Problems solved by technology

However, due to the rapid development of breeding and unscientific management, in recent years, sea cucumber pond culture is facing many problems: such as: the decline in the quality of the offshore environment, the decline in the quality of seedlings, and the occurrence of breeding diseases all restrict the continuation of the industry. stable and healthy development
However, the above-mentioned prevention

Example Embodiment

[0018] Example one

[0019] In 2009, in the Zhuanghe Huangguzui sea cucumber breeding pond, the pond area was 50 mu.

[0020] At the beginning of May, water was injected to make the pond water level reach 50cm, and fermented chicken manure was used as organic fertilizer, and the daily dosage was 50kg / mu. Put it continuously for three days, 7-15 days after putting it, check the transparency of the pond, if the transparency is greater than 50cm, continue putting the fermented chicken manure for one day, and the amount of putting is 100kg / mu. The transparency is less than 30cm, and the water is changed normally, and 1 / 6 of the pond water body is changed at each spring tide. Add chlorella when fermented chicken manure is added. Chlorella can be commercially available or artificially cultivated with a concentration of> 10 million cells / ml, and the amount of 400 liters / mu.

[0021] From May to June, check the transparency of the pond every 20 days. If the transparency is greater than 40c...

Example Embodiment

[0025] Example two

[0026] In 2009, the sea cucumber farming pond in Nantangjia, Rushan, Shandong, covers an area of ​​80 mu.

[0027] At the beginning of May, water was injected to make the pond water level reach 70cm, and fermented chicken manure was put as organic fertilizer, and the daily dose was 100kg / mu. Put it continuously for three days, 7-15 days after putting it, check the transparency of the pond, if the transparency is greater than 50cm, continue putting fermented chicken manure for one day, and the amount of putting is 100kg / mu. The transparency is less than 30cm, and the water is changed normally, and 1 / 5 of the pond water body is changed at each spring tide. Add chlorella when fermented chicken manure is added. Chlorella can be commercially available or artificially cultivated with a concentration of> 10 million cells / ml, and the delivery volume is 900 liters / mu.

[0028] From May to June, check the transparency of the pond every 20 days. If the transparency is gre...

Abstract

The invention discloses a method of artificially restraining cladophora disaster from being generated in a sea cucumber aquaculture pool. The method of artificially restraining cladophora disaster from being generated in the sea cucumber aquaculture pool has the following advantages: firstly, nutritive salt content in pond water is gradually increased by putting in biofertilizer such as fermentation chicken manure, meanwhile, micro algae in the sea cucumber aquaculture pool is enabled to keep superiority by putting in chlorella vulgaris; secondly, through mass propagation of floating algae, transparency of the pond water is reduced, sunlight can not shine into the bottom of a sea, the cladophora can not acquire enough sunlight so that the cladophora can not grow; the method of artificially restraining cladophora disaster from generating in the sea cucumber aquaculture pool is a full-biological method, free of environment pollution and harmless to aquaculture animals. Due to the fact that after the floating micro algae dies and subsides, the floating micro algae serve as bait of aquaculture sea cucumbers. The method of artificially restraining cladophora disaster from being generated in the sea cucumber aquaculture pool has the advantages of being green, environment-friendly and circulatory. Therefore, the method of artificially restraining cladophora disaster from being generated in the sea cucumber aquaculture pool has various advantages, particularly suitable for popularization and application in the field and broad in market prospect.

Description

technical field [0001] The invention relates to a method for suppressing sea cucumber cultivation diseases, in particular to a method for artificially suppressing the occurrence of bristle algae disasters in sea cucumber cultivation ponds. Background technique [0002] Imitation sea cucumber ( Apostichopus japonicus) , also known as sea cucumber, sea cucumber, is an important species of mariculture in my country. my country's japonicus breeding industry has developed rapidly from small to large. As of 2008, the area of ​​sea cucumber cultivation in my country's coastal areas has reached 1 million mu, with an output value of nearly 20 billion yuan, accounting for nearly 1 / 3 of the output value of the region's mariculture industry, and has become a regional pillar industry. Pond culture is the main production mode of sea cucumber artificial culture in my country (Chang Yaqing, 2005). It is also the basis for the development of sea cucumber industry. However, due to the rap...
