Pond Boss Forums MANAGING AN EXISTING POND Evaluating and adjusting fish populations First fish kill

Does YOY mean the fish are less than 1 year old. If so they are. I figure these were hatched as late as October. Now that you mention it, most of these fish were very skinny. I have not fed since the begenning of November so these fish were on their own. The fish were found on the shallow end of the pond but the wind was blowing in that direction.
