I would think it’s for the long term, that some survivors will reproduce and add to the forage diversity in the pond. I may be wrong….
Yes, this would be the goal. I've got some good places with high densities of rock piles/brick that would make good habitat and hiding places. If I can diversify the food chain, more baby bluegill will make it to 3-4 inches!
I was going to ask some questions about your crawfish habitat - glad to hear that you do have some habitat.
In my experience, for non-burrowing crawfish, they like "platy" rocks for the good crevices the best.
However, I think the most important thing for you to determine before stocking is the actual species of crawfish. The traits you want (not deep burrowing & good reproduction) are not necessarily the traits that the guys that sell edible crawfish are selecting for.
If you do find out the actual species available, then there are several experts on the forum that can evaluate their potential effects (both positive and negative) on your pond.
