Key word: Growth promoter, mono-sex Tilapia, production, probiotic, FCR, SGR The present study was conducted in farmer’s ponds at field level of Muktagachha upazilla to find out the effect of growth promoter on growth performance and feed utilization of monosex Tilapia fish. Growth promoter was used in the experimental cultured farm. This growth enhancing aqua drugs was used in feeds of Tilapia...

This study was conducted to evaluate the effects of dietary levels of vitamins E (25, 30 and 35 mg kg-1), Folic Acid (1.5, 2 and 2.5 mg kg-1) and their combination on the growth performance, hematological and immunological parameters of rainbow trout, Oncorhynchus mykiss. Each diet was fed to rainbow trout in triplicate to apparent satiation four times daily for 8 weeks. At the end of the feedi...

An 11-week feeding trial was conducted to assess the dietary lysine requirement for juvenile Hemibagrus wyckioides. Six isoproteic and isoenergetic diets (41.66% crude protein, 20.56 kJ/g gross energy) containing 1.1%, 1.5%, 1.9%, 2.3%, 2.7%, 3.1% were prepared feed juveniles (average initial body weights of 1.25 g), respectively. The weight gain, specific growth rate (SGR), conversion ratio (F...

With the general objective of optimizing internal nutrient recycling, circular multitrophic food production systems, e.g., combining fish, plant, and insect larvae production, rely on quality composition sustainable nutritional inputs. Therefore, differences in dissolved solid excretion patterns produced by Nile tilapia (Oreochromis niloticus) reared recirculating aquaculture systems (RAS) with...

We report IRAM 30-m observations of DCN and DCO+ towards the galactic center molecular clouds Sgr B2 and Sgr A. We compare our results with simultaneous measurements of H13CN and HCO+ in order to derive estimates of the [DCN]/[HCN] and [DCO+]/[HCO] abundance ratios. We mapped Sgr B2 in DCN(2-1) and DCN(3-2) and we compared HCN with DCN for one position of our maps. The uncertainties in such mea...

an 84-day feeding trial was carried out onfingerling (4.44 ± 0.06 g) rainbow trout (oncorhynchusmykiss, walbaum, 1792) to evaluate the effect of dietary supplementation with a commercial prebiotic grobiotic®-a (g-a) on the growth, feed efficiency, haematology and immunlogical parameters. ttreatments containing various inclusions of g-a (0 %, 0.5 %, 1.0 %, 1.5 %, 2.0 %, 2.5 %, and 3.0 %) were ad...

This study aims to determine the effect of amphipod density on growth, survival and molting mangrove crabs (Scylla tranquebarica).The research was conducted in Installation Tiger Shrimp Hatchery (ITSH), located Lawallu Village, Soppeng Riaja District, Barru Regency, South Sulawesi, from May June 2022. There 45 crabs, with an average weight 0.04 ± 0.005 g a carapace width 5.4 0.1 mm which were o...

We report the diffuse X-ray emissions from the Sgr A and B regions observed with Suzaku. From the Sgr A region, we found many K-shell transition lines of iron and nickel. The brightest are Kα lines from FeI, FeXXV and FeXXVI at 6.4 keV, 6.7 keV and 6.9 keV. In addition, Kα lines of NiI and NiXXVII, Kβ of FeI, FeXXV and FeXXVI, and Kγ of FeXXV and FeXXVI are detected for the first time. The cent...
