Sustainable fish farming on the side of a mountain, surely no one would do that! Well for those with access to the local springs it has proved to be a great additional source of income. One young man, Hfisa Mpore’s son, is supporting himself through college from the sale of fish. Can you get any more successful than that?
LTT now have fish ponds at 3 locations, two ponds are at the Waangwaray Primary school providing them with an income and the water, rich in nutrients, is used to irrigate the crops.
Early experimental designs proved that brick and cement ponds are the most cost effective as they retain the water and last for longer than plastic sheeting which might last just a few years and absorbs the heat.
Once built the ponds fill with algae which keeps the water cool, injects oxygen into the water and hides the fish from the watchful eyes of passing birds of prey. The algae are good for the fish’s diet and increase their levels of Omega 3 which is good for us when we eat them. The community rarely get to eat meat and this source of protein is in great demand.
At the end of each year the ponds can be emptied and the mud, fish waste, dead baby fish and the rich water are used to improve the fertility of the soil in an area where leaching and soil erosion deplete the soil of minerals. We are growing fantastic tomatoes!!
The pond built at our office was designed with a chicken coop in the middle. The chicken droppings further enrich the water which then further enriches the soil. The chickens are also kept safe from predators.
