Largemouth bass generally spawn in spring as water warms. In Texas, TPWD says spawning begins around 60°F and may start as early as February or as late as May depending on location. Across the broader range, timing shifts with latitude and local conditions.
Is 60°F the spawning temperature?
It is a useful field cue, especially in warm-region fisheries, but it is not a universal biological switch. Bass in different parts of the same lake can be at different stages because protected coves, shallow dark-bottom areas and exposed shorelines warm differently.
Where do largemouth bass build nests?
Males generally choose relatively quiet shallow areas and clear a circular nest. TPWD describes Texas nests as commonly occurring in roughly two to eight feet of water, but water clarity, slope, lake level and habitat can move nests shallower or deeper.
The male does most of the parental care
After fertilization, the male guards the eggs and then the fry, attacks potential predators and maintains the nest. A bedding male is therefore performing active parental care rather than simply occupying shallow water.
How many eggs and how long until they hatch?
TPWD gives a broad Texas range of roughly 2,000 to 43,000 eggs. Eggs commonly hatch in about five to ten days in Texas, with development rate strongly influenced by temperature.
Why nest guarding matters to fishing
Removing a guarding male can expose eggs or fry to predators. In a 2012 study of nest-guarding largemouth bass, 24-hour abandonment was 3% among controls, 33% after catch-and-release angling and 90% after a simulated tournament treatment involving longer removal/displacement.
Do all bass spawn at once?
No. “Pre-spawn, spawn and post-spawn” can overlap within a single reservoir because individual fish and different sections of the lake warm and progress at different rates.
