ABSTRACT:
The present invention is a method and apparatus for counting discrete small objects suspended in a liquid stream. It comprises a source of flowing liquid having sufficient known velocity to maintain the objects in suspension, a means for introducing the objects into the liquid stream, and a calibrated turbidity measuring device. The outflow may be automatically shifted from one receiving means to another when a predetermined object count is reached. The method is particularly useful when counting living objects, such as fish fry or post-larval shrimp, since it eliminates the trauma of handling and is much faster than hand counting.
