Reproductive age of large mouth bass?

In the spring, when the water temp reaches about 62 f, the male comes close to shore and using his tail, fans out a nest on the lake bottom. The larger females come in a few days later, and spawning begins. The female deposits her eggs on the nest floor, where they are then fertilized by the male. The female leaves after a day or two, and the males stand guard over eggs until they hatch. He then guards the swarm of thousands of young, called fry, until their egg sacks are absorbed, which takes about a week. The young fish then disperse into cover like grass beds where they begin feeding on minute creatures in the water. As they grow, their prey size increases, they begin to take insects and minnows, and gradually begin to take small fish and crayfish. Adult bass eat many prey species, including smaller fish, small snakes, frogs, and sometimes even baby ducks. The young bass has a perilous life as only a small percentage live long enough to grow to adulthood. They are prey to many species when tiny, including large fish, turtles and birds. But those that do survive become one of the top predators in the environment, and the most sought after gamefish in the United States.
