tive adults to ensure egg production and avoid recruit- 

 ment failure. To address proper management of line- 

 caught fish in South Africa, spawner biomass per re- 

 cruit models have been used (Griffiths, 1997). One as- 

 sumption of this approach is that fecundity is linearly 

 related to spawning biomass, regardless of individual 

 size (Buxton, 1992). Because our study has shown 

 that fecundity in carpenter is allometrically related to 

 individual mass, egg-per-recruit models would be 

 more appropriate for future stock assessment of this 

 species.
