Curva de seletividade em redes de emalhar utilizadas na captura de corimbatá, Prochilodus scrofa (Steindachner, 1881)

Santos, E.P. dosMota, A.Rodrigues, J.D.

The purpose of this paper is to determine the selection curve of gill-nets used to catch curimbatá, Prochilodus scrofa (Steindachner, 1881), according to Gulland (1969). The result is:  c* (L)=e-0.025(L-l.67m)2 Where: c* (L)= relative frequency of retention,            L = length of the fish, and            m = perimeter of the mesh.
