Changing the shape of a fish pond can greatly affect and increase its productivity. Because the edges are the most productive places, so if we expand the edges, we increase their productivity.
In reality, the shape of the pond must be adjusted to the shape of the land. This means that land determines form, not form determines land.
If you work in a natural form, you will get productive results with a small amount of time and labor.
Because we have more edges for the same amount of water, more trees and aquatic plants can be planted along that edge.
These trees and aquatic plants can provide:
• Feed for fish derived from fallen leaves and fruit.
• Shade for ponds that can reduce evaporation and regulate water temperature.
• Food for humans.
• Erosion control.
• Material for compost and mulch.
• Insects, birds and aquatic animals whose numbers will increase around the pond. They will naturally improve pollination and pest control and provide more food for fish.
• Healthier water.
Swimming is a good example for working with natural patterns and shapes, where just expanding the edge will benefit all types of farming and fish production.
Rice planted in a natural shape will be the most efficient.
On sloping lands, various patterns can use water during the rainy season.
Vegetables and soil can be protected and surface water can be drained for reuse.
Edges occur on land naturally, but can also be made by humans. All edges can be utilized and all utilization can increase production and diversity. All bunds have edges on both sides which are often not used for production. Even planting edge embankments with fruit and flower plants will provide many benefits. These benefits can include additional income, mulch, and incoming birds and insects. Because plants are on the embankment, they are also easy to harvest!
