The main characteristics of a wide photometric survey of the Sgr dwarf spheroidal galaxy are shortly presented. V and I photometry has been obtained for ∼ 90000 stars toward Sgr and for ∼ 9000 stars in a region devoid of Sgr stars (for decontamination purposes). The full potential of this large database is far from being completely explored. Here we present only preliminary results from the ana...
The conventional assessment of the specific growth rate (SGR) avoiding intermediary data is highly criticized by scholars as to beginning and end production cycle usually considered for measurement. To evaluate SGR, study was conducted in six concrete tanks under an outdoor laboratory shed from 10th May 29th July 2017. Tilapia (Oreochromis niloticus) fry released at 8 fries per tank recommended...
In this study, two main probiotics (Lactobacillus plantarum and Lactobacillus delbrueckii subsp. bulgaricus) were isolated from the intestine of Tor grypus and their effects on growth performance, gut microbial flora and digestive enzymes activities (i.e., α-amylase, lipase, trypsin, chymotrypsin, and alkaline phosphatase) of Tor grypus (Karaman, 1971) were determined. Juveniles of T. grypus (n...
The recirculating aquaculture system (RAS) is a cultivation that minimizes water changes and can optimize high stocking densities (SD). purpose of this study was to determine the effect nursery culture in density with RAS on survival rate (SR), specific growth (SGR), relative length (LR), weight gain (WG), (LG)and feed utility efficiency (FUE) juvenile catfish. used completely randomized design...
This study was conducted with different levels (0, 0.25, 0.5,1,2 g) of Zingiber officinale powder per 100 g of common carp commercial diet. Feed was offered for 8 weeks by the post pelleting liquid spraying method. Results showed that there were significant differences in all growth parameters and body composition except in survival rate, Gain Weight Percent (GW%) ,SGR and NFE between treatment...
The present experiment evaluated the effects of fat (Kilka fish oil) levels (0, 5, 10, 15 and 20%) in the diet (35% constant protein) on performance of rainbow trout. The experiment was performed in a completely randomized design, with 4 replicates, 200 grower fish with an average weight of 200±11 gr, each. They were randomly divided into 20 groups of 10 fish per group reared in separate pens. ...
Plant proteins are plausible fishmeal substitutes but are deficient in some essential amino acids (EAA) like lysine and methionine. Combination of different plant proteins with complimentary EAA could be useful alternative. Bambaranut (Voandzeia subterranea) contains high amount of lysine while methionine is in sesame seed (Sesamum indicum). This experiment tested effects of combining sesame se...
Evaluating the effect of dietary soybean oil (S.O) on growth performances of juvenile ornamental fish Severum (Heros severus) was the main objective of this study. To achieve this objective, 462 fish were considered which were divided into 7 test groups including 6 groups of fishes (with an initial average weight of 0.6 ± 0.05 g and length of 2.3±0.35 cm) fed diets containing 6 levels of S.O (D...
To determine the effects of dietary organic selenium (OS) supplementation on the growth performance and immune competence of marron, Cherax cainii (Austin, 2002), a group of marron were fed 0.2 g kg(-1) of Sel-Plex(®) supplemented basal diet and then compared with another group (control) of marron fed basal diet without any supplementation. After 90 days of feeding, final weight, average weekly...
This experiment was conducted to evaluate the effects of different carbohydrate levels on growth performance, glycogen accumulation in tissue, enzyme activities, and expression genes related hepatopancreatic glucose lipid metabolism insulin signaling pathway swimming crab, Portunus trituberculatus for 8 weeks. The results indicated that crabs fed with 60.0 g kg-1 diet exhibited highest final bo...
