Largemouth bass inhabit clear, vegetated lakes, ponds, swamps, and the backwaters of pools, creeks and rivers. Largemouth bass prefer spawning areas with a ?rm bottom of sand, mud or gravel. Adult largemouth bass use submerged aquatic vegetation as cover to ambush prey and juvenile or young largemouth use aquatic weeds, tree limbs or submerged log or stumps as cover to escape predation. Dissolved oxygen is also an important hydrological condition essential to largemouth bass habitat.  Largemouth bass grow best in temperate to subtropical waters, with northern fish taking many more years to reach a given size than fish living in warmer southern waters. 

Adult largemouth bass feed on ?sh, cray?sh, and frogs. With the young feeding on crustaceans, insects, and small ?sh.  Largemouth bass are voracious eaters, with many different animals becoming prey to this fierce eater. Even terrestrial animals like snakes and mice. Some largemouth bass can be cannibalistic too, just like the northern pike. Largemouth bass normally do not feed during spawning or when the water temperature dips below 41 degrees Fahrenheit or above 98.6 degrees Fahrenheit. 

Common length for largemouth bass is 16 inches with the longest recorded specimen being 38.2 inches.

The heaviest reported weight for a largemouth was 22 pounds. Largemouth bass maximum reported age is 23 years. 

Largemouth bass spawn in the spring, when water temperatures warm up to 59-75 degrees Fahrenheit.  Male largemouth bass, when preparing to spawn will begin nest building behavior by hollowing a circular pizza sized nest in the bottom substrate 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.  

Females are periodic spawners, spawning with several males in different nests over a period of a few days.  The males will guard the eggs and small transparent fry. The fry will remain hidden in the nest substrate for several days until they become pigmented and disperse into the pond to search for food after a few days post hatch.  The fry remain in a school to protect themselves from predation and will begin feeding. The fry initially feed on small copepod and cladoceran zooplankton. When the fry reach 1.5 to 2 inches in length they will begin to feed on insect larvae and become piscivorous.
