Sex Ratio "Experiment"

[Doug Karpa-Wilson <dkarpawi at indiana_edu>]

I'm thinking that there's a lot of ideas about what controls sex ratios out
there, and lots of us would like to know!

So, I was thinking we should do an experiment together, or rather collect
data on the experiments we are already doing.

What I'm proposing is that volunteers do a few extra things to collect data
on the fish they are breeding and the resulting sex ratio and send the data
to me.  If there's a big and obvious pattern it should fall out
statistically in a hurry.

Here's how it'd work:

First, folks collect easy to collect data on hypothesized factors:
	mostly temp, pH, any others?
 at different times in their breeding process:
	spawning, incubation, hatching and say, 2 weeks of age.
and lastly,

sex ratio.
Then send the info to me, and I'll do my best to pull out whatever patterns
I can from what data I get.

Any thoughts before we start this?
