Method for prevention and treatment of production of holothurian aquaculture pond cladophora disasters through synergia of multiple living beings

Abstract

The invention discloses a method for prevention and treatment of production of holothurian aquaculture pond cladophora disasters through synergia of multiple living beings. According to the method, synergistic effects of three kinds of living beings are utilized, unicellular floating miniature algas are cultivated in rich water, the illumination transmission degree is controlled through increasing of density of the unicellular floating miniature algas, transmittance of light of pond water can be reduced through gulfweed simultaneously, benthic cladophora cannot receive illumination, and therefore the purpose that growth of the cladophora is controlled is achieved. By means of the ingestion function of rock worms, a small amount of cladophora growing at the pond bottom is eliminated. The method is a complete living being method, does not cause pollution to the environment, and does not injure aquaculture animals. Meanwhile, the floating algas can serve as bait of holothurian aquaculture after dying and sinking. The method has the advantages of being environment-friendly and capable of achieving circulation. The method provides a brand new thought way for prevention and treatment of the cladophora, particularly the cladophora is eliminated through biological competitive inhibition and biological uptake, and therefore a new field is created for prevention and treatment of similar harmful algas.

Description

technical field [0001] The invention relates to a method for preventing and treating diseases of sea cucumber cultivation, in particular to a method for synergistically preventing and controlling 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 i...

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.
