Subject: Spawning induced by iodine?

I have heard rumours recently that some species of fish have been 
induced to spawn in aquaria by the addition of 0.5-1% potassium iodide 
to the water. I assume the logic for this is the regulation of endocrine 
hormones by iodine & therefore presumably, the ultimate release of 
pituitary hormones. This is therefore an alternative to pituitary 
hormone injections.
Does anyone know anything about this and/or does it sound feasible?
