Embodiment 1

[0021] A quick-raising method for mullet, comprising:

[0022] Fry disinfection: Soak the fry in salt water with a mass fraction of 3% sodium chloride for 20 minutes before the fry are thrown into the pond. The fry are 2 cm long, with complete scales and no damage;

[0023] Fishpond bottom improvement: Put quicklime in the fishpond without water, the dosage is 2 tons / ha, after 10 days, pour water into it to the water depth of 0.03-0.1m, and then put quicklime into it, the dosage is 3 tons / ha; Then lay 18cm thick silt on the bottom of the pool and inject water, the water injection depth is 1m, the transparency of the pool water is 40cm, and the pH is 7.5;

[0024] Pond management: the feed is fed 3 times a day, at 5:00 in the morning, 12:00 noon and 19:00 in the afternoon, and the amount of feed fed every day is 3% of the total weight of the fish; the feed is high-protein compound feed and meat. A mixture of similar feeds, the weight ratio of the high-protein compound feed to ...

Embodiment 2

[0027] A quick-raising method for mullet, comprising:

[0028] Fry disinfection: Soak the fry in salt water with a mass fraction of 5% sodium chloride for 10 minutes before the fry are thrown into the pond. The fry are 3 cm long, with complete scales and no damage;

[0029] Improve the bottom of fish ponds: put quicklime in the fish pond without water, the amount of which is 3 tons / ha, after 5 days, inject water into it to a water depth of 0.1m, and then put quicklime into it, the amount of which is 4 tons / ha; Lay 25cm thick silt on the bottom of the pool and inject water, the water injection depth is 1.8m, the transparency of the pool water is 50cm, and the pH is 7.6;

[0030] Pond management: the feed is fed 3 times a day, respectively at 6 o'clock in the morning, at 13 o'clock in the morning and at 20 o'clock in the afternoon, and the amount of feed fed every day is 4% of the total weight of the fish; the feed is high-protein compound feed and meat Class feed, the weight r...

Abstract

The invention discloses a quick breeding method of mullets, which comprises the following steps of: sterilizing fish fries: wherein the fish fries are soaked in saline water with a mass fraction of 3-5% of sodium chloride for 10-20min before the fish fries are put into a fish pond; bottom change of the fish pond: wherein quicklime is poured into the fish pond without water, the amount is 2-3 tons / hectare, after 5-10 days, the water is injected into the fish pond until the water depth is 0.03-0.1m, and then the quicklime is poured into the fish pond, the amount is 3-4 tons / hectare; and then sludge is laid on the bottom of the fish pond and the water is injected. According to the invention, the survival rate and growth speed of the mullets are improved, and meanwhile, the meat quality of thefish is ensured to be more fresh and tender.

Description

technical field [0001] The invention relates to a mullet culture technology, in particular to a quick-raising method for a mullet. Background technique [0002] Mullet is also known as black fish, raw fish, snakehead fish, cayenne fish, etc. Its meat is tender, delicious, and has high nutritional value. Therefore, it is very popular in domestic and foreign markets, and it is a high-quality dish that people love. The snakehead has no strict requirements on the external environment, and has a strong ability to adapt to life. It can still survive even in waters with insufficient dissolved oxygen. The mullet has low requirements on breeding, grows rapidly, and is convenient to transport. In recent years, with the development of domestic aquaculture and the needs of foreign trade, mullet has gradually become a family of special breeding species, and the breeding technology of mullet has begun to attract people's attention. and attention. Contents of the invention [0003] The...
