Catch and length/age composition data for Notothenia squamifrons from Ob and Lena Banks, Division 58.4.4, are presented for the period from 1978 to 1990 split years. These data were used in VPA analyses made for each bank separately. The CCAMLR VPA program, version 4.1 was used. The resulted biomass estimates for 1990 are 10.2 x 103 tonnes for Ob Bank and 20.7 x 103 tonnes for Lena Bank. These estimates may be used in calculation of TAC which in accordance with our calculations should be 2.0 x 103 tonnes for Ob Bank and 4.0 x 103 tonnes for Lena Bank.
