Q: What is Maine's management philosophy for Arctic charr Salvelinus alpinus?

A: The management of charr in Maine is guided by goals and objectives formulated and developed by a periodic planning process. The latest revision of the Arctic charr plan and the species assessment was in 2001. Some of the guiding principles of the plan are 1) use of conservative fishery regulations, 2) habitat quality protection, and 3) conservation of the unique gene pool present in Maine.

Maine’s management philosophy is a conservative one toward the species, that is, maintaining and conserving each current population is a high priority. Sport fishery regulations that adequately protect the species from overharvest, excessive hooking mortality, and the accidental or unauthorized introductions of new fish species, those that are invasive to the charr water, are in place on all waters in Maine. The plan identified that invasive species remain a serious threat for populations in Maine. While cumulative impacts of watershed uses is a concern for habitat, no issue currently takes higher precedence than the spread of invasive species and their direct effects on charr population viability.

Arctic charr in Maine represent a very rare and unique resource represented by the only populations in the lower forty-eight States. Furthermore, recent genetic work shows that our populations are genetically isolated, representing unique gene pools, and that many of them have adapted specifically to the available forage base. For these reasons, we have adopted a management plan that warrants protection for each individual population because compromising or losing even one would mean an irretrievable loss of the genetic makeup for the species in Maine.
