Catfish Spawn

Catfish­ w­ill generally wait to spawn until the water temperature reaches at least 66 degrees Fahrenheit. Therefore, for the catfish, geography is destiny. Because water in southern latitudes warms first, catfish-spawning season begins in the south first. Most species spawn in the late spring or early summer. Obviously, it takes longer for a lake to heat up than it does for a shallow backwater to do so. Remember, too, that not all fish in a water system spawn at the same time. Any part of a lake or river may have catfish at one of three stages: pre-spawn, spawn, or post-spawn. And of course, there will be fish too young to spawn. Catfish mature at three to four years of age, though females may mature sooner. Catfish nest in cavities. The male creates a nest, and then lures the female there to spawn, no doubt inviting her to view his etchings. After the female has deposited a mound of sticky yellow eggs, the male fertilizes the mass. He drives the female from the nest, preferring to guard the eggs himself. During the six- to 10-day hatching period, the papa catfish eats little. His work is to prote­ct the eggs and keep them aerated and free of sediment by constantly fluttering his fins to circulate water. He continues to protect the young until they leave the nest.
