Proximate composition and fatty acids profiling of Seahorse originated from Simeulue, Aceh-Indonesia

Abstract

The aim of this study was to determine the proximate composition, quantitative of fatty acids analysis as well as the content in the seahorse sample, Hippocampus sp which originated from Sibigo waters, Simeulue, Aceh, Indonesia. In this study, proximate composition and fatty acids of seahorse were determined. Based on the proximate analyses that had been conducted, results showed that protein was the most abundantly found in the seahorse (39.32±0.22%), orderly followed by carbohydrate (28.48±0.25%), ash (25.43±0.16%), moisture (6.29±0.13%) (dry weight basis) and fat (0.47±0.30%). Fatty acids profiling and analysis were also conducted by using the a GC-MS (Gas Chromatography-Mass Spectroscopy). The analysis result showed that sample possessed of saturated fatty acids in big size were palmitic acid, stearic acid, myristic acid, and lauric acid. While unsaturated fatty acids were arachidonic acid, linoleic acid and oleic acid. Traces of saturated fatty acids in small seahorse were found in the sample including palmitic acid, stearic acid, miristic acid and lauric acid, while unsaturated fatty acids were linoleic acid and oleic acid. The highest saturated fatty acid in seahorse was palmitic acid (60.67%), and unsaturated fatty acids were oleic acid (45.5%), arachidonic acid (25.08%) and linoleic acid (0.93%).

Comprehensive biochemical analysis and nutritional evaluation of fatty acid and amino acid profiles in eight seahorse species (Hippocampus spp.)

“…Additionally, while the investigation into marine amphipods as an alternative feed for Hippocampus erectus examined dietary effects on a single species [ 18 ], our study's broader species range offers foundational data for future studies on diet and nutrition across different seahorse species. Research on the proximate composition and fatty acids of seahorses from Simeulue provided valuable regional data but did not include amino acid profiling [ 16 ]. Our study expands on this by offering both proximate and biochemical analyses, providing a more detailed nutritional assessment.…”

“…(2) Comprehensive Profiling: Previous research often focused on either fatty acids or amino acids but not both. For instance, Abdullah Abbas et al provided data on proximate composition and fatty acids but lacked amino acid profiling [ 16 ]. (3) Reproductive and Gender Differences: Previous studies often did not differentiate between genders or reproductive statuses [ 1 , 17 , 18 ].…”
