Pond Boss Forums INTRO Questions & Observations bass vs bg hatch timing

The best answer is "it depends". Spawning is a combination of photoperiod and temperature for largemouth bass. It's more about temperature for bluegills. In Texas, you'll often have bluegill spawns during bluebird, warm January days, then again in early March, before bass are even on a nest. But, they may even be spawning at the same time, with bass on solitary nests in 4-6 feet of water, with bluegill in nesting colonies in 6"-12" of water.
