Title

EFFECTS OF ADDING CERATOPHYLLUM DEMERSUM TO RATION ON GROWTH RATE OF RAINBOW TROUT (ONCHORHYNCHUS MYKISS)

Pages

  103-112

Abstract

 In accordance to evaluation of usage of CERATOPHYLLUM DEMERSUM on rate of growing as well as SURVIVAL rate of RAINBOW TROUT, four different diets were prepared that consist of 0%, 2%, 4% and 6% of the mentioned plant. This experience was tested with a three time repetition in a complete random model. The total number of all tested fish was 96 with the initial weight and length of 11.12±0.71 grams and 91.7±3.05 millimeters respectively. They were introduced to twelve aquariums considered the place of testing. In five weeks that the test occurred, some of the growing scales like Specific GROWTH Rate (SGR), Daily GROWTH Rate (DGR), Condition Factor (CF), Food Conversion Ratio (FCR) and SURVIVAL Rate (SR) for all diets were calculated. Results of data variance analysis presented that different diets did not show any significant differences in SURVIVAL Rate (SR) and Condition Factor (CF), however, meaningful differences in Weight (W), Specific GROWTH Rate (SGR), Daily GROWTH Rate (DGR) and Food Conversion Ratio (FCR) was observed (P<0.01) and also, after the test, the length of juveniles was proved to be dissimilar based on the diets (P<0.05). Based on the results, the diet No.3 consisting of 4% CERATOPHYLLUM DEMERSUM had the greatest effect on juveniles growing. Moreover, results of the Duncan’s comparative mean test demonstrated the maximum of 11 millimeter increase in length and 2.47 gram in weight with the growing scale amounts of 0.15, 1.36 and 0.74 for DGR, SGR and FCR respectively.
