thumb_purse_seine_yc200a.png- revolutionary supporting device for Purse Seining

Basic components of this system are high quality strobe flash light and foaming fluorescent dyestuff and this combination generates luminous screen by diffused reflection.  
( Patent No.2907817 Japan )

Description

When purse seining, a lot of fish can escape through the open space between both ends of the net while winding up tow/purse lines after surrounding a shoal of fish (refer to the following figure left).

The Fish Intimidation System serves as unique and very practical means to solve that problem. The basic components of the system is a high quality strobe flash light and foaming fluorescent dyestuff.

Throw the YC-200A main unit and foaming fluorescent dyestuff into the open space between both ends of the net and/or bottom of the net while winding up tow/purse lines at a timely manner, then the strobe flash light and the dyestuff generates a huge green luminous screen.

The screen scares the fishes and it remains in the net. (refer to the following figure right).
