ABSTRACT. Current study evaluates the macrophyte biomass of water hyacinth, Eichhornia crassipes, in diet food to improve the growth and survival of angelfish, Pterophyllum scalare. The liquid (extract) and ground modes ...

Nothofagus macrocarpa forests are situated in the northern limit of Nothofagus genus distribution in South America. Data related to their growth conditions are insufficient. Above-ground biomass accumulation and growth ...

Grasslands are the main source of feed for cattle in Argentina. Standing dead biomass accumulation threatens efficient resource use. The effect and timing of high impact grazing by cattle as a management tool to remove ...

The on-line estimation of non-measurable substances and key process variables is relevant for the real-time monitoring of the bioprocesses. This paper deals with the on-line estimation of microbial growth rate and biomass ...

An experiment was carried out at Sâo Manuel Experimental Farm, FCA-UNESP, Botucatu-SP, in 1994 and 1995, aiming to determine the biomass production and essential oil yield of mentrasto (Ageratum conyzoides L. - Asteraceae) ...

A dynamic biomass growth model for the mussel Mytilus chilensis in longline culture systems in proposed. This model determines the biomass by estimating the average weight and the number of mussels per meter of seeded rope, ...

Near-surface distribution (10 – 40 m depth), abundance, and biomass of small pelagic fish were estimated with an echo sounder (EY-60, 120 kHz) duringJanuary 2007 in central and northern areas of the Gulf of California. ...
