The aim of this study was to investigate the effect of using spirulina algae and Natuzyme Multi-Enzyme in the diet of common carp on growth performance, survival and hematological parameter for 60 days. For this, 540 pieces of common carp fry with an average weight of 102±0.2 g were prepared and under 8 treatments including: 1% spirulina algae powder, 2% spirulina algae powder, 0.05% Natuzyme Multi-Enzyme, 0.1% Natuzyme Multi-Enzyme, combination of spirulina powder (1 and 2%) and Natuzyme Multi-Enzyme (0.05%), combination of spirulina powder (1 and 2%) and Natuzyme Multi-Enzyme (0.1%) and control group (each with 3 replicates) were fed daily 3% of body weight. At the end of the experiment, bioassays were performed on all fish to examine growth indices. In order to perform hematological examinations, blood sampling of all treatments were completely randomly performed. The results of this study showed that the treatments fed a diet containing a combination of 2% algae powder and 0.1% Natuzyme Multi-Enzyme had a higher rate of weight gain, specific growth rate and feed conversion ratio compared to other experimental treatments (P<0.05). However, the survival percentage was not significantly different between the treatments and the control group (P <0.05). Also, the results showed that there was no significant difference in hematological parameters between treatments fed wih spirulina powder and Natuzyme Multi-Enzyme single and in combination from the control group (P >0.05). In addition, the number of white blood cells, red blood cells, hemoglobin and hematocrit in all treatments were not statistically different from each other (P >0.05). In general, due to the positive effects of combining spirulina algae powder at 2% of the diet and Natuzyme Multi-Enzyme at 0.1% of the diet, adding them is recommended to the diet of common carp.

Spirulina is a cyanobacterial photosynthesis that is grown commercially in many tropical and subtropical countries and temperate regions for human and animal nutrition. This commercial product is used as a rich source of protein and vitamins in the pharmaceutical, food and chemical industries due to its valuable nutrients. In the last two decades, the production of microalgae for food has increased more than five times and now algae are consumed in about 80 countries. Also they are produced in 22 countries, where the European market consumes lonely 32% of total production. Based on the observations made, one of the highest growth rates the fastest growing market, with an annual growth rate of 15%, has been recorded in this area. The algae has been introduced by the US space agency (NASA) as a superfood and tries to provide a healthy diet for astronauts with the help of Spirulina. The aim of this study was to investigate and identify spirulina algae as food for the next generation of humans.

This experiment was conducted to evaluate the effect of Spirulina pletensis powder on the liver and digestive enzymes and biochemical parametese of Mugil cephalus for 60 days. The experiment was conducted in a completely randomized design with 450 of grey mullet larvae (with average weight of 0.72±0.02g) in 5 treatments and 3 replicates (n=30 in each replicate) and included: control group without using algae extract, an another groups (treatment 2, 3,4 and 4) the amounts of this extract were 5,10,15 and 30 g/kg food The results showed that at the end of experiment, although the highest the activity of protease and lipase enzymes, the lowest the activity of alanin aminotransferase (ALT) and alkaline phosphates (ALP) were observed in treatment containing 15g/kg spirulina algae powder, in all of these parameters, treatment 5 (20 g/kg) (4) showed a significant difference compared with control treatment (P<0.05), in ALT, amylase and lipase, there were no significant difference among treatment 4 and 5 (P>0.05). The lowest cholesterol, glucose and triglyceride, the highest globulin, albumon and total protein were recorded in treatment 4. Finally, the present results showed that use of the diet containing 115g/kg spirulina algae had positive effects on the activity of liver and digestive enzymes and blood biochemical parameters of grey mullet.
