Hatching of brine shrimp eggs (Artemia franciscana Kellogg) in the laboratory of Universidad Nacional Agraria, Managua, Nicaragua

Abstract

In the study of hatching of Artemia franciscana at laboratory level, aimed to determine the type of treatment that fits laboratory conditions giving good results for hatching the brine shrimp, Artemia (Artemia franciscana Kellogg). The methodology consisted of data collection in the laboratory evaluated by the following treatments: Taking pH; Taking temperature; Salinity; Survivorship measurement. Once established the study proceeded to put the egg of Artemia, which began to hatch iu 48 hours to start the process eclosivo crustacean. Management that was applied in the study consisted of taking data of temperature and pH to track and monitor the hatching of Artemia and control feed consisting base diet pill alga Spirulina maxima crushed. According to statistical analysis using methodology DUNCAN, Pearson correlation and processed in the INFOSTAT statistical program indicate that the best hatching was recorded in treatment D with 65.40% giving guidelines to be the treatment best adapted to the conditions of laboratory. The survival of other treatments is positive and adaptable to laboratory conditions where it is advisable to use containers with larger capacity water storage. It is recommended for future crops Artemia can carry out the management and implemented in the Laboratory of Biological Sciences of the National Agricultural University for higher performance in the survival of the study, and continue to provide information to the emergence of this crustacean food option for the low impact fishing producers in the country.
