Fry – The first stage of fry is when a newly hatched walleye is still living on the egg sack after birth. It has not yet developed an air bladder and is not yet feeding on food in the water column. Walleye at this stage of life have been stocked to the lake in large numbers and used to grow advanced fry.
Advanced Fry – The second stage is when fry are no longer living on its egg sack and is feeding on food, usually plankton, small bugs, and young insects, in the water column. They have developed an air bladder and are able to swim. These fish are used by LCWA to raise walleye fingerlings in its four ponds.
Fingerling – The third stage is when fingerlings have grown to a length of 2-1/2 to 3 inches. At this point, they are usually feeding on larger food, such as young minnows. They are used for stocking purposes. It is extremely difficult to raise walleye beyond this stage because they become very carnivorous as they continue to grow; survival rates drop radically.
