I did a post once back in March, about how to yield more guppies frys. i wasnt satisfied with my big female guppies only having 20+ frys at that time. thus i have research on the info on how to yield more frys.
factors that will influence the birth rates are water conditions, stress, diet, temperature, etc...
i mainly experiment with DIET because i knew i havent try a variety of food on them. Heres some results i wanted to share.
On 28/03/05 the female had 20+ fries (really dissapointed despite her size compared to others.)
i was mainly feeding with livebearer flakes, micro pellet when i first started out.
On 28/03/05 the female had 77 fries (excited!! it worked!)
i have change the diet to livebearers flakes, micro pellet, freeze dried tubifex worms and freeze dried blood worms.
On 26/05/05 the female had 118 fries (Satisfied at last! i have achieved my goal of hitting the numbers to the 100s)
i have change the diet to freeze dried tubifex worms and freeze dried blood worms, Beef Heart n Liver Tucker, tropical Tucker and frozen blood worms
i have noticed a significant Size gain and colour enchancement once started with with Beef Heart. the female is now huge and has shiny greenish scale body thus very healthy! i would recommend Beef Heart. if you want to put some SIZE on your guppies!!
