This video briefly describes the course content and the curriculum for the course.
Aquaponics merges aquaculture and hydroponics, using fish waste to feed plants that purify water, with historical practice from Maya raft farms to ancient Asian integrated systems.
Modern aquaponics combines recirculating aquaculture systems with soil-based growing to save water and space. It traces developments from Dr James Rowe Cosi to deep water culture beds and broader adoption.
Explore nitrogen's role in aquaponics, including ammonia and nitrate cycles, the nitrification steps, and how a biofilter activates, with safety thresholds for ammonia and nitrate before stocking fish.
Explore pH in aquaponics, where the 0–14 scale reflects hydrogen ion concentration, with below seven acidic, above seven basic, and seven neutral, and how pH influences other parameters except temperature.
Explore how water pH governs nutrient availability in aquaponics, including phosphorus, nitrogen, potassium, and sulfur. The ideal pH range of 6.5–7.5 supports root growth and nutrient uptake.
Keep dissolved oxygen at least 3 mg/L for fish and about 10 mg/L for optimal health of fish and plants, and ensure backup aeration as water warms.
Explore aeration in aquaponics by comparing blowers and compressors, determining operating pressure and air volume at diffusers, and sizing diffusers and air sources for backyard and commercial systems.
Manage ammonia, pH, and temperature to protect fish health. Warmer water and higher pH increase ammonia toxicity, while cold water stores more dissolved oxygen.
Explore macronutrients in aquaponics, focusing on nitrogen, phosphorus, and potassium and their roles in growth. Secondary nutrients like calcium, magnesium, and sulfur support chlorophyll formation and photosynthesis.
Analyze nutrient antagonism to see how nutrient interactions and excesses displace elements, enabling balanced uptake and improved diagnosis and management of deficiencies in aquaponics.
Carbon dioxide boosts plant growth by increasing photosynthesis. At about 1000 ppm, roughly three times ambient, CO2 can double photosynthesis; growers use CO2 generators and condensers as sources.
Explore how beneficial insects enable integrated pest management by predation, using ladybugs, predatory mites, green lacewings, and wasps to control aphids and mites.
Explore backyard aquaponics design ratios, from one-to-one grow beds to fish tanks for simple filtration, and advance to two-to-one configurations for greater beds and capacity.
Explore a commercial aquaponics case study, designing a pilot greenhouse system with 20-foot by 48-foot space, 640 square feet of grow beds, and detailed feed, fish, and water calculations.
The course is designed for someone with or without the basic understanding of how aquaponics works and also for those who are looking to enhance their knowledge of the science, the operations and the design process of building an aquaponics farm, both backyard and small commercial scale. This course contains materials derived not only from the experience of running a small commercial farm but also from academic research on aquaponics conducted in the past two decades.
Are you looking to master the key operational techniques of aquaponics required to operate a backyard or commercial size system?
Get a solid understanding of how aquaponics functions and how you can master all aspects of growing in aquaponics?
Are you tired of searching the internet for answers in so many different places?
There are several resources on the internet that help you learn the basics of aquaponics but in this course we will dive deeper into the science behind aquaponics, how to create an optimal environment for your symbiotic ecosystem, understand fish and fish husbandry so you can produce market ready fish, plant nutrients and how to create an optimal balance so you can maximize both plant and fish growth, pest management and control so you can protect your investment and finally we will put all this newly acquired knowledge into a case study that shows you exactly how to design a small commercial size aquaponics system. The material is put together specifically with the intention to give you the information you need for the "How-To's" of your aquaponics project and covers more than many of the 2-3 day long workshops offered for a fraction of the price.
