Life cycle and mating behavior
Madurez | Reproducción | Puesta | Huevos | Fecundidad | Larva
Observed presence of two distinct waves of developing oocytes in a study indicates a group-synchronous ovary in this species, thus, subsequent spawning during the same breeding season may occur though unverifiable in the same study (Ref. 57432).
