Abstract

Experimental results from a culture of a microcrustacean, Daphnia obtusa Kurz emend. Scourfleld (Cladocerans), are presented. The experiments have been realized at an aquaculture farm using the thermal discharge of a thermoelectic power plant, in tanks whose volume was suitable for a production of biomass consistent with the needs of a small size fry farm.
Two different feeding combinations have been supplied with standard concentrations of algal cells integrated by cellulose and organic fertilizer respectively.
Numerical production from data of population density has been used to determine the relative efficiencies of the different feeding combinations, while the remaining estimated population parameters have been reserved to characterize the density fluctuations of the population.
