The present study attempts to identify some of the differences between skull bones two species Cyprinus carpio and Carassius carassius, which belong Cyprinidae family. is a taxonomic diagnostic are considered local fish abundant in Iraqi aquatic environment

The objectives of the present study were designed to evaluate the probiotic potential of selected probiotic strains on the growth and gut microflora of Carassius auratus. Standard methods were followed for analyzing Physico-chemical parameters of experimental water. Four different probionts, such as Lactobacillus acidophilus, Lactobacillus plantarum, Lactobacillus sporogenes were incorporated w...

The aim of this study was to investigate the genetic mechanism of the transparent trait in transparent crucian carp. We observed body color development in transparent crucian carp larvae and analyzed heredity of color in hybrids produced with red crucian carp, ornamental carp, and red purse carp. The results showed that the body color of the newly hatched larvae matured into the adult pattern a...

Within the genus Carassius Jarocki, 1822 , crucian carp ( C. carassius L., 1758) occurs naturally in northern part of Middle Danube Basin (Austria, Morava, Slovakia). This species has least concern status this region, but observations last decades suggest that it is very close to extinction here. The distribution limited a small number vanishing lentic habitats (oxbow lakes, marshlands). These ...

Five crucian carp, Carassius auratus langsdorfiicarps had been reared in a closed water recirculating system. The system was equipped with the compact bioreactor using the plate gels capable of both nitrification and denitrification in a single unit. Ammonia and nitrite concentrations in the rearing water had been maintained below 0.05 mg-N/L, and nitrate concentration also controlled between 2...
