The study was conducted in Vinh Chau commune, Chau Doc city to apply Aspergillus oryzace yeast when incubated to raise commercial perch (Anabas testudineus) intensively in land ponds. Monitor and evaluate technical parameters such as: weight gain, survival rate, FCR of experimental ponds with traditional ponds after the end of the farming harvet season; Evaluate the economic efficiency of using Aspergillus oryzace yeast when fermentation to raise commercial perch intensively compared to the traditional perch farming model that does not use Aspergillus oryzace when fermemtation. These experimental results indicated that fish growth indicators improved in ponds supplemented with probiotics and achieved the best results based on average daily growth in NT2 at 3.01%; NT1 is 2.90%;. The FCR coefficient fluctuated between treatments from 1.8 to 1.6. The survival rate of fish over 3 months of culture/crop in treatments without probiotic supplement was 93.34% and with probiotic supplement 2 was 94.7%. Productivity and profit of apply Aspergillus oryzace yeast were higher than those without apply.
