[Zbrafish] How many scientists and or labs use ZF?

[Caroline Parkin]

Hello all,

I'd like to know if anyone as an idea of how many labs there are in  
the world using zebrafish for research, or how many researchers there  
are?

I know this is likely to be a bit vague because of collaborators  
etc..but an order of magnitude that we can all agree on would be great!

And if anyone can estimate how many fish or fish lines even there are  
then that would be fantastic!

Many thanks,

Caroline
