Optimal dietary protein and lipid levels for juvenile cobia (Rachycentron canadum)

Linking fatty acids in the diet and tissues to quality of larval southern flounder (Paralichthys lethostigma)

“…This is similar to other studies that showed that survival increases with crude lipid up to an asymptote (Chou et al, 2001;Zheng et al, 2010). Interestingly, we found no relationship between survival and levels of individual fatty acids in the diet despite previous research suggesting that regulation of stress by essential fatty acids could affect survival (Watanabe 1993, Izquierdo 2005.…”

Effects of dietary lipid levels on growth, survival and lipid metabolism during early ontogeny of Pelteobagrus vachelli larvae

“…Similar results were reported in large yellow croaker larvae which had significantly higher survival when fed a diet containing 164 g lipid kg − 1 compared to those fed 83, 126 or 248 g lipid kg − 1 (Ai et al, 2008). High dietary lipid resulted in lower survival and reduced growth in the present study and some previous reports including yellow croaker larvae (Ai et al, 2008) and juvenile cobia (Chou et al, 2001) and on-growing turbot (Regost et al, 2001). This could be due to increased malonaldehyde in oxidized lipid, which is toxic to fish (Baker and Davies, 1997).…”

Physiological roles of fatty acyl desaturases and elongases in marine fish: Characterisation of cDNAs of fatty acyl Δ6 desaturase and elovl5 elongase of cobia (Rachycentron canadum)

“…There have been several trials investigating aspects of lipid nutrition in cobia including dietary protein and lipid levels (Chou et al, 2001;Wang et al, 2005), digestibility (Zhou et al, 2004) and larval development (Turner and Rooker, 2005). However, it is very important to appreciate that the current activities focussed on developing a viable cobia farming industry, growing fish from egg to market size, are taking place at a time when the aquaculture nutrition industry is currently going through major changes.…”
