Progression and severity of gas bubble trauma in juvenile salmonids Progression and severity of gas bubble trauma in juvenile salmonids
We conducted laboratory experiments to assess the progression and to quantify the severity of signs of gas bubble trauma (GBT) in juvenile chinook salmon Oncorhynchus tshawytscha and steelhead Oncorhynchus mykiss exposed to different levels of total dissolved gas (TDG), and we attempted to relate these signs to the likelihood of mortality. When fish were exposed to 110% TDG for up to 22...

Prevalence of Renibacterium salmoninarum in juvenile spring chinook salmon at Columbia and Snake river hatcheries, 1993-1996 Prevalence of Renibacterium salmoninarum in juvenile spring chinook salmon at Columbia and Snake river hatcheries, 1993-1996
We monitored the prevalence and severity of Renibacterium salmoninarum (RS) infections in juvenile hatchery spring chinook salmon Oncorhynchus tshawytscha at eight Columbia and Snake river hatcheries from 1993 through 1996. This study followed a prior study that monitored RS in the same hatcheries from 1988 through 1992. In the current study, we found that the prevalence of RS-positive...

Cloning, in Vitro expression, and novel phylogenetic classification of a channel catfish estrogen receptor Cloning, in Vitro expression, and novel phylogenetic classification of a channel catfish estrogen receptor
We obtained two channel catfish estrogen receptor (ccER) cDNA from liver of female fish using RT–PCR. The two fragments were identical in sequence except that the smaller one had an out-of-frame deletion in the E domain, suggesting the existence of ccER splice variants. The larger fragment was used to screen a cDNA library from liver of a prepubescent female. A cDNA was obtained that...

Rate of disappearance of gas bubble trauma signs in juvenile salmonids Rate of disappearance of gas bubble trauma signs in juvenile salmonids
To assess the rate of disappearance of gas bubble trauma (GBT) signs in juvenile salmonids, we exposed spring chinook salmon Oncorhynchus tshawytscha and steelhead O. mykiss to water containing high levels of dissolved gas supersaturation (DGS) for a time period sufficient to induce signs of GBT, reduced the DGS to minimal levels, and then sampled fish through time to document changes in...
