UMT MOOC: Ornamental Fish Culture - Topic 5: Ornamental Fish Breeding - Live Brearer

In fish breeding, the first step is to identify the male and female of the fish species. From there, only we can pick a pair to breed. Then we have to learn what type of breeding characteristic of the fishes we want to breed. Next, we need to setup the breeding tank and condition the pair of fish so it can mate and breeding in optimal environment condition.

The fish group we going to discuss is livebrearer. Popular livebrearer are Guppy, Mollies, Platy, and Swordtail.The mating and breeding characteristics are similar to mammals where the male uses its gonopodium (reproductive organ which looks like a special anal fin) to channel its sperm to the female's fertile eggs in its body. Upon successful mating, the embryo will stay in the female body until it reaches juvenile stage and the female will gave birth.

To breed Guppy, use 3 females and 2 males (not sure why this gender ratio was used, it's not mentioned in the slide). Put some aquatic plants and when the fry have grown into juvenile fish. These plants can served as additional diet, places to hide, and substrate. If the female Guppy have silver black colour on its stomach, that is an indicator that the female Guppy is going to give birth. The video below shows the step-by-step guide on breeding Guppy.
