Problems solved by technology

If the production is carried out according to the natural spawning rhythm of the basket fish, the following problems will occur; 1. The seedlings will be listed in batches in batches, and the price of the seedlings will be low; 2. The produced fry will grow for about half a year and will be listed before the Spring Festival. The price of adult fish is not high; 3. The growth cycle is short, the size of adult fish is small, the output is low, and the economic benefit is low

Embodiment 1

[0024] (1) On November 10, 2013, four broodstock breeding ponds were prepared at the Hainan Qionghai Research Center of the East China Sea Fisheries Research Institute. Sea water, the water level is 80cm, the salinity is 27-32‰, and each pool is equipped with a constant temperature machine. Two cultivation pools (A, B) are used for cultivation and are reserved.

[0025] (2) On November 24, 2013, the natural water temperature was 22°C, and broodstock selection was carried out. Select uninjured individuals with smooth body surface and weighing more than 400g as parents, 1g / m 3 After povidone-iodine disinfection treatment, they were transferred to the breeding ponds of early breeding parents, and the number of parents in each pond was 150.

[0026] (3) After the parents were selected and stabilized in the breeding pool for one day, the temperature of the breeding pool A began to increase at a rate of 0.5-1°C per day on November 26, and the temperature was raised to 29°C on Dece...

Embodiment 2

[0030] (1) On November 15, 2014, six broodstock breeding ponds were prepared at the Hainan Qionghai Research Center of the East China Sea Fisheries Research Institute. Sea water, the water level is 100cm, the salinity is 27-32‰, and each pool is equipped with a constant temperature machine. Four pools were used for cultivation (A, B, C, D), and two were spared.

[0031] (2) On November 29, 2014, the natural water temperature was 21.4°C, and broodstock selection was carried out. Select uninjured individuals with smooth body surface and weighing more than 400g as parents, 1g / m 3 After povidone-iodine disinfection treatment, they were transferred to the breeding pools of early breeding parents, and the number of parents in each pool was 200.

[0032] (3) After the parents are selected and stabilized in the breeding pool for one day, the temperature will be raised at a daily rate of 0.5-1°C on the 1st of the 12th, and the temperature will be raised to 29°C on the 8th of December...

Abstract

The invention relates to the field of aquaculture and specifically relates to a method for early propagation of Siganus guttatus. Through technical approaches such as parent fish selection, temperature regulation, nutrition strengthening and hormone production promotion, early propagated fish fries of Siganus guttatus needed by breeding and production could be bred. The method provided by the invention has the advantages that operability is high, a spawning rate is high, season influences are small, emergence of fish fries is early, products can come into the market in advance, and the price of fish fries is high; and the earily propagated fish fries of Siganus guttatus bred by the method have a long growth cycle and a large specification for market appearance, and economic benefits can be increased significantly. Technologies are mature, safe and easy to master, can be quickly understood and mastered by farmers and are applicable to implementation of large-scale manual propagation of fish fries.

Description

technical field [0001] The invention relates to the field of fish breeding, in particular to a method for early breeding of fish from a basket. Background technique [0002] Siganus guttatus (Siganus guttatus, commonly known as golden tiger spot) belongs to Perciformes, Basketfish family, and Basketfish genus. Its meat is delicious, high in protein, rich in n-3 highly unsaturated fatty acids, and has high nutritional value. Consumers love it. Omnivorous fish has the characteristics of omnivorous, wide-salinity, and wide-temperature. It feeds on macroalgae under natural conditions. It is also a rare omnivorous fish in marine culture species, which meets the needs of the development of my country's current healthy farming model. . Basket fish, as an excellent new breeding object, has broad prospects for development and utilization. Under natural conditions, the spawning period of bluefish is from April to July every year, and spawns on the seventh to ninth day of the lunar c...
