The activity of processing the Hypophthalmichthys nobilis specimens from Bârca acumulation (Iasi) was studied during a period of 3 years and revealed the fact that by processing the less valuable fish breed, there is registered a consistant profit. The fish paste, practically, increased the fish farm productivity by over 20% reaching 58.9% and it had a contribution of 28.9% to 49.5% to the total profit. By creating a brand for the farm's products, a new niche market has been reached and an unexpected profit was obtained during the winter, when the farm recorded only maintenance expenses.enCC BY-NC-SA 4.0https://creativecommons.org/licenses/by-nc-sa/4.0/freshwaterpastepolycultureproductivityArticle
