Evaluation of strobe lights to reduce turbine entrainment of juvenile steelhead (Oncorhynchus mykiss) at Cowlitz Falls Dam, Washington Evaluation of strobe lights to reduce turbine entrainment of juvenile steelhead (Oncorhynchus mykiss) at Cowlitz Falls Dam, Washington
We conducted a radiotelemetry evaluation to determine if strobe lights could be used to decrease turbine entrainment of juvenile steelhead (Oncorhynchus mykiss) at Cowlitz Falls Dam, Washington. We found that radio-tagged juvenile steelhead approached and entered two spillbays (one lighted, one unlighted) in equal proportions. However, the presence of strobe lights was associated with...

Behavior and passage of juvenile salmonids during evaluation of a new fish screen at Cowlitz Falls Dam, 2006 Behavior and passage of juvenile salmonids during evaluation of a new fish screen at Cowlitz Falls Dam, 2006
In spring of 2006, Tacoma Power installed a new fish screen at the Cowlitz Falls Project (CFP) with the purpose of improving the collection of anadromous juvenile fish for downstream transport. The new fish screen was placed between the upstream baffle panels and the fish gates and flume system that lead to the Cowlitz Falls Fish Facility. We initiated a radio telemetry evaluation of the...

Fishing is an important part of Oregon's culture. The Western Fisheries Research Center (WFRC) has been conducting research in Oregon for many years to provide information that can be used by managers to help keep fish and other parts of the ecosystem healthy. Below are examples of some of WFRC's studies.

Nonlethal gill biopsy does not affect juvenile chinook salmon implanted with radio transmitters Nonlethal gill biopsy does not affect juvenile chinook salmon implanted with radio transmitters
Using gastric and surgical transmitter implantation, we compared radio-tagged juvenile chinook salmon Oncorhynchus tshawytscha (T(O)) with tagged fish also having a gill biopsy (T(B)) to determine biopsy effects on fish implanted with radio transmitters. We found no evidence during the 21-d period to suggest that a gill biopsy reduced survival, growth, or gross condition of the tagged...

Some preliminary findings on the nutritional status of the Hawaiian spiny lobster (Panulirus marginatus) Some preliminary findings on the nutritional status of the Hawaiian spiny lobster (Panulirus marginatus)
Data on the nutritional status of spiny lobster (Panulirus marginatus) were collected on the commercial trapping grounds of Necker Bank, Northwestern Hawaiian Islands, in the summers of 1991, 1994, and 1995. Glycogen levels measured in abdominal tissue of intermolt males were used as an index of nutritional health of the field population. The range of glycogen sampled from wild lobster...

Growth and physiological responses to surgical and gastric radio transmitter implantation techniques in subyearling chinook salmon (Oncorhynchus tshawytscha) Growth and physiological responses to surgical and gastric radio transmitter implantation techniques in subyearling chinook salmon (Oncorhynchus tshawytscha)
We examined the effects of surgical and gastric transmitter implantation techniques on the growth, general physiology and behavior of 230 subyearling chinook salmon (Oncorhynchus tshawytscha, Walbaum) (100 mm-154 mm fork length). The transmitter weighed 1.3 g in air (0.9 g in water) and comprised, on average, 6% of the body weight of the fish (in air). Individuals were randomly assigned...
