Exploring recirculating aquaculture systems
Abstract: Recirculating Aquaculture Systems are becoming prevalent in the US aquaculture industry, and there are numerous advantages and disadvantages (from environmental, economical, and marketing perspectives) for using these systems. In order to be efficient, careful planning goes into the design engineering to achieve satisfactory and sustainable production levels. In this lesson, students will explore an RAS computer tutorial and navigate to examine content summarizing RAS components and descriptions. There is a digital self-test within the RAS computer tutorial to assess understanding of system components and their functions.
Students will be able to launch the RAS digital model and explore by manipulating variables (e.g., stocking densities, filtration efficiencies, feeding rates, temperature, etc.) and observing model simulation results. Through the use of this model, students will become knowledgeable about the utility of recirculating aquaculture systems (RAS) for aquaculture production, their advantages and disadvantages relative to cost, production efficiency and yield, and level of complexity. Students will be able to identify system components, their function within the integrated system, and their appropriate installation and maintenance.
