Abstract
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 31–33, pH 7.4–7.9. Abalone fed diet without cholesterol supplementation had the lowest weight gain ratio (WGR, 356.70%). Survival ranged from 98.52 to 100.00% and was not significantly different among treatments. There were no significant effects of dietary cholesterol on composition and cholesterol concentration in the muscle and viscera of abalone. Based on data of WGR using broken-line analysis, the optimal dietary cholesterol requirement of juvenile abalone was found to be 0.23%.

Juvenile abalone, Haliotis discus hannai Ino (initial mean body weight: 0.56 ± 0.01 g, shell length: 15.74± 0.13 mm) were fed six diets with graded levels of pyridoxine (PN) (0.40, 12.5, 22.7, 43.5, 87.8, and 172.2 mg/kg diet). Each diet was fed to three replicate groups of juvenile abalone for 16 wk. Dietary PN significantly (P < 0.05) affected abalone growth, tissue concentrations of PN and pyridoxal 5#-phosphate (PLP), and the activities of asparatate aminotransferase (AST) and alanine aminot...

Abstract A 152-day growth experiment was conducted in a recirculated water system to investigate the interaction between vitamins A (retinol) and D (cholecalciferol) on growth and metabolic responses in abalone Haliotis discus hannai Ino. Triplicate groups of juvenile abalone (initial weight: 0.35 ± 0.03 g; initial shell length: 11.31 ± 0.25 mm) were fed to satiation one of 16 semipurified diets containing 0, 1 × 103, 1 × 105, 1 × 106 IU/kg vitamin A and 0, 500, 1 × 103, 5 × 103 IU/kg vitamin D ...

Steroid molecules are present in all invertebrates, and some of them have established hormonal roles: this is the case for ecdysteroids in arthropods and, to a lesser extent, for vertebrate-type steroids in molluscs. Steroids are not only hormones, they may also fulfill many other functions in chemical communication, chemical defense or even digestive physiology. The increasing occurrence of endocrine disruption problems caused by environmental pollutants, which interfere in particular with repr...

While bile acids (BAs) have long been known to be essential in dietary lipid absorption and cholesterol catabolism, in recent years an important role for BAs as signalling molecules has emerged. BAs activate mitogen-activated protein kinase pathways, are ligands for the G-protein-coupled receptor (GPCR) TGR5 and activate nuclear hormone receptors such as farnesoid X receptor alpha (FXR-alpha; NR1H4). FXR-alpha regulates the enterohepatic recycling and biosynthesis of BAs by controlling the expre...

Metabolic responses of cholecalciferol (VD3) and minerals (Ca, P and Mg) in abalone Haliotis discus hannai Ino to dietary VD3 and phosphorus (P) were investigated. Based on a 2 × 2 factorial design, four casein-gelatin-based diets were formulated. The basal diet was supplemented with either 0 or 2000 IU VD3/kg diet and 0 or 10 g P/kg diet. The abalone was reared in P-free artificial seawater for 55 days. Results showed that dietary VD3 was hydroxylated to 25-hydroxyvitamin D3 [25(OH)D3] and 1α,2...

Sterol composition and content and their seasonal variations over 18 months were investigated in adductor muscle, digestive gland and gonads of Pecten maximus. Sterols were isolated by Silicagel 60 thin layer chromatography and identified by gas chromatography/mass spectrometry. Eleven sterols were identified, with cholesterol, brassicasterol, 24-methylenecholesterol and 22-trans-dehydrocholesterol being the principal components. The same sterols were found in all three tissues independent of se...

A feeding experiment was conducted to determine the minimum dietary zinc requirement of juvenile abalone, Haliotis discus hannai, with zinc methionine (ZnMet) and zinc sulfate (ZnSO4·7H2O) as the zinc sources and to compare the bioavailability of the two zinc sources using a premium quality diet based on casein–gelatin as the protein sources. Semipurified experimental diets containing graded levels of dietary zinc (5.6–84.6 mg zinc/kg) provided as either ZnMet or ZnSO4 were fed to juvenile abalo...

Abstract The effect of dietary cholesterol on growth, molting frequency and survival of juvenile mud crab, Scylla serrata was investigated using semi-purified diets. Six isoenergetic and isonitrogenous diets containing 0.04%, 0.21%, 0.50%, 0.79%, 1.12% and 1.44% supplemental cholesterol were evaluated. Fifteen mud crabs per treatment, with an initial mean weight of 84.4±30.9 mg, were individually housed in 3 l containers. After termination of the experiment, crabs fed the diets containing 0.5 an...

Oxygenated derivatives of cholesterol (oxysterols) present a remarkably diverse profile of biological activities, including effects on sphingolipid metabolism, platelet aggregation, apoptosis, and protein prenylation. The most notable oxysterol activities center around the regulation of cholesterol homeostasis, which appears to be controlled in part by a complex series of interactions of oxysterol ligands with various receptors, such as the oxysterol binding protein, the cellular nucleic acid bi...

Abstract The effect of lecithin and cholesterol on growth and survival of larval and postlarval Penaeus monodon was evaluated using semi-purified diets containing four levels of lecithin (0.0, 0.5, 1.0 and 1.5%) and three levels of cholesterol (0.0, 0.5 and 1.0%). Three early stages (zoeal, mysid and postlarval) of P. monodon were fed the experimental diets. Growth and survival of shrimp fed diets containing 1.0 and 1.5% lecithin were not significantly different (P>0.05) but these groups had sig...

ABSTRACT A 16-wk feeding trial was conducted to assess the effects of different types of dietary carbohydrate on growth and body composition of juvenile abalone (Haliotis discus). A total of 1,680 abalone were randomly distributed among 24 containers (70 per container) and fed one of eight diets, including seven experimental diets containing different types of carbohydrates, including dextrin (DT), glucose (GC), corn starch (CS), α-cellulose (CL), maltose (MT), sucrose (SC), and wheat flour (WF)...

Teleost fish, as with all vertebrates, are capable of synthesizing cholesterol and as such have no dietary requirement for it. Thus, limited research has addressed the potential effects of dietary cholesterol in fish, even if fish meal and fish oil are increasingly replaced by vegetable alternatives in modern aquafeeds, resulting in progressively reduced dietary cholesterol content. The objective of this study was to determine if dietary cholesterol fortification in a vegetable oil-based diet ca...

Consumption and digestibility rates of four food items (sea star: Luidia sarcii and Astropecten aranciacus, squid: Nototodarus sloanii, shrimp: Parapenaeus longirostris and fish: Boops boops) by the marine gastropod Charonia seguenzae were studied. The food with the greatest mean daily consumption in wet weight was the sea star with 24.03 ± 2.69 g, followed by fish (11.36 ± 3.74 g), shrimp (9.52 ± 1.21 g) and squid (7.36 ± 2.16 g). Absorption rate was higher when squid was consumed (97.1 ± 3.7%,...

Abstract A 16-week growth study was conducted to determine the dietary folic acid requirement of juvenile abalone (initial mean weight 482.2 ± 2.2 mg). Six semi-purified diets were formulated to contain graded levels of folic acid (0.06, 1.44, 2.86, 5.88, 14.27 and 35.71 mg/kg). Each diet was fed to three replicate tanks of abalone in a re-circulated water system. The results showed that the weight gain rate (WGR) was significantly increased when dietary folic acid contents increasing from 0.06 ...

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%...
