We evaluated seasonal variations in the proximate, fatty acid and total amino acid compositions and mineral content of the muscles of wild and cultured Korean bullhead Pseudobagrus fulvidraco. The wild and cultured samples showed a significantly higher proportion of crude lipids than other components. Crude lipid content was highest in May in wild fish but lowest in May in cultured fish. We found no significant difference between wild and cultured samples in terms of fatty acid and total amino acid compositions and mineral content. The levels of saturated fatty acids (SFA) and polyunsaturated fatty acids (PUFA) as well as n-6/n-3, were higher in the muscles of wild fish compared with those of cultured fish. However, monounsaturated fatty acids (MUFA) levels were higher in cultured fish. Both wild and cultured fish were good sources of eicosapentaenoic acid (EPA) and docosa hexaenoic acid (DHA). In wild fish, the Mg and Zn contents were highest in August, while the Ca, P, Na, K, Fe, and Cu contents were highest in May. However, the mineral content of the cultured fish did not exhibit significant seasonal variation.

Many studies have been conducted on the methods of collagen extraction from fish skin. However, the specific composition of the collagen has not been reported so far. This study aimed to identify components other than amino acids in collagen. Collagen was extracted from the skin of tilapia (Oreochroma niloticus), flounder (Paralichthys olivaceus), and red sea bream (Pagrus major) using a commonly used acid extraction method. Thereafter, the component composition of collagen was confirmed. The yield of collagen was 1.11% from tilapia, 1.79% from red sea bream, and 2.06% from flounder. The protein content of all three samples, tilapia (85.39%), red sea bream (87.48%), and flounder (92.06%) collagen was over 85%. Analysis of the amino acid composition revealed that, glycine accounted for the highest proportion in all the samples of fish skin and collagen. The imino acid content was highest in the tilapia skin (151.1 residues) and collagen (210.7 residues). The triglyceride content in the of collagen was less than 0.7% in tilapia (0.37%), sea bream (0.61%), and flounder (0.31%). The major fatty acids in collagen were palmitic acid, stearic acid, and nervonic acid. Calcium in the fish skin accounted for the highest proportion of the mineral composition at 23.96∼466.84 mg/100 g, and the collagen contained a large amount of sodium 189.28∼1,433.52 mg/100 g. The collagen contained galactose, glucose, and mannose, and the galactose and glucose levels were three times higher than those of fish skin. Our study confirmed that the collagen extracted from fish skin contained lipids and minerals even though it was purified.

The proximate compositions and fatty acid profiles of Antarctic toothfish Dissostichus mawsoni that was caught in the southern Ross Sea (J, L) of the Antarctic Ocean were studied. The lipid contents of samples from J and L were 18.2 and 21.1%, respectively. The protein and ash contents were similar for samples J and L. The prominent fatty acids in the total lipids of the fish muscle were 18:1n-9, 16:1n-7, 16:0, 14:0, 18:1n-7, 20:5n-3 (eicosapentaenoic acid, EPA), and 22:6n-3 (docosahexaenoic acid, DHA). In addition, the total fatty acids of bycatch products in the toothfish stomachs (Pleuragramma antarcticum, Gerlachea australis, Pasiphaea sp., Trematomus eulepidotus, Chionodraco hamatus, Chionodraco myersi, and Neopagetopsis ionah) were determined. The prominent fatty acids in those species were 18:1n-9, 16:0, 14:0, DHA, EPA, and 18:1n-7.
