Fish Farming Project

With the collective effort of the Pomis Jiwet community, the foundation and the contribution of our sponsors and volunteers, we began with the construction of an artificial lake of 23 million liters of water, with a 6 meters deep chamber and its respective pump and filter, for the harvest of rainwater and/or a possible overflow of the river Pilcomayo. We have built:
  • A pool with 1,855,800 liters capacity for fish breeding.
  • Three pools of 355,200 liters.
  • Two pools of 57,500 liters for fingerling breeding.
The connections between the pools by a closed water system with pumps and filters to optimize the use of water and provide the necessary conditions for the breeding of freshwater fish have been designed with specialists from the National University of La Plata. They have been waterproofed with synthetic flexible polyvinyl chloride (PVC) geomembranes, resistant to weathering and highly resistant to U.V. radiation. 0.75 mm to avoid the filtration of nitrates and nitrites to the underground water tables, as well as, improve and streamline the flow rate, with an eventual discharge to the garden irrigation system. For that purpose, they have been waterproofed with synthetic flexible geomembranes of polyvinyl chloride (PVC), resistant to weathering and highly resistant to UV radiation of 0.75 mm to avoid the filtration of nitrates and nitrites. This also helps enhance the water flow, with a discharge to the vegetable garden irrigation system. The predominant species will be the pacú (Myleus pacu), known in the area by the Chorote communities as "Tak'am", disappeared for several decades from the waters of the Pilcomayo river, which along with species such as the vulture (Leporellus pictus) and the shad (Prochilodus lineatus), the latter will be extracted from the Pilcomayo River, seeking to generate beneficial and complementary associations within the pools. The Pacú is a native species that disappeared from the riverbed of the Río de La Plata basin. It presents omnivorous characteristics, and its feed conversion ratio and resistance to the variety of oxygen and temperature conditions make it easy to manage and implement in the area. The production of this fish farm is expected to provide a considerable amount of meat for the livelihood of the families in the community, and tackle the lack of fish that seasonally leaves the communities without this key resource. In general, the area presents natural technical feasibility to the implementation of this productive project, and the cultural positioning of local communities that have been related to water and fishing since ancient times. In terms of trade goods, fish are an accepted source for the barter economy, which is very common in the area, and facilitates the acquisition of different products with a cooperative production model. An important objective in addition to developing fish farming in the area, is the training of technical cadres who can amplify and transmit this knowledge to other communities.
