Which fish and which vegetables work best together in aquaponics?

In aquaponics you want hardy fish that tolerate variable water conditions and crops that thrive in a soilless, nutrient-rich flow. Commonly used fish include tilapia where permitted, and other hardy species, chosen for tolerance and growth, though local rules on which fish you may farm vary by state so check before stocking. On the plant side, leafy greens and herbs like lettuce, basil, spinach types and mint do best because they have modest nutrient needs that match the system, while heavy-feeding fruiting crops like tomato are harder to balance with the fish load. The art is matching the number of fish and their feed to the nutrient needs of the plants, too few fish starve the plants, too many foul the water. Start with hardy fish and forgiving leafy greens while you learn the balance, then experiment. Confirm which fish species are legally allowed for farming in your state with the fisheries department, and validate the combination with a working aquaponics grower before scaling up.
