The normal weight of M. salmoides is one kilogram; however, certain largemouth basses have gotten weights of over ten kilograms. Males usually do not surpass 40 cm, while females can reach up to 56 cm in length. The largemouth bass has a large, slightly sloping mouth. Its body is slender to robust, slightly compressed laterally, and oval in cross section. The corner of the mouth extends past the eye, hence its common name. (Bailey, et al., 2004; Boschung, et al., 2004) Immature Micropterus salmoides feed on zooplankton and marine insects. As they grow their diet shifts to crayfish …show more content…

Males begin their investment by making nests as well as protecting these nests from invaders. Once the eggs hatch, males remain with their young and defend them against all predators. This continues usually for about a month. (Becker, 1983; Cooke, et al., 2001) In the morning, largemouth bass tend to be very mobile and remain in deep waters. During the afternoon, largemouth bass are mostly sedentary and are usually found near a larger structure in deep water. As the sun goes down largemouth bass become very mobile and move into shallow water. They remain lively throughout the night with a minor decline in movement. Movement of bass usually correlates to movement of prey species. The home ranges of largemouth bass are relatively small and overlap with each other. Despite this, there is very little agonistic behavior between individuals and most interaction occurs during spawning. (Demers and McKinley, 1996; Sammons and Maceina, 2005) Largemouth bass mating system is polyandrous, meaning the female mates with several males during one breeding season. During the breeding season, each male makes and builds a nest in shallow water. Nests are usually very basic in design. Once the nest is created a female swims near, and following an act of courtship, she lay her eggs in the nest. (Becker, 1983; Dewoody, et al.,
