A nursery pond desgin can be as simple as you want it to be, as long as the baby fish are given a safe, clean, and maintained place to mature into fingerlings. This is the most critical stage of development, with a considerably high level of mortality. This is directly related to the quality of their nursery environment, including food quality, water makeup, available oxygen, and other environemental considerations. This requires some level of frequent maintenance.
The value of an isolated environment is in the ability to finetune and focus on one tank or pond. Temperature, food and waste concentrations, and the amount of chemicals and oxygen in the water all can be more closely measured and adjusted when focusing on one kind of fish. The fry within a nursery pond are typically within one stage of life, with one set of preferred conditions.
