These guidelines illustrate good practice for broodstock handling and management using practices that are suitable for small-scale operations. This document is also available in Oriya.

Self-recruiting species are defined as aquatic animals that can be harvested from farmer managed aquatic systems without regular stocking. This may include indigenous or introduced, small or larger species. Identified self-recruiting species in the Red River Delta includes exotic species (tilapia), large (snakehead, walking catfish and river catfish) and small (Anabas and Carassius auratus) indigenous fish species and non-fish species (freshwater shrimp and crabs).

Any pond can be used to grow fish, but a pond that is dug specially for fish culture usually has a regular shape, a flat bottom with a slight slope along its length. When deciding where to locate a new pond, you should consider the landscape, land use, soil texture (15% clay is best for pond construction and water holding), water supply (consider quality, quantity and seasonality), security (from theft) and convenience (maybe close to your house).

Fish culture is where people own and look after a stock of fish. This might involve regular stocking, fertilisation and feeding, protection from predators and disease and taking care of the environment.

When selecting a good place for a pond, an engineer may seek advice from local people, a biologist or an economist. It may be difficult to find an ideal site but it is necessary to look at the available sites before the work on pond building begins – so that it holds water, does not collapse or cost too much and will not waste effort and money. There are lots of things to think about before finally recommending a site.
