Hungary Case Study – Carp Ponds

Potential effect of manuring on the microbial community of semi-extensive carp ponds in Hungary


Case study description
The Hungarian case study of the TAPAS project carried out by Szent István University. We will investigate:

The use of chemicals is not characteristic in the semi-extensive carp producing ponds. However, the antibiotics content of the manure used to increase the productivity of the system neither controlled nor known. This manure usually from pig or poultry farms, where the antibiotics usage is generally high. No information is available regarding the effect of the residual antibiotic content of the manure on the European carp ponds.

Background and importanceThe usage of chemicals are not characteristic in the semi-extensive carp producing ponds, However, the antibiotics content of the manure, used for increasing the productivity of the system neither controlled nor known. This manure usually from pig or poultry farms, where the antibiotics usage is generally high. No information is available regarding the effect of the residual antibiotic content of the manure on the European carp ponds.
 
 
 
Aims

  • To assess the effect of manuring on the microbial community of carp ponds.
  • Modeling the potential effects using ERA-AQUA.

Methods

Water and sediment sampling (temporally also structured) in three localities with different manuring regime (Site 1: (Gyótapuszta) No manuring due to located in water quality protection area; Site 2 (Buzsák): Usage of cattle manure; Site 3 (Akasztó): usage of poultry manure). Sampling Analytical screening of antibiotics. qPCR screening the enrichment of known antibiotics resistant genes.

The use of case study data in TAPAS
The main outcomes of the case study research in Hungary will be fed directly in the following work packages and tasks:

  • The collected data will be used in WP3.

The state of the case study research in June 2017
The first sampling campaign has been started in May 2017, on progress and will finish in September 2017. The sediment and fish samples are stored at -20°C until the lab work.
