Thanks for the link, Tony. The second to last paragraph pretty much sums up what I have come to believe through personal experience and reading articles like his. Daylight hours seem to get them in the mood and temperature seems to affect when they actually do the deed...

The late Dr. Willis, and his thoughts on photo period and spawning. Scroll down for the article on springtime and spawning.

I've shared this topic through my Facebook group, The Palmetto Fly.
I've trimmed out the esoteric elements, since they're not for everyone.
But that's how it goes. I just thank you all for your drive and input.

Leo, I am pretty aware of the scientific method, I was raised by a veterinary pathologist (avian diseases specialist) and a PhD research microbiologist working for CDC, so I heard all sorts of competingzoological theories at the dinner table. I started down the science path myself originally majoring in chemistry and even working as a lab tech for a while (real exciting stuff; certifying nutrition labels on livestock feed). Anyway, I have a lot of exposure to scientific minds socially, academically and professionally. 

I meant no disrespect in questioning where this theory stands in the scientific community. Some theories, like gravity, are widely accepted and you won't be taken seriously by most if you discuss alternatives. This theory doesn't seem to be as well known or accepted.

I do have some skepticism about it, mostly due to the dependency on animals sensing changes in climate. They have shown remarkable abilities at seeming to predict weather and seismic events that will occur in the near future, but most of what I have read on sensing climate has been negative or inconclusive. The other fly in that ointment is that I (and most of the scientific community) believe that the climate is currently being affected by forces other than nature.

I still think it has been pretty well documented that activity will start at about the same date in the same locations from year to year but spawning will vary more widely and seems to be largely driven by temperature. It sounds like what you are looking into is a possibly explanation for minor variances within that than something completely different.

Andy, like all other universal theories which became logical and widely accepted facts in practices, based on hundred and thousand years old assumptions, these actually have logic background scientific basis. I was quite pessimistic at first, but allowed logical digging of scientific studies to reinforce the sounded arguments.

B.W., yes, these forces do have an overall influences on spawning and maturing cycles, not only in fishes, but also in plants. Aquatic creatures, those who dwell near the surfaces, under photo-period influences near photo-dependent plants, exhibit similar triggers for maturation to spawning/reproduction.

Localized regional conditions do contribute to the maturation and reproduction/spawning cycles. But what truly forces the fishes to react to an early/late maturation/spawning cycles? It's now no longer the regional conditional influences. It goes up even higher.

B.W., great to have a scientific mind to discuss with. To the rest, sorry if we went a bit overboard.

Thanks, Leo. These are sufficient for now. I was able to track down a few others to read based off your links to get an idea of what you are talking about.

So are you saying these forces have overall "spawning (reproductive cycle) affects," or are you more targeting them as "spawning (cycle) triggers?" After reading more, my first impression is that localized conditions would still continue to be the dominant "force/trigger" in any given year (in determining bluegill spawning), but variations of/over time might play out more according to these global forces.

Would it be fair to say these theories are in their infancy and not yet widely known or universally accepted?

There is a lake near me where the largest average creels for bass in 2015 will probably occur in the next 2-3 weeks because they have pretty much every year whether we get 40s or 80s in mid March. But when they bed has varied much more widely. I think the photo period (hours of daylight) is what triggers this because I don't think they have calendars.They start packing it on whether it is cold or hot but don't start the spawn until the water warms up.

Sure. Here are some blurbs, and I'll search for published documents later. I drowned the published articles in a 16TB storage somewhere, including their publication links and notes.

Planetary shift and fishery blurb

Planetary effects on animals (short blubs)

Planetary shifts (biotic state vs conditions) on multispecies and n...

I'll check the references by universities on the global nodes for the photo-periods vs climatological shifts due to planetary shifts as I pull the info up from my storage units. But in the meantime:

Spawning is affected more than just photo-periods, or climatal temperature shifts. Yes, these two play their roles, but these roles are a part of a greater picture that we only recently become more aware of. There are more to the spawning trigger than meets-the-eyes. I'm still trying to study more on the subject since I'm extremely interesting in pushing the envelop for optimal genetic growth potential for fishes and plants, creating a diversify aquatic-terra agricultural practices without destroy the ecosystems (a dream in the making).

Leo - I'm trying to get a better grasp of what you are referring to from your explanation below, but coming up short. Could you possibly reference a paper or study that might better explain what you are talking about? A search for "global seasonal shift" comes up with little, so perhaps there is a different terminology? From most of the literature I've read on spawning in subtropical climates (Mozambique, Puerto Rico, etc.), photoperiod and water temp still play an important role to a degree, but spawning tends to be protracted, in some cases extending to a period covering half the year. Are you referring to other external environmental forces? For example, some bass in these climates seem to use seasonal heavy rain events (water level changes) as a key trigger for spawning, but again, only during a certain period of the year (photoperiod and/or water temp.). While in equatorial saltwater, corals key their reproductive efforts to full moon phases at the beginning and ending periods of the monsoon season. Might that be an example of what you are talking about?

The two best days for fishing is when it's not raining... And when it is.
