“…All the other diets contained vegetable oils to substitute either 60% of the anchovy oil used in Diet FO, in diets 60SO (soybean oil), 60RO (rapeseed oil), 60LO (linseed oil), or 80% in diet 80LO (linseed oil). Fish oil was included in diets 60SO, 60RO, and 60LO at a level sufficient to meet the reported EFA requirements of this species (Lanari et al, 1999) (Table 2).…”

In the present study 75 g European sea bass were fed for 8 months with different diets (22% dietary lipid content) containing vegetable oils at two inclusion levels. The control diet (Diet FO) contained anchovy oil as the only lipid source; in diets 60RO, 60LO, and 60SO of fish oil was substituted by rapeseed, linseed or soybean oils, respectively; finally, in diet 80LO, 80% of the fish oil was substituted by linseed oil. Fish were fed to apparent satiation three times a day. All fish were individually weighed once per month. Lipid and fatty acid composition of diets and fish fillets were determined at the beginning, middle and end of the experimental period. Once the commercial size was reached, all fish were fed a 100% FO containing diet during 150 days.No significant differences were found in feed intake. Fish fed the diets containing 80% linseed oil or 60% rapeseed oil had significant ( P b 0.05) lower growth. Flesh fatty acid composition of total lipids reflected the fatty acids in the diets. Flesh contents of n-3 HUFA were reduced to about 45% in fish fed diets 60RO, 60LO or 60SO and to about 50% in diet 80LO. This reduction was markedly higher for EPA than for DHA. High levels of oleic, linoleic and linolenic acids were found in fish fed RO, SO and LO respectively.After 150 days of re-feeding period with a 100% fish oil diet, DHA levels were restored in those fish previously fed diets containing vegetable oils, but EPA levels remained lower when compared with fish fed 100% FO diet. Flesh content of linoleic and linolenic acids remained higher in those fish previously fed soybean and linseed oil containing diets, respectively.

“…Meagre is an emerging species in Mediterranean aquaculture with leanness as its most valuable trait (Poli et al, 2003;Hernandez et al, 2009) that distinguishes it from other marketable farmed fish (i.e., sea bream, sea bass, etc.) (Lanari et al, 1999;Poli et al, 2001). Less muscle fat than the amounts present in other aquacultured species permits refrigerated storage for longer periods of time.…”

The purpose of this study was to evaluate qualitative traits of meagre (Argyrosomus regius) from two different rearing systems (land-based tank filled with geothermal water vs offshore sea cage) and after short-term storage at chilling temperature (1, 2, or 3 days). Fish originated from the same batch were fed the same diet. Morpho-biometric traits, L*, a*, and b* colour parameters, texture, free water, proximate composition, total lipids, fatty acids, iron, and selenium contents were analyzed in the fillets. Most parameters were affected by rearing system. Compared to tank-reared fish, caged fish were shorter, poorer in visceral fat, and had higher incidence in cavity content and liver, lower incidence in gonads and head. Caged fish also had softer fillets in the epaxial site, which showed a higher tendency towards greenish colour. Caged fish also showed higher lipid content but lower Fe and Se content. Tank-reared fish fillets were more abundant in PUFAn-3, mainly due to DHA (18.54 vs 12.95%; P<0.001) and consequently showed the best healthiness indexes. Minimal changes, mostly involving colour and texture, were detected during the first three days of refrigerated storage. During storage, no significant modification of the parameters investigated could be ascribed to the rearing system.

“…The growth of juvenile Eurasian perch (BW ≈ 35 g) on a diet containing 19.3% lipids was higher than that of those administered the feed containing 11.7 or 15.0% lipids (Xu et al, 2001). In the case of sea bass, Dicentarchus labrax, a faster growth rate was also noted in fish that received a diet richer in lipids (19% versus 15 or 11%) (Lanari et al, 1999). Jobling et al (1998) did not observe that the dietary lipid levels had a significant effect on the amount of consumed feed or on the weight gains of juvenile rainbow trout, Oncorhynchus mykiss (BW ≈ 90 g), which received feed with either high or low lipid contents (27.5 versus 12.6%).…”

ABSTRACT:The aim of the experiment was to determine the effect of graded lipid content in experimental isoprotein feed (6, 10, 14% lipids and 45% protein) on the growth performance of juvenile pikeperch (initial body weight ≈ 210 g) in a recirculation system. No significant effect of the applied feed on the final average body weight was observed. However, average daily weight gain (g/d), SGR index (%/d) and condition coefficient of the fish receiving 10% lipid feed were significantly higher than the corresponding values in the other two groups (6 and 14% lipid, P < 0.05). Feed conversion ratio (FCR) and protein efficiency ratio (PER) a�ained the most advantageous values in this group of fish. The application of the experimental feed had a significant effect on the lipid values in fish bodies and viscera (P < 0.05) although no relationship was detected between the lipid content of the feed and that of the fish muscles. The lipid content was approximately 7.7% in all the experimental groups and the differences between the groups were statistically insignificant (P > 0.05).
