    Resumen

    The theoretical basis underlying estimation of krill abundance using echo-integration and aggregation information are briefly described. The chief differences of the two approaches are highlighted. It is concluded that the echo-integration approach is superior for the estimation of regional krill abundance and its variance since it is easier to apply, requires less data analysis and does not necessitate any assumptions concerning aggregation distribution or conformation.
