Sex-specific compensatory growth in food-deprived Nile tilapia
(Associação Brasileira de Divulgação Científica (ABRADIC), 2003-04-01)
Female Nile tilapia incubate fertilized eggs in their mouth until they are released as alevins. Consequently, the female may not eat during this period. Thus, it would be expected that female Nile tilapia are more adapted ...
Feeding level and frequency for freshwater angelfish
(Sociedade Brasileira de Zootecnia, 2012-06-01)
The objective of this study was to determine the optimal feeding level and feeding frequency for the culture of freshwater angelfish (Pterophyllum scalare). A randomized block design in a factorial scheme (3 × 2) with three ...
Longer wavelengths of light improve the growth, intake and feed efficiency of individually reared juvenile pikeperch Sander lucioperca (L.)
(Wiley-Blackwell Publishing, Inc, 2009-05-22)
We tested the effects of monochromatic light on the specific growth rate (SGR), feed intake and feed efficiency (FE) of juvenile pikeperch, Sander lucioperca (L.). Pikeperch were reared individually for 42 days in aquaria ...
Allometric scaling of biological rhythms in mammals
(Sociedad de Biología de Chile, 2005)
A demographic headwind: Will an aging society reduce the real interest rate and potential growth?
(Elsevier B.V., 2020-10-01)
Is secular stagnation a necessary result of population aging? This paper argues that demographic change itself is not enough to generate both slower economic growth and a lower real interest rate in an endogenous growth ...
Calculating effective growth rate from a random Leslie model: Application to incidental mortality analysis
(Elsevier Science, 2013-02-21)
Demographic models are commonly used to study cetacean population dynamics and are characterized by a wide range of age classes. The primary building blocks are age-specific survival or mortality and birth rates, which can ...
Comments on the calculation of the specific growth rate in experiments with untagged individuals
(Instituto de Ciencias del Mar Barcelona, 2015-11)
The specific growth rate, G, is widely used in articles dealing with the growth of aquatic organisms under experimental conditions. When individuals are untagged, the arithmetic mean of G for a group of animals must be ...
Screening for yeast with antibacterial properties from an ethanol distillery
(2004-03-01)
A general screening for the expression of antibacterial activity and non-flocculating type of yeast strains from must and fermented broth of alcohol distilleries was performed. From 60 strains only Saccharomyces sp. M26 ...
