You'll want to choose where and what kind of pond you're going to use depending on the fish you want to grow, the environment you're working within, and the set-up you intend to implement. A nursery pond will need protection from flooding or toxic runoff, and access to clean water and energy or power to run filters or aerators. How will you manage the water within the pond? A liner may be necessary, as well as sediment or debris traps to manage any pollutants or waste.
What is the temperature of your area and the water within? This has a major impact on the fish that you'll choose to stock your pond with. The enclosure you intend to use will also be better or worse for different kinds of fish. This can range from keeping baby fish separate via baffles, cages, pens, or another kind of mesh that allows the fish to grow within a larger body of water while being protected. However, this makes adjusting and measuring the conditions of the nursery area more difficult than it would in an isolated enclosure.
