The relationships for carpenter (Argyrozona argyrozona) between (A) 

 fish length and batch fecundity including data from fish spawned 

 artificially in a previous study (Davis, 1996 I. (B) fish mass and 

 batch fecundity and (C) fish length and relative batch fecundity. 



oocytes and POFs were found from October to May). 

 Monthly spawning fraction and percentage of ovaries 

 with hydrated oocytes nevertheless reached a peak dur- 

 ing January and February (Table 2); these trends were 

 not detected in the monthly GSIs. But given that the 



macroscopic determinations of stage followed trends in 

 the proportions of POFs that were present, we conclude 

 that expensive and time-consuming histological analy- 

 sis is not necessary for determining spawning peaks 

 for this species.
