Dynamic Light Scatter (DLS) aka "Speckle" techniques determine a histogram of particle sizes of solids suspended in sample water.

Laser (red taped) onto sample cuvette, observed by camera. Electronics pulses laser and collects images.
A sample of the aquaculture water is transferred into a sample cuvette, where it is illuminated by pulsed diode lasers to produce scattered light. A camera synchronized with the laser then views the scattered light and records the speckle images. These speckle pattern data are then processed to tell us of the range of particulate sizes suspended in the water, with 2um to 100um being of primary interest.

The computer processing will make use of training data taken from imaging sample sets whose suspended particle sizes are known from sequential particulate filtering, Coulter counting or from calibrated uniform size. See here.
