Collecting live rock in bc

[ScubaSteve]

If you put cold water rock in a warm tank you're going to have a big die off and a huge spike. You also won't be getting any of the beneficial bacteria. As stated above, the rock here is very dense and not really suited to for use as Live Rock.

As for the legality, I don't recall the exat law I think it is OK to take a reasonable quantity as long as it is not from an "established habitat" (ie. the BC equivalent of a bustling reef) and it is not from a protected or Crown owned land. Collection of wildlife on the other hand is a lot sketchier. I've been tossing around the idea of a cold water tank for a while so I was looking into this some time back. I believe the Ministry of Fish and Wildlife has a site dedicated to answering these exact questions.
