Larger size climbing perch is much preferred by consumers due to its size as it is more tedious to process small sized climbing perch. Despite of the high demand on this fish, comparative study on nutritional composition such as mineral and fatty acids content in different sizes of climbing perch are still deficient due to lack of scientific research on this species in Malaysia. Hence, this study was done to determine and compare proximate, mineral and fatty acids composition in large and small sizes of climbing perch. Subsequently, the data was used to determine the correlation between fish size - proximate composition, fish size - mineral composition and fish size - fatty acid composition. Fish were randomly sampled from fish market in Terengganu, Selangor and Perak. Fish samples were killed according to hypothermia method before categorized into two groups: large and small climbing perch based on average body weight and total body length. Average body weight and total body length of large climbing perch were 73.18 ± 1.04 g and 15.93 ± 0.08 cm while average body weight and total body length of small climbing perch were 27.13 ± 0.83 g and 11.72 ± 0.14 cm respectively. Proximate, mineral and fatty acid analysis were carried out using Association of Official Analytical Chemists (AOAC) method, Inductively Coupled Plasma-Optical Emission Spectrometry (ICP OES) and Gas Chromatography-Mass Spectrometry (GCMS), respectively. Results from the analyses were compared and analyzed using two-way ANOVA, while Pearson’s correlation test was used to check the relationships between fish size - proximate composition, fish size - mineral concentrations and fish size - fatty acid content. The study found that small climbing perch showed higher protein and ash (45.00% and 30.35%) while large climbing perch showed higher lipid content (17.19%). On the other hand, concentrations of minerals (mg/kg) were higher in small climbing perch, yet, mineral content per tail of large-sized Anabas testudineus was higher than small-sized Anabas testudineus. Nevertheless, large and small climbing perch had similar fatty acids content. Based on Pearson’s correlation analysis, there was significant negative correlation between ash content and fish size. All analysed minerals were negatively correlated to fish size, while none of fatty acid groups were significantly correlated with fish size. In conclusion, proximate, mineral and fatty acids composition in both fish categories were determined and compared. The correlation between fish size – chemical composition was also determined. Both fish sizes are found suitable for use to fulfil the nutritional expectations of consumers. 2020_Nutritional Composition of Different Size Climbing Perch, Anabas testudineus (Bloch, 1792) Anabas testudineus Dissertations, Academic Sila masukkan subject wajib Dissertations, Academic untuk semua tesis..

| summary | Climbing perch (Anabas testudineus) is commonly eaten by Malaysians due to its tender flesh, tasty flavor and its benefit to human health. Larger size climbing perch is much preferred by consumers due to its size as it is more tedious to process small sized climbing perch. Despite of the high demand on this fish, comparative study on nutritional composition such as mineral and fatty acids content in different sizes of climbing perch are still deficient due to lack of scientific research on this species in Malaysia. Hence, this study was done to determine and compare proximate, mineral and fatty acids composition in large and small sizes of climbing perch. Subsequently, the data was used to determine the correlation between fish size - proximate composition, fish size - mineral composition and fish size - fatty acid composition. Fish were randomly sampled from fish market in Terengganu, Selangor and Perak.
