An Evaluation of Lake Trout Spawning Habitat Characteristics and Methods for Their Detection (Fitzsimons, 1994)
1 January 1994Report
This technical report evaluates lake trout spawning habitat characteristics in inland and Great Lakes environments, synthesizing data from verified spawning sites to develop criteria for identifying new spawning locations. The study identifies physical and hydrological factors (multi-layered cobble substrates, depth-related to lake size, slope inclination, currents) as primary determinants of spawning site selection, and recommends buried egg entrapment gear as superior to surface methods for detecting spawning habitat.

Effects of Instream Mining for Granular Materials on Grayling Habitat in Northern Alaska (DenBeste & McCart, 1986)
~1986Report
Approximate date — inferred from filename
This study compared stream habitats and grayling populations in reaches affected by instream granular materials mining during Trans Alaska Oil Pipeline construction (1974-1977) with undisturbed control reaches in five northern Alaskan streams, finding that mining typically reduced habitat quality, fish size, and biomass, with effects persisting 4-9 years after disturbance, though one exceptional case showed improved juvenile grayling habitat from increased depth.

Relative Suitability of Use Functions for Juvenile and Adult Grayling (Thymallus arcticus) in Streams in Northern Alaska (DenBeste & McCart, 1986)
~1986Report
Approximate date — inferred from filename
This research paper presents relative suitability-of-use functions for juvenile and adult Arctic grayling (Thymallus arcticus) in 23 streams across northern Alaska, using depth, velocity, and substrate type as key habitat parameters. The study demonstrates that juvenile grayling prefer depths of 0.65 m with zero velocity and fine substrates, while adults prefer greater depths of 0.80 m, with both groups showing clear correlations between habitat suitability function values and fish occupancy and density.

The Susceptibility of Salmonid Fish to Poisons Under Estuarine Conditions (Herbert & Wakeford, 1964 to 1965)
2 November 1964Report
Two experimental studies comparing the susceptibility of Atlantic salmon smolts and yearling rainbow trout to zinc sulphate and ammonium chloride across varying salinity levels from fresh water to full-strength sea water. Results show resistance to both poisons increases with salinity up to 30–40% sea water, with salmon smolts consistently more susceptible than trout, and tolerance differences attributable to gill permeability and osmotic effects.
