Psiculture and aquaculture

Brazil and Paraguay have fishing potential as few countries in the world because of the quantity of waters.

Aquaculture

Today there are more than 850 fishermen between Foz do Iguaçu and Guaíra (at the Brazilian side of the reservoir). To these numbers can be added 130 families with more of 600 indigenous people along with settlements, small riverside villages, and amateur fishermen. The Itaipu Reservoir currently produces about 1,300 tons of fish being the most productive of the Paraná Basin.

Studies show that for 94% of the small-scale fishermen the monthly income is lower than two minimum salaries. With an average income of 1.5 minimum wage. However, the production of artisanal fisheries is limited by natural environmental conditions such as rainfall, water temperature, primary production etc, like any aquatic ecosystem.

It is within this context that Itaipu saw the need to create the project More Fish in Our Waters, which not only strengthens the fishing sector, but also encourages aquaculture as a sustainable means of income using a tank-net system. The initiative also intends to increase consumption.

That is how the Project arose of social inclusion, support, and valuing of the fisherman’s role. With this comes an attempt to improve the quality of life of the fishermen, squatters, small farmers, and Indian communities, streamline the reservoir fishing process, increase fish production, promote the sustainable development of aquaculture and fish farming in the BP3, produce food with a high nutrition value, as well as monitor and conserve biodiversity.

During a pilot phase, Itaipu made available to the fishing colonies more than 500 tank-nets, fries, and technical orientation. Initially around 200 fishermen participated of which many have grown to purchasing more tanks and become autonomous in their work.

A partnership between Itaipu, the fishing colonies, and the Environmental Aquaculture & Fishing Center at IAP resulted in the production of more than 50,000 fingerlings of Pacu to be put in the net-tanks. This production met the needs of fishermen, squatters, and the Indian village of Ocoy. Funai (National Indian Foundation) made a request in the name of the Indian community and 40 tank-nets were installed in that village and today it produces 12 tons of fish every year used to improve their nutrition quality with autonomy in production.
 
Fifteen fishing points with a collective use module were set up so that fishermen could have better hygiene conditions while working with the fish. The city administrations participated by installing city water and electric energy.

The Pacu is the fish species grown by the fish farmers, but others are being researched and tested to be produced.

Psciculture

The objective of the psiculture initiatives is to development techniques of artificial reproduction of native fish species, planting in the Itaipu reservoir and in other bodies of water to maintain the quantity and variety of fish.

In the reproductive period 2016-2017 a new annual production record of about 1,860,000 fingerlings was achieved. The construction of new nursery units is underway to increase the productive capacity, the first of which, the Alevinaje Station of Itabo, was inaugurated in January 2017.
 
In the ITAIPU Aquaculture Station, from the beginning of its activity until 2017, the reproduction of 12,073,000 (twelve million, seventy-three thousand) native fish, which were sown in different aquatic ecosystems, has already been achieved, mainly from the ITAIPU reservoir.
 
On the other hand, the professionals of the entity provide technical support to rural fish farmers of the region to handle native fish species.
