Will they do well in a SW michigan pond that just saw ice out now? How long to wait for water to warm up? No fish now, but hoping to build forage, add RES possibly predator way later. Will they overwinter? I'd love to order some.

I have 1/3 acre pond give/take, 8' at high tide (high ground water mark) and am thinking that 75-100 would do or maybe that is overkill for an empty pond?
