How many catfish hatch at a time?

The number of catfish hatchlings can vary significantly depending on the species and environmental conditions. For example, a single female channel catfish can lay between 2,000 to 30,000 eggs in a single spawning event. However, not all eggs will hatch, as factors like water temperature and oxygen levels play a crucial role in the hatching process. Ultimately, the number of hatchlings that survive can be much lower than the number of eggs laid.
