On Thursday Fisheries Minister, Marcelo Crivella is to visit the National Institute for Space Research (INPE) to learn about the Environmental Monitoring Integrated System (SIMA), which will be adopted from next month in Furnas Reservoir in southern Minas Gerais.
This initiative will make it possible to set a model for impact monitoring and assessment for fish farming in tanks-nets installed in public reservoirs.
In addition, it will assist in the performance of the Good Management Practices (GMP) and collaborate with production and environmental management of aquaculture parks.
The system, developed with domestic technology, involves six probes for monitoring water quality in four arms of the Furnas Reservoir, where fish farming takes place.
In the future, the system will be adopted in all the existing aquaculture parks, the Ministry of Fisheries and Aquaculture (MPA) reported.
"This system offers great importance for national aquaculture, as it will allow the continuous environmental monitoring and will make the Ministry’s proposal as to environmental license exempt for aquaculture parks viable in the case of those implanted up to 0.5 per cent of the water depth of the reservoir," stated Maria Fernanda Nince Ferreira, MPA Secretary of Aquaculture Planning and Management.
Currently, Brazil has about 200 large reservoirs that can be used for the production of fish in tanks-nets.
As it was explained by the coordinator and researcher at the Brazilian Agricultural Research Corporation (Embrapa), Fernanda Sampaio, Furnas will receive a larger probe, developed by INPE more than 15 years ago that can be used to perform environmental monitoring and is capable of transmitting data via satellite.
Five other smaller probes were specially developed for monitoring parameters of interest in aquaculture. By means of these floating platforms, they will be placed in the waters of aquaculture parks of Guape 1 and 2, in the municipality of Guape.
The smaller probes are capable of recording water quality parameters: pH, dissolved oxygen, temperature at 15 depths, conductivity and turbidity.
The probes will show the influence of aquaculture on the environment and of other productive activities in the region, such as agriculture. Furthermore, the MPA hopes they become a management tool for farmers.
The Ministry allocated an investment of BRL 1.4 million (USD 633,500) for this project and Embrapa invested about BRL 400,000 (USD 181,000).
