Abstract
The present study provides nutritional characteristics of body composition based on the different collected locations and body sizes in wild eels, Anguilla japonica. Eels were collected in Kyungho river, near the Sachun bay (Gyeongnam) and Inchun river, near Gochang, Jeonnam. Eels were divided by size into the following groups: less than 100 g (Gochang: 75.8$\pm$17.6 g, Sachun: 89.3$\pm$6.42 g) and more than 200 g group (Gochang: 215$\pm$8.95 g, Sachun: 236$\pm$11.7 g). The moisture content of individuals in Gochang area (Gw) was higher than that in Sacheon area (Sw). In the results of proximate analysis, the ranges of moisture, crude protein, crude fat, and crude ash were 63∼72, 16∼20, 6.1∼15.4 and 2.2∼2.8%, respectively. Moisture and crude fat were significantly different (P<0.05) based on the captured locations. In fatty acid composition, the ranges of saturates, monoenes, polyenes, and n-3 PUFA content were 38.0∼48.0, 51.5∼58.5, 1.95∼4.12 and 0.68∼1.53%, respectively. It was significantly different (P<0.05) based on the captured locations. In the amino acid composition, the ranges of essential and non-essential amino acids were 7.11∼12.5 and 8.34∼ 12.9%, respectively. These values were not significantly different (P>0.05) based on the captured locations, however these were significant different (P<0.05) based on their body weight. Therefore, these results indicated that the different body composition depends on the different captured locations and body sizes. Furthermore, it is necessary to examine more varied locations and body sizes for their body composition in eels.
