Technical Field

The invention relates to the technical field of shellfish culture, in particular to a shellfish culture cage and a method for removing fouling organisms of the shellfish culture cage.

Background

Pinotadamantatensis Dunker grows in subtropical sea areas, is mainly distributed in coastal areas such as Guangdong, Guangxi, Hainan and Japan in China, and is the most main species for producing seawater artificial cultured pearls in the world at present. The pearl yield of the pinctada martensii in China accounts for more than 95% of the whole seawater pearl yield and occupies the leading position of seawater pearl production, and the pinctada martensii seedlings are collected from a seedling collector and then are subpackaged in a seedling cage to be hung in the sea. The meshes of the seedling cages are smaller than those of seedlings in each period, and the net clothes need to be washed frequently and replaced regularly. The seedling is about half a year from young seedling, middle seedling to big seedling. The growing period is started when the big seedlings begin to mature. The cages of the female shellfish in the growing period also need to be cleaned and replaced frequently, the diseases and the insect pests are prevented and the attack of typhoon, fresh water and low temperature is avoided. The cage for culturing the pinctada martensii is mainly a traditional conical cage and a traditional cylindrical cage, the pinctada martensii can be invaded by fouling organisms all the year round, and particularly, a large amount of barnacles, limests, sponges, coiled pipe worms and the like which are attached to a net cage and pinctada martensii bodies in high-temperature seasons influence the exchange of water flow between the cultured net cage and the outside, interfere the opening and closing of shellfish shells, and seriously influence the growth of certain fouling organisms such as talent girls which can chisel the shells of the shellfish to cause bacterial infection and shellfish diseases.

The main current methods for preventing and removing shellfish fouling organisms are 1. physical methods: such as high-pressure water gun washing, drying, fresh water bath, controlled combustion and the like, but the methods are time-consuming and labor-consuming, have great damage to the shellfish and have little effect on the talent and girl which can invade the fouling organisms of the shells; 2. the chemical method comprises the following steps: it is common to treat aquaculture nets with chemicals, such as tributyltin (TBT), organo-aluminum, organo-arsenic, copper compounds, etc., but studies have shown that marine organisms are also affected by the toxicity of antifouling materials, and TBT coatings are currently being banned by the international maritime organization on a whole.

However, a large amount of manpower and material resources are consumed for removing fouling organisms in the pinctada martensii cultivation process, and the traditional physical and chemical methods can damage the cultivated pinctada martensii and pollute the cultivated water area.

Therefore, the method for providing the cultured shellfish cage with good use effect and removing the fouling organisms of the cultured shellfish cage become important technical problems to be solved by the technical personnel in the field.
