“…This can be explained by a greater amount of DHA requirement of fish species used in the experiment, and attended to EPA and DHA synthesis of linolenic acid. It can be said that this result obtained with regard to DHA is similar to results obtained from different species grown in culture conditions such as Gilthead sea bream (Fountoulaki et al 2009;Diaz-Lopez et al 2010), Sea bass (Hunt and Tekelioglu, 2004;Dedeler, 2013;Eroldogan et al 2013;Ozsahinoglu et al 2013), Rainbow trout (Pettersson, Johnsson, Brannas & Pickova, 2009;Dernekbası, 2012) and Atlantic salmon (Bell, Henderson, Tocher & Sargen, 2004;Karalazos, 2007;Nanton et al 2007). Fish have high nutritional needs for EPA and DHA due to they contain these fatty acids at high amount in their body tissues (Sargent, McEvoy & Bell, 1997).…”

Black Sea trout (Salmo trutta labrax Pallas,1811) fed with diets based on 100% fish oil (FO), 67-33%, 50-50% and 33-67% soybean oil-linseed oil (SO-LO) during 90 days were affected in terms of weigth gain, specific growth rate, feed conversion ratio and hepatosomatix index significantly (P<0.05) while the survival rate was not affected at all. Tissue fatty acid profiles of the individuals were affected by the degree of dietary treatments (P<0.05). For instance, the highest linoleic acid (18:2n-6, LA) content of the muscle and liver tissues were exhibited in the group fed with 67-33 % SO-LO diet, where the highest linolenic acid (18:3n-3, LNA) was detected in the group fed with 33-67% SO-LO diet (P<0.05). In contrast to linoleic and linolenic acids, the highest values of palmitic (18:0), eicosepentaoneic (20:5n-3, EPA) and docohecsaenoic acids (22:6n-3, DHA) were indicated in group fed with fish oil based diet (P<0.05). Gene expression of desaturase in the muscle and liver tissues of individuals fed with 33-67% SO-LO included feeds were higher than those fed with FO. Similarly, gene expression of elongase both in the liver and muscle in individuals fed with (50-50% SO-LO, 33-67% SO-LO) and (50-50% SO-LO, 67-33% SO-LO) respectively were higher than those fed with FO. As a result, it was determined that use of 50-50% SO-LO in Black Sea trout diets is acceptable without an adverse effect on growth and feed conversion, and also this species have a capability of conversion 18:2n-6 to 20:4n-6 and 18:3n-3 to 22:6n-3.

“…In 54 papers the quantification method is described in details (i.e., use of internal standard and serially diluted mixtures of external standards, use of empirical or theoretical response factors for each FA, system calibration) (Bell and Dick 2004; Ludwig et al 2008; Lund et al 2008). Concerning the “unclear” group, in 80 papers, the use of an internal standard is mentioned but no further explanation of this use is provided (e.g., Garduño‐Lugo et al 2007; Ramos et al 2008; Díaz‐López et al 2009). Finally, in many of the papers (169 out of 394, 42.89%) the description of quantification is completely unclear as the only information usually provided is that FA were quantified “…by use of the xx software” or “…by integration of the peak areas” (Blanchard et al 2008; Benedito‐Palos et al 2009; Figueiredo‐Silva et al 2010).…”

“…Besides, when FA are presented as percentages without reporting actual totFA content of tissues examined, it is not possible to calculate absolute FA amounts. Lipid classes found in fish total lipids (particularly farmed fish) are triacylglycerides (and to a lesser degree diacyl‐ and monacyl‐glycerides), phosphoglycerides, sphingolipids, cholesterol, cholesterol esters, and free fatty acids (Tocher 2003; Díaz‐López et al 2009). From these only cholesterol does not contain fatty acids.…”

“…The relative contribution of these lipid classes within a specific tissue total lipid is affected by several factors such as fish species, life stage, diet, nutritional condition, physiological status etc. and thus may be subjected to differentiations due to the experimental treatment itself (Copeman and Parrish 2002; Zhu et al 2003; Díaz‐López et al 2009). The same stands for a tissue total amount of fatty acids (Kandemir and Polat 2007).…”

An Overview of the Use of Fatty Acids in Fish Farming Research during the Last Decade, with Particular Emphasis on Fish Quality

The present literature overview was carried out in order to assess the use of fatty acids (FA) analysis in fish farming research during the last decade. As aquaculture products are mainly intended for human consumption, the overview is focused on fish fillet, carcass or whole body FA, as a major aspect of fish nutritional value. This survey used 394 papers and demonstrated that a) 71% of papers report FA as relative percentage of total FA (% totFA), b) 23% of papers report actual FA amounts, c) in 63% of papers not enough information is provided in “Materials and Methods” section to understand exactly how FA analysis was performed, and d) based on FA percentages, results are not always the same as when based on FA amounts, and thus divergent conclusions about treatment effects could be drawn. These findings indicate that certain issues need to be addressed regarding adequate description of analytical methods followed for FA analysis, presentation and interpretation of FA results and may help to highlight critical points that should be considered from the researchers' and scientific journals' sides in order to foster more informative research publications.

“…It is widely accepted that fatty acid composition of tissues is influenced by the fatty acid composition of dietary lipids, and marine fish species have a specific requirements for the HUFAs 20:4n-6, 20:5n-3 and 22:6n-3 (Díaz- López et al 2010;Figueiredo-Silva et al 2010). In our study, the proportion of MUFA was found to decrease in tissues, while HUFA was selectively accumulated in muscle compared to the experimental diets (HUFA in liver was detected to stay roughly the same).…”

The present study aimed at determining the growth performance, feed utilization, body composition and antioxidant status of chu's croaker (Nibea coibor) juveniles fed with increasing levels of dietary lipid: 6 % (D6), 9 % (D9), 12 % (D12) and 15 % (D15). Each diet was assigned to triplicate groups of fish in a total of 12 floating pens (300 fish, 25 fish per pen). After a 49-day growth trial, survival rate was not affected. D12 and D15 led to significantly higher specific growth rate (SGR). Fish fed D12 showed the highest protein efficiency ratio (PER), protein and lipid retention efficiencies (PER and LRE, respectively). The hepatosomatic and viscerosomatic indexes (HIS and VSI, respectively) increased, while feed conversion ratio (FCR) and feed intake (FI) decreased. Body protein, ash and muscle lipid contents were not significantly affected, but significantly higher body and liver lipid were noticed in fish fed with D15. Monounsaturated fatty acid (MUFA) was found to decrease compared to the experimental diets in muscle, while high unsaturated fatty acid (HUFA) was selectively accumulated in all treatments. Serum alanine transaminase (ALT, 14.13-22.53 U/L), aspartate transaminase (AST, 34.31-51.25 U/L), cholesterol (CHO, 2.02-3.03 mmol/L) and triglyceride (TG, 5.61-8.50 mmol/L) were correlated with increasing dietary lipids. Liver malate dehydrogenase (MDA, 3.32-6.67 mmol/L) and superoxide dismutase (SOD, 42.69-52.86 U/mg prot) increased with dietary lipids, while total antioxidant capacity (t-AOC, 1.08-3.50 U/mg prot) decreased. Polynomial regression analyses between SGR and dietary lipid levels showed that the optimal dietary lipid requirement of chu's croaker is 12.9 % of dry matter.
