Aquaponics combines aquaculture and hydroponics in a symbiotic system, allowing vegetables and fish to be farmed together. Key advantages include tastier vegetables without chemicals, a self-sufficient vegetable and fish supply with minimal effort, and year-round harvests. However, it requires close attention to water quality factors like pH, oxygen, and nitrates. Beginners commonly fail due to overfeeding without enough plants, or not properly cycling a new system, which can kill fish. Power outages also risk high fish mortality without backups.
