Abstract

This study conducted to find the effect of partial replacement of soybean meal by Spirulina Arthospira platensis on some blood picture and biochemical criteria in common carp Cyprinus carpio. Fish were fed on five experimental diets contained spirulina with ratio 1.45%, 2.90%, 3.54% and 6.10% of the total diet as well as control ( without spirulina) for 56 days . Results of the statistical analysis showed a significant decrease (p≤ 0.05) in the concentration of hemoglobin in treated fish fed on spirulina diets, meanwhile a significantly differences (p≤0.05) for stress index and the albumin criteria for fish fed at fifth diet comparing with control diet. The aspartate amino transferase for fish fed on the control diet increased significantly (p≤ 0.05) compared for other experimental diets. The results of the current study show that replacing the soybean meal with spirulina by 11.8 % (3.54 of the total diet) improved the studied criteria compared to the control diet.

Highlights

Aquaculture contributes to meet the increasing needs of the population of the aquatic organism, including fish (4), because the commercial fishing from open water suffers from a decrease in its contribution to filling this deficit to 50% of the consumer needs of seafood in all parts of the world (16)
Per capita consumption of fish in Iraq was 4 kg per year, while the average Arab per capita consumption of aquatic organisms had been estimated at 10.97 kg / year compared to 19.9 kg /capita worldwide (6). It known that the soybean meal is low in its sulfur amino acid contents as well as, the presence of a number of inhibitors nutrition, including gossypol; trypsin inhibitor; hemagglutinating agents; glucosinolate; phytic acid and erucic acid that reduced the utilization of soybean meal by fish (17)
The present study aimed to find the effect of partial substitution of soybean meal by blue-green algae on blood picture and efficiency of ALT, AST enzyme and creatine

Summary

Introduction

Aquaculture contributes to meet the increasing needs of the population of the aquatic organism, including fish (4), because the commercial fishing from open water suffers from a decrease in its contribution to filling this deficit to 50% of the consumer needs of seafood in all parts of the world (16). Results of the statistical analysis of PCV cells 0.05) was observed for fish fed to the second showed that there were no significant and control diets compared with other differences among fish fed on different experimental diets (Table 3) which reached experimental diets, which ranged between 20 75.2 and 78.1, respectively.
