Lipids extracted from three tilapia species (Oreochromis niloticus, O. macrochir and Tilapia rendalli) of mean weight 100–250 g collected in Itasy lake of Madagascar highlands during three seasons, were analyzed for their fatty acid compositions. The muscle fishes contained less than 1.4% lipid by weight. Gas chromatography (GC) and gas chromatography–mass spectrometry (GC–MS), allowed identification of more than 40 fatty acids and 30 of them were quantified in muscle tissue lipids of fishes… Expand
The fatty acid profiles and energetic substrates of two Nile tilapia (Oreochromis niloticus, Linnaeus) strains, Red-Stirling and Chitralada, and their hybrid
The results showed that changes in the metabolic processes occur during an increase in body mass in both varieties of tilapia and also their hybrid, but that these diierences are not found in animals collected at the commercial weight. Expand
Fatty acids composition in South African freshwater fish as indicators of food quality
The study points out that all fish species investigated contain appreciable levels of Omega-3 (n-3) polyunsaturated fatty acids (PUFA) and are therefore suitable for an unsaturated low-fat diet and is important especially for poor communities who cannot afford to get a balanced diet, rich in some essential fatty acids.

Muscle Lipids and Fatty Acid Profiles of the Sea Catfish (Arius madagascariensis) in Madagascar Inland Waters
Results indicate that A. madagascariensis, an abundant freshwater fish in Madagascar rivers, may be good source of dietary PUFA. Expand
Fatty acid profiles and fat contents of commercially important fish from Vistula Lagoon.
Investigations were conducted for fat content and fatty acids composition of six of the most frequently fished species inhabiting the Vistula Lagoon (bream, roach, perch, pikeperch, herring, and eel), finding that PUFAs had a high share of acids from the n-3 family, especially of eicosapentaenoic and docosahexaenoic acids.

Changes during fishing season in the fat content and fatty acid profile of edible muscle, liver and gonads of anchovy (Engraulis encrasicolus) caught in the Turkish Black Sea
It is indicated that anchovy is a good nutritional source for human consumption with high contents of omega 3 fatty acids, particularly during winter. Expand
Fatty acid composition of three freshwater fishes under different storage and cooking processes
Abstract Fatty acid composition of common carp (Cyprinus carpio), Nile tilapia (Oreochromis niloticus) and tambacu, a hybrid of tambaqui (Colossoma macropomum) and pacu (Piaractus mesopotamicus), wasExpand
Fatty‐Acid Profile of Total and Polar Lipids in Cultured Rainbow Trout (Oncorhynchus mykiss) Raised in Freshwater and Seawater (Croatia) Determined by Transmethylation Method
High n‐3/n‐6 ratio in total lipids and polar lipids of rainbow trout from SW and FW, besides beneficial n‐0.3/ n‐5 ratio in the commercial fish food, could be characteristic for the local environmental conditions (Croatia). Expand
Determination of the seasonal changes on total fatty acid composition and ω3/ω6 ratios of carp (Cyprinus carpio L.) muscle lipids in Beysehir Lake (Turkey).
It was shown that the fatty acid composition in the muscle of carp was significantly influenced by feeding period and seasons and also the monounsaturated fatty acids of carp in spring and summer. Expand
Influence of diets enriched with different vegetable oils on the performance and fatty acid profile of Nile tilapia ( Oreochromis niloticus ) fingerlings
The fatty acid profile of the carcass of Nile tilapia (Oreochromis niloticus) fingerlings fed diets enriched with different soybean, canola, sunflower, flaxseed, rice, and corn oils was examined. TheExpand
Fatty acids of neutral and phospholipids of three endangered trout: Salmo trutta caspius Kessler, Salmo trutta labrax Pallas and Salmo trutta macrostigma Dumeril
The highest n-3/n-6 ratios and eicosapentaenoic acid (EPA) + DHA amounts were found in the winter and this coincided with the lowest gonado-somatic index. Expand


The influence of feed supply time on the fatty acid profile of Nile tilapia (Oreochromis niloticus) fed on a diet enriched with n-3 fatty acids
Abstract The purpose of the study was to examine the fatty acid profiles of Nile tilapia ( Oreochromis niloticus ) submitted to different feeding times (0, 10, 20 and 30 days) on a diet enriched withExpand
Lipids and fatty acids in muscle, liver and skin of three edible fish from the Senegalese coast: Sardinella maderensis, Sardinella aurita and Cephalopholis taeniops.
Lipid content and fatty acid composition were determined in three species of edible fish caught in Senegalese waters during the upwelling season (January, 1993) and the percentages of PUFA found in the fish studied were very similar to those in fish used commercially as sources ofPUFA. Expand
Fatty acid content of some freshwater fish of commercial importance from tropical lakes in the Ethiopian Rift Valley
The data show that tropical freshwater fish are comparable to temperate freshwater fish as sources of polyunsaturated FA and Oreochromis niloticus from Lake Haiq was found to be superior in lipid quality to all the tropical fish species considered in this study. Expand
Changes in the fatty acid profiles of hybrid red tilapia, Oreochromis mossambicus X O. niloticus, subjected to short-term starvation, and a comparison with changes in seawater raised fish
Principal component analysis of the fatty acids data effectively summarized the major differences among the experimental treatments, which included substantial differences in the fatty acid profiles between sexes, fed and starved animals and between fish raised in fresh- and seawater. Expand
The influence of season on the lipid profiles of five commercially important species of Brazilian fish
The sardine, the croaker, the tilapia and the curimbata were not influenced by seasonality in terms of their total saturated and unsaturated acid contents, and the shrimp presented the highest cholesterol contents. Expand
Fatty acid composition of Tilapia
The fatty acid composition of different parts of tilapia was analyzed by gas chromatography. The result shows that the main fatty acids of tilapia are C16:0, C16:1, C18:0, C18:1 and C18:2, and theExpand
Lipid contents and fatty acid composition of some New Zealand freshwater finfish and marine finfish, shellfish, and roes
Abstract Lipid and fatty acid levels in the edible flesh of 6 freshwater finfish, 60 marine finfish, 9 molluscs, 3 crustaceans, and 6 fish roes from the New Zealand fishing area were determined.Expand
Characteristics of the fatty acid composition and biochemistry of some fresh-water fish oils and lipids in comparison with marine oils and lipids.
The fatty acid composition of oils from four North American fresh-water fish were compared with recent data for oils from two marine species, suggesting a basic difference in dietary availability of these two acids. Expand
Fatty acid distribution in muscle, liver, and gonads of rays (Dasyatis marmorata, Rhinobatos cemiculus, and Rhinoptera marginata) from the East Tropical Atlantic Ocean.
The results show that rays are potential resources of polyunsaturated fatty acids (PUFA) and should be used in the diet of local populations, and some of them are preferentially present in one sex or in both species. Expand
