Abstract The use of sterile triploids in aquaculture is currently limited because reduced performance situations aerobic stress such as high temperature, hypoxia, and exhaustive exercise. Many studies have therefore attempted to find underlying metabolic differences between their diploid counterparts improve triploid rearing protocols. This study investigated the effects triploidy on postprandi...

Although invasion is widespread, documentation of historic versus recent invasion rates throughout drainages is lacking. We compared brook trout distributions in 1996 to those as early as 1971 for 17 streams in the upper South Fork Salmon Rive...
