Bruce, Can you make the Outdoor PBR larger to result in 1 turnover a day? Increasing the size and reducing the flow rate should allow you to raise just about as many fish and maybe more fish. Is space the limiting factor for the design?. Hopefully Cecil can respond to provide turnover rate per day of his original trout pond adjacent to his house.
To keep herons off the islands you could pound short stakes around the perimeter of the islands then lace string or monofilment 10"-20" high around the stakes.
Bruce I think DIED means to bring the liner out of the pond and place it in a shallow trench that surrounds the shoreline of the pond. Backfill the trench with dirt and then if desired you could place pavers or stones on top of backfill to help hold backfill in place. This would be especially imortant if trench is shallow.
