“…The fatty acid profiles exhibited a dominance of unsaturated fatty acids (UFAs) for all samples exceeding 65% of the total fatty acid content. These findings are in line with those previously reported by Navarro-Garcia et al (2004) and Le Nechet et al (2007). Among the saturated fatty acids (SFAs), those occurring at the highest proportions were palmitic acid (C16:0, ranging from 19.8% to 24.52%) followed by stearic acid (C18:0, ranging from 2.34% to 6.77%) and myristic acid (C14:0, ranging from 0.57% to 1.06%).…”

“…For example, fatty acid distributions in the muscle, liver, and gonads of three ray species (Dasyatis marmorata, Rhinobatos cemiculus, and Rhinoptera marginata) from the east tropical Atlantic Ocean were determined by Ould El Kebir et al (2003). Also, liver lipids of Dasyatis brevis and Gymnura marmorata from the California Gulf (Navarro-Garcia et al, 2004) and Himantura bleekeri from the Indian coast (Le Nechet et al, 2007) were analyzed. These authors had found that the liver lipidic fractions of all ray species studied contained a high amount of PUFAs (up to 30% of the total lipids), mainly composed of DHA and EPA.…”

The proximate composition, fatty acid profiles, physicochemical properties and radical scavenging activities of liver oil from three ray species, Dasyatis pastinaca, Dasyatis violacea and Rhinoptera marginata, were investigated. Lipid contents of D. pastinaca (58.27%) and D. violacea (57.33%) were significantly high compared to those of R. marginata (10.90%). Among minerals, K and Na were the most abundant elements and the highest values were observed for R. marginata (153.7 and 115.86 mg/100 g, respectively). The fatty acid profiles exhibited a dominance of unsaturated fatty acids exceeding 65% of the total fatty acids. C16:0, C18:0 and C14:0 were the major saturated fatty acids. The most abundant monounsaturated fatty acids were C18:1 (10.88-21.98%) and C16:1 (4.47-23.95%). Interestingly, omega-3 polyunsaturated fatty acid profiles exhibited a dominance of eicosapentaenoic acid (3.36-5.51%) and docosahexaenoic acid (9.07-30.50%). D. pastinaca contained the highest carotenoid and total phenolic content accompanied with the strongest free radical scavenging abilities. This study suggests that ray livers which were actually wasted, could be used as new raw material for omega-3 polyunsaturated fatty acid oil production and a good source of carotenoids and phenolic compounds.

“…Accordingly, the highest amount in our study period was noted for PUFA n-3. A high level of cholesterol is required for the biosynthesis of sex and molting hormones (Kanazawa 2001), as well as for the formation of cell membranes and intercellular structures in crustaceans (Le Nechet et al 2007). Cholesterol is also an intermediate in the biosynthesis of ecdysteroids (Hopkins 2009).…”

The composition and the content of lipids, fatty acids and sterols during spawning (spring) in different tissues of herring Clupea harengus membras were compared with quantities of lipid compounds in abdomen muscle of brown shrimp Crangon crangon. The largest quantity of fatty acids in lipids (93.7%), was observed in fish muscle. The liver was characterized by a higher content and variety of sterols (about 4.6 times more than in fish muscle), and in fish sperm, additional fatty acids were identified and the highest amount of EPA and DHA (22% and 34% of fatty acids, respectively) was recorded. The brown shrimp, despite its small size, contained significantly more lipids than the Baltic herring per g of tissues. Fatty acids were at the same level (83% * Corresponding author: piotr. stepnowski@chem.ug.edu.pl of the total lipids in shrimp muscle and 93.7% in fish muscle), but the amount of sterols was significantly higher in the muscle of shrimp (5.50 ±0.31 mg g -1 , 17% of total sterols, n=10) than in fish muscle (1.33 ±0.04 mg g -1 , 6.3% of total lipids, n=6). And thus, shrimp is a good source of food for higher trophic levels, and in consequence -a good source of PUFAs for humans. With these results we prove that shrimp and herring play an important role in the supply of EFAs, which has great pharmaceutical and medical benefits.

“…Saify ZS et al (2000) found that the lipid content in the liver of Hammer-headed Shark Eusphyra blochii (66.19 %) was higher than that of shark Carcharhinus bleekeri (39.94 %). 47 Similarly, 48 reported that oil extracted from the liver of ray fish Himantura bleekeri confirmed that the liver is relatively rich in lipids which implies 54 % of the fresh matter containing lipids. In accordance with previous studies, lipid content of other elasmo branch livers was ranging from 23 to 67 % 49, [50][51][52][53] reported that the lipid content of liver of Dasyatis brevis and Gymnura marmorata as 50.80 % and 51.50 % of the total lipids respectively.…”

In the present investigation, the hooded cuttlefish Sepia prashadi were collected from Mudasalodai landing centre, east coast of Tamil Nadu, India. Collected animals were dissected for their liver (digestive gland) and the dried liver was ground well and the cuttlefish liver oil was extracted. The percentage of oil yield was noted as 32.45 %. The extracted liver oil was used for estimating total lipids, triglycerides, total cholesterol, High Density Lipoproteins cholesterol (HDL), Low Density Lipoproteins cholesterol (LDL), Very Low Density Lipoproteins cholesterol (VLDL) and free fatty acids. The fatty acid composition of the liver oil such as Saturated Fatty Acids (SFA), Mono Unsaturated Fatty acids (MUFA) and Poly Unsaturated Fatty acids (PUFA) was analyzed using GC-MIS. The results of the present study revealed that the cuttlefish (S. prashadi) liver oil was found to contain more MUFA and also contain considerable amount of triglycerides and cholesterol. The cuttlefish oil can be used as a bio enrichment of live feeds and the residual waste during oil production can be used as manure, poultry feed, bio diesel production, etc. Moreover production of oil from the animal wastes such as liver is an eco-friendly process and can reduce the environment pollution. The quality of oil can be improved to increase the PUFA content for human consumption. Apart from all the above advantages, cuttlefish oil can be used as an alternative to fish oil, as it is very easy and cheap to produce than the fish oils.
