| Abstract | ||
| The present study include feeding common carp Cyprinus carpio fry by using cysts and Artemia franciscana and Artemia parthenogenetica. The Iraqian Artemia had been growned in side the unit of produetion of natural food/ fish laboratory for gradute studies/ College of Agriculture/ University of Baghdad using aquarium of different volumes, and use cow manure at concentration of 4g/ liter of salty water (85 ppt, sawah lake water). The Artemia fed artifical deit (15.10% protein) also cysts of poor hatching and cheap cost Artemia franciscana were used after decapsulated by using 75 ml solution (AL wazer) and 3 ml of NaOH with continuous ventilation for 1h. Enriched emulsion of Ѡ-3 were produced in laboratory which consist of (200 ml distil water + 75 gm animal gelatin +1 gm egg yolk +2.5 gm vitamins and minerals +0.2gm β-carotene + 40mL cod liver oli). And 0.5mL/litter of salty water from enriched emulsion Ѡ-3 were add to grow nauplii in laboratory after decapsulated cysts by treating with salt solution (35 pp, 10C°, pH8, continuous airation for 4h). Experiment was conducted to feed common carp (0.12-0.18 gm) for 60 days and divided to five different treatments which was fed as follow: Artemia nauplii (T1). Artemia nauplii enriched emulsion Ѡ-3 (T2). Artemia decapsulated cysts (T3). Artemia decapsulated cysts enriched emulsion Ѡ-3 (T4). The statistical analysis of result that T2 followed by T4 had the highest (Growth rate, Waight gain) and T3, T1 had the lowest result for the Growth rate, Weight gain, this study recommend using emulsion Ѡ-3 enriched solution to fed common carp fry | ||
