Stock assessment of Arctic grayling in these systems was accomplished through estimation of population abundance, age composition, and size composition.
In three river systems and one lake system, population abundance was estimated by mark-recapture experiments. Estimates of Arctic grayling abundance, survival, and recruitment have been calculated for to the present.
These estimates and age, size, and sex composition data, are used to describe the status of the Fielding Lake Arctic grayling stock. Stock Assessment Goals and Objectives. The Alaska Department of Fish and Game and the U.S.

Unlike most salmonids, grayling do not construct any sort of nest but spawn directly over gravel or rocky areas of smaller streams and tributaries (Behnke ).
