Freshwater Colloquium: Harvest, Starvation and Recovery of Nitrification in an Aquaculture System

Carmen Aguilar and Russell Cuhel will present the Freshwater Colloquium “Harvest, Starvation, and Recovery of Nitrification in a 15,000-fish Freshwater Yellow Perch Recirculating Aquaculture System” as part of the School of Freshwater Sciences spring colloquium. The theme of this semester’s colloquium is Trends in Aquaculture: Meeting the Challenge of Feeding a Changing World.

This presentation is open to the public. Join via Zoom at https://wisconsin-edu.zoom.us/j/96925684483?pwd=LzRXVWZHQkg5cVFIOWN1QlVoV1l3UT09

Aguilar and Cuhel are senior scientists in the UWM School of Freshwater Sciences. In Recirculating Aquaculture Systems (RAS) of any salinity, biofilters are the core of success or failure in maintaining delightful water chemistry for encouraging animal product growth, whether fish or invertebrates. Because of large scale required for commercial applications, a substantial amount of inertia is assumed to protect against episodic events. It is also believed that resilience is large and recovery from incidents is rapid. This presentation tests those assumptions quantitatively for a fully-stocked yellow perch operation during and following harvest of a full load of 15,000 market-sized perch.
