Artêmia: otimização da taxa de eclosão por método químico

Abstract

The objective of this work was to evaluate the viability and takeoff of the art against four different pH solutions, altered with NaHCO3 and to evaluate the survival against these applications. To change the pH, NaHCO3 was used and used for each solution. The pH was altered with the aid of the digital phometer. An hatching rate was calculated for all controls. The experiment was analyzed in a randomized design in a 4x4x3 factorial scheme, four uses and three replications. Survival was calculated for each treatment. The toxicity test was analyzed in IHD in the 4x4x5 factorial scheme, four sessions and five repetitions. The control group shows hatching rates of 23%, generally all takeoff times, the highest hatching rates independent of exposure time and the pH of the solution. Art studies applied to the pH 6 solution calculate whether the exposure time is adequate for a linear equation, demonstrating the longer the exposure and the hatching rates. Exposure to pH 7 over time is adequate for a quadratic equation or reveals that this ideal solution is a maximum exposure of 15 minutes. For pH 8 and 9, despite low hatching rates or increasing solution exposure time, increased hatching rates. Conclude whether pH solutions can be used as descendants for the art. The exposure time of art arguments is correlated with a solution. Based on the results of this study, it is recommended to use pH 6 with 30min exposure time of art arguments. PH 9 has low survival rates, which shows the use of NaHCO3 in toxic for artifacts.
