Problems solved by technology

Now it is not enough to rely on wild fishing of barracuda seedlings alone, not to mention that wild barracuda seedlings are subject to great changes in external interference, and there are many uncontrollable factors. Limited numbers create instability for the aquaculture industry

Embodiment 1

[0019] The barracuda land-based self-produced artificial breeding method of the present invention comprises the following steps:

[0020] 1) Prepare the land-based barracuda parents to stock the cement pond: clean and clean the cement pond, and disinfect the whole pond with 20ppm bleach for 24 hours (including the inflatable tube and inflatable head), rinse it, and expose it to the sun for use. The size of the cement pool for stocking is 30.0×5.0×1.5m according to 5m 2 Equipped with 1 inflatable head, a total of 30 inflatable heads are equipped. Check whether the scaffolding and insulation film on the cement pool are intact and firm. Finally, prepare the pool water before stocking the barracuda parents, and add the natural seawater in the local estuary area filtered by 150-200 mesh sieve silk net in 2 / 3 of the whole pool;

[0021] 2) Select qualified parents: Generally, at the end of February every year, select parents that meet the requirements of oxytocin from the outer po...

Embodiment 2

[0029] The above-mentioned implementation method has been carried out in the Fengxian Research Base of the Shanghai Fisheries Research Institute for three consecutive years. In late February each year, the pike parents are selected from the outer pond and moved into the land-based cement pond for parental strengthening. In early March, the salt is raised to the target level. 5 In the first ten days of the month, labor is induced and reproduced. March 4, 2019 at Base 1 # The pond with an area of ​​3 mu in the north selects the parents of pike, 12 ♀ 24 ♂, a total of 36 fish are put into the land-based East 4 # For the cement pool (30.0×5.0×1.5m), salt was raised three times on March 10, 13 and 16, and the salinity rose from 12.0‰ to 22.1‰, and the water was changed once on April 20. On May 9th, 5♀10♂ was selected for induced labor, divided into two induced labor: 16:00 pm and 16:00 pm the next day, the induced labor was completed and moved to the new pool (Lujidong 1 # Cement ...

Abstract

The invention relates to the field of aquaculture, in particular to a land-based artificial breeding method for barracudas, which includes: preparing land-based barracuda parents to stock cement ponds, selecting qualified parents, raising salt, daily cultivation and management of parents, induced production and reproduction, collecting fertilized eggs, Indoor seedling ponds hatch and raise seedlings, and finally put them into the outer pond for seedling cultivation. In the present invention, parental breeding can be carried out by moving from the outer pond to the land-based cement pond for refined management, precise feeding, precise temperature control, and precise water control, which play a positive role in the development and maturation of the parental gonads of the barracuda; reduce the use of brine; change artificial insemination to Natural spawning; reduce labor intensity, reduce the death rate of parental induced labor; the effect of induced labor is good, the fertilization rate is high, the fertilization rate and hatching rate of natural spawning are over 90%, and the growth rate of indoor seedlings is 65-70%, which is 20% higher than conventional above. The invention is easy to operate and easy to be accepted and popularized by people.

Description

technical field [0001] The invention relates to the technical field of aquaculture, in particular to a land-based artificial breeding method for pike. Background technique [0002] Barracuda (Liza haematocheila), also known as red-eyed mullet, commonly known as red-eyed mullet and meat stick, belongs to the order Mulletidae, Mulletidae, and the genus Barracuda. ​​It is distributed in the Indian Ocean and the western coast of the Pacific Ocean. It is an important economic fish in temperate shallow seas. One, it has the characteristics of wide salt, wide temperature, wide food, rapid growth, strong stress resistance and so on. The age of sexual maturity of barracuda is generally 2-3 years old for males and 3-4 years old for females. From April to June every year, barracudas lay eggs in various estuary areas and only do short-distance migratory migrations, and begin to winter in the depths of sea water in December. Barracuda is rich in nutritional value, the meat is fresh and...
