Summary, Etc. Note: |
Abstract: The starfish (Asterias forbesi Desor) is one of the most destructive enemies of shellfish on the Atlantic coast of North America, the extent of its damange to the oyster industry of Long Island Sound alone being estimated at $500,000 a year. Efforts to eradicate the pest, though made for at least a century, have been largely unavailing. |

Abstract: The method of combating starfish presented here suggests the use of quicklime, the destructive effect of which is produced by direct contact. Particles of the chemical spread over oyster beds quickly sink to the bottom, and, falling on the starfish, are imbedded in the delicate skin. The caustic action of slaking lime disintegrates the membrane, and the lesions rapidly increase in size. After several days the wounds penetrate the body wall and expose the internal organs. Death usually follows in a short time. |

Abstract: Once spread over the oyster beds, the lime retains its effectiveness for some time. Starfish not hit directly by the descending particles will eventually come into contact with them when crawling along the bottom. In the course of time their lower surfaces become affected and disintegration will begin. The cheapness of lime, the simplicity of its application, and its comparative harmlessness to oysters and many other commercial species all indicate that it is a practical weapon for use against the inroads of starfish on oyster beds. |
