Effect of saffron petal powder on feed, growth performance and antioxidant enzymes activity of grass carp (Ctenopharyngodon idella)
Authors
Abstract:
The present study was conducted to determine the effect of saffron petal powder on the growth and activity of antioxidant enzymes in the grass carp larva (Ctenopharyngodon idella). Fish larva (0.75 ± 0.03 g and 4.39± 0.09 cm) were fed separately with four levels of saffron petal powder diets which were included; P0 (0%), P1 (2%), P2 (4%) and P3 (6%) for 60 days. One thousand two hundred fish were divided randomly into 12 tanks (4 experimental treatments and each with 3 replications). End of the experiment, growth (final weight, final length, daily growth rate, weight gain, specific growth rate and condition factor), feed (food conversion ratio and food conversion efficiency) and Antioxidant (glutathione peroxidase, superoxide dismutase, malonyldialdehyde and catalase) parameters were evaluated. Growth parameters were enhanced following feeding with saffron petal powder compared with the control group. The final weight and specific growth rate in P2 treatment increased significantly compared to control, while there was a significant reduction in food conversion ratio (FCR) in this treatment. In addition, the activities of MDA and Catalase were significantly decreased in the fish larvae fed with different levels of supplement compared to those of the control group. A significant enhancement in the SOD and GPX parameters of P3 compared to control. This research demonstrated that the saffron petal powder of 6% could be used as a promising feed additive in aquaculture.

Effect of Dietary Energy to Protein Ratios on Growth Performance and Feed Efficiency of Juvenile Grass Carp (Ctenopharyngodon idella)
A feeding trial of three dietary protein (DP) (25, 35 and 45%) and four dietary lipid (DL) levels (3, 6, 9 and 12%) with different dietary energy to protein (E/P) ratios (from 5.93 to 13.84 kcal/g protein) was conducted to investigate the proper dietary E/P ratio for juvenile grass carp. After acclimation of 2 weeks by a lipid-free diet, fish were reared for 10 weeks in a water recirculation sy...

In present study the effect of feeding frequency on growth performance, feed efficiency and survival rate of juvenile of grass carp were investigated. Three groups of juvenile grass carp (average weight 4.31±0.1 g) designed with three feeding frequencies one meal a day (D1), two meals a day (D2) and four meals a day (D3) with two replicates of each treatment combination were applied in this exp...

The grass carp (Ctenopharyngodon idella) is a herbivorous, freshwater fish species of the family Cyprinidae, and the only species of the genus Ctenopharyngodon. Neoplasms in fishes are generally less aggressive than neoplasms in mammals and are most commonly discrete, focal and benign neoplasms. A 3-year-old grass carp with a big mass on the vertebrae was referred to the clinic. According to the...

OBJECTIVES The aim of present study was to evaluate the effect of peracetic acid (PAA) on haematotological and biochemical indices, antioxidant status, micronucleus induction and histopathological alterations of liver and gill in grass carp. METHODS Grass carp (Ctenopharyngodon idella) juveniles were exposed to therapeutic concentrations (1, and 3 mg x l(-1)) of PAA for a period of 10 days. S...

BACKGROUND Myxovirus resistance (Mx) proteins are crucial effectors of the innate antiviral response against a wide range of viruses, mediated by the type I interferon (IFN-I) signaling pathway. However, the antiviral activity of Mx proteins is diverse and complicated in different species. METHODOLOGY/PRINCIPAL FINDINGS In the current study, two novel Mx genes (CiMx1 and CiMx3) were identifie...

Global fish production from aquaculture has rapidly grown over the past decades, and grass carp shares the largest portion. However, hemorrhagic disease caused by grass carp reovirus (GCRV) results in tremendous loss of grass carp (Ctenopharyngodon idella) industry. During the past years, development of molecular biology and cellular biology technologies has promoted significant advances in the...
