Abstract A 9-week growth trial was conducted to investigate the effects of dietary cholesterol supplementation on growth performance, feed intake and cholesterol metabolism of juvenile turbot ( Scophthalmus maximus L.) fed high plant protein diets. A fish meal diet (diet FM) with 58% FM was formulated, and this diet was used as control. The other four diets were formulated to contain 14.5% FM, 42.0% soybean meal (SBM), and 18.5% wheat gluten meal. The four diets were supplemented with 0.0%, 0.5%, 1.0% and 1.5% cholesterol, respectively, and were isonitrogenous and isolipidic to the diet FM. They were named as diet C-0.0%, C-0.5%, C-1.0% and C-1.5%, respectively. The final dietary cholesterol concentrations were 0.30%, 0.77%, 1.25%, and 1.78%, respectively. That in control diet was 0.63%. The results showed that weight gain rate (WGR) and feed efficiency rate in fish fed diet FM were significantly higher than those in fish fed other diets ( P P P

Abstract A trial on turbot ( Psetta maxima ) juveniles was undertaken to evaluate the effect of replacing dietary fishmeal (FM) with a complementary mixture of plant proteins (PP) consisting of soybean meal (SBM), wheat gluten meal (WGM) and corn gluten meal (CGM). Four practical diets were formulated to progressively replace 25% (PP25), 39% (PP39), 52% (PP52) and 66% (PP66) of FM protein. Forty animals per tank (initial weight 24.2 ± 4.4 g) were randomly distributed into twelve 450-liter square...

In the present study, porcine liver microsomes prepared by a conventional ultracentrifugation method were compared with microsomes prepared by a calcium aggregation method. Protein concentrations and activities of several cytochrome P450 enzymes were measured. It was concluded that using a calcium aggregation method for microsome preparation resulted in lower activities of porcine 7-ethoxyresorufin O-deethylase (EROD), 7-methoxyresorufin O-demethylase (MROD), 7-pentoxyresorufin O-depentylase (PR...

Abstract A growth trial was conducted with the aim of developing a practical, environmentally sustainable and cost-effective plant-protein-based diet for Senegalese sole juveniles without compromising growth or protein deposition. A reference diet contained fish meal as the main protein source (F45, containing 37% fish meal and 45% of the dietary protein being from marine sources) and four plant-protein diets either containing 5% (F15) or no fishmeal (F5). The F15 diet also contained 5% hydrolys...

Abstract An experiment was conducted to determine the dietary cholesterol requirement of juvenile abalone Haliotis discus hannai . Eight isoenergetic (18.15–18.61 kJ/g) and isonitrogenous (29.00–29.78% protein) diets, supplemented with 0.00, 0.15, 0.30, 0.45, 0.60, 0.75, 0.90 and 1.05% cholesterol were evaluated. Juvenile abalone (initial weight: 0.67–0.72 g) were reared in a flow-through water system for 24 weeks. During the feeding trial, water temperature was maintained at 14–17 °C, salinity ...

Abstract Two consecutive feeding trials were conducted to determine the optimum dietary level of the cottonseed and soybean meal (CS) for replacement of fish meal (FM) in diets for juvenile and ongrowing parrot fish with or without iron and phytase. In experiment I, juvenile parrot fish (BW: 3.17 g) were fed one of six experimental diets for 12 weeks which were formulated to replace FM protein by equal proportion (1:1, w:w) of CS at 0, 10, 20, 30, 40, or 50% (designated as CS0, CS10, CS20, CS30,...

Abstract The finfish and crustacean aquaculture sector is still highly dependent upon marine capture fisheries for sourcing key dietary nutrient inputs, including fish meal and fish oil. This dependency is particularly strong within compound aquafeeds for farmed carnivorous finfish species and marine shrimp. Results are presented concerning the responses received from a global survey conducted between December 2006 and October 2007 concerning the use of fish meal and fish oil within compound aqu...

Abstract A regression design with increasing levels of a plant protein mixture replacing fish meal in diets for Atlantic cod, was used to elucidate effects on growth, feed utilization (FCR), digestibility (ADC), and retention of nutrients (PER, PPV and HSI). The plant protein diets contained soybean meal, soy protein concentrate and wheat gluten meal, all of high quality, and were added crystalline methionine and lysine to achieve levels of indispensable amino acids for maximizing growth in othe...

Abstract Carbohydrates are the cheapest source of dietary energy for fish. Utilization of carbohydrates in feed is beneficial to sparing protein consumption as energy source and saving feed cost. Therefore, 8-week feeding experiment was conducted to investigate the effects of starch level on growth performance, antioxidant capacity, serum biochemical parameters, intestinal morphology and intestinal microbiota of Trachinotus ovatus. Six isonitrogenous and isolipidic diets (D1, D2, D3, D4, D5 and ...

Abstract Fish oil can not only provide energy for the growth and development of fish, but also constitute a variety of tissue and cellular structural components of fish. However, fish oil is easily oxidized in the process of feed processing, treatment and storage, which reduces the feed quality and threatens the health of fish. Therefore, the purpose of this study was to investigate the effects of different degrees of oxidation of fish oil in feed on fatty acid composition and lipid metabolism i...

Abstract A ten-week feeding trial on Monopterus albus (initial weight 24.02 ± 0.02 g) was conducted to evaluate effects of four isonitrogenous and isoenergetic diets in which different proportions of fish meal (0, 2.5 %, 5% and 7.5 %) were substituted with Hermetia illucens (HI) larvae meal, corresponding to dietary inclusion levels of 0 (FM), 5.26 % (HI5.26), 10.52 % (HI10.52) and 15.78 % (HI15.78). Compared with FM, weight gain rate and condition factor of M. albus and gumminess and adhesivene...
Abstract The effects of dietary cholesterol supplementation on growth, molting performance and ecdysteroid signal transduction of juvenile crayfish Procambarus clarkii (initial weight = 3.55 ± 0.03 g) were evaluated over a 6-week feeding trial. The crude protein and lipid level of basal diet was targeted at 27% and 6%, respectively. Five levels of supplemented cholesterol (0, 0.25, 0.50, 0.75, and 1.00%) resulted in diets analyzed to contain 0.06, 0.29, 0.54, 0.81, and 1.05% cholesterol. Final w...

With increasing levels of fish meal (FM) protein in aquafeeds being replaced with soybean meal (SBM) protein, understanding the molecular mechanisms involved in response to alternative diets has become a critical concern. Thus, the goal of this study was to examine transcriptional differences in the intestine of juvenile yellow perch through RNA-sequencing (RNA-seq), after their initial introduction to a formulated diet with 75% SBM protein inclusion for 61 days, compared to those fed a traditio...

Abstract The aim of this study was to investigate the effects of methionine and taurine supplementation (individually or in combination at individual levels of 10 g/kg) on growth performance and lipid metabolism in juvenile California Yellowtail. A total of 4 dietary treatments were designed as CONTROL, MET, TAU and MET+TAU. After 6 weeks, production performance was significantly increased by dietary taurine and no synergetic effect of dietary taurine-methionine was noticed. Supplementation of m...
