Zimmermann. Maturity and fecundity of Atheresthes stomias 
61 1 
Although this study provides the first information 
on total fecundity of arrowtooth flounders, sub- 
sampling of ovarian tissue for total fecundity, histol- 
ogy of males, comparison of macroscopic and histo- 
logical methods, and relation of ancillary body mea- 
sures such as CF, GSI, and HSI, there is still much 
that is unknown about this species. The lag of male 
maturity in comparison to that of females in this 
study, and the lack of spawning males in Rickey’s 
(1995) study are parts of an interesting riddle. Pos- 
sible seasonal migrations proposed by Shuntov ( 1970) 
and Rickey ( 1995) need to be thoroughly documented, 
as well as possible spawning migrations. Differences 
in size at maturity found in this study, compared with 
those found in studies conducted in southern waters, 
need to be explored. A study, in which collections are 
made at preselected depths and in which age and 
histological data are collected at regular intervals 
throughout a year, would answer many questions. 
Acknowledgments 
I would like to thank D. Somerton for suggesting this 
project and M. Wilkins for giving me the time to com- 
plete it. S. Hinckley, S. McDermott, N. Merati, D. 
Nichol, and M. Rickey provided helpful discussions 
on sampling design, processing, and analysis. In ad- 
dition, I would like to thank L. Mooney and F. Morado 
for teaching me histological processing and for use 
of their laboratory. D. Benjamin, J. Haaga, D. King, 
R. Macintosh, D. Smith, and D. Somerton assisted 
in collecting the samples.
