Abstract
Objetive. Realize an experimental cuculture of cladorerans Moina sp feed with Ankistrodesmus sp and Saccharomyces cereviseae. Materials and methods. At Universidad de Córdoba, Laboratory of Food Live, experimental cultivations of the cladocerans stump Moina sp under controlled conditions of temperature (22°C), pH (7.6), light intensity (2000 lux) and air condition were made. Two food diets were used as treatments (Ankistrodesmus and Ankistrodesmus + Saccharomyces. cereviseae) in concentration of 40 x 105 cel.ml-1, to determine their effect on the population’s acting. Populational and celular density were registered daily. Results. The results showed significant difference for the effect of the diets on the populational growth of the cladocerans, the individuals fed with Ankistrodesmus sp + Saccharomyces cereviseae reaches density of 12.3a ±0.30 org/ml-1 presenting highest instantaneous rate of growth (K) 0.36 ± 0.002, the smallest time of duplication (td) 1.94 ± 0.012 and the highest yield (r) 1,1 ± 0.07 clad.ml-1.day-1. Conclusions. These cladocerans for their characteristics of growth in cultivation, present favorable adaptation to the handling conditions to produce biomasses potentially useful as nutritious particle with aquaculture purposes.
