Comparison Study on the Physicochemical Properties and Sensory Quality of Wild-Caught and Earth Pond-Raised Catfish (Clarias Gariepinus) in Johor, Selangor, and Pahang

| الملخص: | Catfish was highly in demand among Malaysians, however farm-raised catfish is
preferable than wild-caught catfish due to less metallic taste. Generally, the properties
of catfish are influenced by their nutrient intake and habitat condition. In this study, one
sample from wild-caught environment was obtained from Sungai Skudai (Johor Bahru)
while three samples representing of earthen pond farm-raised were obtained from
different locations with Sample A from Lanchang, (Pahang), Sample B from Simpang
Renggam (Johor), and Sample C from Sungai Buloh, (Selangor). These samples were
analyzed for chemical composition and Qualitative Descriptive Analysis (QDA). The
results of moisture, protein, ash, and fat contents of farm-raised samples of catfish was
significantly (<0.05) higher than wild-caught catfish. In fatty acid composition, 25 fatty
acids were detected. Sample B and C of farm-raised catfish showed higher content of
oleic acid (29.26%) and (29.29%) while linoleic acid (22.56%) and (31.85%) than wildcaught
catfish (20.84%) and (13.44%) respectively. Wild-caught catfish were found to
have sensory quality scores for ‘grassy’ odour and firmness higher than farm-raised
catfish. However, farm-raised catfish have darker colour on top of fillet surface which
is Sample A (11.9), and Sample B (11.6) were slightly higher than wild-caught catfish
(11.5). The ‘black thread’ appearance in sample pond A catfish was the most obviously
appeared. Concerning taste attribute, wild-caught catfish showed the highest scores of
charred (3.9) and metallic taste (4.7) than farm-raised catfish. In conclusion, the farmraised
catfish were rich in important nutrients and better taste due to the rear condition
of farm-raised catfish was lower in water pollution also get controlled food intake than
wild-caught catfish live in natural habitat. |
