Sea urchin relocation

[Maggy Nugues]

Dear list members,

I am contemplating an experiment to look at the effects of increased herbivory on Caribbean reefs. 
To do this, I would like to move some Diadema to increase densities on some reef areas. But I am 
worried that after relocation, the urchins might not remain on the reefs. Has anybody tried relocating 
urchins & How might you ensure they remain in the area?

Thanks for your help.
