“…However, valuable PUFAs might not only occur in the predominantly eaten components of the seafood organisms, but could also be present in the undervalued presumptive waste tissues of fish and shellfish. For example, in fish, lipids are not only stored in the subcutaneous tissue, belly flap, and muscle, but are also high in mesenteric tissue, head, and liver [29]. A number of previous studies have investigated the quality of fatty acids in seafood waste tissues.…”

Correlation between Fatty Acid Profile and Anti-Inflammatory Activity in Common Australian Seafood by-Products

Marine organisms are a rich source of biologically active lipids with anti-inflammatory activities. These lipids may be enriched in visceral organs that are waste products from common seafood. Gas chromatography-mass spectrometry and fatty acid methyl ester (FAME) analyses were performed to compare the fatty acid compositions of lipid extracts from some common seafood organisms, including octopus (Octopus tetricus), squid (Sepioteuthis australis), Australian sardine (Sardinops sagax), salmon (Salmo salar) and school prawns (Penaeus plebejus). The lipid extracts were tested for anti-inflammatory activity by assessing their inhibition of nitric oxide (NO) and tumor necrosis factor alpha (TNFα) production in lipopolysaccharide (LPS)-stimulated RAW 264.7 mouse cells. The lipid extract from both the flesh and waste tissue all contained high amounts of polyunsaturated fatty acids (PUFAs) and significantly inhibited NO and TNFα production. Lipid extracts from the cephalopod mollusks S. australis and O. tetricus demonstrated the highest total PUFA content, the highest level of omega 3 (ω-3) PUFAs, and the highest anti-inflammatory activity. However, multivariate analysis indicates the complex mixture of saturated, monounsaturated, and polyunsaturated fatty acids may all influence the anti-inflammatory activity of marine lipid extracts. This study confirms that discarded parts of commonly consumed seafood species provide promising sources for the development of new potential anti-inflammatory nutraceuticals.

“…Because it is absorbed more efficiently and enters the bloodstream more quickly, it is considered to be the best source of collagen for pharmaceutical applications. Moreover, 75% of the total weight of fish is discarded as wastes in the form of skins, bones, fins, heads, guts, scales and bladder during processing [11]. If we can reutilize fish processing wastes for the production of collagen-like biomaterials, it may increase the economic value of the fish and fish processing industry.…”

A novel enzymatic method for extraction and preparation of fish collagen from swim bladder revealed the occurrence of α, β and γ bands with approximately 12.1 g/100g collagen corresponding to 89% of collagen and thus confirmed the nativity and purity of the fish collagen. FT-IR studies confirmed the retention of all three amide bands of I, II and III, and triple helixcity. UN-crosslinked and UV-crosslinked fish collagen membrane records a very high temperature of helix denaturation at 197˚C and 215˚C, shrinkage temperature at 50˚C ± 3.2˚C and 62˚C ± 2.7˚C and tensile strength at 16.89 ± 2.5 and 120.02 ± 1.0 Kg/cm 2 respectively. Fish collagen matrix promoted NIH 3T3 and L6 cellular growth and proliferation. The study indicates that availability of pure fish collagen could replace bovine collagen in tissue engineering applications.

“…Coronary heart diseases have been identified as a leading cause of death in various parts of the world including Pakistan, with mortality rates increasing yearly. In recent years, fish lipids have also assumed a great nutritional significance owing to their protective role against the development of cardiovascular diseases and rheumatoid arthritis (Ackman, 1967;Burr et al, 1989;Polvi and Ackman, 1992;Shahidi and Boota, 1994). Fish lipids are rich in polyunsaturated fatty acids (PUFA) that are essential for fish growth and health.…”

SUMMARY:Fish from the river Chenab were analyzed for DNA damage by the Comet and Micronucleus assays. The fatty acid profile was determined by gas chromatography using a Flame Ionization Detector. Atomic absorption spectrophotometry showed significant (p<0.05) levels of contamination due to Cd, Hg, Cu, Mn, Zn, Pb, Cr, Sn and phenols in the fish habitat. The Comet assay revealed significant (p<0.05) DNA damage in Cirrhinus mrigala of 37.29±2.51%, 34.96±2.53% and 38.80±2.42% in the comet tail, in the tail moment of 23. 48±3.90, 19.78±4.26 and 14.30±1.82, in the olive moment of 16.22±2.04, 13.83±1.96 10.99±0.90, respectively, from three experimental sites. The micronucleus assay showed a high frequency of single micronucleus induction of 44.80±3.73, double induction of 06.20±0.97 and nuclear abnormalities of 09.60±1.72, as calculated in a thousand cells. C8:0, C12:0, C20:0, C16:1(n-7), C16:1(n-9), C20:1(n-9), C18:2(n-6), C18:4(n-3), C20:5(n-3), C22:4(n-6) fatty acids were found missing in the fish with a higher intensity of DNA damage but were found in optimal amounts both in farmed and wild fish from non polluted habitats. A highly significant (p<0.01) correlation was also found in saturated, unsaturated fatty acids and DNA damage and habitat. The present study revealed that the habitat of even lower intensity pollutions not only induce DNA damage but also confiscate essential fatty acids of the omega series and reduce the amount of unsaturated fatty acids for which fish is preferred over other animals.KEYWORDS: Cirrhinus; DNA damage; Fatty acids; Habitat; Niche; Pollution RESUMEN: Efectos inducidos por el hábitat sobre mutaciones y perfil de ácidos grasos en carpas mrigala que habitan en el fondo del río Chenab. Los daños en el ADN de los peces del río Chenab se analizaron mediante la técnica del "ensayo del cometa" y el ensayo de micronúcleos. El perfil de ácidos grasos se determinó mediante cromatografía de gases con detector de ionización de llama. La espectrofotometría de absorción atómica mostró diferencias significativas (p<0.05) de los niveles de contaminación por Cd, Hg, Cu, Mn, Zn, Pb, Cr, Sn y fenoles en el hábitat de los peces. El ensayo del cometa mostró daños significativos (p<0,05) en el ADN de las carpas mrigala de tres sitios experimentales: 37,29±2,51%, 34,96±2,53 y 38,80±2,42% del ADN en la cola del cometa, momento de la cola con 23,48±3,90, 19,78±4,26 y 14,30±1,82% y cola media con 16,22±2,04, 13,83±1,96 10,99±0,90. Los ensayos de micronúcleos mostraron una alta frecuencia de inducción de micronú-cleos como única 44,80±3,73, 06,20±0,97 y doble anomalías nucleares 09,60±1,72 calculados en miles de células. C8:0, C12:0, C20:0, C16:1(n-7), C16:1 (n-9), C20:1(n-9), C18:2(n-6), C18:4(n-3), C20:5(n-3) y C22:4(n-6) se mostraron como ácidos grasos que faltan en el pescado que tiene una mayor intensidad de daño en el ADN, aunque se encuentran en cantidades óptimas, tanto en los peces de piscifactoría como en los salvajes donde no hay hábitats contaminados. Se encontró una correlación altamente significa...
