Abstract

From July to October 1977, during the polar winter and at the beginning of spring, line-fishing was carried out at Admiralty Bay, near the Arctowski Station on King George Island, (South Shetland Islands). At that time only three species of fish were caught: Notothenia rossi marmorata, Notothenia coriiceps neglecta and Trematomus newnesi. Fish was caught in the irshore zone at depths ranging from 2 to 40—60 m.

Abstract

Blood of 71 specimens of Notothenia rossii marmorata and 61 specimens of Notothenia neglecta from the region of Admiralty Bay (King George Island) was examined. The number of erythrocytes and hemoglobin content were higher in the blood of N. neglecta. The number of erythrocytes and hemoglobin content were similar in males and females of both species. Considerable differences were noted between individual specimens.

Abstract

232 specimens of Notothenia coriiceps neglecta and 578 specimens of Notothenia rossi marmorata were collected in the region of Admiralty Bay during the period from March to December 1977. The age of the fish was determined from scales. Length — weight relationship was calculated for both species. The parameters of the von Bertalanffy equation were calculated for Notothenia coriiceps neglecta, whereas mean lengths for Notothenia rossi marmorata were given according to the particular age groups.
