The Pisciculture project arises in the community of Pomis Jiwet in the framework of the search for a sustainable food solution throughout the year, which is complemented by traditional fisheries and agriculture. It is projected that production of this fish farm will provide a considerable amount of protein for the livelihood of the families of the community.
The joint work of experienced fish farmers from northwestern Argentina and water management specialists from the University of La Plata, developed an integrated fish farming and fishing project of pacú and other species.
An important objective in addition to developing fish farming in the area, is the formation of technicians that can amplify and pass on this knowledge to other communities.
Fish farming is an activity that presents the opportunity to integrate with other disciplines, such as poultry farming and agriculture, generating a wider, diverse and synergistic ecosystem, connecting the various activities of the community.
In general terms, the area has natural technical feasibility for the development of this productive project and these communities have long been related to fishing.
The predominant species within the fish ecosystem is the pacú (Myleus pacu), a native species that the Chorote community knows as “Tak’am”, which has been missing for several decades from the waters of the Pilcomayo River. It has omnivorous characteristics, with a high rate of protein conversion and high resistance to a variety of oxygen and temperature conditions, making it a great choice for its easy handling and implementation in the area.
This ecosystem is fulfilled with other species such as the boga (Leporellus pictus) and the shad (Prochilodus lineatus) also native to the Pilcomayo River, generating beneficial and complementary associations.
Several members of the community were trained in Clorinda, Formosa, on the management of water and pool operation, the different processes in the rearing of fish from fry to adults, and the subsequent work to efficiently take advantage of pacú.
Infrastructure and operation
As from the collective effort of the Pomis Jiwet community, and all the people involved, the following necessary infrastructure was carried out for the project:
- Consolidation of a dam, with its respective pump and filter, for the harvest of rainwater and / or a possible overflow of the Pilcomayo River.
- A pool with a capacity of 1,855,800 lts for breeding.
- Three youth and adult breeding pools of 355,200 lts.
- Two pools of 57.500 lts. for the breeding of fry.
Engineers from the National University of La Plata have designed a closed system of capture, collection and subsequent circulation of water in the pools, with pumps, filters and aerators that optimize the use of water and provide the necessary conditions for the breeding of freshwater fish. Solar panels have been installed to ensure the operation of the system taking advantage of the high availability of the solar arc in the region.
The pools have been developed with local clay material and waterproofed with PVC geomembrane, weather and high radiation resistant to prevent the filtration of
nitrates and nitrites to the flaps, as well as to improve and efficiency flow rate, with a possible discharge to the irrigation system of orchards.
