Abstract
Chromosome set manipulation was used to produce rainbow trout, Oncorhynchus mykiss, with identical nuclear backgrounds, but different maternal backgrounds to determine mitochondrial effects on development rate and oxygen consumption. Significant differences in development rate and oxygen consumption were observed between groups from different females. Development rates ranged from a mean of 317.97 degree days ( degrees d) to 335.25 degrees d in progeny from different females. Mean oxygen consumption rates ranged from 3.31 micromol O2 g(-1) wet mass h(-1) to 9.66 micromol O2 g(-1) wet mass h(-1). Oxygen consumption and development rate analysis revealed the two slowest developing groups had the highest oxygen consumption rates. Development rate differences between second generation clonal females indicate that mitochondrial genomes play a significant role on early development and are comparable to development rate differences between clonal lines of rainbow trout. These results indicate that selection for mitochondrial genomes could increase growth rates and possibly food conversion ratios in aquaculture species.
