Abstract
Official abstract text for this publication.
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.
First claim
Opening claim text (preview).
The invention claimed is: 1. A method of stopping a larva of Pteriomorphia in a settlement stage from swimming or crawling in water, comprising the step of: irradiating light in a wavelength range including 400 to 550 nm to the larva in the settlement stage, wherein the light consists of a part of the visible spectrum and does not comprise the entire visible spectrum and wherein the light is not a laser beam. 2. A method of stopping a larva of Pteriomorphia in a settlement stage from swimming or crawling in water, comprising the step of: irradiating light in a wavelength range including 400 to 440 nm to the larva in the settlement stage, wherein the light consists of a part of the visible spectrum and does not comprise the entire visible spectrum and wherein the light is not a laser beam. 3. The method according to claim 1 or 2 , wherein the water is seawater. 4. The method according to claim 3 , wherein the sessile invertebrate is a mussel or an oyster. 5. The method according to claim 4 , wherein the larva in the settlement stage is a pediveliger or a plantigrade of Mytilus galloprovincialis or Perna viridis. 6. The method according to claim 3 , wherein the larva in the settlement stage is a pediveliger or a plantigrade of Mytilus galloprovincialis or Perna viridis. 7. The method according to claim 1 or 2 , wherein the sessile invertebrate is a mussel or an oyster. 8. The method according to claim 7 , wherein the larva in the settlement stage is a pediveliger or a plantigrade of Mytilus galloprovincialis or Perna viridis. 9. The method according to claim 1 or 2 , wherein the larva in the settlement stage is a pediveliger or a plantigrade of Mytilus galloprovincialis or Perna viridis. 10. The method according to claim 1 or 2 , wherein the intensity of the irradiated light is 200 to 2,000 W/m 2 .
