Influence of diet on proximate composition and fatty acid profile in common carp (Cyprinus carpio)

Interactive effects of dietary protein level and oil source on proximate composition and fatty acid composition in common carp (Cyprinus carpio L.)

“…Namely, increased level of carbohydrates resulted in increasing deposition of fat, both around visceral organs and in muscle tissue. Similar findings were noticed after the inclusion of carbohydraterich grains in the feed of common carp in a semi-intensive system (Vasha et al, 2007;Ljubojević et al, 2013b;Trbović et al, 2013). A negative correlation between the fat and water contents in the flesh of the carp was also previously shown (Ljubojević et al, 2013c,d).…”

Comparative study of the nutritional composition of wild versus farmed yellowtail (Seriola lalandi)

“…Such factors have resulted in large inter-study and inter-species variation in fish nutritional composition. Cyprinus carpio fed a low protein diet had increased fat and muscle moisture contents (Ljubojević et al, 2015) while C. carpio had higher levels of protein, lipid and ash when fed an extruded feed compared to a maize based diet (Trbović et al, 2013). In addition, Mohammad and Khalil (2013) observed that water temperature had positive and negative relationships on protein and fat contents of Mesopotamichthys sharpeyi muscle, respectively, whilst water temperature fluctuations can additionally affect the metabolic demand for body fat stores (Ibarz et al, 2005).…”

“…No significant difference (p N 0.05) between male and female yellowtail was apparent in the current study (preliminary analysis of farmed fish) and it is therefore unlikely to have contributed to the inter-group difference observed. Although details on diet information of the farmed and wild yellowtail were not available it is suggested that both groups (wild and farmed) had a dissimilar diet which likely contributed to the inter-group variation in the fatty acid composition as has been observed in other studies (Ljubojević et al, 2015;Trbović et al, 2013). In addition, the temperature difference between locations at the time of sampling (one-two degree Celsius) may also have affected the composition of the two groups.…”

Compound feeds and cereals as potential tools for improved carp Cyprinus carpio production

“…Compound feeds are now also used in carp nursery ponds and some carp cageculture units. In some countries, extruded and pelleted feeds are relatively widely used for carp aquaculture as they provide a higher level of weight gain (Ćirić et al 2015), improve meat quality (Mráz et al 2012, Trbović et al 2013, Živić et al 2014) and increase the abundance of natural food while lowering the abundance of nuisance cyanobacteria ( Ć irić et al 2015). Most studies dealing with compound feeds, however, have focused on the rearing of juvenile carp at high stocking densities (>1200 ind.…”
