Item Effects of electroshock on climbing perch (Anabas testudineus) microbiological and physicochemical quality(AACL Bioflux, 2016) Nurul U. Karim; Rohisyamuddin Othman; Abol M. A. Bolong; Marina HassanElectroshock 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.Item Parasites of native and exotic freshwater fishes in the south-west of Western Australia(Murdoch University, 2008) Marina HassanFewer than 200 fish species are found in freshwater habitats in Australia, of which 144 are confined exclusively to freshwater. At least 22 species of exotic freshwater fish have been introduced into Australia, and 19 of these have established self-sustaining populations.
