Breeding Techniques for the Endangered, High Economic Value Arapaima (Pirarucu)
The arapaima is also called the pirarucu, and it is a fish that has survived from ancient times to the modern day. Because of human fishing, it is now endangered. Many people keep it as an ornamental fish, so let us take a look at how the arapaima is bred.
1. The breeding fish tank
The arapaima grows very quickly, so when keeping it as an ornamental fish you need to use a fairly large fish tank; in a small tank the fish cannot stretch out, and so it will not grow large. The tank used for stocking must ensure the fish can move around normally. It is recommended to use a rectangular tank 4.5 m long, 1.5 m wide and 1.5 m high.
2. Water quality management
The arapaima is a tropical fish, and its requirements for water are not too high; slightly acidic water is sufficient. The temperature can be kept at the temperature at which ordinary tropical fish live, that is, between 15°C and 29°C. However, more and more people are now keeping this kind of fish, and it has been found that the fish is not very strict about temperature; as long as the temperature stays stable between 22°C and 30°C, it will not resist, but the water temperature must be stable and must not change suddenly.
3. Feed management
The wild arapaima is a carnivorous fish, so when we keep it we must also feed it meat-based feed. Whether it is a juvenile or an adult fish, it is best to usually feed it bait fish, but they must be washed clean and their internal organs removed, because these will affect the arapaima's digestive system. When feeding artificial feed, choose floating prawn feed. Fish also need a variety of nutrients for growth, so when feeding, pay attention to the balance of nutrients.
4. Feeding method
When feeding the arapaima, you must not hold the food in your hand to feed it, because it is fairly ferocious and may injure your fingers. If other ornamental fish are kept together with this fish, they may be swallowed by it as prey. When the fish is still small, you can keep some of similar size with it.
