Factors To Consider To Maximize Your Regenerative Blower’s Efficiency and Life-Span

Regenerative blowers are essential tools for maintaining oxygen levels in aquatic environments. They must be correctly sized to overcome resistance from water depth and plumbing friction. Operators should prioritize placing blowers in cool, dry, and elevated locations with adequate ventilation to prevent motor overheating. It is also critical to manage back pressure by using appropriately sized pipes and installing heat-dissipating metal outlets to protect downstream PVC components. 

General Techniques and Practices for Feeding Fish Grown in Aquaculture

This episode provides an overview of fish feeding practices in aquaculture and how various factors influence feeding choices, such as fish life stage, water temperature, and the characteristics of the culture system. The discussion covers different feeding techniques, including relying on empirically developed feeding schedules, the subjective method of feeding to "apparent satiation," and the use of automatic and demand feeders to manage feed quantity and frequency.

Importance Of Calibrating Small Hand Pump Sprayers At Your Facility

This episode details the essential process of calibrating a one-gallon hand pump sprayer to ensure the accurate application of pesticides, fertilizers, and cleaners at your facility. It emphasizes the importance of safety and equipment maintenance, instructing users to wear protective gear and perform initial tests using only water. The resource provides a simple mathematical formula to help small-scale farmers scale their spray requirements to any size growing area.

What Is The Purpose of a Quarantine System

This episode emphasizes the role of finfish quarantine as a crucial step to protect established aquatic systems from external threats. Beyond disease prevention, quarantine provides a vital acclimation period, allowing new fish to adjust to different food and water conditions while minimizing stress associated with immediate competition or aggression. Ultimately, the systems have been found to be cost-effective and offer the added logistical benefit of serving as a hospital tank for future needs.

Aquaculture Disinfection with UV Light Technology

This episode discusses the application of Ultraviolet (UV) Light Technology in aquaculture as a non-chemical method for disease control. It details operational considerations for effective use, such as UV dose, UV intensity, flow rate, and UV Transmittance (UVT). The episode concludes by advising operators on proper maintenance, including lamp replacement and quartz sleeve cleaning, and lists the necessary parameters needed when sizing a UV unit for an aquatic system.

Ep 22 - Aquatic Equipment Design, Sustainability, and the Next Wave of LSS

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.

Acclimating Fish To Temperature Differences Upon Arriving At Their New Aquatic System

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.  

Protein Fractionator Function and Importance In Recirculating Aquaculture Systems

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.  

How To Calculate Vegetable Seed Quantity, Transplant Quantity, and Space Requirement For My Aquaponic 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.

The Importance of Calculating The Feed Conversion Ratio For Aquaculture Farms

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.
