Culture method of giant bone hyoid fish

Fish tank requirements: giant bone hyoid fish grow rapidly, it is necessary to choose a fish tank with a length of 4.5 meters, a width of 1.5 meters and a height of 1.5 meters, and measures to prevent escape should be taken at the top. Water quality requirements: prefer weak acid water quality, the suitable water temperature is about 24 ℃-29 ℃. Feed requirements: animal feed selection of small fish is better, with the feeding of shrimp feed to ensure balanced nutrition, can not be fed to animal viscera. Feeding method: juvenile fish can be mixed with ornamental fish and need to be cultured separately when they grow up.

I. the culture method of giant bone hyoid fish

1. Fish tank selection

(1) the giant bone hyoid fish grows relatively fast, so the tank area of the giant bone hyoid fish needs to be large, with a suitable length of 4.5 meters, a width of 1.5 meters and a height of 1.5 meters, while the common 1.5 meter fish tank can only grow to about 1 meter.

(2) when the giant hyoid fish is released into the fish tank, it is necessary to ensure a wide range of activities. If the water level of the fish tank is low, protective measures need to be taken at the top to prevent the giant bone hyoid fish from jumping out, resulting in unnecessary losses.

2. Water quality requirements

Giant bone hyoid fish belongs to tropical fish and likes to live in weakly acidic water quality, so the requirement for water quality is not very high. The suitable water temperature for growth is between 24 ℃ and 29 ℃. During this period, the stability of water temperature should be controlled and there should not be sharp changes.

3. Feed requirements

(1) Giant bony hyoid fish are carnivorous fishes, which need to be fed with animal bait from juvenile to adult. Generally speaking, it is better to feed small fish, while animal viscera is easy to cause indigestion, so they cannot be fed.

(2) the artificial compound feed can be fed with shrimp feed, and fish need to supplement all kinds of nutrients as well as humans, so they can not be fed with a single bait, but need to be equipped with nutritious food to ensure its nutritional balance.

4. Feeding pattern

(1) when feeding giant bone hyoid fish, do not hold the fish or meat in your hand for a long time, otherwise the giant bone hyoid fish will jump to the feeder's arm, resulting in unnecessary danger.

(2) Giant bony hyoid fish can be mixed with ornamental fish of the same size at the seedling stage, but other fish will be used as prey when they grow up, so they need to be cultured separately.

Second, the living habits of giant bone hyoid fish

1. Giant bony hyoid fish generally live in primitive tropical jungle waters, mainly eat small fish, and occasionally prey on turtles, snakes, frogs, insects, small crocodiles, etc., when the weather is hot, the flow rate of the river water will be relatively slow, resulting in a decrease in oxygen content. Giant bony hyoid fish often surface to breathe fresh air.

2, in the dry season, will also drill into the sediment for self-protection, giant bone hyoid fish has a strong brute force, can use the tail as a weapon, can easily knock down adult men, resulting in fractures or internal injuries.

3. Breeding habits of giant bone hyoid fish

1. Giant bony hyoid fish like salmon like to spawn in shoals, gather in groups in lakes and rivers with low water levels in August, and end the breeding period from December to March, with a spawning rate of about 160000 per spawn. generally, eggs can hatch in 3-5 days, when females usually leave alone, while males stay behind to protect young fish.

2. The tail of the male fish will turn red, thus protecting the eggs and taking care of the newly hatched young fish. The heads of both the young fish and the male fish are black, and the young fish will often surround the male fish and refuse to leave. The male fish will take care of the young fish for about 3 months. As the flood begins to recede, the adult fish and the sub-adult fish begin to separate and then migrate to live in rivers or lakes. The sexual maturity of the giant hyoid fish is 4-5 years old. The lifespan of farmed giant bone hyoid fish is generally 15-20 years old.
