Abstract
A trial was carried out to sustain the most suitable conditions for using Chlorella vulgaris cells in feeding silver carp fish. Chlorella vulgaris cells were found to be rich in amino acids content Leucine, isoleucine, lysine, threonine, treptophan, phenylalanine + tyrosine and valine contents were higher than those of the FAO pattern of fish diet The sulphur containing amino acids (methionine + cystine) were lower. Fish yield , specific growth rate and protein content reached their maximum level at 20% of dried algal biomass supplemented to artificial fish, but further supplementations were of negative effect. The study of the biochemical composition of fish reared on the different variance of artificial feed (AF) with different dry algal cells supplements showed an increase of protein content of fish up to 20% supplementation, which decreased again on further substitution of AF. The level of ammonia content in water fish tank showed certain success when fish fed contain 20% of dried algal biomass supplemented artificial fish food compared with other treatments. Their content of water ammonia fish tanks increased with the increase of nitrogen content of the tested diet variance.
