Popis:	The Serra Spanish mackerel, Scomberomorus brasiliensis is an important fishery resource of the Atlantic Ocean and is a major component of artisanal fisheries in northern and northeastern Brazil. Ovarian development and spawning period of S. brasiliensis were investigated using both macroscopic and histological techniques. Mean monthly values of GSI and ovarian maturation indicate that the main spawning period occurs during the rainy season.A Serra, Scomberomorus brasiliensis, é uma espécie marinha de valor comercial do oceano Atlântico sendo um maior componente de pesca artesanal no norte e nordeste brasileiros. Desenvolvimento ovariano e época de desova de S. brasiliensis foram investigados utilizando-se técnicas macroscópicas e histológicas. Valores mensais médios de IGS e maturação gonadal indicam que a época de desova ocorre durante o período de chuva.
