The experiment was conducted at the Fish Culture Research Unit at the Experimental Station of EPAGRI -Caçador - SC (Brasil), beginning on February 10 and ending on June 9, 2009, in 09 asbestoscement tanks with a capacity of 1,000 liters of water, supplied individually with water supply from the dam at a flow rate of 0.5 liters per minute. The experimental design was completely randomized in a factorial 3 × 3 were evaluated in the introduction of Chlorella minutissima the amount of 1 liter per day (1.4 × 107 cells / ml), commercial feed in the amount of 5% of the total weight fish and pig manure also in the amount of 5% of the total weight of fish in three replicates with 20 common carp (Cyprinus carpio L.) of Hungarian variety in each plot. The average initial weight of fish was 1.11 ± 0.02 g and initial length of 6.21 ± 0.71 cm. The final average weight of the treatment demonstrates the unique quality of the commercial diet compared to treatment with pig manure and Chlorella minutissima. Since the average weight of 6.03 ± 0.49 and 4.69 ± 0.98 grams, through statistical analysis has no significant difference between the pig manure and Chlorella minutissima which also occurs in weight gain (4, 92 ± 0.49 and 3.58 ± 0.98 grams). We conclude that the use of Chlorella minutissima in the growing is a viable alternative for creating common carp fingerlings (Cyprinus carpio L.
