Abstract :

Introduction: Considering the abundant profit of business of ornamental fishes, research has doneabout their Culture and Preservation this Study done for Survey of Suitable position of growth,Survival and introduction of Proper diet and temperature for Culture of Angel fish fry (PterophyllumScalar).Material and method: In this study, Food treatments include dry blood worm, Artemia decapsulatedcyst and dry blood worm in addition to, Artemia decapsulated cyst.Three temperature at 27, 29 and 31 degree of centigrade were considered with nine repetition andThus 27 aquariums with 60 × 40 × 30 centimeter dimension were allocated for these treatment and atreatment with pollaki food and 28 degree of centigrade was used for the observing group. Thendegree of growth and survival of Angel fry was studied in 30 days.Results: The maximum Variation of length and weigh the treatment with and decopsulatedartemia cysts in oddition to, dry blood worm and the least one was the treatment with andArtemia decopsulated Cysts. The Maximum mean of Survival Percentage Belongs totemperature treatment and decapsulated Artemia Cyst in addition to dry blood warm resulting in81/212 0/877 and the minimum belogs to observant treatment which is 38/182 0 .
