Culture techniques of giant bone hyoid fish

Giant bone hyoid fish is one of the largest freshwater fish in the world, also known as walrus fish, giant bone hyoid fish, warship dragons, etc., belonging to the remnants of paleofreshwater fish, native to the Amazon River in South America, meat can be made into dried or salt products, teeth can be used instead of files, live fish can be used for viewing, let's take a look at the culture techniques of giant bone hyoid fish!

The living habits of giant hyoid fish

Giant hyoid fish live in the world's most primitive tropical jungle waters, feed mainly on small fish, but occasionally prey on snakes, turtles, frogs and insects, and even small crocodiles. Due to the extremely hot weather and the reduced oxygen content in the slow-flowing river, the giant bony hyoid fish needs to surface from time to time to swallow air to breathe. In the dry season, you can also protect yourself by drilling holes in the sand. With strong brute force and using the tail as a weapon, it can easily knock down adult males and break bones to cause a large number of internal injuries.

Reproductive habits of giant bone hyoid fish

Giant hyoid fish spawn in shoals like salmon, gather in lakes and rivers in August at low water levels, and lay about 160000 eggs at a time from December to March. The eggs can hatch in about 3 to 5 days, when the females usually leave alone, while the males stay to protect the young. The tail of the male fish turns red to protect the eggs and take care of the newly hatched young fish, the head of the young fish is black, the head of the male fish is also black, the young fish often around the head of the male fish and do not want to leave. The juvenile fish are taken care of by their father for about three months. As the flood recedes, the adult fish and the sub-adult fish are separated and migrated to lakes and rivers. It is sexually mature at 4 ~ 5 years old, and the life span of cultured giant bone hyoid fish is 15 ~ 20 years old.

Culture techniques of giant bone hyoid fish

1. Fish tank: giant bone hyoid fish grows rapidly. It is recommended that the aquarium for giant bone hyoid fish is 4.5 meters long, 1.5 meters wide and 1.5 meters high. The 1.5 meter fish tank at home can only grow to about 1 meter at most. When you put it in a fish tank, make sure there is enough room for raising the fish and an open range of activities. If the water level of the cylinder block is low, protective measures must be taken at the top of the cylinder to prevent unnecessary losses from popping out.

2, water quality: giant bone hyoid fish is a tropical fish, like weak acid water quality, the requirement of water quality is not very strict, the suitable water temperature is between 24 degrees and 29 degrees. However, from the breeding experience over the years, as long as the giant bone hyoid fish adapt well, the water temperature can be moderately expanded to between 22 degrees and 31 degrees, but the stability of the water temperature is required and can not be changed sharply.

3. Feed: giant bone hyoid fish is a carnivorous fish. from juvenile fish to adult fish, animal bait must be fed to the small fish. the viscera of animals is easy to harm the digestive system and can not be fed. The artificial compound feed is mostly fed with shrimp feed (floating). One thing to remind you is that fish need all kinds of nutrients as much as human beings. You can't feed one kind of bait. A nutritious menu should be developed to ensure balanced nutrition.

4. Feeding: giant bony hyoid fish should not hold the fish or pieces of meat in their hands for a long time when baiting, otherwise the giant bony hyoid fish will rush into the breeders' arms, causing unnecessary danger. At the same time, giant bony hyoid fish can be mixed with any ornamental fish of similar size when they are young, and the sub-adults will take other fish as prey, so they need to be cultured separately.
