Hureau (1970) tried to fit a Bertallarify curve to his results from Terre Adelie but 

 could not obtain a realistic estimate for L oo . He therefore derived the follovjing altei^ 

 native equations. 



L^ = 3.2 (t) - 1.0 (5 t > 6) 



\ = 1.925 (t) + 6.9 (Cf t > 5) 

 A Bertallanfy curve was fitted to the results from the Slgny Island fish and the 

 constants are set out in Table 8.0.

Notothenia rossii 



Size at age has been studied at Kerguflen (llureau 1970) and also at South Georgia 

 (Olsen 1954, Crisp and Carrick 1975). These results are Bummarised in Tables 8.9 and 8.10.
