Abstract
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.
Highlights
The Serra Spanish mackerel, Scomberomorus brasiliensis (Collette, Russo and Zavala-Camin) (Osteichthyes: Scombridae) occurs in the Western Atlantic, along the Caribbean in Central Atlantic coasts and Southwest Atlantic from Belize to Rio Grande do Sul, Brazil (Collette et al, 1978)
Some aspects of the reproductive biology of S. brasiliensis have been studied throughout its geographical range
Studies conducted in the western coast of Maranhão, Brazil, indicate that the reproductive period of S. brasiliensis extends from June to November, with the participation of 3 year old females which attain sexual maturity at 411 mm and 4 year old males at 443 mm (Lima, 2004)
Summary
The Serra Spanish mackerel, Scomberomorus brasiliensis (Collette, Russo and Zavala-Camin) (Osteichthyes: Scombridae) occurs in the Western Atlantic, along the Caribbean in Central Atlantic coasts and Southwest Atlantic from Belize to Rio Grande do Sul, Brazil (Collette et al, 1978). It is an important fishery resource of the Atlantic Ocean and is a major component of artisanal fisheries in northern and northeastern Brazil, with high commercial value. In coastal waters of Rio Grande do Norte, females of S. brasiliensis attain gonad maturity at 280 mm and males at 345 mm of total body length (Lima et al, 2007)
