The ideal temperature range for this species is 12.77°C – 23.88°C which is quite wide. They can tolerate low to fair water quality and are viable and popular eating in some areas of the world. They are hardy, adaptable, and heavy waste producers but can only be kept in low stock density. They have a high food conversion ratio and are fast-growing and omnivorous. They reach plate size in 9-12 months.
Carp are not considered to be a good fish breed for commercial aquaponics systems or in general. Nevertheless, Carp are hardy and able to survive even in low water quality compared to other fish. This makes them a good option for aquaponics. Carp in aquaponics systems will take time to grow but are a low-risk fish for an aquaponics system. Due to their low-density stocking, they do not produce sufficient nutrients unless in very large holding tanks.
Wild Carp are not widely appreciated because of “muddy” tasting flesh. Controlled aquaponics systems raise Carp that have better-tasting flesh.
Carp prefer warm and temperate climates, with an ideal range for optimum growth between 20°C – 25°C. They can survive water temperatures between 27.7°C and 30°C but slow their feeding. Some sunlight is fine for Carp tanks, but shaded areas must be provided so they can hide and cool down.
Ideally, pH levels should be between 7.5 and 8.0, and dissolved oxygen concentrations 5 mg/L and higher are ideal for them. Because they are quite hardy, they can tolerate below 2 mg/L and survive below 1 mg/L but it is not recommended.
Carp diets consist of aquatic plants but they prefer crustaceans and insects. Protein pellet feed is ideal for Carp because they need medium levels of protein. Anything extra in terms of protein in their diet is good for them. It holding tanks, Carp should be fed once a day and as much as they can eat within five minutes. Leftover feed must be scooped out to preserve water quality. One challenge that presents itself is that farming Carp can demand more water than other fish. Replacing 10-20% of the water in the tank with fresh dechlorinated tap water once a week can play havoc with pH levels.
When raised in tanks they tend to have a light flavor and can be cooked to taste without being strong on the palate.
