Artificial culture of giant bone hyoid fish in Guangdong

Guangdong giant bone hyoid fish can be cultured in water tank, and the suitable size of water tank is 4.5m in length, 1.5m in width and 1.5m in height. Giant bony hyoid fish belongs to tropical fish and likes weakly acidic water quality. During the growth period, the water temperature should be kept between 24 ℃-29 ℃, which can be cultured with nutritious animal bait, and protective measures should be taken when feeding. It can be mixed with other fish in the seedling period, but should be cultured separately when growing up.

First, water tank culture

1. As the giant hyoid fish grows fast, we should try to choose a larger one when choosing a water tank. The common 1.5m water tank on the market can only raise the giant bone hyoid fish to about 1m, so we need to replace the large water tank. The more suitable tank size is 4.5m × 1.5m × 1.5m.

2. When breeding giant bone hyoid fish in the water tank, we need to ensure that it has enough room for movement. If the water level is relatively low, protective measures must be taken at the top of the water tank. If the giant bone hyoid fish is allowed to jump out, it will cause some damage to it.

Water quality and water temperature

Giant bony hyoid fish is a tropical fish, which likes to live in weakly acidic water quality, so the requirement of water quality is not very strict, and the suitable growth water temperature is between 24 ℃ and 29 ℃. Therefore, in the process of culture, it is necessary to maintain the stability of water temperature and should not change sharply.

Third, feed the bait

1. Giant bony hyoid fish is a carnivorous fish. from juvenile fish to adult fish, it is necessary to feed an appropriate amount of animal bait, mainly to feed active small fish, but not to feed animal viscera, which will easily lead to indigestion.

2. It can be fed with animal bait, and fish, like people, need to supplement rich nutrients, so it is not suitable to feed too single bait, it needs to be matched with a variety of rich bait, which is helpful to meet the nutritional needs of giant bone hyoid fish.

IV. Points for attention in feeding

When feeding giant bony hyoid fish, do not hold small fish or pieces of meat in your hands for a long time to prevent the giant bony hyoid fish from attacking the feeder and causing unnecessary damage.

5. Mixed culture with other fish

Giant hyoid fish are in the seedling stage and can be mixed with ornamental fish of the same size, but when they grow up, they will regard ornamental fish as prey, so they need to be cultured separately at this time.

VI. Breeding habits of giant hyoid fish

1. Giant bony hyoid fish and salmon have the same habits and like to lay eggs in shoals. Generally, in lakes with low water levels in August, groups of rivers begin to gather until they stop breeding from December to March, with about 160000 eggs per spawning. They usually spawn in batches and wait for 3-5 days to hatch, when the females leave alone, while the males stay behind to protect the young.

2. during this period, the tail of the male fish will turn red, which will help to protect the eggs, and take care of the newly hatched young fish. The heads of both the young fish and the male fish will be black, and the young fish will often surround the male fish and refuse to leave.

3. The male takes care of the juvenile fish for about 90 days and leaves with the flood. At this time, the adult fish and sub-adult fish will separate and migrate to lakes or rivers to live. The giant bony hyoid fish enters the mature stage at the age of 4-5, and the farmed giant bony hyoid fish has a life span of about 15-20 years.
