Abstract
The present invention relates to the discovery of a new bacteria of the genus Alteromonas which has been found to attract oyster larvae by the production of compounds involved in melanin synthesis. More specifically, the present invention contemplates a method for inducing the settlement and metamorphosis of Crassostrea virginica larvae by induction with certain metabolic substances produced by the present bacteria and its altered variants. Furthermore, the present invention is directed to other and derivative metabolic products which can be employed for their desired utility and application. In accordance with the present invention, it has been discovered that ammonia (NH.sub.3) initiates settlement and metamorphosis of the oyster larvae in the same manner as the natural phenomena.
