Embodiment 1

[0025] In April 2017, the researchers conducted relevant verification experiments in the aquaculture base of Qingkou Town, Lianyungang City. The yield and quality of barramundi were measured after harvest. The results are shown in Tables 3 and 4. The specific methods are as follows:

[0026] S1. Pond selection and pre-use treatment: Select a pond close to the sea, with convenient water and drainage and no industrial pollution as the barramundi breeding pond. Before using the pond, drain the water in the pond and expose it to the pond for 5-10 days The bottom mud is dry and cracked, and the whole pond is sprayed with 80-100kg of quicklime per mu for disinfection; 2 days after the disinfection is completed, water is injected, and after 7-10 days, fertilization and watering are applied, and 200-300kg of water and fertilizer are put into the mu; the composition of water and fertilizer is by weight: fermented chicken manure 60. Soybean meal 35, peanut meal 15, corn stalk 22, rice br...

Embodiment 2

[0032] In order to verify the beneficial effects of laser irradiation, magnetized seawater and incubation-promoting fluid in the inventive route, researchers conducted relevant comparative verification experiments in the laboratory in April 2017. The specific methods are as follows:

[0033] The present invention: adopt the method step in S2 in the embodiment 1, cultivate 300 grains of barramundi fertilized eggs, after hatching, count the hatching success rate and hatching time, the obtained results are shown in Table 1.

[0034] Treatment with laser irradiation alone: ​​except that the magnetized seawater in S2 in Example 1 was replaced with ordinary seawater and no incubation-promoting solution was applied, the same method steps were used to cultivate 300 barramundi fertilized eggs from the same source. After hatching, the hatching success rate and hatching time were counted, and the results are shown in Table 1.

[0035] Single use of magnetized seawater treatment: except t...

Embodiment 3

[0041] In order to verify the beneficial effects of the fry adapting liquid applied during the pre-stocking and desalinating stages of the route of the present invention, researchers did relevant comparative verification tests in the laboratory. The specific method steps are as follows:

[0042] The present invention: using the method steps in S3 in Example 1, pre-stocking and desalinating 300 barramundi larvae, after the desalination is completed, the survival rate and health of the fry are counted, and the obtained results are shown in Table 2.

[0043] Conventional desalination: using the conventional method, that is, without applying the fry adaptation solution, 300 barramundi larvae from the same source were desalinated. After the desalination was completed, the survival rate and health of the fry were counted. The results are shown in Table 2.

[0044]

[0045] Analyzing Table 2, we can see that adopting the route of the present invention to process the desalinated bar...

Abstract

The invention discloses a quality-improving and yield-increasing breeding method for high-quality lates calarifer. The method comprises the following steps of S1, pond selection and processing beforeuse; S2, artificial incubation and fry breeding; S3, fry pre-breeding, desalting and management; S4, fry stocking and feed management; S5, harvesting. Lates calarifer eggs are bred through a magneto-optical induction method, the water quality is improved after seawater is magnetized, the content of dissolved oxygen in a water body is increased, and fish egg development and incubation are facilitated. Laser irradiation is beneficial to killing germs in the water body environment and improving the disease resistance of fry. The application of hatching promoting liquid further promotes incubationof the fish eggs and improves the physique of the fry. Fry adapting liquid is applied in the fry pre-stocking stage, so that the fry are helped to adapt to the low-salinity water environment as soonas possible, fishes are strengthened, and disease resistance of the fishes is improved. By applying matched feed conforming to nutrition requirements of various growth and development periods of the lates calarifer, the effect of fully utilizing the feed is achieved; finally, the goal of improving the quality and yield of the lates calarifer is achieved.

Description

technical field [0001] The invention relates to the field of aquaculture, in particular to a method for cultivating high-quality barramundi for improving quality and increasing production. Background technique [0002] Barramundi ( Lates calcarifer ), also known as golden-eyed perch and blind scorpion, belongs to the order Perciformes, the genus Spermatidae, and is a large edible fish with a wide range of temperature and salt. It is an important economic fish in brackish water aquaculture and is widely distributed in Tropical and subtropical sea areas of the Western Pacific and Indian Ocean, southern East China Sea and South China Sea, India, Myanmar and other places. Barramundi grows fast, and can reach a growth rate of 1kg / year within a one-year breeding cycle. The meat is firm, white and tender, and has a fragrant taste. It is a rare and high-quality seafood species. Barramundi are easy to domesticate and cultured in cages and ponds. They have low requirements for feed ...
