I've heard several different water temperatures over the years that initiate the spawn, tell me your version and why?
Are we talkin 'shallow' fish or 'spawning' fish???? I have caught 'shallow' fish very well in 55degree water & yet 'spawning' doesn't happen till upper 60's. <*)}}}><
Dont get focused to much on water temps, pay more attention to hours of daylight, and the moon phases. They make a huge push to bank on the full moon and the new moon! But 62-75 degrees is what we have all went by for years! Area of the lake and water color play a huge roll as well! EB
I just registered as a user today but have been watching the site about the last year and i really enjoy it. I have been catching crappie my whole life but never considered my self a crappie fisherman they would just be the fish that happened to eat my minnow under the bridge. I really just started looking for crapie last year while spawning and have fell in love!! So is the next new moon gonna be the start of the spawn or is the water still to cold?
It will be a push for the bank forsure. For the next 3 months this 1 encluded the crappie will make a mad push for the bank like EB stated during the full and new moon times. Take it mind that its all about temps when they start spewin their eggs, and its the moon phases that drives this trek for the bank.....Ranger

I have thought a lot about this subject over the years and after yesterday I am a little more convinced about my theory. I think all things mentioned above do factor in to when crappie spawn. I think water temp, water clarity, and moon phases all have a part in it. Now for a little different wrinkle than I have ever heard mention. Please don't laugh at me, this is just something for thought.
Every other animal that I can think of has a gestation period, that is how long they carry their offspring before they give birth. I know that we are talking about fish who are not carrying their offspring like humans, cows, dogs.......you get the picture. The females are only carrying the eggs and the fertilization process is done after she lays the eggs. Here is my question, is it possible that a fish needs to carry her eggs a minimum number of days before they are mature enough to be viable? Lets go back to other animals, the gestation period is a time frame, a pig is 114-118 days. Could it be that a fish has a time frame from the time she starts making her eggs in the fall until she lays them in the spring? The time frame would allow for the other conditions listed above to get right then she goes and lays her eggs. The way to explain a 2 month long spawn is not all fish will start making eggs at the same time. Some will start making eggs on this day and some will start 2 months later with most somewhere in between. Not all doe deer come in to heat on the exact same day, so is it possible that female crappie all have their own time frame when they start growing their eggs?
I am more convinced than ever that fish do have a time frame to carry their eggs. Yesterday creek water temps were 63-65 and hardly any fish in them. My theory why, the eggs aren't mature enough due to the lack of time since they began to grow. Water temps are not supposed to be 63-65 degrees in Oklahoma on March 14th. You take any other animal and introduce them to this world before their gestation period is up and they don't survive, unless we are talking about humans, where medical science has progressed. I don't think fish eggs are any different, they need a certain amount of time in their own element, then when water conditions are correct the female lays them.
Like I stated earlier, don't laugh this is just food for thought!!!

Odie - I am checking into your idea.
I checked with a biologist at ODWC today and his specialty was crappie. He said that photo period and water temp were the 2 critical factors. So water temp could be right but photo period is not right therefore the crappie will not spawn until these 2 factors are in line. Your thought about gestation period has merit but a live bearing mammal and a fish have different requirements.
What is "photo period"?
The duration of an organism's daily exposure to light, considered especially with regard to the effect of the exposure on growth and development.
For most animals the seasonally changing pattern of day length provides the most accurate year-on-year index of time and many fish use the increasing and decreasing components of this light cycle to coordinate development. In order to use light in this way, however, firstly the light must be perceived, secondly, day length change must in some way be measured and lastly, this information must be transduced into a suitable 'message' for integration by the newoendocrine cascade which initiates and then modulates development. Photoperiod is the ability of organisms to and use the body length as an anticipatory cue to time seasonal events in their life histories. Photoperiodism is especially important in initiating physiological and developmental processes that are typically irrevocable and that culminate at a future time or at a distant place; the further away in space or time, the more likely a seasonal event is initiated by photoperiod. A wide variety of animals from diverse take use the day length or photoperiod as an anticipatory cue to make seasonal preparations. Photoperiod is most useful in predicting environmental conditions in the future or at distant localities; photoperiod provides a go/ no-go signal that initiates a usually irrevocable cascade of physiological and development processes that cuminate in reproduction, dormancy and migration. Day length provides a highly reliable calendar that animals can use to anticipate and prepare for seasonal change. Unlike temperature and rainfall, day length at a given spot on earth is the same today as it was on this date 10 or 10,000 years ago.
All good answers, thanks for the input guys......... but I like Craig's answer best!
Thanks for the excellent explanation.
Cricket George did the biologist say what that photo period was?
Doug, this is in line with our discussion yesterday.Quote:

PHOTO PERIOD- Right after you land a real big one, generally da fishin' stops for a minute or two.......Dats called da "photo period!" :crazy:
INTERESTING....Ranger
I fished Oolagah yesterday and was having the same thought about water temp and photo period, the water was 62 and only a few fish were shallow. Also, yesterday was halfway between the new and full moons. Most were still out at 12-22 feet. I took time off from work to be there, was sure it was going to be great, but it was mediocre at best. Got to check out the new fish finder though. Ranger thanks for the tip on going straight to the SI. WOW, what a time saver finding brush!
Fishers - Not trying to hijack the thread, but the wallleye are all over the dam at Ft Supply and the temps is 59 degs. Walleye spawn starting at 46. My point is they should have already spawned but they are just starting. Water is too warm but the photo period is right and they are actively spawning.
This article cover three phases needed for crappie spawn. Water temp., Daylight hours
and Moon phase. I found it a good read. Cann't wait for water to settle so can
have good luck fishing.
