Problems solved by technology

According to the existing research data, it takes more than 100 days for lobsters to undergo a long developmental metamorphosis period from fertilized eggs to complete metamorphosis. It is one of the most complicated and difficult species in the artificial reproduction process of all aquatic economic animals. The living habits and nutritional requirements of different developmental stages are different, and the bait series in the artificial breeding process has not been established; there are only sporadic reports on the larvae of Chinese lobsters in China (the artificial breeding of Chinese lobsters and the cultivation of early phyllodes larvae Research, Chen Changsheng et al., Fujian Aquatic Products, Issue 3, September 2003; Research Progress in Lobster Reproductive Biology and Larval Cultivation, Liu Huiling et al., 2006, Journal of Zhanjiang Ocean University, Volume 26, Issue 6, December 2006), Moreover, it is reported that the survival time of Chinese lobster larvae artificially cultivated does not exceed 28 days, and there are no special reports on larvae cultivation technology and biological bait series; in the international arena, there are relatively more research data on individual species of lobster larvae, but there is no complete cultivation Technical route and bait series
Therefore, there is currently no method for cultivating Chinese lobster larvae in batches

Embodiment １

[0035] The salinity of the water body is maintained between 29-32, the water temperature is maintained between 25-27°C, and 30% of the water is changed every day. The algae added to the water body is Chlorella, the concentration of which is between 20000-50000 cells / mL. Its main function is to absorb ammonia nitrogen in the water body, and at the same time serve as food for artemia and copepods.

[0036] Put 200 Chinese lobster larvae that have been hatched for about 12 hours in the aquarium, and start feeding Artemia nauplii from the first day, and at the same time add a small amount of scallop fertilized eggs and copepod nauplii (filtered with 80 mesh net filter). To the 15th day, under the situation of continuing to throw something to feed Artemia nauplii, gradually increase the proportion of copepod adults, said copepod adults account for 0-65% of the total weight of the bait, and said copepod adults include Planktonic copepod adults and mural copepod adults, among which th...

Embodiment 2

[0038] The salinity of the water body is kept at about 30, the water temperature is maintained at 25-27°C, and 35% of the water is changed every day. The algae added to the water body are chlorella and diatoms. The total concentration of algae is between 20000-50000 cells / mL.

[0039] Put 150 newly hatched Chinese lobster larvae into the aquarium, start feeding copepod nauplii (filtered with an 80-mesh filter) from the first day, and supplement fertilized scallop eggs in a small amount at the same time, until the 17th day, In the case of continuing to feed the above bait, add copepod adults as the bait for Chinese lobster larvae, and gradually increase the proportion of copepod adults in the bait. 65%, the copepod adults include planktonic copepod adults and mural copepod adults, and the number of planktonic copepod adults accounts for more than 90% of the total number of copepod adults. From the 26th day, the mural copepods, mainly Daphnia japanese tabby and Daphnia acupoint...

Embodiment 3

[0041] The salinity of the water body is kept at about 30, the water temperature is maintained at 25-29°C, and 25% of the water is changed every day. The algae added to the water body is Phaeodactylum tricornutum, its concentration is between 20000-50000 cells / mL, its main function is to absorb ammonia nitrogen in the water body, and at the same time as food for artemia and copepods.

[0042] Put 250 newly hatched Chinese lobster larvae in the aquarium, and start feeding Artemia nauplii from the first day, and at the same time add a small amount of fertilized scallop eggs and copepod nauplii (filtered with an 80-mesh filter) . On the 13th day, under the condition of continuing to feed Artemia nauplii, gradually increase the proportion of copepod adults, which account for 0-65% of the total weight of the bait, and the copepod adults include Planktonic copepod adults and mural copepod adults, among which the number of planktonic copepod adults accounts for more than 90% of the ...

Abstract

The invention provides a cultivation method of panulirus stimpsoni larva, which comprises the steps of: A. cultivating the hatched panulirus stimpsoni by a first bait for 13-17 days, wherein the first bait comprises at least one of the artemia nauplii, the scallop fertilized eggs, the oyster fertilized eggs and the planktonic copepodid larva; B. cultivating the panulirus stimpsoni by a second bait for 8-12 days, wherein the second bait comprises the first bait of the step A and the copepodid adult; and C. continuously cultivating the panulirus stimpsoni larva till that the panulirus stimpsoni larva is completely mutated into thelarva, wherein the bait comprises a third bait, and the third bait comprises the mural copepodid adult. The cultivation method of the panulirus stimpsoni larva can cultivate the panulirus stimpsoni larva in bulk, and is high in survival rate, high in mutation rate, and high in growth speed.

Description

technical field [0001] The invention relates to the field of aquaculture, in particular to a method for cultivating lobster larvae, in particular to a method for cultivating Chinese lobster larvae. Background technique [0002] Chinese lobster (Panulirus stimpsoni Holthuis) is a unique species in my country. It is mainly produced in the South China Sea, the southern part of the East China Sea and the coast of Taiwan Province. It lives in shallow seas with a water depth of 40-70 meters. [0003] The larval cultivation technology of lobsters is a worldwide problem, and the unclear bait series for larvae is an important reason. According to the existing research data, it takes more than 100 days for lobsters to undergo a long developmental metamorphosis period from fertilized eggs to complete metamorphosis. It is one of the most complicated and difficult species in the artificial reproduction process of all aquatic economic animals. The living habits and nutritional requiremen...
