The primary cause for this decline has been a substantial increase in age-0 natural mortality rates, which peaked at an instantaneous rate of around 6.3 in the late 2000s, although fishing mortality rates have also been quite high. Initially, declines in survival were associated with increases ...
Michigan (Heinrich et al.1980). A similar shift in the sex ratio in Lake Huron began before treatment reduced larval density, and was as low as 31 % males by 1975, likely because of environmental conditions and extremely low abundance of lake trout in the 1950s (Purvis1979; Heinrich et a...
