Seedlings planted

A wooden frame was built to carry a clear plastic roof. If the grow beds fill up with rain, it can disrupt the nutrient levels in the water, so it's best to protect the beds as much as possible. Many people build a greenhouse over their beds and fish, to protect them from the weather and extremes of temperature. However, we live in the subtropics and although we do have the occasional bad storm, extremes of hot and cold are very unusual. Fifty or so silver perch fingerlings were then purchased from a nearby hatchery and seedlings were planted on the same day (April 7) and we were away!
