When you start an aquaponics system, you often ask yourself what kind of fish to raise without knowing which one to choose. To answer this recurring question, we propose a small ranking of the 7 easiest fish to raise in aquaponics and for which your aquaponic system will behave in an optimal way.

fish

1) Tilapiatilapia

Consumable: Yes
Easy to manage
Rapid growth
Can withstand very bad water conditions
Requires hot water> 15 ° C
Most Cichlid species, about a hundred, are better known as Tilapias. They are found in shallow streams, ponds, rivers, and lakes. They feed on algae and herbal food which makes them so common in aquaculture.
Their large size, fast growth, and palatability make them intensively farmed as food fish, especially Nile tilapia. They are a good source of protein and are very popular among artisanal and commercial fisheries.

2) Trout

Consumable: Yes
Ideal for cool temperatures (10 ° C -20 ° C)
Very fast growth rate
Excellent feed conversion rates
Trout are closely related to salmon and are carnivorous, feeding on fish and other soft-bodied aquatic invertebrates such as flies, mollusks and mud worms among other insects.
Their environments are different and they may have radically different coloring patterns, which act like a camouflage when they move in their different habitats. Trout are often raised in fish farms and are an important source of food for animals and humans.

3) Goldfish

Consumable: No
Usually needs a vegetative cover to reproduce in the tank
The goldfish is a small member of the carp family. It is one of the first fish to be domesticated and perhaps the most popular fish in the aquarium. In the wild, he eats crustaceans, insects, and various vegetable matters. They go well in small tanks like Nanos. Make sure to get all the necessary accessories too. Read some protein skimmer reviews if you need some ideas.
If it is supercharged, it produces more waste, which makes it good for your aquaponic system. However, because of their small size, lack of protein and susceptibility to parasites, goldfish are not recommended for consumption.

4) Carp

Consumable: Yes
Good breeding abilities
Can adapt easily to various environments
Carp is a species of oily freshwater fish. They are very popular in recreational fishing and aquaculture. Various species are domesticated and used as food fish. In Western Europe, demand for carp as food has declined since trout and salmon became more available through livestock.
Among the most common species of carp to be consumed are bighead carp, carp, mud carp and crucian carp. They feed on algae, plants, mollusks, insects and many other soft-bodied aquatic invertebrates.

5) Catfish

Consumable: Yes
Need to be skinned because they do not have scales
Rapid growth
Good food and conversion ratio
Catfish have a group of ray-finned fish that vary considerably in size. They are found in freshwater environments and live in the land or coastal waters of all continents except Antarctica.
Commercially, catfish are of great importance and many of the larger species are grown or fished for food, especially in warm climates.
Catfish can feed on plant-based food, insects, and other fish, but some catfish species will have a specific diet. The catfish is rich in vitamin D and among the species consumed, the most common are the bearded river and the blue catfish.

6) Koi

Consumable: No
Can thrive in an aquaponic system
Long life expectancy
High resistance to common pests
Koi were developed from common carp in Japan and is part of the same family. It varies greatly in coloring and patterns that have made them popular for ornamental purposes. Koi is a sustainable fish species, which has a strong resistance against many common pests. They also have a very long life. It is a type of omnivorous fish in order to have a varied diet that consumes peas, lettuce, watermelon, seaweed and other fish. Although they are perfect for aquaponics, adequate oxygenation and gas release must be monitored, which is essential especially in the winter months and small ponds.
Although they can be eaten, they tend to have very large scales that need to be removed. They are also generally more expensive than other carp, and there are other fish that are tastier and easier to prepare.

7) Largemouth bass

Consumable: Yes
Very varied diet
Tasty in the water at low temperature
Largemouth Bass is an olive-green fish that is part of the Moonfish family and is a popular freshwater fish. In its youth, it feeds mainly on small baitfish, gamma rays, small shrimps, and insects, while adults will eat small fish such as bluegill, snails, crayfish, snakes, waterbirds and other small mammals.
In an aquaponic environment where their diet and the cleanliness of the water are controlled, they have a much better taste than in the wild. Although generally, largemouth bass has a stronger taste compared to much other fish.

Conclusion

Almost all freshwater fish are edible, but their taste, health, and ease of preparation must be taken into consideration.

It is essential that you take good care of your fish because they are the lifeline of your aquaponic system. The different guides and quality food will ensure that your fish are healthy.
Another thing to keep in mind is that fry is cheaper but take longer to mature which means they will also take longer to produce adequate levels of nitrates for your plants.
On the other hand, young fish are more expensive, but they produce more waste, which means an earlier start in growing vegetables.

Another option is to simply buy mature fish but it will cost you more. Make sure you do not mix fry and adult fish as they can be used as meals for others.
The best is to try the different options over a period of time to see what suits you best.
