Carp – King of Christmas or National Treasure?

By: Remigiusz Panicz

Poland is the biggest carp producer in Europe, and it is expected that in 2019 production will rise up to 21 000 tonnes. Based on available data carp sales increase every year, but without a doubt the peak is observed a week or two preceding the Christmas period.

More than half of Poles declare their willingness to purchase carp during this period. Remarkable is also the fact that during Christmas Poles consume as much as 90% of the annual fish consumption. Such situation is unique in the World. In Polish tradition, carp is a fish that reigns on Christmas tables, although other species also appear on it (e.g. herring, salmon, trout, lean fish).

Consumers value carp meat for its taste and aroma, but we should bear in mind that carp meat has also a high nutritional value. It’s a source of wholesome and easily digestible protein, health-promoting fat (essential fatty acids), vitamins and minerals. Sales are dominated by carps in live form or as carcasses, and increasingly as chunks or fillets.

However, growing consumer awareness and the systematically increasing pace of life forces producers to search for new processing methods and to create more attractive products. Thanks to this, soon carp will be present in stores throughout the year. To overcome this challenge, Polish carp farmers will have to intensify and modernize production methods.

One solution could be combining traditional breeding in ground ponds with closed aquaculture systems. This system is currently being tested by the ZUT team together with other GAIN project partners. In addition to the breeding aspects, shortening the production cycle, supported by precision aquaculture (use of sensors, biomarkers, Big Data, IoT), the assessment of turning both by-products and side-streams into valuable secondary materials – while increasing profits and minimizing the environmental footprint – becomes crucial.

There are several hundred carp-producing farms in Poland, which cover over 80 000 hectares of pond area. The fish farming sector employs over 5 000 people, with approx. 3 000 directly in carp farming. These farms may be interested in solutions developed in GAIN, especially those considering water availability reduction due to climate change.

Ponds are also a natural habitat for various birds, mammals and other animal species, which contribute to improving the environmental biodiversity and its attractiveness for tourism. Ponds are also important in water management – thanks to water retention they improve water balance in our country.

All of these aspects are a testament to carp being not only a King of Christmas but a National Treasure as well!

The Future of Aquaculture

By: Remigiusz Panicz

The Future of aquaculture’ was the overarching motif of the international conference held in Kudowa Zdrój, Poland between 25 and 27 September of 2019. Fish farmers, scientists and other stakeholders had a unique opportunity to participate in the science-grounded lectures and follow-up discussions both devoted to the aspects and problems of the aquaculture sector

Among these current and future concerns, are animal welfare, the diversification of aquaculture, certification models, climate change and diseases risk. GAIN’s partners Remigiusz Panicz, Jacek Sadowski and Piotr Eljasik, from ZUT introduced participants of the conference to the GAIN project, its objectives and provided its vision on common carp eco-intensification.

This species, whose culture has a long tradition in Poland, currently struggles due to numerous factors: water scarcity, unfavorable policy, and market uptake. The freshwater farmed fish sector seeks for viable solutions to keep carp farming on a profitable level.

During the conference an interesting voice was raised regarding precision aquaculture: a direction which is unavoidable in order to cope with the aforementioned factors. Aspects of macroalgae culture in Polish coastline waters was also presented and discussed: this interesting idea is developing into a new project being launched in Poland this year.

Numerous aspects of circular economy in the Polish aquaculture sector were also raised and discussed openly: energy efficiency, regulations, and management of by-products and waste streams, and pertinent questions related to carp meat supply throughout the whole year.

The eco-intensification and precision aquaculture work developed in GAIN, coordinated with the efforts of stakeholders, might bring solutions for the future of carp farming in Poland.
