| The current study was aimed to convert organic waste resulting from the houses and restaurants after treatment in addition to Poultry and ruminant slaughter wastes and converting these wastes into fish feed as an alternatives local feed, as well as to reduce the environmental pollution problems caused by such wastes. The experiment of Carp Fish feeding carried out in earthen pounds in middle East Company. This experiment was repeated in the second year, but using a floating cages on the Euphrates River,for carp rearing also by using the same previous treatments.The results of chemical analysis of the raw materials of the feed which were collected from Baghdad in a period from 01/11/2013 up to 01/03/2014 showed that the rate of protein was reached to 24.52 and 21% for fats , 7.84 and 12.21% for each of the restaurants , Poultry wastes and Ruminants wastes respectively. The concentration of mycotoxins were 12.5, zero and 5.9 ppb in the restaurants wastes and 6.6, zero and 31.5 ppb in the Poultry slaughter house and 9.4, zero and 14.6 ppb in the wastes of the slaughterhouse for each of the aflatoxin, ochratoxin and trichothecin respectively. The observed results of toxins were generally within the permissible limits in the feed of fish.Results of rearing and nutrition of fish in the ponds showed that the fish treated with alternative feed (1) were exceeded over the comparison feed in all studied parameters (final weight, weight gain, relative growth and food conversion ratio), while the results did not find significant differences between growth results of different feed in the experiment of floating breeding cages. The results also did not showed any effect of feed to the concentration of lead and cadmium in the tissues of the fish muscles | ||
