14. Fluctuations in the catch of winter flounder in several monitoring 

 programs were analyzed using time-based harmonic regression models. 

 The best models were developed with impingement and entrainment 

 data. Models using data from the trawl monitoring program were 

 inadequate, which may have been a result of variability in the data 

 or because the winter flounder has a cycle of abundance greater 

 than the 6-year period used in the models.
