“…Thus, triacylglycerols constitute about 85%, 52%, 22% and 11% of chylomicrons, VLDL, LDL and HDL, respectively, in trout, whereas phospholipids account for 8%, 19%, 27% and 32% of the total weight of those lipoproteins (Babin and Vernier 1989). Generally, similar compositions were found in serum VLDL, LDL and HDL from Pacific sardine (Sardinops caerulea), HDL from pink salmon and chum salmon (Oncorhynchus keta), and serum lipoproteins from red sea bream and sea bass (Dicentrarchus labrax) (Ando and Hatano, 1988;Iijima et al, 1995;Santulli et al, 1997).…”

Lipids and their constituent fatty acids are, along with proteins, the major organic constituents of fish, and they play major roles as sources of metabolic energy for growth including reproduction, and movement including migration. Furthermore, the fatty acids of fish lipids are rich in ω3 long chain, highly unsaturated fatty acids (n-3 HUFA) that have particularly important roles in animal nutrition, including fish and human nutrition, reflecting their roles in critical physiological processes. Indeed, fish are the most important food source of these vital nutrients for man Thus, the long standing interest in fish lipids stems from their abundance and their uniqueness. This review attempts to summarise our present state of knowledge of various aspects of the basic biochemistry, metabolism and functions of fatty acids, and the lipids they constitute part of, in fish, seeking where possible to relate that understanding as much to fish in their natural environment as to farmed fish. In doing so, it highlights the areas that require to be investigated in greater depth and also the increasing application of molecular technologies in fish lipid metabolism which will fascilitate further advances through molecular biological and genetic techniques including genomics and proteomics.

“…Plasma lipoprotein profiles of fish seemed to depend on the storage sites of lipid. Although the different classes of plasma lipoproteins such as VLDL, LDL, and HDL have been characterized in a number of fish species, most fish have been reported to possess HDL in their plasma as the main component (Chapman 1980;Amthauer et al 1989;Babin and Vernier 1989;lijima et al 1990, 1995MacFarlane et al 1990;Wallaert and Babin 1994). Taking into account that Japanese eels contained much more lipid in their muscle than in their liver, Japanese eels were expected to possess a unique lipoprotein profile in their plasma.…”

A unique lipoprotein profile was found in the plasma of cultured Japanese eel,Anguilla japonica which accumulated more lipid in its muscle than in its liver. The plasma lipoprotein level of Japanese eels was in excess of 54 mg ml(1), a concentration considered to be hyperlipoproteinemic in relation to other teleosts. The plasma lipoproteins consisted of very low density lipoprotein (VLDL, density (d)<1.006 g ml(1)) low density lipoprotein (LDL, 1.006

“…1995) have shown that the density intervals of each lipoprotein class and the distribution of their lipids and apolipoproteins generally resembled those observed in mammals. Fish lipoproteins are classified, similarly to mammals, as very low density lipoproteins (VLDL), intermediate density lipoproteins (IDL), low density lipoproteins (LDL) and high density lipoproteins (HDL) (Chapman 1980; Babin & Vernier 1989; Iijima et al. 1995).…”

The lipoprotein and lipid composition of the serum in postabsorptive haddock was characterized. A low level of very low density lipoproteins (VLDL; <50 mg dL−1) was observed in serum. High density lipoprotein (HDL) was the predominant lipoprotein class followed by low density lipoproteins (LDL). Of the lipoprotein classes, the highest proportions of triacylglycerol (28%) and phospholipid (64%) were observed in the lipid of VLDL and HDL, respectively. Serum lipid (48%), phospholipid (50%) cholesterol ester (65%) and HDL (51%) contained a high level of polyunsaturated FA, particularly eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA). Serum triacylglycerol (38%) and VLDL (36%) contained a lower proportion of polyunsaturated fatty acid. The phospholipid, triacylglycerol, cholesterol ester and cholesterol contents of the whole serum were 739, 214, 201 and 141 mg dL−1 respectively. On the basis of total acyl carbon number, the 38C (36%) and 36C (24%) molecules were the predominant phospholipids. The 50C (11%), 52C (17%), 54C (21%), 56C (21%) and 58C (15%) molecules were the major triacylglycerols. High molecular weight apo B‐like proteins were observed in the VLDL, LDL and intermediate density lipoprotein (IDL) fractions. An apo AI‐like protein was predominant in the HDL fraction. The prevalence of enlarged fatty livers in cultured gadoid fish (i.e. haddock and cod) is a major constraint to their commercialization and has been associated with the level of dietary lipid. Information on lipid (triacylglycerol) transport out of the liver through the serum as lipoproteins (VLDL) has implications for our understanding of fatty liver development in cultured gadoid fish. The low level of VLDL triacylglycerol (<12 mg dL−1) circulating in the serum of postabsorptive haddock suggests either a low level of lipid transport out of the liver as triacylglycerol or relatively rapid turn over of VLDL.
