proposed a spring or late winter-early spring 

 spawning period (Hildebrand 1954; Miller 1965; 

 Chittenden and McEachran 1976) based on the 

 captures of fish 106-159 mm TL with well-devel- 

 oped gonads in February (Hildebrand 1954) and 

 fish 31-89 mm TL in early May and June (Cald- 

 well 1955; Miller 1965). Henwood's (1975) histo- 

 logical studies indicated spawning from Novem- 

 ber through April, but our data indicate little or 

 no spawning before January. Our finding that
