A Study on Gilthead Seabream (Sparus aurata) Fish Feed Replacement of Fishmeal at Different Rates Use of Canola Meal (Brassica spp.) on Growth Rate, Feed Utilisation and DigestibilityKeywords: Bal?k unu,?ipura,kanola unu,sindirilebilirlik,büyüme performans?,yemden yararlanma Abstract: This study was conducted to identify optimum exchange ratio of canola meal in fish feeds instead of fishmeal, using %45 protein and %18 fat commercial control feeds and %10, %15, %20, %25 and %30 canola meal (KA) based feeds for sea breams with a starting weight of 49,86±0,009 gr by analyzing growth performance, food conversion ratio and digestibility. After 98 days of experiment, specific growth rate and relative weight gain although was statistically significantly different during 14-28 days (p<0,05), it was insignificant at the end of the trial. Food conversion ratio (FCR) was lowest for KA30 (4,54±0,1), and highest for KA10 (5,31±0,2) group, protein efficiency was highest in KA30 and lowest in KA10 group, productive protein value was highest in KA30 with 0,318±0,02 (p<0,05). Digestibility performance for crude protein and dry matter was the highest in the control group and lowest for KA10 group and for fats lowest was KA10 where highest was (p<0,05) KA30 with similar results compared to KA0 and KA15
