[Problem]

To provide an apparatus for sorting aquatic organisms according to characteristics thereof.

[Solution]

An apparatus (1) for sorting aquatic organisms having different characteristics in accordance with the characteristics, the apparatus including a container (10) configured to contain the aquatic organisms and water, a plurality of electrodes (20) provided in the container, a controller (30) for controlling electric pulses applied to one or more electrodes of the plurality of electrodes, and a driving-out unit (40a and 40b) for driving out the aquatic organisms having been sorted, wherein the electric pulses controlled by the controller are applied to the one or more electrodes to form an electric field so as to selectively move the aquatic organisms in the container to different portions (P1 and P2) in the container according to the characteristics, and the driving-out unit drives out the aquatic organisms to an outside of the container from the portion according to the characteristics, after the aquatic organisms are moved.

A computerized machine (a) determines temporal and spatial confidence intervals for each one of plural sonic events, (b) classifies pairings among the sonic events as either comparable or non-comparable, and (c) estimates a minimum number of sonic sources, some of which are in motion, that could have produced or generated the sonic events. Sonic event times and positions are characterized by corresponding temporal and spatial confidence intervals. A pairing of sonic events is classified as comparable only when that pairing meets one or more preselected constraints, some of which depend on the temporal and spatial confidence intervals. The estimated minimum number of sonic sources is equal to the total number of sonic events minus the cardinality of a maximum matching of a bipartite graph derived from the classifications of the pairings and a chronological ordering of the set of sonic events.
