I know it would be temporary.. but my thought is that hopefully the juveniles would grow fast enough that they would become too large for a tadpole to nail. Maybe not.

Yes, edible - I've been wanting to try this since I got out of college (took aquaculture courses there) but never had the opportunity. Now I do and am excited about what I *might* get out of it. Saw some freshwater shrimp in the freezer section of Walmart the other day, nice looking ones too. Hoping for 16-20 per pound (fat guys) with a 120 day growing season. Also saw a report on studies from the University of Nebraska regarding the use of old hog barn pits for growout tanks (do these shrimp taste funny to you??? \:o ).

At the end there might be either a HUGE shrimp boil or a freezer full of fat ducks :p

Thanks for the thoughts \:\)
