“…In turn, Łuczyńska et al [2008] reported on a lower content The main fatty acids of n-3 PUFA in muscle lipids of fi sh were DHA (1.7-15.9%) and EPA (1.2-8.8%). These results are in accordance with literature data for marine fi sh [Njinkoué et al, 2002;Visentainer et al, 2007] and freshwater fi sh [Kujawa et al, 2005;Łuczyńska et al, 2008]. A higher value of DHA was observed in rainbow trout compared to the other fi sh studied (p≤0.01), while a higher content of EPA was found in bream (p≤0.01) ( Table 1).…”

The aim of the present study was to determine the profi le of fatty acids in muscle lipids of freshwater fi sh: carp (Cyprinus carpio L.), rainbow trout (Oncorhynchus mykiss Walb.), bream (Abramis brama L.) and tench (Tinca tinca L.) from markets of Olsztyn (north-eastern Poland). Separation and identifi cation of fatty acids were made using gas chromatography. The content of some fatty acids varied among species. Generally, palmitic acid (15.6%-19.5%) was the most abundant saturated fatty acid (SFA). The main monounsaturated fatty acid (MUFA) was oleic acid (20.7%-42.7%). Linoleic (4.6%-8.0%), arachidonic (AA) (0.8%-6.6%), docosahexaenoic (DHA) (1.7%-15.9%) and eicosapentaenoic (EPA) (1.2%-8.8%) acids were the predominant polyunsaturated fatty acids (PUFA). There were no signifi cant differences (p>0.05) in the content of SFA (24.3%-28.7%) among the fi sh species. The content of MUFA in muscle lipids of carp (55.0%) was signifi cantly higher (p≤0.01) than in the lipids of the other fi sh examined (35.8%-38.3%). Bream and rainbow trout (26.6% and 27.7%, respectively) contained signifi cant more n-3 PUFA than carp (4.7%) and tench (20.5%) (p≤0.01). Total n-6 PUFA ranged between 8.4% (rainbow trout) and 12.9% (tench). Signifi cant differences in n-6 PUFA content were only observed in the case of these fi sh (p≤0.01). The differences in the n-3/n-6 ratio (rainbow trout (3.3) > bream (2.6) > tench (1.6) > carp (0.4)) were statistically signifi cant (p≤0.01).

“…Although some data on the composition of viscera and livers from hake waste from other regions of the Atlantic have been reported (Grompone et al, 2004;Njinkoué et al, 2002;Mendez, 1997), we have found no data on that from hake waste from the Patagonian region. Both aquiculture and the demand for fish oil as an ingredient of a balanced diet are booming Food and Agriculture Organization of the United Nations, 2014), and the global production of fish oil is not enough to cover this demand Izquierdo et al, 2005).…”

SUMMARY:The fish processing operations in Patagonia produce large amounts of waste. The main fishery resource in Argentina is the Argentine hake (Merluccius hubbsi). The ports of the province of Chubut (the most important of which are Puerto Madryn, Rawson and Comodoro Rivadavia), together with Caleta Paula Port (province of Santa Cruz), in the Argentine Patagonia, capture more than 82,000 tons of hake annualy, 80% of which are of M. hubbsi, which is mostly converted into fillets. From this capture, about 2,296 tons of liver would be available for the extraction of oil. To promote the recovery and industrial use of fish oil, in the present study, we determined the variation in the proximate composition and fatty acid profile of Argentine hake waste from the ports mentioned above at different catch times. Proximate composition was determined according of the Official Methods of Analysis (AOAC). Fatty acid profile was analyzed by gas chromatography of the fatty acid methyl esters (FAMEs). A standard mixture of FAMEs was run under identical conditions to identify the compounds on the basis of their retention times. Fatty acids were quantified using heptadecanoic acid (C17:0) as internal standard. The highest lipid recovery (27.0 to 41.8% of total lipids) was obtained from the liver fraction. Palmitic acid (C16:0), oleic acid (18:1 n9), docosahexaenoic acid (22:6 n3), eicosapentaenoic acid (20:5 n3) and palmitoleic acid (16:1) were the main constituents. Protein levels in viscera without livers (V-L) were higher than those in the liver. The extraction of marine fish oil and the production of fish offal meal from waste from fish factories would contribute to the sustainability of the regional industry, because it would also decrease the volume of waste, with benefits to the environment.

El procesamiento de pescados en Patagonia produce gran cantidad de residuos. El recurso de pesca más importante en la Argentina es la merluza argentina (Merluccius hubbsi). En Patagonia, los puertos de la provincia del Chubut (de los cuales los más importantes son Puerto Madryn, Rawson y Comodoro Rivadavia), y Caleta Paula (provincia de Santa Cruz), capturan más de 82.000 t anuales de merluza, de las cuales el 80% corresponden a M. hubbsi. La misma es en su mayoría convertida en filetes. De esta captura, aproximadamente 2.296 toneladas de hígados estarían disponibles para la extracción de aceites. Para promover la recuperación y el uso industrial del aceite de pescado, se ha determinado la variación en la composición proximal de los residuos y el perfil de ácidos grasos de híga-dos de merluza argentina capturada en diferentes épocas en los puertos mencionados arriba. La variación en composición proximal fue determinada según la metodología propuesta por los Official Methods of Analysis (AOAC). El per...

“…These different FA were mostly due to the high values of PUFA as a result of the extremely high EPA values in 2007 (34.6 to 55.4%). In the literature, the EPA values for eggs, female gonads, or even other fish tissues (muscle, skin, liver) are usually < 20%, including aquaculture fish species fed special diets (Tocher & Sargent 1984, Navas et al 1997, Pickova et al 1997, Sargent et al 1999, Morehead et al 2001, Iverson et al 2002, Njinkoué et al 2002, Shirai et al 2002, Li et al 2005, Salze et al 2005, Bransden et al 2007, Garrido et al 2007, Huynh et al 2007, Özogul & Özogul 2007. Causes of our high values are not known but could be due to the combined effect of the direct ingestion of long chain-forming diatoms and large calanoid copepods, and the lower temperatures in 2007.…”

“…Examples of these range from demersal fishes (St. John & Lund 1996, Dwyer et al 2003 to mesopelagic myctophid fishes (Saito & Murata 1998) to forage fishes at high latitudes (Iverson et al 2002). A correspondence between the feeding environment and fish composition has also been observed in very productive zones such as upwelling areas (Lasker & Theilacker 1962) and could be a characteristic of planktivorous fish in short food web systems (Njinkoué et al 2002). The body tissues of female fish rapidly incorporate seasonal variations in food quality in terms of available FA.…”

We assessed the fatty acid (FA) composition of anchoveta eggs collected from the plankton along with female anchoveta reproductive traits and environmental conditions during peak winter spawning in 2005 and 2007. Environmental conditions differed markedly between years at 3 continental shelf stations off Talcahuano, Chile, with a warmer, fresher water column in 2005 and a colder, saltier one in 2007. We confirmed differences in sea surface temperature, measured both at the coastal egg collection stations and using satellite images over a broader area, caused by south
