BREEDING POND OF CARP AND ITS EFFECT ON MICOLOGICAL STATUS OF WATER

The aim of the study was to assess the impact of carp pond culture on mycological condition of surface waters. The study was conducted in a fish farm in Ślesin. To indicate the number of fungi the water was sampled at the tributary, ponds production and winter habitats and at the outflow. This study has shown that ponds may slightly reduce the number of fungi, as well as improve some physicochemical parameters of water.

Dynamics of quantitative variation for Escherichia coli in meat industry wastewaters

Wastewaters from the meat industry are a potential source of epidemic risk, owing to considerable amounts of chyme (the content of stomachs and intestines) and blood from beef animals. These wastes get into wastewater and further into the environment, causing a sanitary-epidemic threat. Pathogenic viruses, fungi, bacteria and parasites, which can be found in wastewaters from the meat industry, are an epidemic hazard for people and animals. Therefore, effective methods of their utilization have been sought for many years. The methods used so far are too energy-consuming and material intensive (GERBA & BITTON 1984).
