The bluegill generally begins its spawning career at one year of age, but has been found to spawn as early as four months of age under favorable conditions. [30] Anglers find spawning season to be a very successful time to fish for bluegills, as they aggressively attack anything, including a hook, that comes near. [13]
Bluegill: Lepomis macrochirus: Native to Colorado. Bluegill prefer to reside in weed beds and deep drop off points in lakes and ponds, as well as in slow moving streams and lagoons. They will usually stay near brush piles and under overhanging trees casting a shadow. Bluegill will feed on insects, larvae, worms, crawfish and small fish.
A lateral line is absent with 7–9 dorsal rays, 9–11 anal rays, 12–14 pectoral rays and 6 pelvic rays. During the breeding season, males develop prickly contact organs on the side of the body between the dorsal and anal fins, and on the ends of the last few dorsal rays, anal fin, and outermost rays of the pectoral fin.

These are seasonal structures, releasing their contents during the breeding season, and then being reabsorbed by the body. Before the next breeding season, new sperm ampullae begin to form and ripen. The ampullae are otherwise essentially identical to the seminiferous tubules in higher vertebrates, including the same range of cell types. [2]
The pumpkinseed x bluegill sunfish [1] (Lepomis gibbosus x macrochirus), sometimes colloquially referred to as hybrid sunfish or pumpkingill, [citation needed] is a hybrid between a pumpkinseed (Lepomis gibbosus) and a bluegill (Lepomis macrochirus). [2] They are sometimes found in lakes and ponds where both parent species are present. [2]

With courtship beginning sometime this month, mating season for these prehistoric reptiles takes place between May and June. Afterward, a female alligator will then lay a clutch of around 30 to 50 ...
Many animal species have specific mating (or breeding) periods e.g. (seasonal breeding) so that offspring are born or hatch at an optimal time. In marine species with limited mobility and external fertilisation like corals , sea urchins and clams , the timing of the common spawning is the only externally visible form of sexual behaviour.
