“…Furthermore, pike perch fed on formulated diets showed increased HSIs (1.99 and 2.05), which indicate that high amounts of non-protein energy in the diet influence liver status and body composition. This relationship between dietary lipid content and body fat accumulation, especially in the liver, is a major concern in the nutrition of percids and some other cool-water species such as sunshine bass , hybrid striped bass , yellow perch (Brown et al 1996) and gilthead sea bream (Ibeas et al 1994). Pike perch fingerlings fed with formulated diets seem to utilise protein most efficiently, and excess dietary protein is catabolised preferentially over lipids and carbohydrates for energy metabolism, as is described by Wilson (1989).…”

To assess the effect of dietary composition on growth performance and body composition of pike perch (Sander lucioperca), fingerlings with an initial body weight of 1.36 g (just trained to accept formulated feed) were fed three experimental diets in triplicate for 90 days. Two feeding groups were fed with formulated diets (CD, CD+7) containing varying levels of crude lipid (CL) of 14.65% and 21.94% dry matter (d.m.) with crude protein (CP) levels of 59.73% and 56.56%, and one feeding group was fed a natural diet (chironomids, CP = 65.93% d.m.; CL = 7.20% d.m.). Furthermore, pike perch of the same age caught in different natural habitats were analysed to determine their naturally fluctuations in body composition. Specific growth rate (SGR; CD = 3.36, CD+7 = 3.47) and feed conversion ratio (FCR; CD = 1.02, CD+7 = 0.93) of fish fed formulated diets did not differ significantly with rising dietary lipid content, due to high variability within the individuals of each feeding groups. In contrast, pike perch fed with chironomids showed a significantly lower SGR of 2.49 and higher FCR of 2.37 (on a dry matter basis). Body composition of pike perch fed formulated diets was affected by dietary composition and showed increased lipid contents [CD=6.25% original matter (o.m.), CD+7 = 9.00% o.m.] with rising dietary lipid levels. Pike perch of CD and CD+7 feeding groups showed significant increased hepatosomatic indices (HSIs) of 1.99 and 2.05 in contrast to fish fed chironomids with HSI of 1.11. Fish caught in the different natural habitats were characterised by low body lipid and dry matter contents of 0.64-1.88% o.m. and 21.08-23.75% o.m. Higher lipid incorporation of fish fed with formulated diets accompanied with poor benefit on growth performance at higher dietary lipid content indicated that pike perch ability to utilise lipids is low when dietary crude protein content is higher than 56.56%.

“…In gilthead sea bream (Sparus auratus) for example, stepwise increase in various plant oils to 80% of lipid caused reductions in both alternative complement pathway and head kidney phagocytic activity while moderate replacements have very few immunologic effects Wassef et al 2007). The most extreme groups of fish had a content of 22:6n-3 and 20:5n-3 amounting to 7% of lipid or 0.6 and 1.1% of diet respectively, which is very close to EFA deficiency in this species (Kalogeropoulos et al 1992;Ibeas et al 1994;. Reductions in the number of circulating leucocytes and macrophages have been noted in European sea bass (Dicentrarchus labrax) fed diets with 60% replacements of fish oils (Mourente et al 2005a).…”

“…Two sardine-meal based diets were prepared with the same proximal composition and one was supplemented with 150 mg alpha-tocopherol kg 1 diet (control diet C). The diets were formulated to cover the n-3 HUFA requirements for this species (Ibeas et al, 1994). The analysis of the diets showed that the non-supplemented diet (NE) had low levels of vitamin E ( Table 2).…”
