บทคัดย่อ

The experiment was done to evaluate the efficiency of mixed microorganisms, EM, which is being used widely for agriculture and aquaculture in Thailand, in semi-closed recirculated culture system of hybrid catfish, in concrete ponds. Results of the experiment showed non-significant difference (P>0.05) of the average values and trends of key water quality parameters (pH, dissolved oxygen, carbondioxide, BOD5, ammonia, nitrite, nitrate, soluble orthophosphate, sulfide, total suspended solid, and chlorophyll a). The use of EM also had no effect no survival rate, growth rate and total production of hybrid catfish.
