A study on spawning of bull frogs (Rana catesbeiana) using induced mating

60 male and female bull frogs were injected with a total dose of 1, 3, 5 or 7 mg crude pituitary extract (CHE)/kg body weight, administered at intervals of 6, 12 or 18 h. The incidence of spontaneous spawning was 25-100% in treated frogs vs. 0% for untreated controls, the best results being obtained after treatment with 5.5 or 7.7 mg CHE at intervals of 6 or 18 h.

Variation in reproductive success within and between the sexes was investigated for 2 yr in bullfrogs, R. catesbeiana. Number of successful matings/male ranged from 0-4/yr; number of successful matings/female ranged from 1-2/yr. The polygynous mat...
