“…Among the lipids, certain essential fatty acids (EFAs) and sterols are considered to be important drivers of ecosystem health and stability [18,19], but despite years of research, they remain among the least well-understood nutrients for aquatic animals [20][21][22][23][24]. EFAs and sterols are essential nutrients in marine bivalves and crustaceans [23,24] Figure 2: TLC/FID chromatograms of lipid classes in a standard and as part of a study of the effects of produced water from oil and gas production on cod [17].…”

Lipids provide the densest form of energy in marine ecosystems. They are also a solvent and absorption carrier for organic contaminants and thus can be drivers of pollutant bioaccumulation. Among the lipids, certain essential fatty acids and sterols are considered to be important determinants of ecosystem health and stability. Fatty acids and sterols are also susceptible to oxidative damage leading to cytotoxicity and a decrease in membrane fluidity. The physical characteristics of biological membranes can be defended from the influence of changing temperature, pressure, or lipid peroxidation by altering the fatty acid and sterol composition of the lipid bilayer. Marine lipids are also a valuable tool to measure inputs, cycling, and loss of materials. Their heterogeneous nature makes them versatile biomarkers that are widely used in marine trophic studies, often with the help of multivariate statistics, to delineate carbon cycling and transfer of materials. Principal components analysis has a strong following as it permits data reduction and an objective interpretation of results, but several more sophisticated multivariate analyses which are more quantitative are emerging too. Integrating stable isotope and lipid data can facilitate the interpretation of both data sets and can provide a quantitative estimate of transfer across trophic levels.

“…Aquatic ecosystems are known to be the main source of essential long chain n-3 PUFAs in biosphere, thereby humans obtain principal part of EPA and DHA by consuming fish, no other food group is naturally as rich in long chain n-3 PUFA as are fish, macro algae and other seafood [7,8].…”

“…The market value of cultured fish largely depends on their quality and feed composition is one of the factors that control quality [8,9]. It is currently well established that increased fish consumption in human is associated with decreased mortality, as well as morbidity from cardiovascular disease (CVD) and coronary heart disease (CHD) [10,11]. Consequently, the links between fish as food and human health are strongly related to the fatty acid composition of the food [12][13][14].…”
