Biochemical and physiological indicators of behavioral impairment in salmonids exposed to chlorpyrifos and copper

Creator:: Sandahl, Jason
Abstract:: The purpose of this work was to determine if environmentally-relevant concentrations of chlorpyrifos and copper, two commonly detected chemicals in Western surface waters, can negatively impact the biological health of salmonids. Both compounds are highly neurotoxic to fish, but each with distinct biological target sites and mechanisms of action. We...

Continuous monitoring and modeling to assess pesticide exposure in critical habitat for Pacific salmonids

Creator:: Janney, Philip K.
Abstract:: Pacific Northwest and California freshwater resources are key elements in the life history and ecology of Pacific salmon and steelhead listed as threatened or endangered under the Endangered Species Act. Risk to listed Pacific salmonid species can be assessed by evaluating the spatial and temporal co-occurrence of salmonid species at...

Early development of the endocrine system in salmonids : regulation of sex differentiation and ontogeny of the stress response

Creator:: Floyd, Donald J.
Abstract:: Sex steroids, follicle stimulating hormone (FSH), luteinizing hormone (LH) and gonadotropin releasing hormone (GnRH) were measured in monosex and mixed sex populations of rainbow trout during early development. Steroids declined following fertilization, increased at hatch, then fell and remained constant thereafter. Trends toward differences in steroids between males and females...

Cytophaga psychrophila, the causative agent of bacterial cold-water disease in salmonid fish

Creator:: Holt, Richard Allen
Abstract:: Morphological, cultural, biochemical and serological characteristics of 33 bacterial strains, thought to be similar to Cytophaga psychrophila, the causative agent of bacterial cold-water disease were compared. Bacterial strains identified as C. psychrophila were obtained from diseased salmonids collected at widely separated geographic locations, and from fish with pathological signs different...

The response of nitrifying bacteria to treatments of N-Serve and Roundup in continuous-flow soil columns

Creator:: Rhodes, Albert N.
Abstract:: This study examined the effects of Roundup [N-(phosphonomethyl) glycine] and N-Serve [2-chloro-6- (trichloromethyl) pyridine] on nitrifying organisms in static batch, perfusion soil columns, and a new continuous-flow soil column system. The continuous-flow method is new to nitrification studies and was shown to produce greater nitrifier activity than either static batch...
