1992 |
A study to evaluate rearing chinook salmon and steelhead in standard and oxygen supplemented raceways was initiated. |
1992 |
Hatchery monitoring of steelhead revealed severe caudal fin erosion and led to a reduction in rearing densities. |
1992 |
Fish health monitoring and evaluation began in the fall of 1991. This was the beginning of systematic documentation for pathogens and disease in the new Umatilla Hatcheries Oregon and Michigan raceways. |
1993 |
Body tagging was eliminated from the tagging and marking program because it was found to be too costly and time consuming to be useful as a mass mark.. |
1993 |
Determined that subyearling spring chinook had a more severe level of BKD than fall release group and some reduction in survival may be anticipated. |
1993 |
A sensitivity comparison was made between the direct fluorescent antibody test (DFAT) and the enzyme-linked immunosorbent assay for the detection of Rs. At subclinical infection levels the DFAT was found to be an unreliable indicator of infection. |
1994 |
More than 2.4 million fall chinook salmon were successfully marked with blank-wire tags to improve the detection of strays at Snake River dams. |
1994 |
Releases of subyearling spring chinook salmon were eliminated based on juvenile rearing evaluations. Growth and juvenile performance were significantly less than expected. |
1994 |
There were significantly higher moralities in Michigan raceways over that in Oregon raceways for the fall release fish, however no differences in mortality rates were found between upper, middle and lower Michigan raceways. |
1995 |
Measurements of ATPase showed that smolts reared in standard and high density raceways developed at similar rates, but data obtained did not provide additional information on the optimum release date. |
1995 |
Bacterial kidney disease was a significant infectious disease in juvenile spring chinook salmon reared at Umatilla Hatchery. This was a direct correlation to the severity of infection in the female broodstock. |
1995 |
There was no convincing evidence for horizontal transmission of Rs between first pass and re-use water raceways at Umatilla Hatchery |
1996 |
We recommended continued production of steelhead in O2-supplemented raceways. We estimated 40% greater production per gallon of water. |
1996 |
We estimated angler effort of more than 2900 h and the quota of 206 spring chinook salmon was reached for the 1996 fishery. |
1996 |
Efforts began in 1996 to collect sufficient numbers of samples for ELISA from marked returning adults to make assessments of how rearing strategy might be affecting BKD and survival to adulthood. |
1997 |
A study to evaluate rearing subyearling fall chinook salmon at three densities was initiated. Growth and condition were similar for fish from all raceways. |
1997 |
We determined that wire tagging all fall chinook salmon should continue. Only 5 of 50 Umatilla fish that arrived at Lower Granite Dam escaped. Because wire-tagged fish were removed, we recommended elimination of the ventral fin clip. |
1997 |
We recommended that steelhead straying into the Umatilla basin should be addressed. More than 10% of returning adults were hatchery strays. As a result, tags from broodstock were examined prior to spawning. |
1997 |
Adult spring chinook salmon reared as juveniles at Bonneville and Umatilla Hatcheries and spawned at South Fork Walla Walla Adult Facility exhibited low or negative levels of Rs antigen. |
1998 |
We recommended earlier release of late-release steelhead. Survival of early-release groups averaged 0.83% compared to 0.13% for late group. |
1998 |
PIT-tagging was initiated as monitoring at John Day dam came online. Initial results suggested similar performance of fish reared at three densities, with larger fish performing best. |
1998 |
Pattern has become clearer in this Umatilla program that when chinook broodstocks are used with known clinical BKD females, the progeny either have low grade BKD loss or increased loss due to BKD. |
1999 |
Radio-telemetry monitoring of steelhead showed poor outmigration performance of groups released in May and management changes to improve survival were recommended. |
