1.4 Declaration on sustainability of the described Technology

Nee

Comments:

A high water table is favourable for digging shallow water wells for irrigation of cropland which increases production during the dry season.

2.1 Short description of the Technology

Definition of the Technology:

Fish farming supported by availability of water is considered as profitable enterprise in Northern Uganda. Farmers use areas with either high water tables or swamps to locate the ground water recharged fish ponds and water for fish production and crop irrigation during the dry season.

2.2 Detailed description of the Technology

Description:

Fish farming is a sustainable land management agricultural practice promoted by farmers on medium sized farms in Northern Uganda, where ground water supply in wetland is used to recharge at least three adjacent fish ponds for fish production during the wet and dry season with each pond established measuring 50 m long x 20 m wide and 1.5 m depth with the following inputs hoes, spades, panga, wheel barrow, feeds and labour. The sides of the ponds are grown with grassy vegetation to stabilize soil, as well as feed the fish. It is, therefore imperative that farmers who want to invest in such sustainable land management practice first seek professional advice from extension agents or from other experienced farmers, on post-harvest fish handling and preservation. In Northern Uganda, fish theft and poisoning are also rampant, especially where ponds are not properly guarded or fenced. The most costly aspects of pond fish farming include pond excavation, laboratory testing of water and surrounding soil properties; procurement of fries especially tilapia, fencing and procurement of fish feeds. The average cost of establishing each pond is approximately US$428; while putting fish firies establishment goes for an average of US$ 71 per pond.
It is important to note that at the beginning the capital investments are high; these include paying for construction and buying fish fries to put in the ponds. However, in the long term the benefits exceed the costs. This is because fish farming is a high value enterprise with potential to provide household food, nutrition and income security.
