1962 



1 Assumed to be young of the year on the basis of 

 data given by Bigelow and Schroeder (1953) and by 

 the seasonal progression of length frequency distribu- 

 tions in the 1961-G2 fish. 



December 1961 and in late March to De- 

 cember 1962 (table 15, fig. 3). Small 

 specimens about 35 to 50 mm. long, which 

 appeared in late March and were present 

 through the rest of the year as progres- 

 sively larger fish, probably were of a 

 single age-group of this species which 

 spawns in autumn and winter. These may 

 have been 0-group fish, because no smaller 

 specimens were caught; Bigelow and 

 Schroeder (1953) reported that the young 

 of this species are planktonic in the Woods 

 Hole ai-ea during late winter and spring. 



Dactylopteridae — flying gurnards 



Dactyloptenis volituns (Linnaeus), flying 



gurnard. 



A single flying gurnard, 69 mm. long, was 

 caught in August 19(52 (U.S. National 

 Museum catalog number US204318). 



Pholidae — gunnels 



Phulis gunvellus (Linnaeus), rock gunnel. 

 Seventeen rock gunnels were caught (table 

 16). A few of these — in particular one 

 72 mm. long taken in late November 1961 

 and one 55 mm. long in early August 1962 



dro]i in water temperature that was oc- 

 curring at this time (table 1, fig. 2). 



Cottidae — sculpins 



Mijo.voccjihalus octndpcemspinosus (Mitch- 

 ill), longhorn sculpin. 



Longhorn sculpins were caught in October 

 to Decemlier 1961 and in May and Octobe}- 

 to December 1962 (table 14, fig. 3) . While 

 no measurements were oljtained for the 

 1961 fi.sh, they were similar in size to tho.se 

 from 1962. All of the fish were assumed 

 to be adults. The increase in numbers in 

 November apparently was related to 

 spawning, which occurs in inshore areas 

 at about this time (Bigelow and Schroeder, 

 1953). 



Myoxocejihahis aenens (Mitchill), grubby. 

 Grubbies were caught in November and
