5. Evidence to support the annual formation of growth zones in otoliths of Antarctic toothfish (Dissostichus mawsoni)

   Abstract:  Antarctic toothfish (Dissostichus mawsoni) from the Ross Sea (CCAMLR sub-area 88.1 ... ) have been aged assuming that one translucent zone is formed annually in the otoliths of this species ... . However, no evidence to validate this assumption has previously been presented. In the current work ... before recapture. The number of zones between the fluorescent oxytetracycline line and the otolith margin ...

   Abstract:  The summer 1998 AMLR field season followed late-forming but spatially extensive winter ... sea ice in the Antarctic Peninsula region. Overall krill length/maturity composition reflected poor ... recruitment from the past two years. Unusually small juvenile krill in 1998 suggested that survival success ... during the 1993 "salp year". The magnitude of this salp bloom may have resulted from a large ...
