This chapter explores the significance of common aqua crops, including plants and algae, in water gardens. Readers will learn production principles, installation, and management techniques essential for cultivating freshwater food plants and animal feeds such as watercress and duckweed. Additionally, it covers specialty plants like water hyacinths and the methodologies of hydroponics and aquaponics, which combine aquatic systems to optimize nutrient delivery and water purification. Discover the sustainable practices that contribute to efficient aquatic farming.

WATER GARDENS, PLANTS, AND ALGAE – Chapter 17 [objectives] • Identify common plant and algae aquacrops • Explain production principles • Discuss installation and management • Describe freshwater food plant culture • Describe culture for animal feeds • Describe specialty plant culture
FOOD PLANTS watercress
FOOD PLANTS Chinese water chestnuts
FEED PLANTS duckweed Water spinach
SPECIALTY PLANTS WATER HYACINTHS
HYDROPONICS and AQUAPONICS • Hydroponics - the culture of land plants with their roots in water instead of soil • Aquaponics – the same as hydroponics but the water comes from an aquaculture system • Aquaponics provides excellent nutrients to plants and cleans the water at the same time (by plant root uptake)
