The present invention provides methods of stopping a larva of a sessile invertebrate in a settlement stage from swimming or crawling in water, by means of irradiating violet light having a wavelength range of 400 to 550 nm to the larva in the settlement stage of the sessile invertebrate.

Method of stopping larva from swimming or crawling

The present invention provides a method of stopping larvae of sessile invertebrates in the settlement stage from swimming or crawling in water, by irradiating light comprising the spectrum of 409 to 412 nm and a part of 400 to 440 nm, to the larvae in the settlement stage.

Method for stopping swimming or crawling of adhesion-stage larvae

The present invention provides a method of killing larvae of sessile invertebrates in the settlement stage in water, comprising the step of irradiating light comprising the spectrum of 409 to 412 nm, to the larvae in the settlement stage.

Method for killing Pteriomorphia and barnacles using light irradiation

The present invention is a method of preventing settlement of a sessile organism on a structure in water, including irradiating light comprising the spectrum of 409 to 412 nm to the structure where settlement of the sessile organism is prevented.

Method for preventing settlement of sessile organisms

The present invention provides a method of suppressing larvae of barnacles in the settlement stage from settling on a substrate in water by irradiating light comprising the spectrum of 409 to 412 nm and a part of 400 to 460 nm to larvae of barnacles in the settlement stage in a direction from the substrate to the larvae of barnacles in the settlement stage.
