Replacement of fishmeal with rice protein concentrate in practical diets for European sea bassDicentrarchus labraxreared at winter temperatures

Abstract

els test the efficacy of additional amino acid supplementation (e.g. tryptophan).

Effects of complete fish meal replacement by rice protein concentrate with or without lysine supplement on growth performance, muscle development and flesh quality of blunt snout bream (Megalobrama amblycephala )

“…This is in agreement with that of Güroy et al. (), who observed no significant difference in whole‐body composition of sea bass ( Dicentrarchus labrax ) when fish meal was replaced by RPC with or without lysine and methionine supplement. The results indicated that the substitution of fish meal by RPC might have little influence on the proximate composition of fish.…”

“…In addition, decreased nutrient digestibility could also explain for the poor growth performance. In fact, decreased nutrient digestibility coefficients were observed in both European sea bass ( Dicentrarchus labrax ) (Güroy et al., ) and Pacific white shrimp ( Litopenaeus vannamei , Boone, 1931) (Oujifard et al., ) fed diets with increasing levels of RPC. Besides, the good growth performance observed in fish fed FM diet might also be ascribed to the higher highly unsaturated fatty acid contents of fish meal than RPC (Oujifard et al., ).…”

“…However, considering its large annual production (nearly 0.8 million tons/year) (Ministry of Agriculture of the People's Republic of China ), even low inclusion rates add up to a substantial portion of fish meal consumption (Chiu et al., ). Otherwise, RPC is mainly applied to the practical diets of carnivorous fish and shrimp (Güroy et al., ; Oujifard, Seyfabadi, Kenari, & Rezaei, ), while little study was conducted on herbivorous fish. In addition, global rice production is enormous, suggesting that rice protein has a great deal of potential to be an extensive and functional protein source.…”

Nutrition of red drum,Sciaenops ocellatusL.: An additional evaluation of the effects of soya-based diets and supplemental prebiotic

“…chrysops (Rafinesque) fed the same diets in a previous evaluation (Rossi, Tomasso & Gatlin, ). Although lysozyme activity reported in similar studies is quite inconsistent as it has been shown to either increase (Estévez et al., ), decrease (Geay et al., ; Lin & Luo, ; Rossi et al., ) or be unaffected (Gause & Trushenski, ; Güroy et al., ; Kokou, Rigos, Henry, Kentouri & Alexis, ; Rossi, Tomasso & Gatlin, ; Sitjà‐Bobadilla et al., ) in response to plant‐based diets, reports of decreasing plasma glucose have been more consistent across studies (Gómez‐Requeni et al., ; Hansen, Rosenlund, Karlsen, Koppe & Hemre, ; Zhou, Mai, Tan & Liu, ). In addition, contrary to the lack of dietary effect on plasma lactate in the study of Trushenski et al.…”
