Abstract

This study aimed to evaluate the effects of Chlorella and germinated barley powder on the hematological and biochemical parameters of (Cyprinus carpio L.). An experiment was designed with five treatments; Groups included T1: Diet without any supplement (Control), T2: adding 5 % Chlorella/ kg diet, T3: adding 10 % Chlorella / kg diet, T4: adding 10 % germinated barely / kg diet, T5: adding 20 % germinated barely/ kg diet. At the end of the experiment, the hematological and Immunological parameters were measured. The results revealed that supplementation of Chlorella and germinated barley in diets in which T4 were higher significantly in each of hemoglobin and red blood corpuscles. T1 was significantly higher in the control. A different significance observed in each of Mean Corpuscular Hemoglobin Concentration (MCHC), Mean Corpuscular Volume (MCV), and Mean Corpuscular Hemoglobin (MCH). Significant variants observed in differential WBC count in T2 and T4 and Monocytes %, a significant difference seen among the treatments in each of Lymphocytes % and Granulocytes %. Significant differences occurred by adding the Chlorella and germinated barely in each Total protein, Alanine aminotransferase activity (ALT), Aspartate aminotransferase activity (AST), Albumin and Globulin among treatments. A significant difference observed in the Hepatosomatic index and Gillsomatic index, T5 with 20 % germinated barely was differ significantly in each of Spleensomatic and Kidneysomatic Index. Based on the results, supplementation of Chlorella and germinated barley in diet can play a role in effecting on some blood and biochemical parameters.

Highlights

The importance of aquaculture has escalated in the past years via people's diet improvement, creating work opportunities in rural areas and changes the import through conservation of foreign exchange [1]

Summary

Introduction

The importance of aquaculture has escalated in the past years via people's diet improvement, creating work opportunities in rural areas and changes the import through conservation of foreign exchange [1]. Anderson et al [2] stated that this growth has often increased the way of seafood generation, operated and consumed. In food industries, it has redefined the role of seafood as well. As microalgae have greater photosynthetic efficacies, greater harvests and growth rates, and required for few space of land for cultivation and have the capability to grow in salty waters and arid and barren land areas, they might demonstrate as an alternative to terrestrial crops [3]. Since 1961, the average annual increase in global apparent food fish consumption (3.2 percent) has outpaced population growth (1.6 percent) and exceeded that of consumption of meat from all terrestrial animals, combined (2.8 percent) and individually (bovine, ovine, pig, other), except poultry (4.9 percent). Food fish consumption has grown from 9.0 kg in 1961 to 20.2 kg in
