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

Resumo

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.
