There were no significant differences in specific growth rate, body weight gain, gonadosomatic indices (of males of females) fecundity and in the number of fry produced per female per day between guppies fed with feed A, B, and C. Male guppies fed with feed containing 45% and 50% protein developed significantly heavier testes (P<0.05) while females fed with 45% dietary protein produced significantly larger eggs compared to eggs produced by females fed with feed A and C (1.44mm ± 0.008, 1.54mm ± 0.01, 1.48mm ± 0.01 for feed A, B and C respectively; P<0.05)

If larger eggs produced by the females are of better quality with different composition and if males with heavier testes could produce a greater number of viable sperms, a feed containing 45% protein could be recommended for both male and female brood stock of guppy which would be cost effective and convenient at farm level
