Aquaponics is considered to be an alternative 'food production system' that combines conventional aquaculture, in a symbiotic manner with hydroponics! This can be daunting job especially for those who are just starting because they have to be careful while choosing the plants and the animals to be used so that they are well compatible to make the aquaponics project a success. In this article you can get a fair idea about the types of fishes that thrive well with minimal hassle, and may be used for this food production system.
The first two types are edible varieties and the other two ornamental yet effective. Let's check them out...starting with,
One of most well-known and common fishes used in aquaponics is tilapia. Tilapias are very hardy and easy to breed and do not require any extra special care . Once you leave them in your aquaponic system, they will grow and breed fast and steadily as long as the ratio between the male and female tilapias is balanced. Furthermore, maintenance of your aquaponic system will not be very costly as tilapias can withstand almost all types of water conditions, including not-so-good ones. However, it is required to maintain the warmth of the water at a certain degree that is appropriate for this species. This fish type is highly suggested for beginners because they are edible and can be sold to set up a good source of business to start with.
Another fish type that you can breed in your aquaponics system is catfishes. Catfishes are generally found to be present in most water-bodies, especially inland waters and sweet-water. Like tilapia, catfishes are mainly bred for consumption and to be sold as food.
They are good for your aquaponics system because their excreta contribute significantly in helping the aquatic plants in your system grow healthily and fast. They are worthy to breed in big numbers because they have a high commercial value in the market.
If you want to breed a type of fish not for any consumption purpose, then goldfish can be a good choice. Basically they are more of an aquarium fish.
Goldfishes are highly recommended for an aquaponics system because if they are fed well adequately and consistently, they can produce a lot of 'waste' which serve very well as fertilizer for the aquatic plants you're cultivating in your aquaponics set-up. However, you need not worry about feeding them with the store-bought fish food all the time because they also eat a small amount of the plant matter present in the system as well as a certain insect species.
Another type of fish good for the aquaponics system is guppies. They mainly feed on what is available in their habitat and adjust their diet depending on what is available. Guppies can increase in number rapidly if bred properly in a correct male: female ratio. Because of this, you may profit from your aquaponics system through the large production of numbers. Guppies too are not edible, however, you can profit from them by selling them as aquarium fishes to aquarium enthusiasts!
This was a brief overview on 4 fish species that are relatively hardy, easy-to- breed to start your aquaponics venture successfully with minimal expense and risk!
