Selective lampricide a better option?
Selective destruction of certain lamprey subpopulations may be more effective than trying to destroy entire populations of the invaders. A new approach to lamprey control may both save money and eventually become more effective than current efforts of lampricide in the Great Lakes area.
Gretchen J.A. Hansen and Michael Jones of Michigan State University have developed a model to determine the efficacy of targeting streams connected to the Great Lakes for lampricide and control of the sea lamprey population. This model targets streams with large numbers of the young form of the invader. By targeting these streams rather than the lamprey population at large, Hansen and Jones calculate that the effect on the population is the same for less money. With more resources and time, the team claims that the fight against lampreys can become more efficient as money that would be used for general lampricide can be spent to more accurately target lampreys for selective destruction.
