Is intensification a viable way for pond culture in Central and Eastern Europe
Journal Title: Aquaculture, Aquarium, Conservation & Legislation - International Journal of the Bioflux Society - Year 2011, Vol 4, Issue 5
Abstract
Today’s Central and Eastern European aquaculture is based on low production intensity pond culture dominated by traditional extensive and semi-intensive carp-based polyculture technologies, use of complete feeds in pond culture is not prevalent. Meanwhile pond culture in other parts of the World has gone through an intensification process, nowadays high-intensity monoculture technologies dominate in pond farming. Use of complete feeds and application of higher stocking rates have doubled-tripled yields compared to traditional extensive, semi-intensive farming methods. Economic analysis of Asian farms shows that intensification leads to increased profits per unit area and decreased profitability. The calculation of financial results of fish farming technologies of different intensity level show the same effect of intensification on viability in Hungary as in Asia: high feeding and stocking rate result in outstanding profit per unit area and decreased profit margin at the same time. Rising land prices (and rents), fees for usage of water, decrease in area-based subsidies can push the Central and Eastern European pond aquaculture toward intensification as high intensity fish rearing in ponds may offer good alternative for those farmers who have limited access to land (pond area) and water. However one must take the increased risks of high intensity and must have good managing abilities and farming expertise with special regard to water quality and biomass management.
