Most catfish hatcheries in Nigeria take 24–45 hours for the catfish eggs to hatch. After the catfish eggs hatch, a small yolk sac hatchling is born. The yolk will be absorbed in 3–4 days, and the larvae will be further nurtured in the ponds.
How many catfish eggs survive
The number of catfish eggs that survive varies depending on several factors, including the species of catfish, the water temperature, the quality of the water, and the presence of predators. However, only a small percentage of catfish eggs generally survive before maturity. For example, a female channel catfish can lay 3,000 to 50,000 eggs.
What is the color of a catfish egg?
Catfish eggs are usually pale yellow when they start developing. However, the color can vary depending on the species of catfish. For example, the eggs of catfish are pale yellow, while the eggs of blue catfish are more reddish-brown.
Characteristics of catfish eggs
- Catfish eggs are likewise clear, allowing you to observe the growing embryo. The embryo will begin as a little black dot, gradually becoming larger and developing eyes, fins, and other traits.
- Because catfish eggs are sticky, female catfish will adhere to a substrate like rocks or plants. This helps keep the eggs in place and keeps predators away.
- The eggs will hatch in around 3-5 days, depending on the kind of catfish. Catfish fry are newly born catfish. Because the fry are so little and delicate, they must be protected from predators.
How to fertilize catfish eggs
1. Set up a breeding tank.
The breeding tank should be large enough to accommodate the female catfish and her eggs. It should also be filtered and aerated to provide clean, well-oxygenated water.
2. Condition the water.
The water in the breeding tank should be conditioned to the same temperature and pH as the water the female catfish uses. You can do this by using a water conditioner or adding a small amount of aquarium salt.
3. Fertilize the eggs.
Mix the milt with the saline solution, then evenly pour the mixture into the bowl of peeled eggs.

To ensure a successful hatching of catfish eggs, monitor the eggs closely and ensure the water quality is good.
