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 and treatment methods are all very limited in effect due to the limitation of more aspects, and the side effects are relatively large.
Although the chemical method is time-saving and labor-saving, it cannot be ruled out that the drug will have toxicity and long-term effects on sea cucumbers, and will destroy beneficial algae and biological provenance in the pond, thereby affecting the growth of sea cucumbers.

Embodiment 1

[0019] In 2009, the sea cucumber breeding pond in Huangguzui, Zhuanghe, with an area of ​​50 mu.

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

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

Embodiment 2

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

[0027] At the beginning of May, water was injected to make the water level of the pond reach 70 cm, and the fermented chicken manure was put in as organic fertilizer, and the daily amount was 100 kg / mu. Continuous feeding for three days, 7-15 days after feeding, check the transparency of the pond, if the transparency is greater than 50cm, continue feeding fermented chicken manure for one day, and the feeding amount is 100kg / mu. When the transparency is less than 30cm, change the water normally, and change 1 / 5 of the pond water at each spring tide. Add fermented chicken manure and throw chlorella at the same time. Chlorella can be commercially available or cultivated artificially. The concentration is >10 million cells / ml, and the dosage is 900 liters / mu.

[0028] From May to June, check the transparency of the pond every 20 days. If the transparency is greater than 40cm,...

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...
