Dynamic Fish Manure Extractor System

Cleanliness in fish hatchery raceways is of the utmost importance when it comes to healthy fish. As an engineering team, our purpose is to design a system that can effectively reduce the build-up of fish manure on the bottom of the raceways without causing re-suspension of the manure in the water.

Previous Designs

 * A screen that is pushed across the bottom of the raceways to collect manure
 * A vacuum that cleans waste in the quiescent zone
