AB  - Fall spawning pacific salmon provision large amounts of yolk to their eggs to 
      allow survival of larvae during under the ice winter conditions. This yolk 
      provisioning leads to maternal offloading of persistent organic pollutants (POPs) 
      to eggs and larvae. Previous research has shown that Chinook salmon larvae 
      exhibit limited capacity to eliminate POPs during the cold water period resulting 
      in bioamplification of POP residues. This study compared POPs bioamplification in 
      Chinook salmon larvae under a high food provisioning treatment and a non-fed 
      treatment to test whether or not food availability attenuates POPs 
      bioamplification via growth dilution. Results demonstrate that larvae in the food 
      provisioning treatment did not gain weight until after day 129. Between hatching 
      and day 129, fed and non-fed treatments exhibited similar decreases in whole body 
      lipid content, negligible POPs elimination and POPs bioamplification factors 
      approaching 1.6. By day 184 of the study, POPs bioamplification factors in the 
      non-fed treatment were as high as 5.3 across chemicals but ranged from 
      non-detectable to approaching 1 in the fed group. This study demonstrates that 
      POPs bioamplification occurs in Chinook salmon larvae even under ideal rearing 
      conditions but peaks after day 129, following which growth dilution can attenuate 
      bioamplification relative to starved individuals.
