“…Sinanoglou and Miniadis-Meimaroglou (1998) and Passi et al (2002) state that wild cephalopods are characterized by relatively high DHA content and DHA/EPA ratio, these observations reflect the results found in our case for wild octopuses and those fed the mixed diet and bogues diet. It is known that the ratios between DHA and EPA are important for normal growth and development of cultured octopuses Villanueva 2000, 2003).…”

The influence of diet on growth and biochemical composition of cultured Octopus vulgaris was investigated. Octopuses were reared in a open recirculation seawater system and during the experiment were kept apart in cages. Experiment lasted 30 days. Three experimental dietary groups were established: group I (mixed diet: Carcinus mediterraneus, Boops boops and Mytilus galloprovincialis), group II (monodiet on B. boops) and group III (monodiet on M. galloprovincialis). The best results were obtained with the monodiet based on bogue that gave a weight gain of 390.65 ± 37.54, an absolute growth rate of 13.02 g day -1 and feed efficiency of 44.79 ± 0.96%. Regarding to biochemical composition, the mussel-fed and bogue-fed groups showed the highest protein content. Animals fed on bogue also showed the highest carbohydrate content, while the lowest value was observed in the mussels-fed group. The lipid content was found to be very low in all dietary groups. Saturated fatty acids were the most abundant fatty acid class, ranging from 58.22% in wild octopuses to 46.83% in bogues-fed octopuses. Polyunsaturated fatty acids (PUFAs) were the second most abundant fatty acids class in all dietary treatments (25.65-37.00% as a per cent of total FAs) except in octopuses fed with mussels. MUFAs ranged from 11.44 to 26.93% of total FAs. Although it is empirically known that a varied diet better covers the nutritional requirements than a monodiet, the results of this study reveal that a monodiet of B. boops may be used.

“…Fatty acid methyl esters (FAMEs) were prepared as previously described (Sinanoglou & Miniadis-Meimaroglou 1998). FAMEs were identified and quantified using an Agilent 6890 Series GC (Agilent Technologies, USA) with flame ionisation detector, according to the procedure of Sinanoglou et al (2013).…”

Sinanoglou V., Houhoula D., Kyrana V., Lougovois V. (2017): Visceral oil from farmed Sparus aurata, Dicentrarchus labrax and Diplodus puntazzo as a source of ω-3 PUFA. Czech J. Food Sci.,35: 414-423.Crude oils recovered from the viscera of conventionally and organically farmed gilthead sea bream (Sparus aurata), European seabass (Dicentrarchus labrax), and sharpsnout sea bream (Diplodus puntazzo) were characterised. Triacylglycerols (TAG) and phospholipids (PL) were the major lipid classes. Visceral oils contained high levels of n-3 polyunsaturated fatty acids (PUFA), in particular docosahexaenoic acid (DHA) and eicosapentaenoic acid (EPA). The DHA/EPA ratios (range 1.66-2.46) were higher in organically farmed fish. Total PUFA and n-3 fatty acid levels varied according to both species and rearing system, and were higher in the conventionally farmed sparids. The ratios of n-3 to n-6 PUFA (1.42-2.19) were comparable to the values reported for muscle lipids, while the PUFA/SFA ratios (1.07-1.33) exceeded the recommended value. Visceral oils exhibited good oxidative stability, as judged by monitoring lipid oxidation products during storage at 63°C. These data indicate that the viscera of all three species may represent a good source for the production of omega-3 rich oils.

“…Triglycerides have a close relationship with HDL cholesterol, and many of the factors that affect lowering HDL also affect the elevation of triglycerides. 57 found that the mantle of Eledone moschata (octopus) was rich in proportion of triglycerides (33 % of total lipids), which were found to contain a substantial proportion of n-3 polyunsaturated fatty acids. In contrast, Sepia officinalis and Todarodes sagittatus (squid) were found to contain low or minimal amounts of triglycerides (10 % and 1.4 % of total lipids, respectively) and only trace amounts of n-3 poly unsaturated fatty acids.…”

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.
