Description

  TECHNICAL FIELD The present invention relates to a method for washing and physiologically activating laver nets for controlling and preventing diseases caused by miscellaneous algae mixed with cultured laver nets and bacteria.

  When laying aquaculture laver nets in the sea, there are problems such as mixed algae and diseases caused by various germs, etc.Acid treatment is generally used as a method for controlling and preventing such algae and germs. Has been. As an example of a laver acid treatment agent, a solution obtained by adding an inorganic salt and an acid to seawater is disclosed (for example, see Patent Document 1). In addition, an acid treatment agent having a small pH change is disclosed by mixing a buffer compound containing no phosphorus in an organic acid with seawater (see, for example, Patent Document 2). Also disclosed is an algicidal fungicide that simultaneously eliminates and prevents Aonori diatom and red rot fungi with organic acids such as lactic acid and citric acid (see, for example, Patent Document 3). However, both of these damage the nori leaf bodies by strong acids and hinder the growth of nori. As a result, dry seaweed becomes hard and inhibits the taste. Leaf bodies damaged by cryopreservation have reduced physiological activity, lost survival competition with miscellaneous algae, and are more susceptible to infection with bacteria, resulting in red kusale disease, rod disease, and sumi nori. Reduce.

  In view of the above prior art, the problem to be solved by the present invention is to reduce the pollution load on the environment or not to discharge the pollution load at all. Another object of the present invention is to provide a conventional acid treatment agent having a reduced concentration to control and prevent miscellaneous algae and bacteria and to impart physiological activity to the laver leaf body. Another problem is that, after extermination of miscellaneous algae and germs, the laver leaf body is imparted with physiological activity to overcome the survival competition with the miscellaneous algae and miscellaneous fungi and to produce a soft and delicious dry laver. In addition to exterminating miscellaneous algae and germs at the time of application of the frozen laver net, it is also possible to exterminate miscellaneous algae and germs and impart physiological activity to the laver leaf body during the growth of the laver leaf body. Let it be an issue. Another object is to contribute to environmental purification.

  In order to solve the above-mentioned problems, the present invention is characterized in that, in the first invention, cultured algae nets are immersed in a liquid tank in which the concentrations of various conventional acid treatment agents are kept to a minimum, so that algae, bacteria, etc. After weakening, a microbubble-containing air-water two-phase flow is blown with a microbubble generator to eliminate and prevent the weakened algae and bacteria and activate the nori leaves with the bioactive function of the microbubbles. .

  In addition, it is not necessary to increase the concentration of the acid treatment agent to kill all kinds of algae and bacteria, and from the nori leaves, by removing the algae and bacteria, the adhering to the nori leaves As the quantity of miscellaneous algae and germs decreases, the laver leaf bodies weakened by frozen storage or disease gradually recover and are hardly affected by the algae and germs that are permanently present in the sea of the natural environment. It becomes a nori leaf body (and so on).

  Moreover, in the second invention, the cultured laver net is immersed in a water tank that stores seawater, and a microbubble-containing air-water two-phase flow is blown with a microbubble generator to control and prevent seaweeds and bacteria. At the same time, the nodules are activated by the bioactive function of the microbubbles.

  In the third invention, the cultured laver net is immersed in a water tank in which seawater is stored, pre-washed with a physical washing device such as brushing or ultrasonic washing device, and then microbubble-containing gas is contained in the microbubble generator. A two-phase flow of water is blown to exterminate and prevent seaweeds and bacteria, and activate the laver leaf bodies with the bioactive function of the microbubbles.

  In addition, in the fourth invention, the cultured laver net is immersed in a water tank in which seawater is stored, and a microbubble-containing air-water two-phase flow is blown with a microbubble generator to eliminate and prevent seaweeds and bacteria. In addition, the cultured laver net that has activated the nori leaf bodies by the bioactive function of the microbubbles is cultivated by being embedded in seawater, and is floated in the seawater of the aquaculture environment at the time of the cultivation or periodically. New seaweeds and bacteria that are attached to the cultured laver leaves are controlled and prevented, and the laver leaves are physiologically activated and cultured.

  Since the present invention is configured as described above, the following effects can be obtained.

In the first invention, compared with the case where various conventional acid treatment agents are used in a high concentration state, the load on organic matter and eutrophication is reduced, and the reduction of anoxic water mass layer and the reduction of species are reduced. There is also an effect of suppressing the above.

  In addition, before the seaweed net is put into the sea, it is immersed in dilute seawater containing various conventional acid treatment agents, and after weakening seaweeds and bacteria, etc., a microbubble-containing air-water two-phase Blowing a flow, the cleaning function of the microbubbles, the extermination of the weakened seaweeds and bacteria, the prevention effect is enhanced and the physiological function of the microbubbles activates the physiological function of the laver leaf body, It has the effect of promoting the healthy growth of nori leaves.

  Further, in the second invention, the conventional acid treatment agent is not used at all, and a microbubble-containing air-water two-phase flow is blown with a microbubble generator, and the washing function of the microbubbles enables seaweeds and bacteria. No organic matter load or eutrophic load is discharged into the environmental sea at all, so it is effective in the removal and prevention of environmentally friendly seaweeds and bacteria. It activates the physiological function of the leaf body and exerts the effect of promoting healthy growth of the laver leaf body.

  In addition, since no acid treatment agent is used, the laver leaves are not damaged, so that an effect of growing a soft and delicious laver is produced.

  In the third aspect of the invention, the conventional various acid treatment agents are not used at all. First, seaweeds and bacteria are preliminarily exterminated by physical means, and after prevention, two microbubble-containing air and water are produced by a microbubble generator. Blowing a phase flow, the microbubble cleaning function removes the rest of the seaweeds and bacteria, etc., without discharging organic load and eutrophic load at all, by the physiological activation function of the microbubble, It activates the physiological function of the laver leaf body and exerts the effect of promoting the healthy growth of the laver leaf body.

  In the fourth invention, a microbubble-containing air-water two-phase flow is blown into the seawater that is cultivated with a laver net, and floats in the seawater in the aquaculture environment. Eliminates and prevents new seaweeds and bacteria from adhering to the laver leaf body and cultivates the nori leaf body through physiological activation, thus increasing the yield of healthy laver and increasing the aquaculture income Play.

  In addition, the microbubble sterilization function eliminates the phytoplankton causing red tide and combines oxygen produced by photosynthesis of seaweed with oxygen contained in microbubbles to supply oxygen to the environmental seawater. It becomes the environment, the growth of bivalves and the like is promoted, and the organic substance is decomposed by the bivalves and the like, becomes a nutrient source for laver, and has the effect of promoting the growth of laver.
