Hi Noura,
we use different kinds of breeding technique here. depends on individual preference actually…
one method is to put all the breeders in a boxed screen mesh(usually nylon or plastic net)wherein the box is eleveted about 2 inches from the floor of the pond.the size of the pond is about 4 x 8 feet.. and the size of the screen box is about 2 x 4 feet. we place the breeders inside and feed with high protein diet. The fries just drop underneat the screened box and swim outward, usually to the side of the pond. Most live-bearers attack or eat their fry, or anything smaller than them for that matter. This is the reason for the box..so that the adults will not eat or attack the smaller fish.
Others use plastic straw to serve as hiding place for the fries. We seldom use aquatic plants as they harbor parasites. Plastic straws bundled together serves the purpose and is easier to clean. They scoop out the fries twice a day (early morning and late afternoon) and put them in separate tanks. The size of the fry or juvenile must be of the same size or else they attack the smaller fish, so usually 2 weeks collection from the breeding tank of fries is of the same size.
Another method is isolating female in 1/2 gal tank and waiting for them bear the fries..like a “delivery room”. this is tedious work as you have to separate the mature female from the fry once the mother is finished with the process of delivery or else she attacks the fries. Once separated, you place the fry in a separate tank.
Here, the male guppies commands a high price that the female. the females are usually kept for future breeding. Our breeding ratio is usually 10 female to 1 male. We only get about 40% male. This has no “scietific proof” but someone tried a ratio of 1:1 and he came up with about 80% male. So if we follow the same procedure..maybe if you decrease the number of male breeders, you might decrease the number of male offsprings??!! We have opposite problem actually.
