Relative densities of Lahontan cutthroat trout (clear bars) and tui chub (hatched bars) by depth and season in relation to bottom temperatures (solid line) and dissolved oxygen (dotted line). Temperatures at depths greater than 61 m in Pyramid Lake were less than 7 °C during all seasons; cutthroat trout densities were likewise at a minimum at these depths during all seasons. The absence of light in the profundal zone may also limit fish distribution, since trout are sight-feeders. The absence of illumina- tion also affects thyroid metabolism which indirectly affects growth patterns (Lagler et al. 1962). Since a small proportion of the trout catch was taken in this.
