Blue-eyed shags as indicators of changes in ittora fish populations
Abstract: The use of Shag’s pellets as an appropriate technique to monitor the abundance of littoral fish populations is presented for consideration of the CCAMLR Ecosystem Monitoring Program Working Group. The effectiveness of the method is based on the very good agreement found between the fish

The diet of the blue-eyed shag, Phalacrocorax atriceps bransfieldensis at the west Antarctic Peninsula
Abstract: The diet of the Antarctic Blue-eyed Shag Phalacrocorax atriceps bransfieldensis was analyzed based on the identification of the prey items in 50 regurgitated casts collected at Duthoit Point, Nelson Island, in February 1991. Benthic organisms, chiefly fish, were found to be the main

An iterative model to construct an age-length key to assess the age composition of a new fishery for Dissostichus eleginoides in Chilean waters
Abstract: Traditional calculation of catch age composition estimate requires that the age-length data and random length frecuency be sampled from the same population, in other case an age-length key is capable of providing biased estimates of age distribution. By using the iteration algorithm is

A brief outline of the biology of the Antarctic silverfish, Pleuragramma antarcticum Boulenger, 1902 (Nototheniidae) from the Antarctic Indian Ocean
Abstract: The Antarctic silver fish (Pleuragramma antarcticum) is one of the most numerous species in the outer waters of Antarctica. In the Indian sector of the Southern Ocean there are at least three relatively isolated groups. Fish aged from 0+ to 3+ years live in the epi- mesopelagic zone

CCAMLR ecosystem monitoring and a feedback management procedure for krill
Abstract: The CCAMLR Ecosystem Monitoring Programme has been developing a techniques-which might detect short term declines in land-based predator performance (eg. reproductive performance) that may be attributable to loss of prey through fishing activities. The principal fishery in the CCAMLR

Assessment of the stocks of abundant fish species in the South Georgia subarea (48.3) made on the basis of data obtained from the RV Atlantida trawl survey of April/May 1991
Abstract: The seventh cruise of the RV Atlantida was a continuation of regular AtlantNIRO research into the status of Chaenichthyidae and Nototheniidae fish in Statistical Subarea 48.3 (South Georgia, Shag Rocks and Black Rocks). The minimum biomass of commercial fish species was calculated from

Homogeneity of body length composition of Antarctic krill within the commercial haul
Abstract: The homogeneity of krill length composition in commercial trawl catches (hauls) was investigated by comparing length compositions from different parts of the same haul. There was no significant difference (P>0.05) in 53 out of 60 hauls. Therefore it is concluded that sampling from one
