Check the current pH of the pit water. The reading should indicate if the pH is out of range for rasing fish or shrimp. pH should be between 6 and 9.0 and preferably not higher than 8.5.
Consider raising fish for your consumption or custom grow-out of larger sizes for pond stocking. Good candiatates would be yellow perch, bluegill, hybrid bluegill. You could raise trout in the winter; stock as soon as the water temp droped to 65-68F. You could have family angling events in the pit for recrational harvest of fish then do a final harvest by seining after drainig the water down. Research water filtration using aquaculture techniques. Keep in mind that the more fish you stock the more waste they produce, and more filtration that will be needed. Install back-up power to prevent fish kills during power failures.
