Depletion of wild fish populations puts US food security at risk. Supplementary methods of fish cultivation are in greater demand. Many fish farmers utilize floating raceways and have encountered difficulties in tracking and quantifying fish growth. This difficulty in monitoring fish growth made determining the health and growth rate of farmed fish challenging as it makes it harder for farmers to predict their profit. A device that can estimate fish biomass in floating raceways is in demand.

In the image, it shows the 3D model of the raceway being used in the project. In the middle is a transducer and a receiver, which is going to be used to measure the swim bladder size and the total biomass of the raceway.
