Recirculating Aquaculture Systems Course

The 2025 Course is scheduled for the week of August 18-21 in Shepherdstown, WV and will cover a range of topics from RAS fundamentals to fish health and biosecurity, system operations and maintenance, AI technology and more.

Introduction

This four-day course on water recirculating aquaculture systems started in 1995 at Cornell University in cooperation with Freshwater Institute staff.

The course was initially held at Cornell University, but in 1999 it was moved to the Freshwater Institute as a combined Cornell University/Freshwater Institute course. The combined course continued through 2006, after which the course was taught independently by both institutions until Cornell University stopped offering a classroom course. Course participation has expanded from university extension associates to currently include representatives from commercial fish farms, government fish hatcheries, tribal fish hatcheries, universities, research organizations, and fish and wildlife organizations. Current course content covers the fundamentals of water recirculating systems for fish culture including unit processes, fish health and biosecurity, system operations and maintenance and water quality monitoring. In 2024 we added modules covering emergency response, AI technology, finishing and harvesting and troubleshooting.

  • RAS Overview
