Problems solved by technology

Due to the early development and utilization of mullet resources and the lack of scientific management, the amount of this resource has decreased significantly in the past 10 years. Even if the fishing intensity increases, the output will hardly increase, which will lead to a decline in benefits
At present, the natural resources of mullet can no longer meet the needs of the market. Carrying out artificial breeding of mullet, carrying out release and multiplication and artificial breeding are effective ways to solve the problem
Domestic research on mullet breeding is less; the existing single-type fish fertilizer and compound fish fertilizer also have a common shortcoming, that is, they cannot kill harmful bacteria and insects, so they lack the effect of effective prevention and treatment of fish diseases
The microbial compound fish fertilizer can increase the content of beneficial bacteria in fish ponds and effectively reduce the occurrence of fish diseases. At present, there is no report on the special use of this compound microbial fish fertilizer

Embodiment 1

[0022] A method for scientifically raising mullet in a paddy field, comprising the following steps:

[0023]Selection of paddy fields: choose fields with open ground, flat terrain, good water retention, sheltered from the wind and sunny, quiet environment, convenient transportation, and supporting electricity. The bottom material is clay, and the bottom mud is about 15 cm. The outlet is about 20 cm deeper than other places, which is convenient for drainage and adult fish fishing. Install 40-mesh anti-escape nets at the inlet and outlet of the pond;

[0024] 10 days before putting in fish species, first dry the pond and remove the weeds in the pond, disinfect the pond with quicklime 1 125 kg / hm2, apply 1000kg of decomposed semi-dry and semi-wet pig and cow dung per mu, and evenly fertilize Sprinkle it on the bottom of the pond and bury it in the mud with a rake to keep the fertilizer effect for a long time to cultivate large zooplankton, so that fish species can have palatable ...

Embodiment 2

[0032] The preparation method is the same as in Example 1.

[0033] In the mullet juvenile stage of growth, fish out, divide and raise in the middle of five ponds, every pond 300, in four ponds, drop respectively the microorganism mullet of the embodiment of the present invention 1 and common fertilizer ( Control 1, from Beijing Century Arms Biotechnology Co., Ltd. ), the other pond did not put in the mullet fertilizer (control 2), but put in the same amount of common fish food, the rest of the feeding amount was the same, and the cultivation environment was the same. After 2-4 months of breeding, the production and the growth of the mullet were compared. , specifically as shown in Table 1 and Table 2:

[0034]

[0035]

[0036] Through the comparison of table 1 and table 2, it can be found that adding the compound microbial fertilizer of the present invention can promote the rapid growth of mullet, increase the EPA content, reduce the disease of mulle...

Abstract

Disclosed is a method of scientifically raising Chinese high fin banded sharks in paddy fields. According to the method, a culture pond is a round or square cement pond, 12-20m<2> in area and 0.7-1.0m in depth; the pond has the functions of water circulation and pollution discharging; the water in the pond is clear, with no harmful heavy metal ions; 70-100cm deep water is poured into the pond first; the water is then sterilized with 0.3mg / L DBDMH; robust and healthy fishes of the Chinese high fin banded sharks are put into the pond. The Chinese high fin banded sharks fed with the compound microorganism fertilizer can grow fast, with higher EPA content and fewer Chinese high fin banded shark diseases, and less Chinese high fin banded sharks die of illness; in addition, the beneficial organisms in the water are more; the final quality and mass of the Chinese high fin banded sharks is increased. After the method is used to raise the Chinese high fin banded sharks scientifically and finely, the yield is obviously increased in a short period of time, the survival rate is high, and the method is suitable for industrial large-scale development.

Description

technical field [0001] The invention relates to a method for aquaculture, in particular to a method for artificial breeding of mullet. Background technique [0002] The mullet (Myxocyprinus asiaticus) belongs to the order Cyprinidae, the submouth fish family, and the genus Myxocyprinus. Commonly known as: fire bream, yellow row, wooden leaf plate, red fish, purple bream, swallowfish, blood row, powder row. Distribution: Yangtze River, Jinsha River and other places. Habitat: Lives in lakes and rivers. Juveniles and adults have different shapes, habitats and biological learning. Juveniles like to cluster among gravels with slow water flow, and mostly move in the upper layer of water bodies, while subadults live in the middle and lower layers , adults like to live in the open water area of ​​rivers, and their actions are fast and agile. Predation and food: Mainly feed on invertebrates and insect larvae, also eat organic matter at the bottom of the water, and often suck diato...
