520 |a"Commercial fishing for whitefish in Great Slave Lake has been proceeding since 1945. Its competitor, the sturgeon sucker, has been scarcely exploited by this fishery. A two-year study of the suckers was begun in the summer of 1950 to learn something of the general biology of the species and to determine if the removal of whitefish had changed their rate of growth or abundance. Sampling was done with standardized nets and young fish were caught by seining. Some 1100 suckers were examined. Data concerning growth in length and weight are provided. Mortality rate and growth coefficient are discussed. Spawning habits are examined. The sucker is found to spawn in the spring in streams. Age of spawning fish, number of eggs and condition are discussed"--Abstract.
