Stocking Rate and the Growth and Yield of Landlocked Atlantic Salmon at Long Pond, Maine

Abstract Four groups of age-I+ fall yearling Atlantic salmon (Salmo salar) were planted at Long Pond, Mount Desert Island, Maine between 1952 and 1969 to evaluate relationships between stocking rate, growth, and yield, the latter determined from randomly stratified creel censuses. There were significant inverse linear relationships between both stocking rate and growth and stocking rate and yield. Size at planting was not related to yield. Atlantic salmon recoveries averaged 6% for all plantings combined but ranged up to 45% for one lot. Mean size of Atlantic salmon caught from the different groups ranged from 41 to 45 cm and 0.6 to 0.9 kg. Mean annual effort expended in harvesting Atlantic salmon from the different cohorts ranged from 696 to 808 angler trips per year (summer and winter effort combined).
