Cadmium (Cd), as one of heavy metals and an environmental stressor, may alter many physiological processes like growth and serum parameters in fish. The main objective of this study was to determine the effects of cadmium at sub-lethal concentrations (1 and 3 μg/l) on growth and serum biochemical parameters including enzymes, i.e. alkaline phosphatase (ALP), aspartate aminotransferase (AST) and...

This study investigated the effects of sudden weaning of angel fish larvae (Pteraphylum scalari) from Artemia nauplii to commercial larval feed. Four days post hatch (DPH) larvae were reared in four different weaning protocols (TR1-TR4) with triplicates in a complete randomize design. Larvae in TR1 and TR4 were exclusively fed Artemia nauplii and dry feed respectively. In TR2 and TR3, larvae we...

This study aimed to evaluate the impact of using insect-based fish feed on growth Ctenopharyngodon idella (grass carp). A meal in powder form was produced larvae blowflies. The mixture contained either 20% or 40% larvae, combined with conventional ingredients. fingerlings were divided into three groups and fed this formulated for 10 weeks, while ensuring that physio-chemical parameters within o...

We present preliminary iron abundances and α element (Ca, Mg) abundance ratios for a sample of 22 Red Giant Branch (RGB) Stars in the Sagittarius galaxy (Sgr), selected near the RGB-Tip. The sample is representative of the Sgr dominant population. The mean iron abundance is [Fe/H]=-0.49. The α element abundance ratios are slightly subsolar, in agreement with the results recently prensented by [...

The giant molecular cloud complex, Sagittarius B2 (Sgr B2), was observed with the ISO Long Wavelength Spectrometer over the range 47–197 μm. The ground state rotational transitions of OH lie in the survey range and we have analysed results from the OH, OH and OH isotopomers. Absorption in these lines due to clouds along the line of sight towards Sgr B2 has allowed us to compare the isotopomer a...

In order to investigate the effects of temperature on growth performance, biochemical indexes and genes expression in juvenile hybrid sturgeon (Acipenser baerii♀ × Acipenser schrenckii♂), five treatment groups (18 °C, 21 24 27 30 °C) were set this study. After 25 days domestication, specific rate (SGR) relative weight gain increased at first then decreased with increase range 18–30 °C reached h...

Abstract Palm oil mill effuent (POME) has the potential to become an environmental pollutant if left unutilized. This study aims examine effect of POME on catfish and water spinach growth in bucket fish culture system (budikdamber). research was conducted August-November 2021, comprises acclimatization fish, seeding, media preparation, rearing, observation, data analysis. used a completely rand...

Medicare's method to annually update the fees it pays physicians has been under fire for some time--specifically, since the method determined that physician fees should be reduced rather than increased. The update method, called the sustainable growth rate (SGR), was implemented to control the growth in Medicare physician spending. Yet Congress, in response to physician concerns about beneficia...
