Developing Cost-Effective Ways to Produce a Pheromone that Controls Sea Lamprey

Previous Sea Grant-supported work led to the discovery of a  migratory pheromone that lures the invasive sea lamprey. This  project seeks to develop practical, cost-effective ways to produce a  major constituent of that pheromone. Sea lampreys are currently  controlled by a pesticide that sometimes kills other fish, so the  Great Lakes Fishery Commission is pursuing less toxic alternatives.   Pheromones (chemical signals that animals use to communicate) are  non-toxic and target specific species. Both male and female lampreys  rely on this pheromone to migrate into spawning streams. The  commission hopes to use synthetically produced pheromones to confuse  or lure lamprey into traps before they spawn. Field tests have  demonstrated that the pheromone can increase capture rates by six- fold in small streams.   The problem is that producing the pheromone is costly. Researchers  hope to develop a process to synthesize the most important part of  the pheromone (petromyzonamine disulfate) more efficiently so that  it can be produced in the relatively large quantities necessary to  sustain sea lamprey control programs.
