Iezer pilot site
Maintaining, and even increasing the biodiversity around the fish ponds, while at the same time continuing commercial fish production would require upgrading management practices. For example, grass and reed should be cut only after the breeding season.

The PES scheme
However, to recognize the real value of the biodiversity and the costs to the fishpond managers to sustain it, it is necessary to introduce more targeted payments.
That is why the WWF team developed and assessed how much it would cost to shift from pure profit-oriented to nature-responsible aquaculture business, also generating additional income from new opportunities, such as green premiums for nature-friendly aquaculture products or bird-watching tourism development.
A successful demonstration of extensive fish pond management in this pilot can have application for the many other fish ponds along the Lower Danube, in Romania as well as Bulgaria, Moldova and Ukraine, many of which are valuable wetland areas whose benefits extend far beyond fish production.
