 Environmental enrichment is one of the methods for improving fish growth performance. In the present trial, the effects of both light color and music on growth performance and survival of goldfish (Carassius auratus) (initial mean weight: 4.15±0.08 g) were investigated for 2 months. Two light color treatments (red light and white light) and three music treatments (M0: without music, M30:30 min...

The objective of this study was to investigate the growth rate of Chlorella vulgaris for CO2 biofixation and biomass production. Six mathematical growth models (Logistic, Gompertz, modified Gompertz, Baranyi, Morgan and Richards) were used to evaluate the biomass productivity in continuous processes and to predict the following parameters of cell growth: lag phase duration (λ), maximum specific...

Further understanding of the physiological states of Mycobacterium tuberculosis and other mycobacteria was sought through comparisons with the genomic properties and macromolecular compositions of Streptomyces coelicolor A3(2), grown at 30 degrees C, and Escherichia coli B/r, grown at 37 degrees C. A frame of reference was established based on quantitative relationships observed between specifi...

The present study was conducted to compare the growth indices and blood factors of sterlet (Acipenser ruthenus), Siberian sturgeon (Acipenser baerii) and their hybrid (Acipenser ruthenus ♀ × Acipenser baerii ♂) to produce a fish with larger size, larger eggs and more tolerant to environmental conditions than the parents. The hybrid was produced by mixing of the oocytes of one sterlet female wit...

We examine methods to estimate the average and variance of test error rates over a set of classi ers We begin with the process of drawing a classi er at random for each example Given validation data the average test error rate can be estimated as if validating a single classi er Given the test example inputs the variance can be computed exactly Next we consider the process of drawing a classi e...

Given a sequence of iid demands and an order up to replenishment policy with negligible lead time, we prove that average fill rate is monotonically decreasing in the number of periods in the planning horizon. This was conjectured to be true in a recent issue of this journal.

in this study, the effect of garlic extract on the growth performances ( body weight increase (bwi), specific growth rate (sgr), condition factor (cf), final length (fl) and weight (fw)), feed indices (feed conversion rate (fcr), protein efficiency ratio (per), protein production ratio (ppr)) and body composition (protein, fat, moisture and ash) of mugil cephalus larvae were studied in four tre...
