Default Counting frogs

Changing the theme slightly - Is it true or have I dreamt that frogs and
toads don't co-exist in the same pond ? I have the frogs and frogspawn, but
would like to introduce toads to the garden too. I think they have a bad
press, but I like them.

Does anyone have any idea how to count the frogs in a pond?

For example - I counted 36 frogs in the pond today - does that mean I
have 36 frogs? Or have I got nearer 50?

can one tell form how much spawn there is? Does each female lay one
batch or more than one batch - eg if I have 20 batches of spawn have I
got 20 females or could it have been laid by,say, 5 females?

How many females does each male mate with? I presume once he's
fertilised one batch of eggs, he won't just sit on the sidelines, he'll
see if he can find another female.
