A few emeralds will live to spawn in their 5th summer age 4. In the pond setting you may see slightly longer life spans and less predation pressure maybe to age 5 or even 6. YP may be feeding on abundant shiner fry, small crayfish, and sinking pellets during the summer.
Great pictures. I would call those definitely emerald shiners. Note the distinct, definite position of the dorsal fin well posterior to the pelvic fin origin. Also note the distinct falcate anal fin a character of emerald shiner and not of the common shiner. On these last pictures you can clearly count the anal fin rays which are 11 and the common shiner has 8-9 anal fin rays.
