Some additional refinement of the the techniques has been suggested 

 by this review as well as further analysis in some areas. A brief 

 summary and discussion of each item follows. 

 Item 



1. The accuracy and usefulness of the 1975 population estimate is 

 questioned. 

 Comment 



The 1975 survey was originally designed for the triple-trellis 

 technique, thus recaptures were never marked. The data had to be manipu- 

 lated based on a simulation of multiple recaptures to provide a Jolly 

 estimate and the phenomenon of temporary outmigration could not be 

 examined. The survey period was brief (only 4 weekly estimates made) 

 and didn't commence until March 31, nearly the end of the spawning 

 period. The calculated probability of survival (phi) was greatly above 

 1.00 during 2 of the 4 weeks, indicating a major error (Southwood 1978). 

 For these reasons the 1975 estimate must be viewed with some suspicion 

 and the numbers used with care in any analyses. This is not to say that 

 the data are entirely without merit. There is no doubt that winter 

 flounder were particularly abundant in 1975 as evidenced by the weekly 

 CPUE, especially in late April and early May (Table 16) . These figures 

 and other life history information will continue to be useful in future 

 analyses. 

 Item 



2 . The accuracy and usefulness of the 1980 population estimate is 

 questioned.
