ORLAND, Maine — Maine’s fish and wildlife conservation efforts will get a boost from federal stimulus funds through the U.S. Department of the Interior.

Maine will receive $4.3 million from the U.S. Fish and Wildlife Service, part of a $280 million investment from the federal stimulus package that will fund more than 800 projects nationwide, according to a recent press release.

The two national fish hatcheries in Hancock County will receive more than $1.5 million, mainly targeting deferred maintenance projects at the two facilities.

The Green Lake National Fish Hatchery in Ellsworth will receive $839,000 that will be used to replace the facility’s fish production water alarm system, replace translucent wall panels, restore a highly inefficient UV disinfection system, replace five highly inefficient Modine heaters in the tank room, and replace 72 deteriorated water inlet lines and valves to the facility’s 30-foot diameter fish production ponds.

The Craig Brook National Fish Hatchery in Orland will receive $723,000 that will be used to replace the roof on the receiving building, install new personnel doors to comply with safety codes, replace the existing outdated water treatment plant generator and repair the existing ventilation-exhaust system.

Funds also will be used for fish habitat restoration. The Maine Fishery Resources Office will receive $75,000 for fish passage restoration projects.

Two wildlife centers also will receive funding through the stimulus funds. The Rachel Carson National Wildlife Refuge in Wells will get $748,000 that will be used to remove and replace seasonal housing, to install a geothermal heat pump, replace observation platforms, and restore hiking trails.

The Moosehorn National Wildlife Reserve in Calais will receive $71,000 that will be used to replace the water control structure on the Goodall Heath trail.
