduction period that coincides with the rainy season, with a peak in June and most likely another spawning period towards November and December. Red snapper’s, has a reproductive period spread with a maximum gonadal maturation in June. As we find evidence that the total length (Lt) of catches has decreased and that most of the captured females are young specimens, this implies the need to improve management measures.
