ようになした海藻等除去方法に関するものである。DETAILED DESCRIPTION OF THE INVENTION In order to remove seaweed, etc. that have adhered to fishing nets used for fishing, such as fixed nets and aquaculture nets, the present invention involves attaching a brush to the fishing net that is set in the sea. This invention relates to a method for removing seaweed, etc., in which seaweed, etc. stuck to a fishing net is brushed off by shaking a brush under the action of seawater.
海中へ網をセットしておくと、−週間程度で網に海藻等
が耐着し、その結果、網目が塞がって網の内側と外側と
の海水の流通が悪くなり、内側の海水がよごれたり酸累
不足になって魚の捕獲ができなくなってしまい、又、養
殖の場合には魚が死滅してしまう。If you set a net in the sea, seaweed etc. will adhere to the net in about a week, and as a result, the net will become clogged and the circulation of seawater between the inside and outside of the net will become poor, causing the seawater inside to get dirty. Due to the lack of acid accumulation, it becomes impossible to catch fish, and in the case of aquaculture, the fish die.
従来、上記を防止する手段として、一定時期に別の網と
交換して、その目的を達成してきたが、この網の交換作
業には多くの人手と労力を要し、人手不足の昨今におい
ては、このような網の交換作業を繰返して行なうことは
困難になった。Conventionally, as a means to prevent the above, the goal was achieved by replacing the net with another one at a certain period of time, but replacing the net requires a lot of manpower and effort, and in recent years due to the lack of manpower, It has become difficult to repeatedly perform such net replacement work.
そこで、近時に至り、網を交換することなく、海中にセ
ットしたま〜、この網に耐着している海藻等を除去する
方法が試みられ、各種の装置が開発されている。Therefore, in recent years, attempts have been made to remove seaweed and the like that cling to nets while they are set in the sea without replacing the nets, and various devices have been developed.

受けて揺れ動ご（ようになっている。Hereinafter, the present invention will be described in detail based on illustrated embodiments. First, the configuration etc. of an example of an apparatus used to carry out the method of the present invention will be explained. FIG. 7 is a perspective view showing an embodiment of a seaweed etc. removal device used for carrying out the method of the present invention, 21
- The figure is a side view of the same, and FIG. 3 is a plan view of the same. In these figures, 1.2.3.4 are brushes formed to the desired length, each brush 1.2.3.4 being a fiber rope 5, for example.
The length of the brush 1.2.3.4 is determined by the fishing net N (
The appropriate length should be determined according to the width (height) of the blade. A float 7 is attached to the upper end of the rope 5 of each brush 1.2.3.4, and a sinker 8 is attached to the lower end. , 9b, etc., and the brushes 1 and 3 and 2 and 4 are connected by a connecting rod 1-11Ob, etc. of a desired length. The seaweed removal device Xa defined as described above hangs down and floats in the sea, and oscillates under the action of seawater such as waves and currents.

成して構成しである。The present invention uses the seaweed, etc. removal device configured as described above to remove seaweed, etc. that has adhered to fishing nets N such as fixed nets and aquaculture nets.Next, the seaweed, etc. removal method of the present invention will be explained. do. Figure 19 is a perspective view of the state in which the method of the present invention is being carried out. The figure is a side view of the same, and the figure g is a front view of the same. As shown in these figures, fishing nets N such as fixed nets and aquaculture nets have a fishing net between the float chain 11 at the upper end and the sinker chain 12 at the lower end. It consists of 13 organized.

る。Therefore, the seaweed removal device a described above is set in the sea, and the brushes 1 and 2 and 3 and 4 are suspended from the fishing net N so as to sandwich the fishing net N, and the appropriate part of the seaweed removal device a is The connecting links 9a and 9b in the embodiment are tied and fixed to the float link 11 using strings 14 or the like. As a result, each brush 1.2.3.4 is arranged opposite to each other so as to be able to swing freely. Therefore, each brush 1, 2, 3, 4 swings as shown by the chain line in Figures 1 and 1-6 due to the effects of seawater such as waves and tidal currents.
Seaweed, etc. that are resistant to 3 are removed. Then, after an appropriate time or date and time have elapsed, move the installation position of the seaweed etc. removal device a to remove sea noise etc. in the same way as above, and in this way change the installation position of the removal device a appropriately one by one to remove the action of the seawater. This removes seaweed etc. by shaking the brush.
