This study was conducted to investigate the effects of sublethal phosalone concentrations on the hematological, serum biochemical, and immunological responses of carp (Cyprinus carpio). The fish were semi-statically exposed to low (0.15 mg/L), medium (0.3 mg/L), and high (0.6 mg/L) phosalone concentrations for 14 days. Results showed that the hematological(More)
This study was conducted to investigate the effects of garlic and ginger oils on hematological and biochemical health characteristics of sea bass Dicentrarchus labrax. Fish were exposed to garlic oil (0.01 or 0.02 mL/L), ginger oil (0.01 or 0.02 mL/L), or a combination of the two oils (each oil at a concentration of 0.005 or 0.01 mL/L) for 96 h via bath(More)
In this study, possible oxidative stress, biomarkers, and histopathological alterations were investigated in common carp (Cyprinus carpio, L., 1758) that were exposed to various phosalone concentrations in vivo. Fish were exposed to 0.15, 0.3, and 0.6 mg/L phosalone concentrations in a semistatic regime for 14 d. Biomarkers, including Na(+), K(+)-ATPase,(More)
The present study investigated the effects of dietary thyme, rosemary and fenugreek supplementation on welfare status of sea bass, Dicentrarchus labrax L. assessed by blood parameters. Three experimental diets were supplemented with 1 % of the different spices. After 45 days of the feeding trial, the spices did not significantly affect the erythrocyte(More)
The objective of this study is to investigate the effects of dietary protein and lipid levels on the growth performance and bioeconomic benefits of two-banded seabream (Diplodus vulgaris) juveniles, a candidate species for aquaculture sector. Eight experimental diets were formulated with four protein (50, 45, 40 and 35 %) levels for each of the two lipid(More)
Tilapia (Oreochromis niloticus) was exposed to different sizes of zinc oxide nanoparticles (ZnO-NPs) to evaluate their organ pathologies (kidney, liver, gill, and intestine), osmoregulatory responses and immunological parameters. Sub-chronic exposure was conducted in fresh water with 1 and 10 mg/L concentrations of the small (10-30 nm) and large-size ZnO(More)
Oreochromis mossambicus were exposed to two different temperature and carbon dioxide partial pressure levels for about two weeks, as the ambient (Control; 25°C, 3.3mg/L CO2), high CO2 (25°C, 14mg/L CO2), high temperature (30°C, 3mg/L CO2) and combined (30°C, 14.1mg/L CO2) groups. No mortality was observed during the experiments. As a result of the study,(More)
Abstract Allspice Pimenta dioica as a feed additive was studied for its effects on growth performance and disease resistance in Mozambique Tilapia Oreochromis mossambicus. Five isonitrogenous (36% crude protein) and isocaloric (18.5 kJ/g) diets were formulated to contain 0 (control), 5, 10, 15, or 20 g of allspice/kg of fish feed. In a 50-d feeding trial,(More)
Zinc nanoparticles (ZnNPs) are among the least investigated NPs and thus their toxicological effects are not known. In this study, tilapia (Oreochromis niloticus) were exposed to 1 and 10 mg/L suspensions of small size (SS, 40-60 nm) and large size (LS, 80-100 nm) ZnNPs for 14 days under semi-static conditions. Total Zn levels in the intestine, liver,(More)
Article info: Received: 1 March 2013 Accepted: 29 November 2013 ABSTRACT Phytoadditives have gained increasing interest as feed additives for fish. The aim of the present study was to determine whether selected dietary phytoadditive can influence the bioavailability of several trace elements (Cu, Mn and Zn), which play an important role in the physiological(More)
