Long-term effects of different concentrations of vinasse on growth and survival, reproductive and life span characteristics of Artemia franciscana (Kellogg, 1906) and Artemia parthenogenetica

The larviculture of fish and shellfish is inevitably dependent on live feed such as Artemia, and one of the most critical issues in rearing Artemia is the food supply. Artemia franciscana and Artemia parthenogenetica were raised at two concentrations of vinasse (62.5 and 125 mu l L-1). The control diet was algae + wheat bran. The results demonstrated significant differences in the survival of Artemia species grown in different concentrations of vinasse on diets (P < .05). However, no significant differences were observed in the length of 125 mu l L-1 and 20% algae with the A. franciscana control (P > .05). The total length in A. parthenogenetica was significantly higher than those received in vinasse (P < .05). The percentage of encysted in A. franciscana and A. parthenogenetica that fed vinasse in any concentration showed significant differences (P < .05) but not for other reproductive and lifespan characteristics (P > .05).
