The effects of electroshock on immune function and disease progression in juvenile spring chinook salmon (Oncorhynchus tshawytscha)

Creator:: VanderKooi, Scott P.
Abstract:: Electrofishing is a sampling tool commonly used by fisheries researchers. While much is known about the effects of electroshock on fish physiology, consequences to the immune system and disease progression have not received attention. To understand the effects of electroshock on immune function we undertook a comparison of electroshock and...

Abstract:: Reestablishing native perennial vegetation in annual grass-invaded rangelands is critical to restoring ecosystems, especially following wildfires. Controlling invasive annual grasses is essential to increasing revegetation success; however, pre-emergent herbicides used to control annual grasses prohibit immediate seeding due to non-target herbicide damage. Thus, seeding is often delayed one year following...

Territorial behavior in juvenile steelhead trout (Oncorhynchus mykiss) : how redside shiner (Richardsonius balteatus) influence intraspecific interactions

Creator:: Tinus, Craig A.
Abstract:: Juvenile steelhead are known to associate with shiner groups, though they also compete for food. Steelhead form dominance hierarchies within cohorts and aggressively defend feeding territories against all other fish. This study focused on the differential effect of shiner competition on steelhead of different social standing. Survival of subordinate juvenile...
