Status quo of commercial aquaponics in Czechia: A misleading public image?

Abstract

Aquaponics is the integrated production of aquatic organisms and plants. The majority (>50 %) of nutrients sustaining optimal plant growth in aquaponics is derived from waste originating from the feeding of aquatic organisms kept in aquaculture. Currently, aquaponics is more popular as a hobby rather than for commercial-scale production. We used long-term data verification to present a qualitative in-depth study of the regional development of aquaponics. We used a questionnaire and in situ interviews to record farm information. In addition, we conducted an Internet search to explore the aquaponics sector and examine the trend in online interest. In contrast to the non-production part of the industry representing 71 % of the Internet search, commercial aquaponic farms only accounted for 2.7 %. In total, annual aquaponic production in Czechia peaked at 3 000 kg of fish and 276 kg of plants, produced mainly by one large-scale aquaponic farm that has been in long-term operation. Using Google Trends, we found a positive trend in online interest. However, a developed online “industry” with a positive image creates an unrealistic awareness of aquaponics. On the basis of this exemplary case, a similar trend can be expected in other countries.
