Aspectos biológicos de Stellifer stellifer (Bloch) na pesca artesanal do camarão sete-barbas, Armação do Itapocoroy, Penha, Santa Catarina, Brasil
Stellifer stellifer (Bloch, 1790) is one among the most abundant ictiofauna species which are caught by sea-bob-shrimp's artisanal fishery in Armação do Itapocoroy. Aiming to analyze its population structure, a total of 1459 specimens were collected from July/1996 to August/1997. Stellifer stellifer presented lengths varying between 3,7 and 17,7 cm, macroscopic sex differentiation started from 6,0cm, with a higher frequency of females (sex ratio = 1:3,2). The relationship between length and weight was Wt = 0,0073Lt3,1415. First maturation size was determined for females (7,5 cm) and males (8,1 cm). The fishery acts in a similar way on juveniles and adults. Stellifer stellifer presented two spawning seasons, one in spring and another in autumn.
