in the late summer probably were spawned 

 in early summer. The larg-er fish probably 

 were adults, for the maximum length of 

 this species is about 60 mm. (Bigelow and 

 Schroeder, 1953). 



Gasterosteus aculeatiiH Linnaeus, threespine 



.stickleback. 



The threespine sticklel^ack (table 7, fig. 3) 

 also was caught in shallow water near the 

 salt marsh. This species apjiarently 

 spawns in eai'ly summer in l)rackish to 

 fresh water (Bigelow and Schroeder, 

 1953); therefore, we assumed that the 

 small individuals 19 to 38 mm. long taken 

 in late June through Sej^tember were 0- 

 group fish.
