Hapas are cages, usually made from fine mesh that can be set up in any shallow pond, canal or ditch. They are fixed to poles pushed into the pond bottom and are only suitable for shallow water (less than 1.6m) with low water flow rate and level fluctuation. All spawning, sex reversal and nursery operations at Nam Sai are carried out in hapas fixed to bamboo poles that provide flexibility in high wind. They are cheap, durable and quick to set up a matter of minutes. Harvesting of fish is simple using a bamboo pole to confine the fish in one corner. They are easily cleaned by scrubbing with a hard brush whilst washing with pond water.
Hapas are not suitable for growing fish to market size, as they are fouled quite quickly and water exchange is insufficient to maintain very high stocking densities. Nevertheless, there is sufficient oxygen supply for moderate stocking densities (0.5 to 2 kg per m3) and ammonia and nitrite build up is not a problem. Natural food is also available in hapas, as phytoplankton and other small food particles can pass through the material and the material itself provides a surface for algal growth. This can be enhanced by using chemical fertiliser to promote phytoplankton growth, a technique particularly useful with tilapia.
Grading, vaccination and handling of fish is made easy with hapas. They are often fitted inside rearing tanks to make harvest of fish simple.
*Can be used to farm fish fry
*Hapas can be used for other aquatic animals, such as prawns, shrimp, frogs, fancy fish, etc.
