“…The presence of these vacuoles can be interpreted as a temporary accumulation form of esterified fatty acids (Fontagné et al, 1998) and may occur due to various disturbances in lipid transport from enterocytes to the circulatory system. Smaller lipid droplets were observed in the enterocytes of fish fed EFA-enriched Artemia, implying positive influence of the EFA.…”

The aim of this study was to compare the physiology and morphology of the digestive tract of Russian sturgeon (Acipenser gueldenstaedtii) larvae fed Artemia sp. nauplii enriched or non-enriched with essential fatty acids (EFA). Physiology was evaluated by digestive enzyme activity analysis, while morphology was assessed with histological methods. The larvae were divided into two groups, in which fish were fed either pure Artemia sp. nauplii or Artemia enriched in EFA. Both groups had similar survival rates, but fish fed EFA-enriched Artemia displayed higher, body weight and length. At the end of the experiment (22 dph): 1) the activities of lipase and leucine aminopeptidase were similar in both groups; 2) the activities of trypsin, alkaline phosphatase and γ-glutamyltransferase were insignificantly higher in fish fed pure Artemia; 3) the activity of α-amylase was significantly higher in the EFA-enriched feeding group; 4) lower hepatocyte lipid vacuole diameters and hepatocyte proliferation were measured in the EFA-enriched group. Lipid accumulation was observed in the anterior intestine of fish fed pure Artemia on the 15 th and 22 nd dph. The epithelial turnover was significantly lower in the EFAenriched group, in the posterior intestine on the 15 th dph, but no differences occurred between the groups on the 22 nd dph, in either anterior or posterior intestine. In conclusion, the study revealed a positive effect of the EFA-enriched Artemia-based diet on the physiology and morphology of the digestive system of Russian sturgeon larvae.

“…However, there is now considerable evidence that at least some species of fish larvae, both freshwater and marine, may have only a limited capacity to biosynthesise phosphoglycerides de novo (Geurden et al, 1995Coutteau et al, 1997;Fontagne et al, 1998). This reflects the fact that many fish larvae receive an abundance of phosphoglycerides in their natural diets, whether from yolk sac lipids prior to first feeding or from natural prey at and after first feeding.…”

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.

“…However, PL may also be required for emulgating properties in the gastrointestinal tract, increasing the efficacy of intestinal lipases (Olsen et al 1991a,b;Coutteau et al 1997;Izquierdo et al 2001b). Positive effect of PL is not limited to juvenile marine fish, and PL has been shown both to remove lipid droplets and enhance growth in for example carp (Geurden et al 1995;Fontagne et al 1998;Geurden et al 1998). There is less information for salmonid fish.…”
