I'm just starting to get some vegetation in the main pond. I'd imagine another year or so and it'll be ready for shrimp. This would just let me HOPEFULLY grow a bunch to stock at one time so that i have a better shot and getting them established. My only for sure source is to order from the Ebay guy. I will be going to Louisiana this summer fishing though and may stop by some creeks or flooded ditches and try to net some to bring back.
