Migração da corvina, Micropogon furnieri, na costa sul do Brasil

Resumo

The correlation between the latitude where denser concentrations of the croaker (Micropogon furnieri) occurred and the month of the year were established in this paper. The unit effort production (kg/hour haul) was used as the concentration index and the hauls made within 30' were grouped in the immediate superior latitude. The croaker migrates along the Brazilian coast between 28º S and 33º S, according to the expression: y = 30.6 + 1.85 cos 30 (x - 2), where: y = latitude (ºS) x = 1, 2 .... 12 (months of the year)
