Embodiment 1

[0022] A method for artificial propagation of white star snapper, comprising the following steps:

[0023] (1) Cultivate and strengthen:

[0024] Select 3-4 years old and healthy adult fish with a body weight of 1.5kg or more, and separate the male and female to cultivate and strengthen them;

[0025] Feed the compound fish feed 2 times every day, and the daily feeding amount is 4% of the fish body weight. The compound fish feed includes 18 parts of tilapia, 13 parts of saury, 4 parts of small squid and 3 parts of oysters. , after cutting the above-mentioned fish material into pieces, place it in a low-temperature dipping bath at 3-8° C. for 10 hours. The traditional Chinese medicine liquid is prepared from the following traditional Chinese medicine raw materials in parts by weight: 7 parts of Jiuxiangworm, 4 parts of Cistanche, 8 parts of Cuscuta, and Fritillaria 2 parts and 5 parts of perilla leaves, take the raw materials of traditional Chinese medicine according to the ab...

Embodiment 2

[0030] The difference between this embodiment and Example 1 is that in step (1), in the cultivation and strengthening, the compound fish feed is fed once a day, and the daily feeding amount is 3% of the fish body weight. 15 parts of non-fish, 10 parts of saury, 3 parts of small squid, and 2 parts of oysters. Before use, cut the above fish into pieces and place them in a low-temperature dipping bath at 3-8°C for 8 hours. The traditional Chinese medicine solution consists of the following parts by weight: The raw materials of traditional Chinese medicine are prepared: 5 parts of wormwood, 3 parts of cistanche, 5 parts of dodder, 1 part of fritillaria and 3 parts of perilla leaf. Take the raw materials of traditional Chinese medicine according to the above parts by weight, soak for 10 minutes, add 1 times the weight of water, and warm the fire Decoct for 30 minutes, filter to obtain the filtrate, repeat the decoction 4 times, and combine the filtrate; add 0.05% vitamin E of fish b...

Embodiment 3

[0032] The difference between this embodiment and Example 1 is that in step (1), in the cultivation and strengthening, the compound fish feed is fed 2 times a day, and the daily feed amount is 4% of the fish body weight, and the compound fish feed includes 20 parts of non-fish, 14 parts of saury, 5 parts of small squid and 4 parts of oysters. Before use, cut the above fish into pieces and place them in a low-temperature dipping bath at 3-8°C for 12 hours. The traditional Chinese medicine solution consists of the following parts by weight: The raw materials of traditional Chinese medicine are prepared: 8 parts of wormwood, 5 parts of cistanche, 10 parts of dodder, 3 parts of fritillaria and 8 parts of perilla leaves. The raw materials of traditional Chinese medicine are taken according to the above weight parts, soaked for 15 minutes, added 2 times the weight of water, and warmed Decoct for 40 minutes, filter to obtain the filtrate, repeat the decoction twice, and combine the fi...

Abstract

The invention provides an artificial propagation method of lutjanus stellatus, including the steps of selecting health adult fish at the age of 3-4 years, with weight equal to or greater than 1.5kg, and cultivating intensively by sorting male fish from female fish; feeding lutjanus stellatus with composite fish feed one or twice every day, wherein the daily feeding amount is 3-4% that of the fishweight, the composite feed comprises, by weight, 15-20 parts of tilapia mossambica , 10-14 parts of saury, 3-5 parts of tiny squid and 2-4 parts of ostracean, and is subjected to medicated bath at lowtemperature for 8 to 12 hours through Chinese herbal medicine liquid, the Chinese herbal medicine liquid is prepared from aspongopus, herba cistanches, semen cuscutae, bulb of fritillary and perillaleaf; adding vitamin E accounting for 0.05 to 0.1% of the weight of the fish into the composite fish feed every four to five days; intensively cultivating for 20 to 25 days, and performing artificialimpregnation, hatching of fertilized eggs, and growing to obtain fry. The lutjanus stellatus cultured by the artificial propagation method has good-quality eggs, high fertility rate and high hatchability rate and low malformation rate; the artificial propagation method is good for expanding of cultivation of lutjanus stellatus.

Description

technical field [0001] The invention relates to the technical field of white star snappers, in particular to an artificial propagation method of white star snappers. Background technique [0002] White star snapper (Lutjanus stellatus), a species of fish in the family Snapperidae. The side of the body is flat and the mouth is large. Body color reddish brown or yellowish brown, characterized by an obvious small white spot above the lateral line below the 3rd to 4th soft rays of the dorsal fin. White star snapper fish is not only tender and delicate, with less bone, but also rich in nutritional value. First of all, it is rich in essential amino acids. The fat content in fish meat is less and mostly unsaturated fatty acids. Compared with the saturated fatty acids contained in the meat of land animals such as pigs, cattle, and sheep, it is easier to be absorbed by the human body, especially omega-3 unsaturated fatty acids can degrade cholesterol. Help fatty acid metabolism, ...
