Koda,
I hate to see a post go unanswered, so I'll take a shot at yours.
I'm experienced with two kinds of shad for pond forage: threadfin and gizzards. Threadfin do not survive water temps below about 42 degrees, so you would probably not expect to see any survival next spring in your pond. However, they would make a very good snack, albeit expensive ones, for your LMB.
The gizzards have been noted to grow to large sizes in small ponds without adequate predation. I have them stocked in a 4 acre pond with HSB and LMB and they are doing fine, but would hesitate at stocking them in 1/2 acre pond because of their tendency to overtake small waters with many large gizzards.
If you do a search on topics on threadfin and gizzard shad, you will find several posts, mostly on threadfins. Not many folks on here, other than myself and a few others, have stocked gizzard shad in their ponds.
