Abstract
Benthos is the most important ingredient of natural food of fish in carp ponds. Its chemical composition and profile of fatty acids has not been studied up to now. The aim of this research was to determine these parameters for the benthic organisms that carp feeds on, which are a source of fatty acids and cholesterol, as well as amino acid composition and fatty acid profile of these organisms. Benthos was sampled from 2 ponds with Ekman-Birge sediment sampler in July and October. Benthos from the bottom of drained ponds was also collected after the harvest. The content of basic nutrients was determined in the benthos samples using AOAC procedures. Amino acids and fatty acids profiles were also determined. It has been found that benthos in carp ponds contains a high amount of protein and it is rich in the essential amino acids. The limiting amino acids in benthic protein are the sulphur amino acids: cystine and methionine as well as tyrosine. The fat content of the benthos is at intermediate level with a high content of essential unsaturated fatty acids.
