(effective breeding population) is most useful if the hatchery manager can control breeding to some degree, usually through application of PIT tags, induced spawning, . MATING IN FROGS. In almost all frogs , eggs fertilization happens outside the females body instead of inside.. The female releases her eggs and male releases his sperms at the same time . In order to make sure that the sperms reach the eggs ,the male and female get into the mating posture called .
