Effect of partial fish meal replacement by soybean meal on the growth performance and biochemical indices of juvenile Japanese flounder Paralichthys olivaceus

Abstract

A feeding trial was conducted to investigate the effect of partial fish meal (FM) replacement by dietary soybean meal (SBM) on the growth and protein and lipid metabolism of the juvenile Japanese flounder. Four isonitrogenous and isolipidic diets (Diets 1-4) were formulated containing 47% protein and 9% lipid with different SBM inclusion (Diet 1, 11%; Diet 2, 16%; Diet 3, 24%; and Diet 4, 41%). The fish were fed to satiation twice daily for a feeding period of 56 days. The weight gain rate (WGR) and protein efficiency ratio of fish fed Diet 4 were significantly lower than those fed Diets 1, 2, and 3, and feed conversion ratio in the group fed Diet 4 was significantly higher than that in the groups fed Diets 1, 2, and 3. Hepatosomatic indices showed the similar trend as WGR, and the value (1.75%) for Diet 1 was significantly lower than that (1.96-2.2%) for other diets. There were no differences in whole body moisture, crude protein, crude lipid, and ash content among all treatments. With increasing dietary SBM level, serum triglyceride (TG), cholesterol (CHO), and low-density lipoprotein cholesterol (LDL-C) concentrations increased, whereas the serum total protein (TP) and high-density lipoprotein cholesterol (HDL-C) concentrations decreased. Compared with Diet 1, the serum TG, CHO, and LDL-C concentrations of fish fed Diet 4 significantly increased by 78, 37, and 36%, respectively, while the TP and HDL-C concentrations decreased by 14 and 33%, respectively. No significant differences in condition factor, blood urea nitrogen concentration, and alanine and aspartate aminotransferase activities were observed among the dietary treatments. These results indicated that dietary SBM inclusion above 24% could adversely affect the growth and protein and lipid metabolism of Japanese flounder.

Growth performance, body composition, hematological, and serum biochemical responses of beluga (Huso huso) juveniles to different dietary inclusion levels of faba bean (Vicia faba) meal

“…These findings are consistent with previous findings on the substitution of plant proteins in Persian sturgeon (Imanpoor et al 2010) and beluga (Hosseini and Khajepour 2013). However, a decreasing trend (but significant between treatments) in total serum protein levels was previously reported through fish meal replacement by soybean meal in the diet of Japanese flounder (Paralichthys olivaceus) juveniles (Ye et al 2011) and also an increasing trend via dehulled lupin inclusion in rainbow trout diet (Farhangi and Carter 2001).…”

Effects of Dietary Quercetin on Growth Performance, Serum Lipids Level and Body Composition of Tilapia (Oreochromis Niloticus)

“…Consequently, the lipids lowering effects of quercetin might appear in tilapia, which is helpful to fish health. The increase in blood lipids parameters including triglyceride (TG), total cholesterol (TC) and low-density lipoprotein cholesterol (LDL-C) and the decrease of high-density lipoprotein cholesterol (HDL-C) implied that the fish might have had some disorder in lipid metabolism, leading to hyperlipidemia (Kritchevsky, 1995;Ye et al, 2011). The importance of tilapia as a component of global aquaculture has increased over the past several decades (Sarker et al, 2012), it can be a good trial animal to study the responses of dietary quercetin in fish.…”

Interactive effects of dietary arginine and histidine on the performances of Japanese flounder Paralichthys olivaceus juveniles

“…Japanese flounder Paralichthys olivaceus is an important cultured fish species in the Far East area, including China, Japan and South Korea (Kawamura and Hosoya, 1997;Ye et al, 2011a). Requirements of several essential amino acids were investigated on the Japanese flounder, such as lysine (Forster and Ogata, 1998), methionine (Alam et al, 2000), arginine (Alam et al, 2002a).…”
