Freshwater Fish of America - Largemouth bass

Largemouth bass spawn in the spring, when water temperatures warm up to 59-75 degrees Fahrenheit.  When preparing to spawn, male largemouth bass will begin nest building behavior. They hollow out a circular pizza-sized nest in the bottom substrate of the lake to help protect the eggs when they are fertilized. This nest building attracts a female, who will release a portion of her spawn over the nest while

the male releases his milt to fertilize the eggs as they fall into the nest.
