artemia plays a major role in aquaculture as one of the most important live foods used in larval rearing. the aim of this study was to determine the optimum level of feeding in artemia urmiana with baker's yeast (saccharomyces cerevisiae). triplicate groups were fed with different levels of s. cerevisiae yeast 0.625 (control), 1.25 (t1), 2.50 (t2), 5.0 (t3) (mg yeast per 1000 nauplii) for ...

The study evaluated the effects of Levamisole, Quil-A and Cinnamon on growth, hematological and immune parameters of marmalade cichlid. Fish (2.00 ± 0.02 g) were fed diets supplemented with 0.2% Levamisole, 0.5% Quil-A and 1% Cinnamon for 60 days and the control group was fed with basal diet. The highest weight gain and condition factor were observed in fish fed diet enriched with Levami...

This study examined the growth response of yellowfin seabream, Acanthopagrus arabicus, reared in floating net cage fed at variable daily feeding frequencies. Thirty healthy fish (49.7±0.3 g initial weight) were stocked in each of the 12 net cages (1.5×1.5×1.5m). Three cages in each group were assigned to four different feeding frequency i.e., two, three, four and six times/day designated as FF1...

The effect of feed supplemented with L-camitine at four levels of 0, 300, 600 and 900mg kg-1 on growth performance and body composition of beluga, H. huso, juveniles was evaluate din two separate trials. In the first trial, 180 juveniles (525±9gw) were fed with the test diet for a period of 71 days, and the trial extended to another 126 days in the second phase by randomly selecting 120 ...

in order to estimate responses of growth rate and growth hormone of clarias gariepinus to stocking density, fish (initial weight 30.71 ± 0.89 g) were stocked in 120-l tanks at densities of 35, 65, 95, and 125 kg/m3 for 60 days. on day 30 and 60, the fish growth rates were measured, pituitary growth hormone (gh) mrna levels and serum gh concentrations were examined by real-time qpcr and elisa te...

We used a selection of Arabidopsis thaliana mutants with knockouts in defence genes to demonstrate growth costs of trichome development and glucosinolate production. Four of the seven defence mutants had significantly higher size-standardized growth rates (SGRs) than the wild-type in early life, although this benefit declined as plants grew larger. SGR is known to be a good predictor of success...

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...

An initial experimental study was conducted to evaluate the effects of binaural beats on fish growth performance. A 90-day trial with four triplicate groups was conducted with 240 zebrafish, Danio rerio, under aquarium conditions. Binaural beat file complexes were played for each aquarium using computer controlled directional speakers for 0 min d-1(Control), 90 min d-1(Group 1), 180 min d-1 (Gr...
