CONT: The population status of Walleye of Tathlina Lake appears to have improved between 2001 and 2007. The mean size (length and weight) of Walleye and age of Walleye has increased, while the increase in catch-per-unit effort of and proportion of Walleye in the total catch suggests an increase in Walleye biomass in the lake. The presence of the strong 1997 year class that reached sexual maturity in 2003 was left to spawn multiple times without considerable harvest has likely helped improve the status of the population.
