Several strategies exist for the breeding or propagation of cultivated fish. Selecting among them depends on the replica biology of the species, on native environmental conditions and on the facilities accessible.
Step 1: determine and separate the sexes.
The male and feminine of the African catfish are often simply recognized. The male includes a distinct sexual papilla, elongated and settled simply behind the opening. This sexual papilla is sometimes red at the tip for sexually prepared males. It’s absent in females.
A gentle prolong the belly of the feminine fish towards the reproductive organ gap releases the ripe eggs indicating the readiness and viability of the feminine.
A sexually prepared feminine includes a swollen, sometimes cherry-red reproductive organ gap. A read from the highest conjointly provides a feminine African catfish away since either aspect of the belly seems swollen.
Step 2: Prepare the feminine Catfish for injection
African catfish pituitary is often used for iatrogenic catfish breeding. Ways of removal and preservation of the pituitary don’t seem to be contained during this book.
For iatrogenic breeding of the African catfish, i favor to the employment the hypothesis, either freshly removed or plant product preserved. i like to recommend a quantitative relation of 1:1, recipient: donor id est. if the burden of the feminine fish to be iatrogenic is 1kg, the burden of the donor fish, male or feminine ought to even be 1kg for freshly removed pituitary.
However, for dried, preserved pituitary, i like to recommend a quantitative relation of 1:1.5 id est. recipient fish ought to be one and therefore the donor fish ought to weigh 1.5kg. i will be able to wish to state here that it’s not required that the donor fish ought to be one fish; it may be a pair of or three fishes with a combined weight of one.5kg or because the case could also be in weight.
A synthetic endocrine can even be used. Usually, the manufacturer can embrace the prescribed dose appropriate for The African Catfish breeding.
When you need to inject the fish, please don’t inject the fish on the sensory receptor. I in person like the syringe inform towards the tail of the fish. The fish ought to even be injected on top of the sensory receptor with the needle at forty five degrees to body of the fish.

I in person like the syringe inform towards the top of the fish. The fish ought to even be injected on top of the sensory receptor with the needle at forty five degrees to body of the fish.
Note that this method ought to be done whereas the fish’s head is roofed with a damp towel. This enables the fish to stay calm throughout the eighteen entire methods.
Step 3: combine totally and add recent, clean, water
The saline additional to the milt (sperm) keeps the sperm cell alive however not active. The saline makes it straightforward for the complete stripped eggs to be saturated with the milt. The next addition of recent, clean water currently makes the sperm cell active and motile.
It is the addition of fresh water that initiates the external fertilization method. This whole method of fertilization lasts for less than concerning sixty seconds. That’s why I powerfully recommendation that you just increase proportion fertilization by stirring the mixture throughout this sixty seconds.
