Maine Fishing Landlocked Atlantic Salomon

by: Ronald Moody



Landlocked Salmon Atlantic Salmon are know only in the State of Maine. Some of the other names are Sebago Salmon or Quananiche and the scientific name is Salmo Salar. The average size is 16-18 inches and 1-2 pounds, but 3-5 pound fish are not uncommon. Adults are generally silvery wiyh a slightly forked tail and small x-shaped marking on the back and iper sides. Juvenile salmon have a dark red spot between each pair of parr marks. Mature males develop a kype or hooked jaw, during the spawning season.

Landlocked salmon are a freshwater form of the sea run Atlantic Salmon. Prior to 1868, landlocked salmon populations occurred in only four river basins in Maine, St. Croix including West Grand Lake in Washington County, the union, including Green Lake in Hancock County, the Penobscot, including Sebec Lake in Piscataquis, County, and the Presumpscot, including Sebago Lake in Cumberland County.

Today, landlocked salmon provide the primary fishery in 176 lakes comprising nearly 500,000 acres. They are present and provide incideatal fisheries in an additional 127 waters comprising about 160,000 acres. Maine supports one of the larges sport fisheries for this species in the world. Landlocked salmon also provide good fisheries in 44 rivers and streams totaling about 290 miles.

Hatchery stockings are needed to maintain fisheries in 127 lakes. These lakes do not sufficient amounts of suitable spawning and nursery areas to produce wild salmon. Without regular stockings, salmon in these lakes would disappear entirely, or their numbers would be very, very low. About 123,000 salmon were stocked annually in Maine lakes from 1996 to 2000.

Natural reproduction supports salmon fisheries in 49 lakes. These are lakes that have sufficient spawning and nursery habitat to produce enough salmon to support good fisheries. Most of these waters are located in western and northern Maine. Salmon spawn in lake outlets or inlets during the period from mid October to late November. Eggs are buried in gravel from 4-12 inches deep and remain there until hatching early the following spring.

Young salmon spend from 1 to 4 years in a stream environment prior to migrating to a lake. Recent studies in Maine show most wild salmon spend 2 years as stream dweelers. In wild salmon populations, most males spawn first at ages 3 and 4, although a few spawn at ages 1 and 2. Females usually spawn first at ages 4 and 5. Spawning runs of wild salmon may be composed of fish ranging in age from 1 to 10 but 3, 4 and 5 year old individuals make up the bulk of most runs. Landlocked salmon may be repeat spawners, but most fish observed on spawning runs are spawning for the first time. Salmon may spawn in consecutive or alternate years, some may spawn in consecutive years then skip a year, and some may skip 2 or 3 years between spawning.

Salmon populations sustained by natural reproduction often more older age fish those supported by stocking, wild salmon usually exhibit slower growth do hatchery salmon, so they reach legal size and harvested 1 or 2 years later. The oldest landlocked salmon on record in Maine was years old.

Rainbow smelts are the principal forage species for salmon in Maine lakes. Without adequate numbers of smelt, salmon growth and body conition will be poor, markedly reducing value as a sportfish. Maintain adequate numbers of smelt for forage is the most important element of salmon management in Maine. Extensive studies conducted in Maine clearly show that salmon growth rates, and consequently the size of fish available to anglers, is best in lakes with excellent water that do not have large populations of other smelt predators, particularly lake trout.

From 1996 to 2000 Maine open water anglers voluntarily released over 60% of their catch of legal salmon, ice anglers released about 25% of their legal salmon catch. Catch and release of salmon has improved fishing in many lakes, but in others it has resulted in depressed smelt populations and smaller salmon, because there are too many salmon. Maine fishery biologists have responded by reducing stocking rates by implementing fishing regulations designed to restore a reasonable balance between numbers of smelts and salmon.

Hatchery salmon generally provide fisheries for larger fish than do wild salmon because the number of smelt predators can be strictly controlled. Therefore, precise management for particular types of fisheries, such as those emphasizing trophy fish, is usually best achieved with hatchery stocks rather than wild stocks.

From 1996 to 2000, the average size of salmon harvested from all Maine lakes was 17.4 inches and 1.7 pounds, the largest since department fishery biologists began conducting scientific creel surveys in the 1950’s.
