INFLOW: Aquatic Animal Life Support Systems and Habitats, hosts Joe Arlotto and Dr. Jeff Keaffaber talk with Amy Stone, a designer whose career bridges aquaculture, aquaponics, and life support system design. Amy shares her journey from raising fish to leading Aquatic Equipment & Design.

This episode from Aquatic Equipment & Design Inc. provides general instructions for acclimating fish to a new tank environment over a period of 30 to 45 minutes, reducing stress from changes in water temperature and water chemistry. Methods emphasize the gradual introduction of the new tank water to the transport water and emphasize the importance of monitoring the fish's behavior for signs of distress.  

This episode explains what protein fractionation is and why it is important in the operation and management of recirculating aquaculture systems. Protein fractionation utilizes foam separation technology to remove fine suspended solids, dissolved organics, and pathogens by introducing air to create bubbles that absorb and carry surfactants to the water surface where it is concentrated, collected, and then drained out of the production system.  

This episode introduces the listener to practical calculations for determining the number of seeds to plant, accounting for germination rates and seedling viability, as well as the quantity of propagation trays and the total area needed for a staggered weekly production cycle. Additionally, it offers valuable tips for proper seed storage to maintain quality and ideal germination rates. Visit Aquatic Equipment & Design, Inc. at www.aquaticed.com for more.

This episode from Aquatic Equipment & Design Inc. focuses on the Feed Conversion Ratio (FCR) in aquaculture, explaining how it is calculated and its significance for fish farmers. It highlights FCR as a critical metric for measuring how efficiently fish convert feed into harvestable biomass which directly impacts operational costs and profitability.

This episode from Aquatic Equipment & Design Inc. explains the importance of cleaning aeration diffusers to maintain optimal oxygen transfer rates. A cleaning procedure using muriatic acid is presented as a simple management strategy to improve oxygen transfer efficiency, prolong the lifespan of the aeration system, and maintain the health of your aquatic species.

This episode from Aquatic Equipment & Design Inc. discusses a procedure to measure un-ionized ammonia in aquatic systems. It explains that while most ammonia is non-toxic, un-ionized ammonia (NH3) is highly toxic to aquatic organisms and its concentration is influenced by pH and temperature. It also offers corrective actions for managing high un-ionized ammonia concentrations. Visit Aquatic Equipment & Design, Inc. at www.aquaticed.com for more.

This episode from Aquatic Equipment & Design, Inc. outlines the process of performing dilutions for water quality testing to handle water quality parameters that exceed a test kit's detection limits. Topics discussed include dilutions with distilled water, providing clear instructions for calculating dilution factors, and then the reverse dilution to find the original concentration.

This episode from Aquatic Equipment & Design Inc. discusses the critical role of substrates in aquaponic transplant production. It emphasizes that selecting the correct substrate is vital for plant health, outlining the important physical and chemical parameters such substrates must possess, such as porosity, water retention, pH, and electrical conductivity.
