iv) The incidence of atresia during the spawning season also differs between species exhibiting determinate and indeterminate fecundity Fishes with indeterminate fecundity show a generalized prevalence of atresia and resorption of mature oocytes at the end of the spawning season (West, 1990; Greer Walker et al , 1994), while fishes with determinate fecundity, atresia rarely is generalized and, if present, it is distributed sparsely along the reproductive season (Hunter et al , 1992)
