Hosty - Beginning of spawn times even in OH will vary by as much as 3 weeks depending on southern vs northern OH (latitude). Also depth of pond can make a diference. Shallower ponds will warm faster and thus fish can begin to nest a little earlier compared to a deep pond or a pond with Aquashade. Ponds with Aquashade can warm up a little slower than a clear water pond.

Generally male northern strain of LMB will begin to build the nest around 60-63F. Egg laying will begin when average daily water temps are fairly stable in the 63F-65F range. It is generally thought that LMB usually do not lay eggs below temps of 64F. These temps occur in northern OH around early or mid-May. LMB in far southern OH can begin to spawn in late April during an early spring and daily ave air temps.

Bgill usually begin spawning right after the LMB are in late stages of spawning or just done spawning. Male nest building will begin when water temps are stable in the 64F-67F. range. The water temps for egg laying will then be stable in the 67F+ range. Egg maturation for bgill can occur up through August. Bgill will spawn in water temps up through the high 70'sF maybe even 80F.

Real early spawners are often driven off the nest by cold fronts.
