  1. Variations in condition indices of mackerel icefish at South Georgia from 1972 to 1997

    index of condition which uses the ratio of the measured total mass to the estimated mass is show to ... provide a good indicator of local krill density. The index is likely to be little affected by the ... changes in hill density and therefore can provide indications of short term variations in krill ... availability. Condition index provides a useful proxy for krill density that is likely to be of considerable ...

    Shetland Islands, during January and February 1993, were analyzed to determine the importance of fish in ... the diet of the blue-eyed shag Phalacrocorax atriceps bransfieldensis. Fish species were identified by ... means of otoliths found in the casts. The size and weight of the fish were estimated from the otolith ... , comprising 91% of prey items. From the 937 otoliths found, 562 fish were represented and 524 were assigned to ...
