Population management has many parts. We tend to focus more on adding fish to counteract a perceived problem. Often a better course is to focus on total mortalities. It is an easier approach. Just take out the right # , type and size of fish to go the other direction. The end result of adding to many fish either through addition or failure to harvest (catch , seine , trap etc) to augment natural morts is to cause water quality and fish health problems (poor condition or disease). Removing small to med sized BG may be a better option. Management is about using all the tools to reach a goal.
