Former Kubin Dr. Yomrs Diaz Ernandes raises flies of a black soldier whose lips can be used as food for fish, which brings more money than any benefits that he had previously achieved than the practice of a medical profession.
In the rural workshop on the outskirts of Havana, flies Diaz are sponsored. As in most parts of Cuba, equipment and tools that he uses are made manually from everything that he can assemble.
For a decade, the initiatives in France, the Netherlands, the UK and other countries invested in the education of flies of a black soldier, the Reuters news agency reported.
This fly is defined as destructive waste, and its luminous are powered by urban and agricultural biological waste, forming a dynamic mass of larvae with a high protein content, which can be treated for use for animals and pets feed.
Diaz explained that the increase in the flies of a black soldier reaches production at a very low price.
He said: “A friend of this idea gave me this idea in 2019 after I practiced medicine in internal medicine for more than 20 years, and this expanded my horizons.”
This year, they witnessed how the United States inserted new sanctions on the communist rule of Cuba, in addition to decades of the trade embargo.
Then the epidemic began to paralyze the local movement of tourism and industry, and the weak effectiveness of the public sector led to a slowdown in recovery, which led to the fact that the Caribbean state suffers from the lack of liquidity necessary for the import of everything. This was followed by economic stagnation for a long time.
Last year, the government began to study the advantages of increasing flies in order to compensate for a sharp decrease in livestock imports. Diaz said several Cubans launched their own small projects.
Last year, Diaz sold 300 kilograms of larvae for freshwater fish farms in Cuba at a price of 450 PZZO per kilogram (about $ 3.75 at an official exchange rate when the dollar is available). He hopes to sell 1000 kilograms this year. He will make a profit that much exceeds that he could earn as a doctor, but he says that his main task is to achieve Cuba’s stability.
He said: “transfer this garbage to the protein and to (food) gold for animals and waste in fertilizers. We also contribute to environmental protection. “
