Abstract
Electroshock had been widely used for scientific studies on riverine fish. The present study
was carried out on the bacteriological and psychochemical quality of climbing perch (Anabas testudineus)
that subjected to different voltages of electroshock (50, 70, 90 and 110 V) with controls left untreated.
Electric charge at 70-90 V gives significant benefits to reduce (p<0.05) the bacteria accumulation in A.
testudineus flesh. However, the total bacteria count were not significantly effects after treated at 50 and
110 V compared to the untreated fish. Electroshock were not significantly (p>0.05) giving an excessive
accumulation on lactic acid that might alter the pH value in all samples. Furthermore, treatment at 90-
110 V showed a significantly (p<0.05) lower amount of total colour compared to the untreated samples
and give a pale looks and discoloration to the fish flesh. The suitable electric charge for fish sampling
were suggested at 70-90 V, which significantly contributes to reduce microbial effects and minimal
attributes changes.
