Several authors have previously demonstrated that the number of skin mucous cells fish is affected by many stressors. In present study, two experiments were conducted in order to examine effects common environmental conditions on morphology sea bass and particularly diameter cells. first experiment, groups (mean weight 155.6 +/- 10.3 g SD) maintained different concentrations nitrate, 100 700 ppm respectively, for 48 h, while a third group was used as control. second (initial mean 78.9 3.1...
The aim of this study was to investigate the effects fasting on certain quality parameters commercial size gilthead sea bream (Sparus aurata) with different dietary history. Three groups (× two replicates) were distributed into six cages and fed ad libitum by demand feeders for 4 months feeds containing protein–fat percentages (38 : 20, 45 15, 51 10). fish submitted a subsequent 3 weeks. They all showed similar mobilization patterns an initial hepatosomatic index reduction (indicating liver...
Two growth trials were conducted to evaluate the nutritional quality of several soybean products as constituents in diets for gilthead sea bream, Sparus aurata (L.). In a preliminary experiment, fish fed six containing different levels solvent extracted meal replacement white fishmeal at four substitution levels: 10, 20, 30 and 40% protein component. The supported less inclusion increased. However, significant reductions apparent 30% level. All parameters followed same trend. second with 35%...
The effects of steam pelleting or extrusion a commercial feed on performance 2 g (small) and 40 (large) gilthead sea bream was studied. In addition the apparent digestibility diets, gastric evacuation time (GET) trypsin amylase activities were measured in large fish. Fish size significantly increased protein energy productive value, body lipid, liver glycogen however decreased daily growth index, intake utilization, moisture hepatosomatic index. Extrusion processing intake, more strongly for...
The dietary lysine requirement of juvenile gilthead seabream was determined by the growth response duplicate groups fish (3.5 g initial weight) fed on six isonitrogenous (427 kg−1) and isolipidic (135 diets containing graded levels crystalline l-lysine HCl, with content ranging from 36.3 to 79.7 kg−1 protein. final indispensable amino acid profile except for formulated so as resemble that wild whole body. Except reduced performance lysine-deficient no other deficiency signs were apparent....
Fish processing creates a large amount of waste high nutrient content which, if not properly processed for use in human or animal nutrition, is likely to be deposited the environment creating pollution problems. Waste parts from rainbow trout smoking, consisting heads, bones, tails and intestines, were used as feed ingredients gilthead bream diets. Heads, bones had similar compositions, their weighed mean indicating about 700 g kg−1 moisture, 150 protein 110 fat. Intestines contained higher...
The immune response of European sea bass, Dicentrarchus labrax, to a natural infection by the copepod parasite Lernanthropus kroyeri was evaluated for first time in vivo. results clearly demonstrated triggering fish system parasite. Lysozyme activity and alternative complement pathway were involved early action against parasitical infection, whilst classical respiratory burst (RB) took over later stages infection. It hypothesized that levels RB stimulation indexes may determine resistance...
The leaching of oxolinic acid (OA) and oxytetracycline (OTC) from medicated feeds, as well the palatability digestibility these drugs were investigated in seabass Dicentrarchus labrax L. (350 g) at 16 °C 24 water temperature. Oil-coated OA OTC on feeds greatly affected by (losses 55.5% 42.5% for respectively) (32% 47% OTC). However, a significant reduction drug loss resulting was evident when antibiotics mixed with diet (5% 6.5% OTC) (10% 20% respectively). Increased temperature induced...
The pharmacokinetics and tissue distribution of oxolinic acid following an intravascular administration (15 mg kg−1 fish) were determined in sea bass, Dicentrarchus labrax L. (110 g), at 13 °C 22 water temperature. kinetic profile the drug was found to be temperature dependent, with increased having a greater effect on after equilibrium elimination phase than process. distibution half-life 1.15 2.76 h respectively, whereas 55 315 °C. values apparent volume (1.44 L 3.31 °C) steady state (5.2...
